  • Condition of arteries
  • Age
  • Sexual activity

Side Effects of Erectile Dysfunction Medications

Suppose you take Viagra for the first time. In that case, you may experience unwanted side effects ranging from headaches, upset stomach, and skin flushing.

For some men, side effects like ear ringing, hearing loss, vision changes, etc., are common. It is also essential to note that an irregular heartbeat is a possible side effect in some males.

Therefore, the recommendation is to ensure you consult a trained healthcare professional if you are at risk of a heart attack. Your doctor will suggest and explain in detail what you must do if you experience an irregular heartbeat or other specific side effects.

In addition, your doctor will advise on when oral ED medications might not be safe, like in the cases below;

  • When taking nitrate drugs
  • Severe liver disease
  • Hypotension or hypertension
  • Kidney disease requiring dialysis


ED is when a man has trouble keeping an erection firm enough for sexual activity. There is no doubt that oral medications like Viagra are often the first line of treatment for this condition.
