Pharmacological management of persistent nausea with domperidone (preferred over metoclopramide) or other anti-emetics/prokinetics is an effective strategy for managing GLP-1 RA-induced nausea when dietary and titration strategies fail.
If diet changes aren't enough, ask your doctor about domperidone. It is often preferred over other anti-nausea drugs because it has fewer serious side effects. Use it as needed for nausea.
GoodSupportsHIGH confidence
Domperidone (10–20 mg three to four times daily, oral dosage, not in children <12 years) should be used rather than metoclopramide, especially in older patients, to minimize the risk of extrapyramidal side effects.

- Adhering to specific dietary modifications (smaller portions, low-fat, bland foods) and slow eating habits significantly reduces the frequency and severity of gastrointestinal adverse events (nausea, vomiting, diarrhea, constipation) in patients initiating GLP-1 receptor agonist therapy.Good
- Extending the dose-escalation period or temporarily suspending dose increases when gastrointestinal adverse events occur improves tolerability and treatment persistence without compromising long-term efficacy.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
