Viagra is considered to be a ‘wonder drug’ by some, especially for older men suffering from erectile dysfunction. Originally, Viagra was being researched as a drug to help control hypertension and other heart related conditions, including angina pectoris, at the Pfizer UK research facility. While it was discovered to have little effect on heart conditions, researchers quickly realized that the drug had a significant effect on penile erections. Generically known as Sildenafil, Viagra was first patented by Pfizer in 1996 and approved by the FDS in the United States in 1998. Nine months after the FDA approved its use for erectile dysfunction in the US, South Africa followed suit as it was approved for use literally ‘down under.’
While this drug is intended to be used by males only, there has been some recent interest to hold clinical studies to detect the possible effect on women. Particularly, does Viagra increase the volume of blood to the female sex organs to stimulate the female libido. “Female Viagra” is not Sildenafil, but an entirely different type or pharmaceutical that is still currently being studied and evaluated. The drug is called Flibanserin and was recently evaluated and approved for use in the US by the Food and Drug Administration.
Viagra comes in 25mg, 50mg, and 100 mg doses, typically packages in four tablet strip package and costs the patient around $6.20, regardless of the dosage. There is a very lucrative counterfeit trade for the drug, so any package containing a pill count other than four is a not the legitimate product. When taken by mouth, the average time to the onset of an erection is just under 30 minutes, with the effects usually lasting a couple of hours, depending on the dosage.
Typical side effects of Viagra include headache, flushing, indigestion, nasal congestion, and impaired vision. Some users have reported erections lasting more than four hours, and medical attention should be sought if such a condition occurs. In the most rare cases, users may experience severe low blood pressure, myocardial infarction (heart attack), ventricular arrhythmias, stroke, increased intraocular pressure, and sudden hearing loss.
In addition, users need to beware of potential interactions with other medication they may be taking for other medical conditions.Care should be exercised by people who are also taking protease inhibitors for the treatment of HIV infection. Protease inhibitors taken the same time can severely increase the intensity of any possible adverse side effects. Other drugs that interfere with the metabolism of sildenafil include erythromycin and cimetidine, both of which can also lead to prolonged plasma half-life levels. Cimetidine is also known and sold as Tagamet.
It my take a few discussions with primary care doctor to get the proper dosage established. Many user reviews have stated that certain levels of Sildenafil have little to no effect if the correct dosage is off.
There are generic versions available, which are typically less expensive. In general, it is slightly more expensive to purchase Viagra online within South Africa and also represents the greatest risk of buying pills.
