5 Common Side Effects of Erectile Dysfunction Medication

Why Does ED Medication Have Side Effects?

Sildenafil (the active ingredient in Viagra) was originally developed as a blood pressure medication before it was ever used to treat ED. In fact, erections were just a “side effect” of the original hypertension medication. That’s why Viagra can cause dangerously low blood pressure, especially if you’re already taking high blood pressure medication. Tell your doctor if you’re taking medications like nitrates or recreational “poppers” that can lower blood pressure to avoid dangerous side effects and interactions.

Severe Side Effects of ED Medication

Go to the emergency room immediately if you experience any of the following symptoms or side effects:

  • Chest pain
  • Shortness of breath
  • Severe headaches
  • Fainting
  • Erections that last longer than 4 hours
  • Visual changes (like loss of sight)
  • or anything out of the ordinary—even lightheadedness

If you notice any severe or prolonged symptoms, contact a doctor immediately. It doesn’t matter how rare a side effect is if you’re the one experiencing it.

Each ED medication has its own unique drug interactions and side effects that you should be aware of when choosing the right treatment. Read the IMPORTANT SAFETY INFORMATION for Viagra, Cialis, and Levitra for more information about risks, including potential drug interactions. Talk to your doctor to choose the best treatment based on your medical history, symptoms, and preferences.
