What Can Help Me Manage Side Effects Immediately?
To help manage side effects while your body adapts, MedExpress recommends the following:
Adjust Your Portions
Eat smaller meals more frequently throughout the day rather than three large meals. Smaller portions are often easier to tolerate when using a GLP1.
Stay Hydrated
Drink plenty of fluids throughout the day, especially if you are experiencing vomiting or diarrhoea. Good hydration helps reduce the risk of dehydration while taking GLP1s.
Choose Bland Foods
Try to avoid greasy, rich, or highly processed foods, as these can worsen nausea. Simple, bland meals are often better tolerated during the early stages of GLP1 treatment.
When Might My Dose Be Adjusted?
If persistent side effects do not improve or begin to interfere with daily life, your treatment plan may need review. Depending on your circumstances, your
MedExpress prescriber may consider:
Extending your current dose: Remaining on the same dose for longer than the usual 4 weeks.
Lowering your dose: Temporarily reducing your dose to allow more time for adjustment.
Any dose changes are based on clinical assessment and tolerability.
When Should I Seek Further Review for GLP1 Side Effects?
Further review may be appropriate if:
Symptoms are severe or worsening.
Vomiting or diarrhoea is persistent.
Side effects are affecting your ability to eat or drink normally.
You feel unable to continue your current dose.
