Cialis.

Cialis (tadalafil) is a prescription anti-impotence medicine classified as a PDA5 inhibitor that makes it possible for men suffering from erectile dysfunction to get stable erections when they need. Cialis is supposed to be taken 40-60 minutes before having sex and you can count on up to 36 hours of efficiency, although this period is different for different people. Serious side effects of Cialis are unlikely, but you doctor needs to know if you have erection that lasts longer than 4 hours, headache, chest pain, heartburn, pain in the back, flushing, stuffy or runny nose, or indigestion. It’s a lot more common for men using Cialis to experience milder side effects, such as diarrhea, back pain, muscle pain, sore throat, headache, upset stomach, warmth or redness in your face, neck, or chest, stuffy nose, and memory problems. There is no need to talk to your health care provider about them unless they start to bother you too much. Never take Cialis if you are also using certain alpha-blocker medications, recreational drugs, nitrates, or nitroprusside, as the combination is likely to cause sudden drop in blood pressure leading to fainting, stroke and even death. Never share Cialis with other people to whom it was not prescribed, as you may not know all the contraindications these people may have.
