Can You Take Viagra with a Pacemaker?

Linda Girgis | MD

Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.

Yes, you can generally take Viagra with a pacemaker, but medical supervision is essential. Viagra (sildenafil) doesn't directly interfere with pacemaker function, but it can lower blood pressure by 8-10 mmHg on average. This blood pressure reduction could potentially affect your heart rhythm, especially if you have underlying cardiac conditions that required the pacemaker. The FDA requires careful monitoring for patients with cardiovascular devices taking PDE5 inhibitors like Viagra. Your cardiologist should evaluate your specific heart condition, pacemaker type, and current medications before approving Viagra use. Never start Viagra without consulting both your prescribing physician and the cardiologist managing your pacemaker.
