Cialis.

Cialis (tadalafil) is a phosphodiesterase (PDE) inhibitor specially intended for the treatment of male impotence – inability to get and maintain an erection for long enough to have sex. Mild side effects are normal, especially at the beginning of the treatment and may include stuffy nose, sore throat, upset stomach, headache, memory problems, diarrhea, warmth or redness in your face, or muscle pain. More serious side effects are unlikely but you still need to know about the possibility of getting them. The following ones are sometimes reported: dizziness, rash, loss of hearing, changes in color vision, chest pain, priapism, ringing in ears, blurred vision, and hives. You will need to take Cialis an hour before having sex and expect up to 36 hors of efficiency. This medicine is supposed to be taken on an empty stomach, although having a small meal is unlikely to affect the success of your treatment in any way. Never combine Cialis with nitrate-based medications, such as isosorbide dinitrate, amyl nitrate, isosorbide mononitrate, nitroglycerin, or butyl nitrate, as dangerous interactions are possible leading to a sudden drop in blood pressure.
