The Generic Prescription

Viagra is a prescription drug containing citrate salt of sildenafil and belongs to the selective inhibitor of cyclic guanosine monophospate (cGMP). Viagra works by relaxing muscles and increasing blood flow to particular areas of the body.

Viagra is prescribed to treat erectile dysfunction (ED).

Viagra comes in 3 dosages:
1. 25 mg tablet
2. 50 mg tablet
3. 100 mg tablet

Viagra must be taken exactly as it was prescribed for you. You cannot take it in a larger amount or for a longer period than was recommended by your doctor.

Viagra is usually taken 30 minutes to 1 hour before sexual activity though you may take it up to 4 hours before. However, you cannot take it more than once per day.

Viagra may be started on the lowest dose (25 mg) if you have kidney or liver problems, or you are 65 years old or older.

Viagra does not protect against sexually transmitted diseases, including HIV.

Viagra’s side effects are:
• Headache
• Facial flushing
• Upset stomach

Viagra is expensive but buying Viagra through online pharmacies can help. But not all Viagra sold on the net is genuine. You should be aware if the online pharmacy doesn’t ask for prescription and or is selling a so called generic Viagra that it could be potentially harmful.
