PDE5 Inhibitor Hearing Risk: What You Need to Know

When you take a PDE5 inhibitor, a class of drugs used to treat erectile dysfunction by increasing blood flow. Also known as ED medications, they include popular brands like Cialis, Viagra, and Levitra. These drugs work by blocking an enzyme called phosphodiesterase type 5, which helps relax blood vessels. But for some people, this same mechanism might affect blood flow to the inner ear — and that’s where the risk comes in.

There’s real, documented evidence linking PDE5 inhibitors, specifically tadalafil and sildenafil. Also known as cialis and viagra, these drugs have been associated with sudden sensorineural hearing loss in rare cases. It’s not common — fewer than 1 in 100,000 users — but when it happens, it’s sudden. People report ringing in the ears, muffled hearing, or total hearing loss in one or both ears, often within hours of taking the pill. The FDA first flagged this in 2007, and since then, over 100 cases have been reported worldwide. The exact cause isn’t fully understood, but it’s likely tied to reduced blood flow or inflammation in the cochlea. If you’re on one of these meds and notice any change in your hearing, stop taking it and see a doctor immediately. Waiting even a day can reduce your chance of recovery.

Not everyone taking PDE5 inhibitors will face this risk. People with pre-existing conditions like high blood pressure, diabetes, or heart disease may be more vulnerable. Smoking and older age also increase the odds. But here’s the thing: if you’ve never had hearing issues before, and you’re otherwise healthy, your risk is extremely low. The benefits of these drugs for most men far outweigh the chance of this rare side effect. Still, it’s worth knowing the signs. You don’t need to avoid these medications — just be aware. Keep an eye on your hearing, especially after your first few doses. If something feels off, don’t brush it off as stress or earwax. Get it checked.
