Frequently Asked Questions

Common questions about switching GLP-1 medications.

Can I switch GLP-1 medications mid-titration?

In many cases, yes — but timing matters. Our calculator maps your current dose to the closest equivalent on the target medication and suggests the optimal titration entry point. Always confirm the plan with your prescriber.

Is switching from Ozempic to Foundayo safe?

Clinical data from the ATTAIN trials shows orforglipron (Foundayo) is well-tolerated. However, switching between different GLP-1 receptor agonist classes requires careful dose mapping. Our tool provides the clinical framework, but your doctor makes the final call.

Will I have a gap in coverage when switching?

Not necessarily. Our timeline tool shows you exactly when to start the new medication relative to your last dose of the current one. For most switches, there's either a direct transition or a brief washout period of 1-2 days.

How do costs compare between GLP-1 medications?

Costs vary dramatically — from $0 with manufacturer savings cards to over $1,500/month without insurance. Our cost comparison tool factors in your insurance status, available coupons, and pharmacy options to give you the real number.

What side effects should I expect when switching?

GI side effects (nausea, decreased appetite) are the most common and usually peak during the first 2-4 weeks of a new medication. Switching medications may re-trigger these effects even if they had resolved on your previous GLP-1.

Does MedSwitcher replace my doctor?

Absolutely not. MedSwitcher is an educational tool that helps you prepare for conversations with your healthcare provider. We provide clinical data and dose mapping — your doctor provides medical judgment for your specific situation.
