How to buy Viagra?
When a man has difficulty getting or keeping an erection, he is said to have erectile dysfunction. Also known as ED, erectile dysfunction is a common problem that can happen to any man. All over the world, men with ED have found that using Viagra is the solution to their ED. Viagra is the top-selling drug worldwide for the treatment of ED. Viagra is made by Pfizer Inc.
The generic name of the active ingredient in Viagra is sildenafil. Other drug companies worldwide make their own sildenafil products. Some go by the generic name of sildenafil, and others have their own brand name, such as Kamagra made by Ajanta Pharma, Silagra made by Cipra, Edegra made by Sun Pharmaceutical, and several others. All of these products contain the identical active ingredient, sildenafil.
How does Viagra work?
An erection happens when sexual stimulation causes an increase in blood flow into the penis. If this blood flow into the penis is reduced, it is more difficult to get an erection. There are smooth muscles that wrap around these blood vessels, and if the muscles contract, they cause the blood vessels to become narrower. Narrower blood vessels means less blood can flow into the penis.
Viagra works by blocking the natural chemicals that cause the smooth muscles around blood vessels to contract. This leads to the relaxation of the muscles, and the blood vessels become wider and allow more blood to flow into the penis. The natural chemical that results in smooth muscle contraction is called phosphodiesterase-5 enzyme, or PDE5. Viagra is thus called a PDE5 inhibitor.
Viagra can help to both get an erection and keep the erection going. It is important to be aware, however, that Viagra does not cause an erection on its own. Sexual stimulation is still required for the erection to begin.
What is Viagra used for?
Viagra is approved by the FDA to treat erectile dysfunction. It is also approved to treat a condition known as pulmonary arterial hypertension (PAH), or high blood pressure in the lungs. Pfizer makes a separate sildenafil product for treatment of PAH, called Revatio. Revatio improves blood flow in the lungs. Revatio comes in a lower strength than Viagra.
Viagra products have also gained an off-label use in the world of bodybuilding. The Viagra is taken simultaneously with anabolic steroids. Bodybuilders claim the Viagra helps their performance by delivering the steroids and other supplements to their muscles faster, and leads to better performance in the gym. This is thought to happen because Viagra also helps increase blood flow to other parts of the body, including muscles.
How do I take Viagra?
Viagra comes in the form of blue, diamond-shaped, film-coated oral tablets. It comes in strengths of 25 mg, 50 mg, and 100 mg. Generic sildenafil, and other brands, may be blue or white, and may have an oval or round shape. In addition to the standard pill form, generic sildenafil and other brands also are available in soft gel form and chewable form. These newer forms have names like Viagra Super Active and Viagra Professional.
The usual starting dose of Viagra is 50 mg. The dose should be taken one hour before desired sexual activity, but it can be taken anywhere from 30 minutes to 4 hours ahead of time. Soft gel and chewable forms may work in as little as 15 minutes. Only one dose of Viagra should be taken daily.
Who can take Viagra?
Certain health conditions can make it unsafe to use Viagra without medical supervision. Men with heart disease or heart failure, liver disease or kidney disease, should check with their doctor before taking Viagra. Other conditions where medical supervision is recommended include bleeding disorders, active peptic ulcer disease, and retinitis pigmentosa. The best way to be sure you use Viagra safely is to check with your doctor first.
What side effects does Viagra have?
Viagra has some common side effects, including headache, nausea, nasal congestion, flushing, sore muscles, and low back pain. These side effects are related to the increased blood flow in the body, and usually resolve after a few hours. In rare cases, Viagra can cause blue-tinted vision, or blurry vision. If side effects are a problem for you, your doctor may adjust your dose.
Some rare but serious side effects of Viagra are priapism, and sudden loss of hearing or vision. Priapism is a condition where the erection lasts too long. If your erection lasts for four hours or longer, you should get medical help right away. An erection that lasts too long can cause permanent damage to the tissues of the penis and may even lead to impotence. If you have a sudden loss of hearing or vision, get medical help immediately.
Does Viagra have any interactions with food, other drugs, or herbal supplements?
There are certain medications that should never be used at the same time as Viagra. Do not use more than one kind of Viagra at the same time, or other PDE5 inhibitors such as Levitra and Cialis. Combining PDE5 inhibitors can lead to dangerously low blood pressure, and can even be fatal.
Do not use Viagra if you need to take a drug in the nitrate class. These include drugs taken for heart disease like nitroglycerin, isosorbide mononitrate, and isosorbide dinitrate. There is also a street drug in this group, amyl nitrite, which goes by the name “Poppers”. Do not take Viagra if you use Adempas (riociguat) for pulmonary hypertension. Combining these drugs can also lead to an unsafe drop in blood pressure.
Other drugs that can interact with Viagra include cimetidine, some antibiotics, some HIV medications, heart medications, blood pressure medications, and antidepressant medications. This is not a full list, so the best course of action, if you take a prescription drug, is to check with your doctor before using Viagra.
Viagra can also interact with grapefruits and grapefruit juice. Do not eat grapefruit products on the same day as Viagra. Viagra can also interact with some herbal supplements such as St. John’s Wort. Be sure to tell your doctor about every nutritional or herbal supplement you may take.
Viagra in South Africa
In South Africa, the manufacturing, distribution, sale, and marketing of drugs is under the authority of the new South Africa Health Products Regulatory Authority, or SAPHRA. Currently there is a transition going on from the former Medicines Control Council (MCC) to the new agency.
SAPHRA categorizes drugs into different groups based on their different properties, such as safety, toxicity, the illness or condition the drug treats, the need for a doctor’s diagnosis, the potential for dependency and abuse, and the patient’s need for the medicine. SAPHRA has created eight different groups of drugs, starting with Schedule 0 drugs (S0) and ending with Schedule 8 (S8) drugs.
The drugs that are considered safest are S0, and these can be sold even in grocery stores. Examples of drugs that are S0 include aspirin, paracetamol, and vitamins. A prescription is required for medications that are S3 and higher. Viagra products and other PDE5 inhibitors are all in the S4 group, and need a prescription.
It is easy to locate an online source for Viagra that will sell it without a prescription to men living in South Africa. One example of such a site is https://www.viagrastoresa.com/buy-viagra-south-africa.html. Online ordering has a number of advantages, including greater privacy, lower costs, and discreet shipping directly to your home.
There are some risks involved in online ordering that you should be aware of. Pfizer has done research into internet sources of Viagra, generic sildenafil, and other brands of sildenafil. Some sildenafil products have been found to have too much of the active ingredient, or even none of the active ingredient.
