What Is Cialis ?

Cialis from Eli Lilly and Company is a medicine used to treat erectile dysfunction. It contains a drug named tadalafil.

As such, the dose is recommended to be 10 mg and it can be increased to 20 mg and reduced to 5 mg. This drug is to be taken only once daily.

Officially two dosage patterns have been suggested by the manufacturer; one is for daily use which is available in 2 doses, 2.5 and 5 mg, and the other is 36-hour dose. To decide which dosage pattern will be suitable for you, discussion with your doctor is of extreme importance. Read more about cheap cialis.

The common side effects of Cialis are headache and dizziness, which are caused by the drug’s tendency to lower the blood pressure. Flushing, stuffy and runny nose, pain in stomach, muscles and back, and indigestion are some other side effects. The pain in back and muscles starts within 12 to 24 hours when the drug is taken and generally is temporary. If it persists for more than two days, you should consult your doctor.

A rare side effect is prolonged erection. If this persists for more than 4 hours, then too you must consult your doctor. Read more about what does cialis do.

A rarer side effect is an abrupt loss of vision or hearing, with ringing sounds in the ears and giddiness. These side effects may occur with any ED tablet. It is not known till now if they are directly associated with the ED tablets or not, therefore if they occur, for the sake of safety, stop the ED tablets including Cialis and call your doctor immediately.

Consuming too much of alcohol is absolutely prohibited when you are taking tadalafil. Alcohol consumed with this medicine may give rise to headache, giddiness, raised palpitation and lowered blood pressure.

Some drugs too are not to be taken while you are taking tadalafil. Firstly, nitrates of any kind are prohibited. Examples of nitrates are ISMN, ISDN and nitroglycerine and they are prescribed for chest pain. Next, alpha blockers which are prescribed in prostate problems are not to be taken with this medicine. Any blood pressure medication too should not be taken along with this medicine. So also erythromycin, medicines taken to treat HIV, antifungal medication, and any other medicines treating erectile dysfunction are strictly prohibited to take along with the medicine.

Adcirca is another brand of tadalafil which is marketed for the treatment of pulmonary arterial hypertension. If you have been found to be allergic to Adcirca, you cannot take Cialis too because the underlying drug is the same.
