Viagra Side Affects

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 an hour for the drug to work, but it will only help you if you are sexually aroused. 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. Viagra is usually taken once a day and works best about an hour prior to sex.

Most likely, your doctor will start you out on 25mg Viagra. This is the lowest dosage that most people can tolerate. It’s the lowest dose that has been proven effective in clinical studies. The lower dose may help reduce the risk of side effects, such as visual disturbances and a blue haze. It’s also a safer option if you have health conditions or take drugs that interact with Viagra.

Side effects

Viagra helps men relax blood vessels in the body. This can help heart conditions such as angina pectoris. Angina pectoris is a type chest pain caused by cardiovascular issues.

In some cases, Viagra can cause mild side effects such as headache or a runny or blocked nose. You may also 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. 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

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

You should also avoid drinking a lot of alcohol while taking Viagra. It can make some of the side effects worse, including flushing and headache.

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 can damage your penis and lead to 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.

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 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 decrease the effectiveness of the drug or cause side effects.
