What is Stendra?

Stendra (avanafil) is a prescription medication used to treat erectile dysfunction. Stendra works by relaxing smooth muscles in blood vessels, allowing for increased blood flow that when combined with sexual stimulation can help men achieve an erection. Stendra is effective for up to 6 hours.

Always follow your doctor’s instructions when taking Stendra. Never change dosage before consulting a healthcare professional.

• Stendra can be taken with or without food.
• Recommended starting dose is 100 mg, to be taken one hour prior to sexual activity.
• Your doctor may increase the dose to 200 mg or reduce it to 50 mg depending on its effect and any side effects you may experience.
• Do not take more than once per day. Allow at least 24 hours between doses.
• Stendra may remain effective for up to 6 hours.

Stendra is not a recreational drug, and does not enhance sexual performance in men who don’t experience erectile dysfunction.

Do not take Stendra if you also use:

• Nitrate drugs for chest pain or heart problems including nitroglycerin, isosorbide dinitrate, isosorbide mononitrate, or amyl nitrate “poppers”
• Riociguat for pulmonary arterial hypertension

Before prescribing Stendra, your doctor will perform a cardiac workup to ensure your heart is healthy enough to engage in sexual activity. Be sure to inform your doctor of your full medical history, especially:

• Heart disease, chest pain, or irregular heartbeat
• Heart attack, stroke or recent heart surgery
• Congestive heart failure
• HIV/AIDS
• High or low blood pressure
• Liver or kidney disease
• Vision loss or retinitis pigmentosa
• Bleeding disorders
• Stomach ulcers
• Peyronie’s disease
• Hearing disorders
• Blood cell disorders (sickle cell anemia, multiple myeloma, leukemia)
• An erection that lasted more than 4 hours
• Any health issue that makes sexual activity unsafe

Common side effects of Stendra include:

• Headache
• Flushing in the face and neck
• Back pain
• Stuffy or runny nose

Stop using Stendra and contact your doctor if you experience these more serious side effects:

• Feeling light-headed or fainting
• Symptoms of heart attack: chest pain, pain spreading to jaw or shoulder, nausea, sweating
• Erection that’s painful or lasts more than 4 hours
• Vision loss or sudden vision changes
• Hearing problems or ringing in ears
• Shortness of breath
• Pain, swelling, warmth, redness in legs

If you have nausea, chest pain, or dizziness during sex, seek immediate medical attention.

How long does Stendra last?

Stendra can be effective for up to 6 hours

How long does Stendra take to work?

Stendra usually takes effect within 30 minutes.

Is it safe to take Stendra with alcohol?

Drinking alcohol can actually contribute to erectile dysfunction, and may make Stendra less effective. Because both alcohol and Stendra can lower blood pressure, mixing the two increases the likelihood of side effects including dizziness and fainting.

How many times a day can I take Stendra?

Stendra should not be taken more than once daily. Ensure at least 24 hours have passed since your last dose.

Will Stendra affect my blood pressure?

Stendra can lower your blood pressure. Men who currently have low or high blood pressure should consult their doctor before taking Stendra. If you use nitrate drugs to treat chest pain, taking Stendra can cause a dangerous drop in blood pressure.
