Short answer: It’s possible — Ozempic (semaglutide) needs no dose change even for end-stage kidney disease, because it isn’t cleared by the kidneys. But the outcome evidence in dialysis patients is limited, and side effects like nausea, poor appetite, and low blood sugar need careful handling. This is a decision to make with your dialysis and kidney team, not on your own.
Why dosing doesn’t change. Semaglutide is broken down by the body’s normal protein-recycling, not filtered out by the kidneys. So being on dialysis does not cause it to build up, and the label does not call for a lower dose in advanced kidney disease.
Why it still needs care on dialysis. Even with unchanged dosing, several things matter more when you’re on dialysis:
- Appetite and nutrition. Ozempic reduces appetite. Dialysis patients are already at risk for muscle loss and undernutrition, so eating too little — especially too little protein — is a real concern. Weight loss goals have to be balanced against protecting muscle.
- Low blood sugar. If you also take insulin or a sulfonylurea, adding semaglutide can raise the risk of hypoglycemia; doses of those medicines may need adjusting.
- Nausea and fluid balance. Vomiting or diarrhea can upset the careful fluid and electrolyte balance that dialysis maintains.
- Limited outcome data. Major kidney trials (like FLOW) studied people with chronic kidney disease before dialysis, not those already on it. So while semaglutide is used in dialysis patients, we have less high-quality evidence about long-term benefits and risks in this exact group.
Reasons a team might still recommend it. Better blood sugar control, weight reduction to improve transplant candidacy, or heart-related benefits can all be good reasons — especially since obesity can be a barrier to getting listed for a kidney transplant.
Bottom line. Ozempic is not off-limits on dialysis, and the dose doesn’t change — but the decision belongs with your nephrology and dialysis team, who will weigh nutrition, blood sugar medicines, and your transplant goals.

Related questions
Does Ozempic get removed by dialysis? It isn’t cleared by the kidneys and isn’t dosed around dialysis sessions. Your team manages it based on how you tolerate it and your other medicines.
Can Ozempic help me qualify for a kidney transplant? Sometimes. Reaching a weight or BMI target can improve transplant candidacy, and weight-loss medication is one tool teams use. Ask your transplant center about their criteria.
Will Ozempic cause low blood sugar on dialysis? On its own it rarely causes severe lows, but combined with insulin or sulfonylureas the risk rises — those medicines may need to be reduced.
