Safety and Side Effects
Information on Safety and Side Effects of Sildenafil
The side effects of Sildenafil are similar to what most men might expect from an ED medication.
Though the benefits of using sildenafil as a treatment for erectile dysfunction are well documented (4 out of 5 men report being able to achieve and maintain an erection firm enough for sex), no medication comes without possible side effects.
MediSuite urges all patients to speak to their doctor first about their erectile dysfunction and the side effects of sildenafil before beginning treatment.
What are the Possible Side Effects of Taking Sildenafil?
Possible side effects may include the following:
- Erections that last longer than 4 hours. “Priapism” is a condition where an erection will not go away. If your erection lasts more than 4 hours, seek medical attention right away. If left untreated, priapism can cause permanent damage to the penis.
- Sudden loss of vision. Sudden loss of vision can be a sign of a serious problem called nonarteritic anterior ischemic optic neuropathy (NAION). Call your physician right away if you experience vision loss after taking sildenafil.
- Sudden loss of hearing. Although uncommon, some patients may experience a ringing in their ears or feeling of dizziness. Call your physician right away if you experience hearing loss after taking sildenafil.
Other common mild side effects include:
- Muscle aches and pains
- Bloody nose
- Difficulty breathing
If you experience any side effects, talk to your doctor. They may adjust your dosage or suggest lifestyle changes that make the medication work more effectively.

- Ritonavir (Norvir®) or other medicines used to treat HIV infection
- Ketoconazole (Nizoral®)
