Can I buy Viagra online?

Viagra is a prescription-only medication. Any online pharmacy which is prepared to sell it without a prescription is untrustworthy. Online doctor services that can prescribe Viagra, like Superdrug Online Doctor, are the only safe and legal option if you want to buy Viagra online.

Can I buy Viagra over the counter?

As Viagra is a prescription-only medication, you won’t be able to buy it over the counter. There is an alternative to Viagra called Viagra Connect that can be bought over the counter without a prescription. It works in exactly the same way as other ED medications, except you don’t need a doctor to prescribe it to you before buying.

How much does Viagra cost?

Viagra is available from £5 per pill, but the patent on Viagra expired in April 2020. This means that medications that work in the same way as Viagra by using the same ingredients can be produced at a lower cost. Sildenafil is a generic, and more affordable, version of Viagra. Sildenafil is available from £3.75 per pill.

How does Viagra work?

Viagra belongs to a group of medications that are known as ‘PDE-5 inhibitors’. Viagra works by relaxing blood vessels in your penis, which increases blood flow to the area and helps you get an erection. For more in depth information, you can read more on our dedicated page about how viagra works.

Does Viagra make you aroused?

No, this is a common misconception. While Viagra can help you to get an erection, it doesn’t stimulate sexual arousal. Viagra will only work if you are already sexually aroused.

Does Viagra help you last longer?

If you’re having difficulty lasting longer in bed because you cannot maintain an erection, then Viagra can help to treat this. Viagra does not help if you are not lasting long enough due to premature ejaculation. If you want to find out more , our doctors break down whether Viagra can help you to last longer.

How long does Viagra take to work?

On average, it takes Viagra 30-60 minutes to work, so make sure you take it well before you plan to have sex. It’s also important to note that it may take longer for the Viagra to work if you’ve had a lot to eat, drink or are under the influence of drugs.

How long does Viagra last?

The effects of Viagra typically last between 2-3 hours, but can last up to 4 hours. This will depend on your dosage, your body’s metabolism, and other external factors. Some medication may interact with Viagra making it more or less effective so it's always important to check that it's safe to use with the medications you are taking.

How effective is Viagra?

There’s a reason why Viagra is the most common ED treatment. Viagra has been shown to be effective in 75% of men who take it, and in 2016 there were nearly 3 million prescriptions issued for Viagra in the UK alone. It’s important to know that Viagra and other ED medications don’t always work 100% of the time and there are some factors that can make it less effective. Eating a big meal, alcohol, and drugs are all things that can impact how Viagra works. It will also be less effective if you are not already aroused.

How do you take Viagra?

Only take one tablet at a time, up to 4 hours before you want to have sex. Swallow Viagra tablets whole with a glass of water or juice. Do not take Viagra with grapefruit juice, as this could trigger headaches or low blood pressure. Take Viagra as advised by your doctor or pharmacist.

How often can you take Viagra?

Viagra can be taken every day, but you can only have one tablet a day, even if it is a low dose. Taking more Viagra than you have been prescribed, or combining it with other ED medication, could cause side effects such as permanent damage to the penis so you should only ever take as prescribed by your doctor. 

How much Viagra should you take the first time?

Most men start off by taking Viagra 50mg, but if you feel like 50mg isn’t enough or it isn’t having the desired effect, you can ask your doctor if you can try a higher dosage. You should never change dose without speaking to your doctor first. You can also find out what it’s like to take Viagra for the first time.

Viagra can be taken in various different doses and your doctor will prescribe you a dose that they think is suitable for you, but it may take several tries to find the dose that works best

25mg Viagra

This the lowest available Viagra dosage. It has the lowest effect and is the best option for people who experience side effects on 50mg. This dose may be prescribed if you’re currently on any medications that may interact with Viagra as this will lower the chance of interactions. 

50mg Viagra

This is the starting dose for most men, and the most commonly used Viagra dose. This is because this dose is usually effective for most men, but it is also a good starting point to measure its effectiveness and your tolerance to it. From here, the dose can easily be reduced or increased to better suit your needs.

100mg Viagra

This is the highest Viagra dosage available. This is commonly prescribed to people who did not get the desired effect on lower doses. It is important to note that this dose has the highest chance of side effects.

Read on for answers to some of the questions our doctors get asked most frequently about Viagra and ED.

What is it like before and after Viagra?

Before taking Viagra, you may have trouble maintaining an erection during sex, which may result in issues to do with your sex life. Once prescribed, take Viagra up to 4 hours before you want to have sex. It takes 57 minutes on average for Viagra to reach its maximum concentration in the blood. This causes the blood vessels to relax, allowing blood to more easily flow to the penis.

Does Viagra make you last longer?

Viagra can help you to get and maintain an erection, so you can stay harder for longer if you struggle to keep an erection naturally. However, Viagra does not delay ejaculation so it will not make you last longer if you are orgasming too quickly. For more information, you can read our doctors’ advice on how to last longer, and if Viagra can help.

Can you take Viagra with alcohol?

No, Viagra should not be taken with alcohol, but it is usually safe in moderation. While alcohol is often used to overcome nerves and sexual anxiety, drinking too much can actually make it harder to get an erection - and can make Viagra less effective. Alcohol can also worsen the side effects of Viagra, even when drinking in moderation. Read what our doctors have to say about the risks of taking Viagra with alcohol.
