General English name: Avanafil
Application: Erectile dysfunction in men
Avanafil Drug Information
Medication Information: Erectile dysfunction (sometimes called impotence) means that you can not maintain a proper erection. There are several causes for this problem, one of which is narrowing of the arteries, which prevents blood from reaching the penis.
Avanafil works by blocking the action of a chemical in the body called type 5 phosphodiesterase. As a result, the blood vessels dilate and after sexual arousal, blood flow to the penis improves.
Avanafil is prescribed only for men with erectile dysfunction due to a specific disease, and you can buy Avanafil only with a prescription.
Contraindications to the use of Avanafil
Pay attention to the expiration date of the medicine and do not take it if the medicine in your hand has expired.
Never give the medicine to anyone else, even if you have the same symptoms.
Do not take more than the dose prescribed by your doctor, because you will have low blood sugar.
Check for drug interactions and be sure to tell your doctor what other medications you are taking.
