What You Should Know About Viagra

Viagra (sildenafil) is an oral medication that treats erectile malfunction in men. It works by blocking some naturally occurring enzymes, which cause blood vessels to dilate. This improves blood flow to the penis.

It takes about an hour to take effect — but it only helps with an erection if you’re sexually aroused and stimulated. It must be taken on an unfilled stomach as a fatty food can slow down the drug’s absorbtion.

Dosage

There are many medications used to treat erectile dysfunction (ED), but Viagra is unique among them because it works only when you’re sexually aroused. The medication helps with the muscle movements needed to create and sustain an erection by increasing blood flow through the penis, or corpora cavernosa.

It starts working about an hour after you take the tablet, but it can take less time or longer depending on how much you eat and whether you’re eating fatty foods. You typically only take Viagra once a day, and it works best when taken about an hour before sex.

Your doctor will probably start you on 25mg of Viagra, which is the lowest dosage for most people. It’s also the lowest dosage that’s been proven to be effective in clinical trials. The lower dosage may reduce the risk of side-effects, such as visual disturbances or a blue haze. You can also choose this option if you suffer from health conditions or are taking drugs that interact negatively with Viagra.

Side effects

Viagra helps men relax blood vessels in the body. This can help with heart conditions like angina pectoris, a type of chest pain caused by cardiovascular problems.

In some cases, Viagra may cause mild side effects like headaches or a blocked or runny nose. It can also make you feel dizzy or lightheaded. If this happens, lie down or stay seated until you feel better.

If you have a history of Peyronie’s disease or blood cell disorders such as sickle cell or multiple myeloma, Viagra may not be right for you. It can be dangerous if your nitrate medication, such as nitroglycerin, is prescribed for chest pain or high pressure. The pill’s effectiveness can be affected by consuming a fatty food, and alcohol can reduce the duration of the effect. Talk to your doctor before you take this medication.

Precautions

Viagra can cause a sudden fall in blood pressure, which can make you feel nauseous or dizzy. This is more likely to happen if you combine Viagra with certain drugs that treat high blood pressure, enlarged prostate or alcohol. Talk to your doctor if you have these conditions before taking Viagra.

Avoid drinking alcohol when taking Viagra. Some side effects, such as flushing and headaches, can be made worse by alcohol.

You should not take Viagra if you have a heart condition or a history of stroke, or if you are taking nitrate drugs (such as nitroglycerin or isosorbide dinitrate/mononitrate, used to treat chest pain). Nitrates may block Viagra’s action. This medication can also cause a long-lasting and painful erection, called priapism. Priapism may damage your penis, resulting in permanent ED.

Other Drugs

A person’s ability to achieve an erection may be affected if they take Viagra for a prolonged period of time. This can lead to a psychological dependence on Viagra, and a desire for it to be taken even when there isn’t a sexual need. This can also cause relationship problems and distress.

Viagra should not be taken by people who have certain eye conditions such as non-arteritic anterior ischemic optic neuropathy (NAION) or hereditary retinitis pigmentosa because it can cause sudden loss of vision in one or both eyes. It should be used with caution by people who have low pressure, as it can cause blood pressure to drop to unsafe levels.

Other medications such as over-the-counter ibuprofen, alpha-blocker drugs such as Terazosin or doxazosin (used for high blood pressure treatment and benign prostatic hyperplasia), and alpha blocker medication like terazosin and the doxazosin can interact with Viagra. These interactions can lead to a decrease in the effectiveness of the medication or can cause side effects.
