Last updated: January 2026
Quick Answer
GLP-1s may reduce absorption of oral contraceptives due to slowed gastric emptying. FDA recommends using a barrier method or switching to non-oral birth control. Ironically, GLP-1s can restore fertility in women with obesity-related PCOS — additional contraception is strongly advised.

Safety is the most important consideration when starting any medication. GLP-1 medications have been extensively studied in clinical trials involving tens of thousands of patients, and they have a well-established safety profile when prescribed and monitored by licensed healthcare providers.
What the Research Shows
The STEP and SURMOUNT clinical trial programs included over 25,000 participants combined. These large-scale studies established the efficacy and safety profile that led to FDA approval for weight management.
Staying Safe on GLP-1 Treatment
- Only obtain GLP-1 medications through licensed healthcare providers and pharmacies
- Follow your prescribed dosing schedule and titration plan
- Report any unusual symptoms to your provider promptly
- Attend regular follow-up appointments for monitoring
- Inform all your healthcare providers that you take GLP-1 medications
- Keep medications stored properly and check expiration dates
