Waking up with a painful calf cramp, or feeling your feet and hands tighten during the day, can be alarming. Muscle cramps are not usually listed among the classic side effects of Ozempic or another GLP-1. But they are something people do report, and they are often linked to the changes in eating and drinking that come with treatment.<\/p>\n
Here is what may be behind them and what helps.<\/p>\n
Occasional muscle cramps can happen on Ozempic, usually because of dehydration, lower intake of minerals from food, or changes in activity. They are not a typical direct side effect. Frequent, severe, or unusual cramps, or cramps with other symptoms, should be checked by your provider.<\/p>\n
A 2024 review of lean body mass changes with GLP-1 based therapies found that the proportion of total weight loss made up by lean tissue varied widely across studies. Eating enough protein and doing regular strength training helps protect muscle, which matters for strength and everyday function. Our guide on getting the most out of your GLP-1 treatment<\/a> covers why that matters.<\/p>\n Gently stretch the muscle, massage it, walk around, or apply warmth. For a calf cramp, flex your foot toward you while keeping your leg straight.<\/p>\n Seek care right away if a cramp comes with swelling, warmth, or redness in one leg, which can be a sign of a blood clot, or if you have severe muscle pain with weakness and very dark urine. Contact your provider if cramps are frequent, severe, or come with numbness, tingling, a racing or irregular heartbeat, or dizziness, since these can point to an electrolyte problem.<\/p>\n Vomiting or diarrhea can quickly lower your fluids and electrolytes. Use an oral rehydration drink and tell your provider if they last more than a day or two. If you are comparing medications, our guide on tirzepatide and semaglutide side effects<\/a> covers how they differ.<\/p>\n If cramps worry you, talk to your provider before stopping or skipping doses. They may want to check your electrolytes or review your other medicines. Our guide on taking a break and restarting<\/a> covers why stopping and restarting is more involved than it sounds. Our guide on the Ozempic starting dose<\/a> covers what the first weeks usually look like.<\/p>\n The prescribing information for Wegovy, which contains semaglutide, the same active ingredient as Ozempic, at a higher dose, notes that patients with diabetes mellitus taking it in combination with insulin or an insulin secretagogue, such as a sulfonylurea, may have an increased risk of hypoglycemia, including severe hypoglycemia. Shakiness or muscle twitching with sweating and confusion can be a sign of low blood sugar rather than a cramp. Check your blood sugar when this happens, and never change those medicines on your own.<\/p>\nWhat helps<\/h2>\n
