Product description: Cialis is a brand new impotence treatment that helps men achieve erections faster. By expanding blood vessels and increasing blood flow to the penis, Cialis delivers quick results in as little as 30 minutes (30 minutes sooner than Viagra).

How to use this product: If you don't experience results the first time you take Cialis, your doctor may recommend increasing your dose to 20 mg. For most patients however, the normal startup dose is 10 mg at least 30 minutes before sexual activity. While taking Cialis, you should follow your doctor's advice exactly. DO NOT take more Cialis than what's prescribed to you. If side effects occur or if they become bothersome, talk to your doctor.

Side effects: Like all prescription medications, Cialis may produce some side effects. These side effects are generally mild to moderate in nature, and usually go away within a few hours of use. They include headache, dyspepsia, dizziness, flushing nasal congestion, back pain, and or muscle aches.

Precautions: Until you are certain how you are affected by Cialis, use caution when driving or operating heavy machinery. Cialis contains some lactose and should not be taken by patients who are lactose intolerant. Also, during treatment you should avoid grapefruit juice. Taking Cialis with grapefruit juice can increase your chances of experiencing undesirable side effects. If you are taking medications with nitrates or nitric oxide, have uncontrolled blood pressure (high or low), or if you have a history of stroke or heart attack DO NOT take Cialis.

Drug interactions: If you are currently taking medicines that contain nitrates, DO NOT take Cialis. Nitrates are used to treat chest pains in heart patients. Taking them with Cialis may cause your blood pressure to drop to unsafe levels.
