What are the side effects of Viagra?

Viagra is used in the treatment of erectile dysfunction to help you get and maintain an erection during sex. There are some potential side effects that you may get when you take Viagra.

Viagra contains the active ingredient sildenafil citrate. Sildenafil is a phosphodiesterase type-5 (PDE5) inhibitor and works by increasing the blood flow to your penis. As Viagra works on blood vessels it can affect other parts of your body and cause side effects.

The majority of these side effects will go away within a few minutes to a few hours after taking Viagra. You can also follow a few simple steps to make sure you reduce your chance of getting side effects.

Viagra is manufactured by Pfizer and is the brand name for sildenafil tablets. You can request Viagra or other erectile dysfunction treatments from Asda Online Doctor by ZAVA.

What are the side effects of Viagra?

Viagra has several possible side effects. Some are more common than others, which means you’re more likely to experience these side effects. If you do experience any common side effects, these will pass within a few hours and are generally not harmful.

Rare side effects of Viagra can be more serious. If you experience any rare side effects, contact your doctor or hospital emergency department immediately.

Remember that these side effects do not tell you how strongly you might feel these symptoms. For example, you may feel only slightly dizzy after taking Viagra, whereas someone else might feel that they cannot stand up properly. Side effects may affect you differently compared to other people.

Common side effects of Viagra

Common side effects of Viagra can affect up to 1 in 10 people, and they include:

  • feeling dizzy
  • feeling sick
  • indigestion
  • blurred vision
  • hot flush (suddenly feeling hot, especially in your face or the top half of your body)
  • a stuffy nose

Uncommon side effects of Viagra

Uncommon side effects of Viagra are less likely to happen to you as they can affect up to 1 in 100 people. These uncommon side effects include:

  • being sick
  • visual disturbances (flashes of light or increased sensitivity to light)
  • pain or irritation in your eye
  • skin rash
  • fast or pounding heartbeat
  • dry mouth
  • high blood pressure or low blood pressure
  • blood in your pee
  • nosebleeds
  • muscle pain

Rare side effects of Viagra

Rare side effects of Viagra will only affect up to 1 in 1,000 people. This means for every 1,000 people that take Viagra, only 1 or 2 will experience these rare side effects, so it’s unlikely that it’ll be you.

Rare side effects are more serious than common side effects and will need medical attention from a doctor.

Rare side effects of Viagra include:

  • fainting
  • stroke or heart attack
  • an irregular heartbeat
  • bleeding from your penis
  • blood in your semen
  • loss of hearing
  • significant vision changes, such as reduced vision, double vision or seeing halos around lights
  • an erection that does not go away after 4 hours or is painful. This is called priapism.

If you notice any of these side effects after taking Viagra, call 999 immediately.

You can find more information about these side effects in the Viagra patient information leaflet.

How long do the side effects of Viagra typically last?

The length of time the side effects of Viagra typically lasts depends on the specific side effect you experience. You might be wondering how to get rid of the side effects of Viagra, and most of the time you have to wait for the medicine to be broken down by your body.

Once you have taken a Viagra tablet, the active ingredient sildenafil is absorbed into your bloodstream within 30 minutes to 1 hour. If you are sexually aroused within this time, you’ll be able to get and maintain an erection for sex.

Sildenafil remains in your body for around 4 hours. After this time your body will get rid of the drug. If you experience any side effects after taking Viagra it can take around 4 hours or less before you feel better.

If you have any side effects after taking Viagra that do not disappear or improve after 4 hours, speak to your doctor. Do not take more than 1 Viagra tablet within 24 hours.

Are there any long term side effects of taking Viagra?

The side effects of Viagra are not long term effects as they normally improve after a few hours. Some serious side effects can cause long term problems if you do not get them treated immediately. These include:

  • prolonged erection or a painful erection that lasts more than 4 hours with or without sexual activity (also known as priapism)
  • a serious allergic reaction (difficulty breathing, swelling of the face or throat)
  • chest pain
  • serious skin reactions, such as peeling or blistering of the skin
  • seizures
  • a sudden loss of vision that may cause damage to the optic nerve

If you experience chest pain after taking Viagra, do not use nitrates to treat the chest pain (like GTN or nitroglycerin spray). Using nitrates with Viagra can cause a sudden decrease in your blood pressure. Instead, you should call 999 immediately.

Remember that the above side effects are rare, so you are not likely to experience them.

If left untreated, these side effects can cause long term damage to your health. It’s better to get your symptoms checked out than to leave them alone or wait for an improvement. If you are at all concerned about a serious side effect you’re experiencing, seek urgent medical advice.

How to reduce the side effects of Viagra

You can reduce the side effects of Viagra by following a few simple steps. Remember that it’s not always possible to avoid all side effects as you may be more sensitive to Viagra than other people. By taking Viagra with the guidance of a doctor and avoiding certain foods or drinks you can reduce the possible range of side effects.

Take Viagra as directed

You should take Viagra as you have been directed by your doctor. The normal dose of Viagra is to take 1 tablet around an hour before you have sex. Viagra needs sexual stimulation to work properly and help you get an erection, so you have to be aroused for it to work.

If side effects persist even after you have followed the advice of your doctor or pharmacist, you may need to change how much Viagra you take. Your doctor can advise you on a dose change.

Viagra is available as 25mg tablets, 50mg tablets and 100mg tablets. Your doctor will usually prescribe 50mg Viagra tablets as a starting dose. If you experience side effects with Viagra 50mg tablets, speak to your doctor to find out if Viagra 25mg tablets might be a better option for you.

A lower strength of Viagra may be more suitable for you if you have certain medical conditions, such as liver or kidney disease or if you are taking certain medications.. You can request sildenafil 25mg tablets from Asda Online Doctor.

You may find other alternatives to Viagra that are more suitable for you and have fewer side effects. These include other PDE5 inhibitors such as:

  • Levitra, the brand name for vardenafil
  • Cialis, also known as tadalafil
  • Spedra, also known as avanafil

You can also consider Vitaros cream as an alternative treatment for erectile dysfunction.

Some prescription drugs can interact with Viagra and cause stronger side effects, these include:

  • alpha-blockers, like doxazosin to treat high blood pressure (hypertension)
  • treatment for HIV, like ritonavir
  • riociguat

Other medications that contain amyl nitrate (also known as poppers) can cause a sudden drop in blood pressure, so you should not use them with Viagra.

Tell your doctor or pharmacist if you are taking any regular medication, over the counter medicines or supplements. They can discuss with you whether Viagra is the t for you.

Avoid grapefruits and grapefruit juice

When you take Viagra, avoid eating grapefruits and drinking grapefruit juice. There is a chemical inside grapefruits that interacts with Viagra and can affect how sildenafil breaks down in your body.

Your liver contains enzymes that break down drugs to make sure the medication does not stay in your body for a long time. One of these enzymes is called CYP3A4. A chemical in grapefruit blocks this enzyme which can change how long sildenafil stays in your body.

This means the effects of sildenafil in your body are not predictable after you’ve had a grapefruit or grapefruit juice. You may experience stronger side effects or find it difficult to get an erection. Grapefruit can also affect some blood pressure medications, such as felodipine.

If you’re keen on having a healthy fruit juice, try a glass of fresh orange or apple juice instead as these are safe to drink with Viagra.

Do not drink alcohol

If you’re planning on using Viagra and want to reduce side effects, it’s better to avoid drinking alcohol. Taking Viagra after drinking alcohol makes it more likely for you to experience headaches and flushing. If these particular side effects are an issue for you, try to limit your alcohol intake.

Drinking too much alcohol can have an impact on your sexual performance. Alcohol can cause problems like erectile dysfunction and premature ejaculation. While it’s hard to define what ‘too much’ alcohol means, you should be aware of how you’re feeling when you’ve been drinking. If you start to feel tipsy or drunk, try to avoid any more alcoholic drinks.

As a general guide, try to drink less than 14 units of alcohol per week.

Stay hydrated

Staying hydrated is a simple way to reduce the side effects of Viagra. You can keep hydrated by drinking plenty of water throughout the day. Aim to drink 6 to 8 glasses of water or more if it’s a hot day or if you sweat a lot due to being active (such as exercising).

If you are dehydrated, you might start to feel dizzy or tired, which can be confused with the side effects of Viagra. Being dehydrated can also affect your erection, as water makes up a large part of your blood. If you do not have a good volume of blood you may not be able to maintain an erection, even if Viagra works to increase blood flow to your penis.
