Viagra is a medicine used to treat erectile dysfunction (ED) in men.
This is when a man cannot get, or keep, a hard erect penis suitable for sexual activity. When a man has erectile dysfunction, the nerves don’t communicate properly with his brain and blood doesnât flow properly into the corpus cavernosa. Taking Viagra relaxes the walls of your blood vessels and lets blood flow more easily into the parts of a man’s penis that cause an erection.
It is possible to get an erection for up to 4 hours after taking it.
However, usually the erection will only last a normal amount of time. Sexual stimulation is still needed because it doesnt cause erections on its own. It does not cure ED, increase a manâs sexual desire, or serve as a male form of birth control. Depending on how your body metabolizes it, you may be able to get an erection several times with Viagra in your body. Viagra probably won’t make you last longer in bed. No research has proven definitively that Viagra can increase how long you can have sex.
Men should not take Viagra any more than one tablet in 24 hours and it should not be taken with other ED medicines.
If you plan to use Viagra, you should take it an hour before planned sexual activity. The amount of time Viagra takes to start working varies from person to person, but it normally takes between half an hour and one hour. Viagra comes in 25mg, 50mg, and 100mg tablets. They are blue, rounded-diamond shaped, and are marked VGR on one side with PFIZER on the other. All strengths are available in a box of 4 tablets. The 100 mg tablets are also available in a box of 12 tablets.
The possibility of heart attacks is one reason why Viagra is a prescription drug rather than an over-the-counter drug like aspirin.
A doctor needs to understand your medical history and make sure that Viagra will not cause a heart attack. Also, another concern is headaches. The drug, as a side effect in some men, opens up arteries in the brain’s lining and causes excess pressure. Finally, the most well-known side-effect is an erection lasting much more longer than normal such as several hours. Other common side effects are: flushed skin, indigestion, abnormal vision, stuffy or runny nose, back pain, muscle pain, nausea, and dizziness.
Viagra is only available with a doctor’s prescription.
Your doctor will decide the correct dose for you depending on your condition and response. It can be one 25 mg tablet a day or one 50 mg tablet a day or one 100 mg tablet a day. Buying the branded version in South Africa is between 35 $ and 52 $ per pill for people with insurance according to Bloomberg. Pfizer sells a cheaper version of Viagra on their South African website: www.pfizerdirect.com.au This requires a valid prescription and cash only.
Generic versions of Viagra can be purchased online even without a prescription.
However, there is no way to be certain these pills actually contain the drug or are counterfeit. It is best to buy at a local pharmacy store or directly from Pfizer.
