Viagra is used in the treatment of erectile dysfunction in men. The active ingredient in Viagra is sildenafil. Sildenafil is a PDE-5( phosphodiesterase type 5) inhibitors. PDE-5 inhibitors increase levels of a substance called cGMP(cyclic guanosine monophosphate). In erectile dysfunction there is a problem with levels of cGMP. Increasing levels of cGMP improves the blood flow to the penis allowing for a sustained erection. Viagra is not a substitute for sexually arousal. Sexual arousal triggers cGMP production. Viagra helps maintain levels of cGMP.

Viagra dosages

Viagra is available in dosages of 25, 50 and 100 mg. It takes from 30 minutes to 1 hour for the drug to work. It may take longer after a meal (high in fat/oil). Viagra is effective for up to six hours.

Side effects

Side-effects commonly reported include headaches, flushing, dizziness, indigestion, diarrhoea, back pain, muscle pain, rash, impaired vision.

People with serious health conditions should not be taking Viagra or should consult a doctor for advice. This includes heart disease, having had heart surgery, liver problems, kidney problems or undergoing kidney dialysis, recovering from a heart attack or stroke, stomach ulcers and high or low blood pressure.

Viagra may also interact with some medication and in some cases may cause a sudden drop in blood pressure which if left untreated could be serious. Examples of such medication include nitrates (poppers or prescription medicine), high blood pressure, epilepsy, hepatitis C, alpha-blockers, HIV/AIDS, tuberculosis, certain antibiotics (such as clarithromycin, erythromycin, telithromycin), anti-fungal treatment. Viagra should not be taken in conjunction with other drugs used to treat erectile dysfunction such as Cialis (tadalafil) and Levitra (Vardenafil).

The various doses of Viagra allow health practitioners to use a smaller dose in patients with pre-existing health conditions or with older patients (65 and over). In addition to a smaller dose the doctor may put a limit on how often Viagra can be taken.

Although initially available only by prescription, it is now possible to buy it online, over-the-counter at a pharmacy or as generic Viagra in Australia. Generic Viagra is also much cheaper than branded Viagra. A generic drug is one that contains the same active ingredient but may differ in strength and possible added ingredients to enhance the medication. Care must be taken when buying online as there is a huge market for counterfeit Viagra.
