Wegovy dosage summary
Wegovy is started at a low dose and increased gradually every four weeks. This titration approach allows your body to adjust to the medication and significantly reduces the risk and severity of side effects, particularly nausea.
You should never increase your dose faster than the schedule below. If you experience side effects that are difficult to manage, you can stay at your current dose for longer before moving up. Speak to our Phlo Clinic Patient Care Team for guidance.

How does Wegovy work?
Turn down the food noise
It works for weight loss by binding to the GLP-1 receptor, mimicking the action of GLP-1 in the body. This helps to regulate feelings of fullness in the brain and slows gastric emptying and digestion in the stomach.

Can you switch from Mounjaro to Wegovy?
Yes, you can. Transitioning from Mounjaro to Wegovy can be safe and manageable with the right guidance.
Both Mounjaro and Wegovy are clinically proven GLP-1 weight loss injections, and switching between them is more common than many people realise. There are several legitimate reasons to make the move.
Common reasons people switch from Mounjaro to Wegovy:
Cost: Wegovy can be more cost effective compared to Mounjaro, making it a more affordable option for long-term treatment
Side effects: Some patients find tirzepatide (Mounjaro) causes more pronounced gastrointestinal side effects and tolerate semaglutide (Wegovy) better
Cardiovascular health: Wegovy has a specific MHRA approval for reducing the risk of heart attack and stroke in adults with established heart disease, which may make it the clinically preferred choice for some patients
Personal preference: The FlexTouch pen format suits some patients better than the KwikPen
Both medications work by mimicking GLP-1, a gut hormone that reduces appetite and slows gastric emptying. Mounjaro additionally mimics GIP (a second hormone), which is thought to enhance appetite suppression. Switching from Mounjaro to Wegovy does not mean starting from scratch; our clinical team will recommend an equivalent Wegovy dose based on where you are in your Mounjaro treatment.

What Wegovy dose should I start on when switching from Mounjaro?
You will not need to restart at the lowest 0.25mg dose. Your Wegovy starting dose is matched to your current Mounjaro dose, though your exact dose will be confirmed during your clinical consultation.
Like all medications, Wegovy can cause side effects. Most are mild to moderate, tend to occur when first starting treatment or after a dose increase, and improve as your body adjusts. The gradual dose escalation schedule is specifically designed to minimise their impact.
