What You Should Know About Viagra

Viagra (sildenafil citrate) is an oral medication used to treat erectile dysfunction in men. It works by blocking certain naturally occurring enzymes in the body, causing blood vessels to dilate and improve 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 also needs to be taken on an empty stomach, as a fatty meal can delay the drug’s absorption.

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

Besides helping men get and keep an erection, Viagra also helps blood vessels around the body to relax. This can help with heart conditions like angina pectoris, a type of chest pain caused by cardiovascular problems.

In some cases, Viagra can cause mild side effects such as headache or a runny or blocked 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 also be dangerous if you take nitrate medications such as nitroglycerin for chest pain or high blood pressure. Taking the pill with a fatty meal can affect how well it works, and consuming alcohol can decrease how long the effect lasts. Talk to your doctor before you take this medication.

Precautions

Taking Viagra can cause a sudden drop in blood pressure that can make you feel dizzy or faint. This is more likely if you take it with certain drugs used to treat high blood pressure or enlarged prostate, or with alcohol. Speak to your doctor before taking Viagra if you suffer from these conditions.

You should also avoid drinking a lot of alcohol while 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 cause a painful and long-lasting 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 may lead to a psychological dependency on Viagra and a desire to take it even when there is no sexual need. This can also cause relationship problems and distress.

People with certain eye conditions, such as non-arteritic posterior ischemic optic Neuropathy (NAION) and hereditary retinitis Pigmentosa, should not take Viagra because it can cause a sudden loss of sight in one or both of their eyes. It should also be used with caution in people who have low blood pressure because it can decrease blood pressure to an unsafe level.

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