Best Weight Loss Medication 2026: Complete GLP-1 Comparison Guide

Tirzepatide (Zepbound, Mounjaro) is the most effective weight loss medication in 2026, producing 15-22% average body weight loss in clinical trials, followed closely by semaglutide (Wegovy, Ozempic) with 10-15% average weight loss, with both significantly outperforming all other FDA-approved weight loss medications. 

If you’re researching prescription weight loss options, understanding the dramatic effectiveness advantage of GLP-1 medications over older alternatives helps you make informed decisions about your weight loss journey.

The landscape of weight loss medication has been revolutionized by GLP-1 and dual GIP/GLP-1 receptor agonists. These medications work through multiple mechanisms—reducing appetite, slowing digestion, and affecting brain hunger centers—producing weight loss results that were previously only achievable through bariatric surgery. 

TrimRx provides access to both compounded semaglutide ($199/month) and compounded tirzepatide ($349/month), making the most effective weight loss medications affordable and accessible.

Why GLP-1 Medications Dominate:

The top three most effective medications are all GLP-1 receptor agonists. These medications work through multiple complementary mechanisms:

Appetite Regulation:

• Activate receptors in brain’s appetite centers
• Reduce hunger signals
• Increase feelings of fullness
• Decrease food cravings

Gastric Effects:

• Slow stomach emptying
• Prolong satiety after meals
• Reduce portion sizes naturally

Metabolic Benefits:

• Improve insulin sensitivity
• Better blood sugar control
• Reduce inflammation
• Positive cardiovascular effects

The combination of these effects produces weight loss 2-4x greater than older medications.

FDA Approval Criteria:

For FDA approval as weight loss medication, drugs must demonstrate:

Efficacy Requirements:

• At least 5% average weight loss greater than placebo
• At least 35% of patients lose ≥5% body weight
• At least 15% of patients lose ≥10% body weight

Safety Requirements:

• Acceptable safety profile in clinical trials
• Benefits outweigh risks
• Appropriate for long-term use

All newer GLP-1 medications far exceed the minimum efficacy requirements, which explains their dominance.

Off-Label Use:

Some medications are prescribed “off-label” for weight loss:

Semaglutide (Ozempic):

• FDA-approved for type 2 diabetes (not weight loss)
• Identical to Wegovy but different indication
• Commonly prescribed off-label for weight loss
• Same effectiveness as Wegovy

Tirzepatide (Mounjaro):

• FDA-approved for type 2 diabetes (not weight loss)
• Identical to Zepbound but different indication
• Prescribed off-label for weight loss before Zepbound approval
• Same effectiveness as Zepbound

Metformin:

• Diabetes medication sometimes used for weight loss
• Produces only 1-3% weight loss
• Not FDA-approved for weight loss
• Generally not recommended as primary weight loss medication

The Current State of Weight Loss Medication:

Clear Winners: GLP-1 receptor agonists (especially tirzepatide and semaglutide) have become the gold standard for medical weight loss, producing results previously unattainable with medication alone.

Outdated Options: Older medications like orlistat and naltrexone-bupropion are still FDA-approved but rarely prescribed by weight loss specialists due to poor effectiveness and tolerability.

Future Pipeline: Multiple pharmaceutical companies are developing next-generation weight loss medications, including:

• Oral GLP-1 formulations
• Triple agonist medications (GIP/GLP-1/glucagon)
• Long-acting formulations (monthly injections)

Understanding the best GLP-1 weight loss programs helps you access these highly effective medications affordably.

GLP-1 Medications: The Gold Standard

GLP-1 (glucagon-like peptide-1) receptor agonists represent a breakthrough in weight loss medication, producing results that rival bariatric surgery without requiring invasive procedures.

Why GLP-1s Are Revolutionary:

Historical Context:

Before GLP-1 medications:

• Weight loss medications produced 3-7% average weight loss
• Only bariatric surgery achieved 15-30% weight loss
• Many people couldn’t access surgery due to cost, risk, or preferences
• Gap existed between ineffective pills and invasive surgery

GLP-1s filled this gap:

• Producing 10-22% weight loss with medication alone
• Non-surgical option with bariatric-level results
• Relatively few contraindications
• Once-weekly administration
• Generally well-tolerated

How GLP-1 Medications Work:

Natural Hormone Mimicry:

GLP-1 is a hormone your body naturally produces in your intestines after eating. It signals:

• “You’re full, stop eating”
• “Produce insulin to handle this food”
• “Don’t release stored glucose from liver”

GLP-1 medications are synthetic versions that:

• Last much longer than natural GLP-1 (days vs. minutes)
• Activate same receptors at higher, sustained levels
• Produce therapeutic effects natural GLP-1 can’t maintain

Multiple Mechanisms of Action:

Brain Effects:

• Cross blood-brain barrier
• Activate GLP-1 receptors in hypothalamus (appetite control center)
• Reduce reward response to food
• Decrease food cravings and obsessive food thoughts
• Increase feelings of satiety

Stomach Effects:

• Slow gastric emptying (food stays in stomach longer)
• Increase time to feel hungry again
• Reduce portion sizes naturally (feel full with less food)
• Decrease frequency of eating

Pancreas Effects:

• Increase insulin secretion when blood sugar is elevated
• Improve beta cell function
• Decrease glucagon (prevents excess glucose production)
• Better blood sugar control

Metabolic Effects:

• Improve insulin sensitivity
• Reduce inflammation
• Lower blood pressure
• Improve lipid profiles
• Reduce cardiovascular disease risk

Types of GLP-1 Medications:

Pure GLP-1 Agonists:

• Semaglutide (Wegovy, Ozempic)
• Liraglutide (Saxenda, Victoza)
• Dulaglutide (Trulicity)
• Exenatide (Byetta, Bydureon)

Dual GIP/GLP-1 Agonist:

• Tirzepatide (Zepbound, Mounjaro)
• Activates both GIP and GLP-1 receptors
• More potent than pure GLP-1 agonists
• Represents next generation of medications

Why Dual Agonists Are More Effective:

GIP (Glucose-Dependent Insulinotropic Polypeptide) adds:

• Additional insulin secretion
• Improved insulin sensitivity
• Effects on fat metabolism
• Synergistic appetite suppression with GLP-1
• Better overall metabolic improvements

Result: 5-7% more weight loss than semaglutide alone

Clinical Trial Success:

STEP Program (Semaglutide):

• STEP 1: 14.9% weight loss vs 2.4% placebo
• STEP 2 (diabetes): 9.6% weight loss
• STEP 3 (with lifestyle): 16.0% weight loss
• STEP 4 (maintenance): Continued loss with treatment, regain when stopped

SURMOUNT Program (Tirzepatide):

• SURMOUNT-1: 22.5% weight loss vs 2.4% placebo
• SURMOUNT-2 (diabetes): 15.7% weight loss
• SURMOUNT-3 (maintenance): Additional 5.5% loss when continued
• SURMOUNT-4: 25.3% weight loss with maximum protocol

Real-World Effectiveness:

Studies of patients using GLP-1s outside clinical trials show:

• Similar weight loss to trials (real-world effectiveness confirmed)
• High patient satisfaction
• Most side effects manageable
• Many patients continue long-term
• Weight regain occurs if stopped (as expected)

Safety Profile:

Common Side Effects:

• Nausea (30-44% depending on medication)
• Diarrhea (19-30%)
• Constipation (10-24%)
• Vomiting (9-24%)
• Abdominal discomfort

Most side effects:

• Occur during dose escalation
• Improve over 4-8 weeks
• Manageable with dietary adjustments
• Rarely require discontinuation

Serious Risks (Rare):

• Pancreatitis (<1%)
• Gallbladder problems (related to rapid weight loss)
• Thyroid tumors (seen in rodents, not confirmed in humans)
• Kidney problems (usually from dehydration)

Contraindications:

• Personal or family history of medullary thyroid carcinoma
• Multiple endocrine neoplasia syndrome type 2 (MEN 2)
• Pregnancy or planning pregnancy
• History of severe GLP-1 allergic reaction

Long-Term Safety:

Semaglutide:

• SELECT trial: 20% reduction in major cardiovascular events

• Cost: $1,069/month
• Note: Identical to Zepbound, prescribed off-label for weight loss

Compounded Tirzepatide:

• Source: FDA-registered compounding pharmacies
• Indication: Prescribed for weight loss by licensed providers
• Doses: Custom concentrations available
• Cost: $349-$699/month
• Same active ingredient as Zepbound/Mounjaro

Why Tirzepatide Is More Effective:

Dual Mechanism:

GLP-1 Effects (Same as Semaglutide):

• Appetite suppression through brain receptors
• Slowed gastric emptying
• Increased insulin secretion
• Decreased glucagon production

Additional GIP Effects:

• Enhanced insulin response beyond GLP-1 alone
• Improved insulin sensitivity in tissues
• Effects on fat metabolism and energy expenditure
• Synergistic appetite reduction
• Additional weight loss mechanisms

Result: The combination produces 5-7% more weight loss than GLP-1 agonists alone.

Clinical Effectiveness:

SURMOUNT-1 Trial (Tirzepatide 15 mg):

• Duration: 72 weeks
• Participants: 2,539 adults with obesity
• Average Weight Loss: 22.5% of body weight
• 10 mg Dose: 21.4% weight loss
• 5 mg Dose: 15.0% weight loss
• Placebo: 2.4% weight loss
• ≥5% Weight Loss: 96% of participants
• ≥10% Weight Loss: 89% of participants
• ≥15% Weight Loss: 78% of participants
• ≥20% Weight Loss: 63% of participants

This is the best weight loss result ever achieved with medication in clinical trials.

Real-World Examples:

250-Pound Person:

• Average loss: 56 pounds (22.5%)
• Final weight: 194 pounds
• Timeline: 18-20 months

200-Pound Person:

• Average loss: 45 pounds (22.5%)
• Final weight: 155 pounds
• Timeline: 18-20 months

300-Pound Person:

• Average loss: 67 pounds (22.5%)
• Final weight: 233 pounds
• Timeline: 20-24 months

Dosing Schedule:

Standard Escalation:

• Weeks 1-4: 2.5 mg weekly (starting dose)
• Weeks 5-8: 5 mg weekly
• Weeks 9-12: 7.5 mg weekly
• Weeks 13-16: 10 mg weekly (if tolerating well)
• Weeks 17-20: 12.5 mg weekly (if needed)
• Week 21+: 15 mg weekly (maximum dose for weight loss)

Flexible Dosing:

• Not everyone needs maximum 15 mg dose
• Many achieve excellent results at 10 mg
• Provider adjusts based on results and tolerance
• Can stay at effective dose rather than pushing to maximum

Side Effects:

Most Common:

• Nausea: 30-37% (lower than semaglutide despite higher potency)
• Diarrhea: 19-23%
• Vomiting: 9-17%
• Constipation: 10-17%
• Abdominal discomfort: 8-11%

Interesting Finding: Despite being more potent, tirzepatide causes less nausea and vomiting than semaglutide. Researchers believe GIP activation may counterbalance some GLP-1 gut effects.

Discontinuation Rate: 6.2% due to side effects (similar to semaglutide)

Side Effect Comparison:

Side Effect	Semaglutide	Tirzepatide	Winner
Nausea	44%	30-37%	Tirzepatide
Diarrhea	30%	19-23%	Tirzepatide
Vomiting	24%	9-17%	Tirzepatide
Constipation	24%	10-17%	Tirzepatide
Weight Loss	14.9%	22.5%	Tirzepatide

Tirzepatide produces better results with fewer side effects—a rare win-win.

Who Should Choose Tirzepatide:

Ideal Candidates:

• Need maximum weight loss (50+ pounds)
• Want most effective medication available
• Can afford $349-$1,069/month depending on option
• Have BMI ≥30 (or ≥27 with comorbidities)
• Plateaued on semaglutide or other medications
• No contraindications to GLP-1/GIP agonists

Particularly Good For:

• Significant obesity (BMI ≥35)
• Previous weight loss medication failures
• Those who want best possible results
• Patients who tolerate GLP-1s well

• Three times daily with meals
• Must take with or within 1 hour of meals containing fat

Cost:

• Prescription (Xenical 120 mg): $100-$200/month
• OTC (Alli 60 mg): $40-$60/month

Who Should Consider:

• Very few patients benefit
• May be option if all other medications contraindicated
• Extremely motivated to follow low-fat diet
• Don’t mind frequent GI side effects

Most weight loss specialists don’t recommend orlistat due to poor effectiveness and troublesome side effects.

Phentermine (Adipex-P):

What It Is:

• Sympathomimetic amine (stimulant)
• Appetite suppressant
• Oldest weight loss medication still available

Effectiveness:

• Average Weight Loss: 5-7% of body weight
• Short-term use only (FDA-approved for 12 weeks)
• Weight often regained after stopping

Mechanism:

• Stimulates norepinephrine release
• Decreases appetite
• Increases energy expenditure

Side Effects:

• Increased heart rate and blood pressure
• Insomnia
• Nervousness, anxiety
• Dry mouth
• Constipation
• Potential for dependence

Major Limitations:

• Controlled substance (Schedule IV)
• FDA-approved for short-term only (12 weeks)
• Not a long-term solution
• Cardiovascular concerns
• Risk of abuse

Cost:

• Generic: $20-$50/month
• Usually not covered by insurance

Who Should Consider:

• Need short-term appetite suppression
• Kickstart weight loss before switching to long-term option
• Can’t afford other medications
• No cardiovascular disease or substance abuse

Most experts don’t recommend phentermine due to short-term limitation and rebound weight gain.

Liraglutide (Saxenda):

What It Is:

• GLP-1 receptor agonist (same class as semaglutide)
• Older, less effective version
• Daily injection required

Effectiveness:

• Average Weight Loss: 5-8% of body weight
• SCALE Trial: 8% loss vs 2.6% placebo
• Significantly less effective than semaglutide (daily) or tirzepatide

Why Less Effective:

• Shorter half-life requires daily dosing
• Less consistent drug levels
• Lower peak concentrations

Side Effects:

• Similar to semaglutide (nausea, diarrhea, constipation)
• Same GLP-1 class warnings

Cost:

• $1,400/month
• More expensive than newer, more effective options

Who Should Consider:

• Almost no one
• Semaglutide and tirzepatide have largely replaced liraglutide
• Rarely prescribed for weight loss anymore

Comparison Table: All FDA-Approved Weight Loss Medications:

Medication	Weight Loss	Administration	Cost/Month	Rank
Tirzepatide	15-22%	Weekly injection	$349-$1,069	#1
Semaglutide	10-15%	Weekly injection	$199-$1,349	#2
Phentermine-Topiramate	7-9%	Daily pill	$150-$250	#3
Liraglutide	5-8%	Daily injection	$1,400	#4
Phentermine	5-7%	Daily pill	$20-$50	#5
Naltrexone-Bupropion	4-5%	Daily pill (2x/day)	$100-$250	#6
Orlistat	3-5%	3x/day with meals	$40-$200	#7

Bottom Line on Non-GLP-1 Options:

For most patients seeking effective weight loss:

• Best Results: Tirzepatide or semaglutide
• If GLP-1s Contraindicated: Phentermine-topiramate
• Avoid: Orlistat, naltrexone-bupropion (poor effectiveness)
• Short-term Only: Phentermine

The GLP-1 revolution has made older medications largely obsolete for patients who can tolerate them.

Effectiveness Comparison: Which Works Best?

Based on clinical trial data and real-world results, tirzepatide is the clear winner for weight loss effectiveness.

Clinical Trial Results Ranked:

Rank	Medication	Average % Weight Loss	Trial Name	Duration

• Conclusion: Need ongoing treatment

Phentermine:

• FDA-approved for 12 weeks only
• Weight regain after stopping is universal
• Not a long-term solution

All Weight Loss Medications:

• Obesity is chronic disease
• Medications treat symptoms, don’t cure
• Stopping medication → weight regain
• Long-term or indefinite use necessary for sustained results

Safety Profile Comparison:

Discontinuation Due to Side Effects:

• Tirzepatide: 6.2%
• Semaglutide: 6.9%
• Liraglutide: 9.9%
• Naltrexone-bupropion: 25% (very high)
• Orlistat: 15-20%
• Phentermine-topiramate: 8-10%

GLP-1s have excellent tolerability considering their effectiveness.

Serious Adverse Events:

• All medications: <2% in clinical trials
• No medication dramatically safer than others
• Risk-benefit strongly favors most effective options

Cost-Effectiveness Analysis:

Cost Per Pound Lost (18-month treatment):

Phentermine-Topiramate	$4,050	23	$176
Naltrexone-Bupropion	$3,600	12	$300

Compounded GLP-1s offer the best combination of effectiveness and cost-effectiveness.

Expert Consensus:

American College of Physicians: “GLP-1 receptor agonists should be considered for patients with obesity who have not achieved weight loss goals with lifestyle modifications.”

Endocrine Society: “Semaglutide and tirzepatide represent significant advances in obesity pharmacotherapy and should be considered first-line options.”

Obesity Medicine Association: “The dramatic efficacy of GLP-1 and dual agonist medications has fundamentally changed the treatment landscape for obesity.”

Real-World Effectiveness:

Studies of patients using these medications outside clinical trials show:

• GLP-1s: Similar to clinical trial results (confirming real-world effectiveness)
• Older medications: Often less effective in real-world than trials (adherence issues)
• Patient satisfaction: Highest with GLP-1s

Bottom Line: Which Works Best?

For Maximum Weight Loss:

1. Tirzepatide (22.5% average loss)
2. Semaglutide (14.9% average loss)
3. Distant third: Phentermine-topiramate (9.3% loss)

For Best Value:

1. Compounded semaglutide ($97 per pound lost)
2. Compounded tirzepatide ($112 per pound lost)
3. Others significantly worse

For Most Patients: Compounded semaglutide or compounded tirzepatide provide the best combination of effectiveness, tolerability, and affordability.

Understanding how to buy semaglutide online safely ensures you get legitimate medication at fair prices.

How to Choose the Right Medication for You

Selecting the best weight loss medication depends on your individual goals, health status, budget, and preferences.

Step 1: Define Your Goals

Weight Loss Target:

Need to lose 20-40 pounds:

• Semaglutide sufficient (14.9% average loss)
• Less expensive option works well
• Compounded semaglutide at $199/month

Need to lose 50+ pounds:

• Tirzepatide preferred (22.5% average loss)
• Maximum effectiveness important
• Compounded tirzepatide at $349/month

Need to lose 100+ pounds:

• Tirzepatide strongly recommended
• May still need bariatric surgery after medication
• Medication can help even if surgery eventual goal

Timeline:

Want faster results:

• Tirzepatide produces weight loss slightly faster
• But both require 16-20 months for full results
• No medication produces safe, sustainable rapid weight loss

Have time for gradual approach:

• Either medication works
• Semaglutide more affordable for extended timeline

Step 2: Assess Your Health Status

Medical Conditions:

Type 2 Diabetes:

• Both semaglutide and tirzepatide excellent choices
• Provide blood sugar control plus weight loss
• May allow reducing other diabetes medications

Cardiovascular Disease:

• Semaglutide proven to reduce heart attacks/strokes (SELECT trial)
• May be preferred if heart disease history
• Tirzepatide cardiovascular trial ongoing

Thyroid Cancer or MEN 2 History:

• Absolute contraindication to all GLP-1s
• Must use non-GLP-1 options (phentermine-topiramate)

Gastrointestinal Disorders:

• GLP-1s may worsen gastroparesis
• Consider if severe GERD or chronic GI issues
• Discuss with provider

Pregnancy Plans:

• Do not use GLP-1s if pregnant or planning pregnancy
• Stop 2 months before trying to conceive
• Choose non-GLP-1 option or delay treatment

Previous Pancreatitis:

• Relative contraindication to GLP-1s
• Use with caution, close monitoring
• May be safer to avoid

Current Medications:

Insulin or Sulfonylureas:

• GLP-1s may cause low blood sugar when combined
• Need to reduce diabetes medication doses
• Close monitoring required

Blood Thinners:

• GLP-1s safe with anticoagulants
• No contraindication

Psychiatric Medications:

• Generally compatible with GLP-1s
• Naltrexone-bupropion may have more interactions

Step 3: Evaluate Your Budget

What Can You Afford Long-Term?

$150-$250/month:

• Compounded semaglutide at $199/month
• Best value for effectiveness
• Sustainable long-term

$300-$400/month:

• Compounded tirzepatide at $349/month
• Maximum effectiveness
• Still affordable vs. brand-name

$500-$1,000+/month:

• Brand-name options if insurance covers
• Unnecessary if paying cash (compounded same effectiveness)

Less than $150/month:

• Phentermine-topiramate ($150-$200)
• Phentermine alone ($20-$50, but short-term only)
• Consider if GLP-1s not affordable yet

Remember: Budget for 18-24 months minimum, plus maintenance phase

Step 4: Consider Administration Preferences

Comfortable with Weekly Injections:

• Semaglutide or tirzepatide (best effectiveness)
• Small needles, subcutaneous (not intramuscular)
• Most people find easier than expected

Prefer Daily Pills:

• Phentermine-topiramate (less effective but oral)
• Naltrexone-bupropion (least effective oral option)
• Oral semaglutide (Rybelsus) exists but much less effective

Needle Phobia:

• Try cognitive behavioral therapy first
• Consider that better results may outweigh discomfort
• If truly can’t inject: phentermine-topiramate
• Learn about oral tirzepatide development (not yet available)

Step 5: Assess Side Effect Tolerance

Sensitive to Nausea:

• Tirzepatide has lower nausea rates than semaglutide
• Start at lowest dose, escalate slowly
• Consider anti-nausea medication
• Most nausea improves after 4-8 weeks

GI Issues:

• All GLP-1s cause some GI effects initially
• Usually manageable with diet adjustments
• Improves significantly over time

Prefer Minimal Side Effects:

• GLP-1s still best choice despite side effects
• 93% of patients tolerate well enough to continue
• Benefits outweigh temporary discomfort for most

Step 6: Factor in Convenience

Prefer Telehealth:

• Compounded options through TrimRx
• Complete process online
• No in-person visits required
• Medication ships to door

Have Good In-Person Provider:

• Can prescribe brand-name or compounded
• Continue relationship if working well
• May still choose compounded for cost savings

Want Ongoing Support:

• Choose provider with included follow-ups
• Look for coaching or nutritionist access
• Community support valuable

Frequently Asked Questions

What is the most effective weight loss medication in 2026? Tirzepatide (Zepbound, Mounjaro) is the most effective weight loss medication, producing 15-22% average body weight loss in clinical trials—significantly better than all other FDA-approved options. Semaglutide (Wegovy, Ozempic) is the second most effective at 10-15% average weight loss. Both dramatically outperform older medications like phentermine-topiramate (7-9%) and naltrexone-bupropion (4-5%).

How much weight can you lose with GLP-1 medications? With tirzepatide, patients lose an average of 15-22% of body weight (40-56 pounds for a 250-pound person). With semaglutide, patients lose an average of 10-15% of body weight (25-37 pounds for a 250-pound person). Results vary individually, but 89% of tirzepatide users and 69% of semaglutide users lose at least 10% of their body weight.

Are weight loss medications safe for long-term use? Yes, GLP-1 medications (semaglutide and tirzepatide) have been proven safe for long-term use in clinical trials lasting up to 2+ years. The most common side effects—nausea, diarrhea, constipation—typically improve after the first 4-8 weeks. Semaglutide has been proven to reduce cardiovascular events by 20%, demonstrating health benefits beyond weight loss. Most patients need long-term treatment to maintain weight loss.

What is the cheapest effective weight loss medication? Compounded semaglutide at $199/month provides the best combination of effectiveness and affordability, producing 10-15% average weight loss at 85% less cost than brand-name Wegovy ($1,349/month). This makes highly effective GLP-1 treatment accessible to cash-pay patients who can’t afford brand-name prices.

Do I need a prescription for weight loss medication? Yes, all FDA-approved weight loss medications require a prescription from a licensed healthcare provider. Legitimate telehealth platforms like TrimRx connect you with licensed providers who can prescribe after appropriate medical evaluation. Any source offering prescription weight loss medications without a prescription is operating illegally.

Which is better for weight loss: semaglutide or tirzepatide? Tirzepatide produces superior results—22.5% average weight loss versus 14.9% with semaglutide. However, semaglutide costs less ($199 compounded vs $349 for tirzepatide) and still provides excellent weight loss. Choose tirzepatide for maximum results or semaglutide for best value. Compare both medications in detail.

How long does it take to see results with weight loss medication? Most people notice reduced appetite within 1-2 weeks of starting GLP-1 medications. Measurable weight loss typically begins by weeks 4-8 and continues steadily for 16-20 months. Average patients lose 5-8% of body weight in the first 3 months, 10-15% by 6 months, and reach maximum weight loss around 16-20 months.

Can I use weight loss medication if I have diabetes? Yes, both semaglutide and tirzepatide are excellent choices for patients with type 2 diabetes. Both medications were originally approved for diabetes treatment and provide excellent blood sugar control along with weight loss. Many patients can reduce or eliminate other diabetes medications after starting GLP-1 therapy. Consult your provider about adjusting diabetes medications.

Will insurance cover prescription weight loss medication? Insurance coverage for weight loss medications varies significantly. Some plans cover semaglutide (Wegovy) or tirzepatide (Zepbound) with copays of $25-$300/month, but many plans don’t cover weight loss medications or require extensive prior authorization. Compounded versions are rarely covered by insurance but cost less than most brand-name copays and can be purchased with HSA/FSA funds.

What happens when you stop taking weight loss medication? Clinical trials show that most patients regain significant weight when they stop GLP-1 medications. Obesity is a chronic condition, and medications treat symptoms rather than cure the underlying condition.
