Who Should Not Take Cialis, Levitra, Staxyn, Stendra, or Viagra?

If you have suffered from a heart attack, stroke, or life threatening arrhythmia (irregular heart rate) within the last 6 months you should discuss other options with your doctor. It is also advised to avoid these drugs if you have uncontrolled high or low blood pressure or if you experience chest pain with sex.

What Are the Side Effects of Cialis, Levitra, Staxyn, Stendra, and Viagra?

Side effects are not common but they can occur. Side effects can include:

  • Headache
  • Upset stomach or heartburn
  • Flushing (feeling warm)
  • Nasal congestion
  • Changes in vision (color, glare)
  • Back pain (with Cialis)

Call your doctor if you experience severe forms of these symptoms or if they do not go away after 4-8 hours.

Warning

Call your doctor or seek emergency treatment immediately if you experience any of the following symptoms:

  • Rash
  • Painful erection
  • Prolonged erection (longer than 4 hours)
  • Fainting
  • Chest pain
  • Itching or burning during urination

Stop taking these medications and call a doctor or health care provider right away if you experience sudden or decreased vision loss in one or both eyes. A rare vision problem called NAION has been reported by a few men using these drugs. NAION (nonarteritic anterior ischemic optic neuropathy) causes a sudden loss of eyesight because blood flow is blocked to the optic nerve. People who have a higher chance for NAION include those who:

  • Are over 50 years old
  • Smoke
  • Have heart disease
  • Have diabetes
  • Have high blood pressure
  • Have high cholesterol
  • Have certain eye problems

How Should These Drugs Be Stored?

These drugs should be kept in its original container and out of reach of children. Store them away from excess heat and moisture (not in the bathroom). Discard any medication that has expired or is no longer needed.
