Yes—report Wegovy (semaglutide) side effects to your doctor, especially if they’re new, worsening, or affecting daily life
If you’re taking Wegovy and you notice side effects, it’s generally a good idea to let your prescribing doctor know. Many side effects are expected, but your doctor can help you figure out whether the symptoms are part of normal adjustment, a medication side effect that needs management, or a sign of something more serious that needs prompt care.
Which side effects are most urgent to report?
Report side effects promptly (and seek urgent care/emergency help if severe) if you have symptoms that could indicate a serious problem. Key examples to take seriously include:
- Signs of an allergic reaction (for example, swelling of the face or throat, trouble breathing, or widespread rash).
- Severe or persistent vomiting or dehydration (for example, dizziness, very dark urine, inability to keep fluids down).
- Severe abdominal pain (especially if it doesn’t improve), which could signal a serious gastrointestinal issue.
- Symptoms that could suggest gallbladder problems (such as pain in the upper right abdomen, fever, or yellowing of the skin/eyes).
- Any symptoms of pancreatitis (for example, significant persistent upper abdominal pain, often with vomiting).
If any symptoms are severe or you’re worried, contacting your doctor right away is appropriate.
If the side effects are mild, do you still need to contact them?
Yes. Even mild side effects can be worth reporting because Wegovy doses are typically increased gradually, and your doctor may adjust titration, timing with meals, or supportive care. Common side effects such as nausea, vomiting, diarrhea, constipation, or heartburn are often manageable, but your prescriber should still know if symptoms:
- keep recurring,
- stop you from eating/drinking normally,
- interfere with work or sleep,
- worsen after dose increases.
What should you tell your doctor so they can advise you?
When you contact your doctor, include:
- The side effect(s) you’re having and when they started (and whether they began after a dose change).
- How severe they are (mild/moderate/severe) and whether they’re getting better or worse.
- How often they happen.
- Any actions you’ve tried (diet changes, anti-nausea meds, hydration, timing of injections).
- Your current Wegovy dose and injection schedule.
- Any other medications you’re taking and any relevant medical conditions.
Should you stop Wegovy on your own if you’re having side effects?
Don’t change or stop Wegovy without medical advice. Abruptly stopping may not address the underlying issue, and restarting later can require a careful plan. Your doctor can decide whether you need to pause the dose, slow titration, or switch strategies based on the specific symptoms and your risk factors.
What if the side effect feels like it’s “just nausea”?
Even “just nausea” matters because it can lead to dehydration or poor intake. If nausea is frequent enough that you cannot keep fluids down, or you’re losing weight rapidly beyond what your clinician advised, report it. Your doctor may help with dose timing, eating habits, and symptom management.
Can you report side effects outside your doctor?
Yes. In addition to contacting your doctor, you can report suspected medication side effects through official vaccine/drug safety reporting channels in your country (for example, the FDA MedWatch program in the U.S.). Your doctor can also file reports if needed.
If you want, tell me what you’re experiencing
If you share the side effects you’re having (what they are, how severe, when they started, and your current Wegovy dose), I can help you judge whether it sounds like something to report urgently versus soon—and what details to include when you call.
