Directions

Cialis comes in 20 mg. The normal startup dose for most patients is at least 30 minutes before sexual activity. Remember to follow your doctor's advice exactly. DON'T take more Cialis than what's prescribed to you. If side effects occur or if they become bothersome, talk to your doctor.


Precautions
Cialis may cause dizziness in some patients. Until you're exactly sure how you'll respond to Cialis, use caution when driving or operating heavy machinery. To minimize your chances of experiencing side effects, avoid drinking grapefruit juice with Cialis. Also, DON'T use Cialis if you're taking medications containing nitrates, have uncontrolled blood pressure, or if you have a history of stroke or heart attack.


Possible side effects
Like most medications, Cialis might produce some side effects. In clinical testing the most common side effects reported with Cialis were headache, dyspepsia, dizziness, flushing, nasal congestion, back pain, and muscle pain. These side effects were generally mild and weren't severe enough to discontinue treatment.

Overdose
If overdose of Cialis is suspected, contact your local poison control center or emergency room immediately.


Additional information
Keep Cialis in a tightly closed container and out of reach of children. Store Cialis at room temperature and away from excess heat and moisture (not in the bathroom).
