When To Use Viagra

What You Should Know About Viagra

Viagra (sildenafil citrate) is an oral medication used to treat erectile dysfunction 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 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 dose may help reduce the risk of side effects, such as visual disturbances and 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 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, you can either lie down or remain seated until your symptoms improve.

Viagra may not be safe for you if you have certain health problems, such as blood cell disorders (such as sickle cell anemia or multiple myeloma), or a history of Peyronie’s disease. 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.

Avoid drinking alcohol when 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 cause a painful and long-lasting erection called priapism. Priapism may damage your penis, resulting in permanent ED.

Other Drugs

If a person takes Viagra for a long period of time, it may affect their ability to induce an erection naturally. 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 lead to relational 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 decrease the effectiveness of the drug or cause side effects.
