Vardenafil is a widely used medication most men can take without issues. However, like other prescription drugs, it can potentially interfere with other medications and substances. All PDE5 inhibitors, including vardenafil, shouldn’t be used with nitrites or other drugs prescribed to treat angina (chest pain) or heart failure. When combined with nitrates, vardenafil can cause a significant, sudden decrease in blood pressure that may be life-threatening. Low blood pressure (hypotension) can lead to heart problems like irregular heartbeat, heart rhythm changes, dizziness, heart attack, and potentially death.

Nitrate medications include nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Those used recreationally (called “poppers”) can also interact with the medication. Vardenafil can also interact with alpha-blockers, a type of medication used to treat hypertension and benign prostatic hyperplasia (BPH). The same goes for male-enhancement supplements with phosphodiesterase (PDE) inhibitors in the ingredients.

Overdose/Missed Dose

Headaches are by far the most common side effect of vardenafil and other oral medications used to treat ED. According to the FDA, around 15 percent of men who use vardenafil get one. Headaches typically fade away on their own as the drug exits your system. Since the medication has a moderate half-life, it’s rare for this side effect to last more than five hours. If you get severe headaches, it’s best to talk to your healthcare provider.

Who should not take Levitra?

They may suggest adjusting your dosage or using over-the-counter medication to reduce the severity of your headaches. Our guide to dealing with headaches from ED medications has more tips.

Erectile Dysfunction: Oral Therapy Treatment Options

You might notice that your cheeks, nose, chin, and forehead take on an inflamed, red appearance. Like other side effects, flushing typically improves over a few hours as the active ingredient exits your system. Irritation and inflammation inside the nostrils can also happen with vardenafil. Known medically as rhinitis, this side effect can result in a blocked airway or a runny nose. In clinical trials with vardenafil, nine percent of men who used the medication to treat ED developed symptoms of rhinitis.

What should I know about vardenafil before taking it?

This side effect may be more common with vardenafil than other ED treatments. For example, only two to four percent of men prescribed Cialis in clinical trials reported nasal congestion. About three percent of men who use vardenafil also report sinusitis, another form of nasal irritation and congestion. And general flu-like symptoms affect around three percent of users. Like the other common side effects of vardenafil, nasal congestion usually fades gradually as the medication leaves your body.

Vardenafil and other PDE5 inhibitors have been linked to hearing issues, including some cases of sudden hearing loss. In a report from 2010, researchers discussed a patient who experienced a sudden loss of hearing after using vardenafil to treat erectile dysfunction. This was only the second known case of hearing loss associated with vardenafil at the time the study came out — roughly seven years after the FDA (U.S. Food and Drug Administration) initially approved the medication. This makes hearing loss one of the rarest potential side effects of vardenafil.

Vardenafil Forms & Strengths

If you experience hearing loss (with or without tinnitus and dizziness) after taking vardenafil, seek immediate medical treatment. Vardenafil can cause several common side effects, most of which are mild and temporary: These side effects are similar to those of other ED medications. So switching to Viagra or Cialis may not be much better. Most men who use brand-name or generic vardenafil don’t have significant issues. In clinical trials, only 3.4 percent of participants stopped taking the medication due to side effects (compared to 1.1 percent for a placebo). Make sure you’re familiar with how to use vardenafil before taking it. Other medications for ED, such as Viagra (sildenafil), Cialis (tadalafil), and Stendra (avanafil), offer similar effects to vardenafil. Depending on your needs, you may get better results from one of these medications.

Several PDE5 inhibitor medications are linked to visual disturbances. These may include a noticeable color tinge to your eyesight, increased sensitivity to light, or blurred vision. Though visual disturbances are more common with other ED medications than with vardenafil, a small percentage of users report ocular side effects. In a small 2019 study, men who took a 40mg dose of vardenafil temporarily made more errors in a vision test (the Farnsworth–Munsell D100 color vision test) than those given a placebo. But 24 hours later, their vision was back to normal.

What Happens If I Miss a Dose of Vardenafil?

If you have noticeable or persistent visual disturbances while using vardenafil, contact your healthcare provider. Since vardenafil dilates blood vessels throughout the body, it can cause a temporary decrease in blood pressure. This drop is usually mild and won’t negatively affect your health if you don’t already have cardiovascular issues. If you have cardiovascular disease or currently take medication to treat high blood pressure (hypertension), using vardenafil could potentially lead to more serious health problems. You should also discuss any history of ulcers, leukemia, sickle cell anemia, or bleeding disorders with a healthcare professional before taking this medication. Grapefruit juice can impact how vardenafil is metabolized in the body, leading to higher blood levels of the drug and more side effects.
