Educational tool only. Always verify with your pharmacist or provider.
Severity-rated results
Color-coded HIGH, MODERATE, LOW, and NONE interaction levels.
About this interaction checker
This tool screens for known and theoretical interactions between common medications and GLP-1 receptor agonists or research peptides. It covers the most frequently prescribed drugs in categories like diabetes, cardiovascular, thyroid, and psychiatric medications.
GLP-1 interactions: The primary mechanism behind most GLP-1 drug interactions is delayed gastric emptying. Semaglutide and tirzepatide slow stomach emptying, which can affect the absorption rate and timing of oral medications taken concurrently.
Research peptides: Formal drug interaction studies for research peptides like BPC-157, TB-500, and CJC-1295/Ipamorelin are limited. The interactions shown are based on known mechanisms of action and theoretical pharmacological considerations.
Limitations: This tool does not account for individual patient factors such as kidney/liver function, age, weight, or specific dosing. It also does not cover all possible medications or supplement interactions.
