Vardenafil Side Effects: What You Need to Know Before Taking It

When you take vardenafil, a prescription medication used to treat erectile dysfunction by increasing blood flow to the penis. Also known as the active ingredient in Levitra, it works quickly and lasts several hours—but like all drugs, it comes with risks you can’t ignore. Many men use it without issues, but others experience side effects that range from mild headaches to serious heart problems. If you’re considering vardenafil or already taking it, knowing what to expect isn’t just helpful—it could save your life.

The most common side effects include flushing, stuffy nose, headache, and upset stomach. These usually fade after a few hours. But some reactions need immediate attention: sudden vision loss, ringing in the ears, chest pain, or an erection lasting more than four hours. These aren’t just inconveniences—they’re medical emergencies. If you’ve had a heart attack, stroke, or life-threatening heart rhythm problem in the last six months, vardenafil could be dangerous for you. It also interacts badly with nitrates (used for chest pain), alpha-blockers, and some HIV or antifungal drugs. Mixing vardenafil with these can drop your blood pressure to dangerous levels. Always tell your doctor about every medication you take, even over-the-counter ones.

Vardenafil doesn’t work the same for everyone. Age, liver or kidney disease, and even what you eat can change how your body handles it. High-fat meals can delay how fast it kicks in. Alcohol can make dizziness or low blood pressure worse. If you’re on blood pressure meds, you’ll need closer monitoring. People with sickle cell anemia, multiple myeloma, or leukemia are at higher risk for prolonged erections. And if you’ve ever had vision loss from a condition called non-arteritic anterior ischemic optic neuropathy (NAION), you should avoid vardenafil entirely.

It’s not just about the drug itself—it’s about your whole health picture.
