Overview Information on Cialis
Pharmacist Tip
Store Cialis at room temperature, away from excess heat, light, or moisture.     
Cialis® is the brand name of the medicine tadalafil, which is used to treat erectile dysfunction (ED) in men. ED is a condition in which a man is unable to get or maintain an erection. Cialis is in a class of medicines called phosphodiesterase (PDE) inhibitors.

Doctors also prescribe Cialis to treat symptoms related to an enlarged prostate, which is a medical condition called benign prostatic hyperplasia (BPH). Men who have enlarged prostates may have problems urinating and emptying their bladders. When men have both ED and BPH, Cialis can be taken to treat both conditions.

If you have ED, Cialis can help erection problems by increasing the blood flow to your penis when it is stimulated sexually. If you have BPH, Cialis will improve your urine flow and reduce BPH symptoms. Cialis does not cure either ED or BPH.

Cialis comes in a tablet form. If you are taking Cialis as needed, you should not take it more than once during any 24-hour period. Take your dose at about the same time each day. Make sure that you take Cialis exactly as your doctor tells you to.

Before you start taking Cialis, be certain to tell your doctor if you have any allergies to medicines. Give your doctor a complete list of any medicines you are taking so they can check for any you should not take with Cialis. Include any over-the-counter medicines or supplements you are taking, in particular St. John's wort.

Be sure to tell your doctor if you are taking a medicine that contains nitrates. This includes “poppers” or any illegal or street drugs that may contain nitrates. Taking nitrates when you are taking Cialis can cause a very serious drop in your blood pressure that is not safe.

In addition, before prescribing Cialis for you, your doctor needs to know if you have had eye or vision problems, including a rare disease called retinitis pigmentosa. It is important to tell your doctor if you have heart disease, chest pain, or any heart problems. Not everyone should take Cialis, so it is important to tell your doctor about all your medical conditions before you take Cialis. Women should not take Cialis.

Some patients taking Cialis have reported side effects such as headaches, stomach symptoms (such as heartburn, nausea, and diarrhea), back pain, muscle aches, flushing, and stuffy or runny nose. These side effects are the most common.

Contact your doctor right away if you experience any of the following symptoms while taking Cialis:
  • Sudden vision or hearing problems or changes
  • An erection that lasts more than four hours
  • Dizziness or chest pain
  • Hives, a rash, difficulty swallowing or breathing, or swelling of your head, neck, hands, feet, ankles, or lower legs
  • Skin that is peeling or blistering
