Common side effects
Nausea, vomiting, diarrhea, constipation, stomach pain, headache, and fatigue. These are not all of the possible side effects.
Compounded medication: not FDA-approved
The semaglutide and tirzepatide offered through Ryo are compounded preparations prepared by a licensed pharmacy. Compounded drugs are not FDA-approved. The FDA does not review compounded drugs for safety, effectiveness, or quality before they are marketed. [Counsel and pharmacy to state and maintain the legal basis for compounding (503A patient-specific or 503B outsourcing facility) and keep it current as shortage listings change.]
Reporting side effects
Contact your provider about any side effect. For a medical emergency or suspected overdose, call 911 or your poison control center. You may also report side effects to the FDA at MedWatch (1-800-FDA-1088).
