Published 03/29/2011 | 
Tadalafil is a PDEF5 inhibitor, manufactured in pill form under the brand name Cialis. The drug is manufactured by Eli Lilly and Company in a form of tablets, in 5 mg, 10 mg, and 20 mg doses. Cialis was approved by Food and Drug Administration in 2003 and prescribed for treating impotence or erectile dysfunction (ED).
Erectile dysfunction is a repeated inability to get and maintain an erection for long enough to have sex. It works by getting increased blood flow into the penis during sexual stimulation, and helps a male to achieve and maintain an erection. Cialis relaxes muscles and increases blood flow to particular areas of the body. The effect of the drug appears in 30 minutes after taking and lasts for about 36 hours. A man who takes Cialis for the first time need to observe the dose prescribed very carefully. An overdose of Cialis is possible if a person does not follow the prescribed dose and takes much of this drug.
An overdose can result in heartburn, headache, flushing, chest pain, and back pain, erection lasting more than 4 hours, indigestion, and some other symptoms. If such symptoms occur, a person should immediately consult the doctor.
You should consult your doctor about usage of Cialis, if you are taking any other drugs. Such drugs as imatinib, rifampin, dalfopristin, isoniazid, antifungal medications, antidepressants, diclofenac, conivaptan, heart or blood pressure medications, and any other prescriptions should not be taken along with Cialis.
Cialis can be taken with or without food. The drug can be used daily, but the dosage should be under serious control.
