Sildenafil Tablets

Sildenafil is a generic medication used to treat erectile dysfunction. It contains the active ingredient sildenafil, which is the same ingredient in Viagra. Sildenafil is a more affordable option for ED. It can help you get and keep an erection, as long as you are sexually aroused. It comes in tablet form and usually takes 30 to 60 minutes to work.

Sildenafil works by relaxing your blood vessels to allow more blood to flow to the penis. This blood flow causes an erection and makes sildenafil an ideal treatment for erectile dysfunction.

Sildenafil belongs to a group of medications called PDE-5 (phosphodiesterase type 5) inhibitors. This means it works to block PDE-5 enzymes in your penis to widen your blood vessels, helping you to get an erection. Generally, you must be sexually aroused for sildenafil to work and give you an erection.

How long does sildenafil last?

Sildenafil lasts for around 4 hours after you take it. You can have more than 1 erection during this time, but only if you are sexually aroused.

How long does it take to work?

Sildenafil starts working 30-60 minutes after taking it, so you should aim to take it an hour before you want to have sex.

Sildenafil is the most popular erectile dysfunction medication in the world, and works for up to 74% of men who try it. While sildenafil is not a cure for erectile dysfunction, it is a highly effective medication that helps you to get an erection when you need one.

Can I get sildenafil on the NHS?

Yes, you should be able to get sildenafil on the NHS. You will need to contact your GP to see if they offer sildenafil on prescription, and then make an appointment. You will then need to talk to your doctor about your erectile dysfunction, and then get a prescription from them. You may need to return to the GP to renew your prescription.

For best results, take sildenafil 30 minutes to 1 hour before having sex. The effects of sildenafil can last for up to 4 hours.

Do not take more than 1 sildenafil tablet a day. Swallow it whole without chewing or crushing it. A glass of water will help you swallow it but you do not need to take it with food.

To help get the best results when taking sildenafil:

• avoid drinking grapefruit juice
• only have small amounts of alcohol (up to 3 units per day), as having a large amount of alcohol might make it difficult to get an erection
• take sildenafil on an empty stomach, as eating before taking sildenafil can make it take longer to work

If you have taken sildenafil and still cannot get an erection, do not take another dose. Try again the next day and make sure you avoid fatty foods and alcohol.

Erectile dysfunction can sometimes be caused by an underlying health condition, so speak to your doctor about a health check and other options if sildenafil does not work.

Sildenafil is available in 3 doses; 25mg, 50mg, and 100mg. 50mg is suitable for most men, but if you are experiencing disturbing side effects then lowering your dosage to 25mg may help. If you are not getting the desired effect on 50mg but you aren’t getting side effects on this dose, then 100mg may be a better option for you. Speak to your doctor first who will help choose a suitable dose for you.

What is the starting dose for Sildenafil?

The usual starting dose is 50mg, but you may be started on a lower dose of 25mg if you take certain medications. The highest dose is 100mg, but you should not take more than prescribed. Generic Sildenafil has the same dosages as Viagra.

You might have some side effects when taking sildenafil, but not everyone gets them.
