What Is Viagra?

Viagra, often known as the "little blue pill", is a popular treatment for erectile dysfunction (ED) in men aged 18 and over. It contains sildenafil, an active ingredient that belongs to a group of medicines called PDE5 inhibitors.

Viagra boosts blood flow to the penis, helping you get and keep an erection. It only works if you are sexually aroused and does not cause an erection by itself.

Since its release in 1998, Viagra has transformed the treatment of ED and has become a trusted choice for many men.

For personalised advice, speak to your doctor or pharmacist.

To learn more, read our A-Z guide to Viagra.

What is Sildenafil?

Sildenafil is the active ingredient in Viagra and is widely used to treat erectile dysfunction (ED). It belongs to the PDE5 inhibitor group of medicines.

Sildenafil increases blood flow to the penis when you are sexually aroused, making it easier to get and maintain an erection. Like Viagra, it only works with sexual stimulation.

You can choose between branded Viagra and generic Sildenafil. Both work in the same way and are equally effective. However, generic Sildenafil is often more affordable. Both options are available at UK Meds.

If you are unsure which is right for you, ask your doctor for advice.

How Does Viagra Work?

Viagra (sildenafil) helps men with erectile dysfunction by improving blood flow to the penis. It belongs to a group of medicines known as PDE5 inhibitors.

Here’s how it works:

• Viagra relaxes the blood vessels in the penis.
• This lets more blood flow into the area, helping to create an erection.

Viagra only works if you are sexually aroused. It will not cause an erection without stimulation.

How Effective Is Viagra?

Viagra has been shown to be effective for most men:

• 50mg dose: Works for 74% of men.
• 25mg dose: Works for 62% of men.
• 100mg dose: Works for 82% of men.

This is compared to lower success rates seen with a placebo (a dummy pill).

You can boost the effectiveness of Viagra with simple lifestyle changes.

Viagra remains a trusted and proven treatment for ED. Speak to your doctor to find the right dose for you.

Why Do I Need a Prescription for Viagra?

Viagra is a prescription-only medicine. A doctor must assess whether it is safe for you to use because Viagra might:

• Interact with other medicines you are taking.
• Be unsuitable if you have certain health conditions like heart disease or low blood pressure.

You can also choose Viagra Connect, available without a prescription. However, you will still need a consultation with a registered medical prescriber to ensure it is safe for you.

What Causes Erectile Dysfunction?

Erectile dysfunction (ED) is a common condition with many physical and psychological causes.

Physical causes include:

• Obesity
• Heart disease
• High blood pressure

Psychological causes include:

• Stress
• Anxiety
• Depression

Sometimes, ED can be caused by a mix of physical and psychological factors. For personalised advice, speak to a healthcare professional or read more about the causes of erectile dysfunction.

How Should I Take Viagra?

To use Viagra properly:

1. Timing: Take one tablet with a glass of water about 1 hour before sex.
2. Dosage: Take only one tablet in 24 hours. Never exceed this amount.
3. Food: For the best results, take Viagra on an empty stomach or after a light meal. Heavy or greasy foods can delay how quickly it works.
4. Alcohol: Limit or avoid alcohol. Drinking can reduce Viagra’s effectiveness and make erections harder to achieve.

Always follow your doctor’s instructions. If you have any concerns, speak to your healthcare provider.

When Should I Take Viagra?

Viagra usually starts working within 30 to 60 minutes. For the best results:

• Take it about 1 hour before you plan to have sex.
• Try not to take it more than 4 to 6 hours before, as its effects may wear off.

If too much time passes and it doesn’t work, wait until the next day for another dose. Always follow your doctor’s advice.

How Long Does Viagra Take to Work?

Viagra usually begins to work within 30 to 60 minutes. It’s best to plan ahead and take it about 1 hour before sexual activity.

What Can Affect How Quickly Viagra Works?

• Sexual Arousal: Viagra only works if you are sexually stimulated. Foreplay can help.
• Food Choices: Heavy meals can delay its effects. Take it on an empty stomach or after a light meal for faster results.
• Alcohol Consumption: Alcohol can make Viagra less effective. It’s best to avoid alcohol if you want the best results.

By planning ahead and considering these factors, you can get the most out of your treatment. If you have questions, speak to your doctor or pharmacist.

How Long Does Viagra Last?

Viagra can stay effective for up to 4 hours. However, the exact duration can vary depending on your body.

If you plan to have sex in the evening, avoid taking it too early, as you can only take one tablet per day. For best results, take it about 1 hour before sex.

What Can Affect How Long Viagra Lasts?

• Age: Older adults may find Viagra lasts longer as the body processes it more slowly.
• Health: Conditions like diabetes or heart disease can affect how well it works.
• Diet: Heavy meals can reduce how long Viagra stays effective.
• Alcohol: Drinking can shorten how long Viagra works and lower its effectiveness.

By taking it at the right time and avoiding heavy meals and alcohol, you can get the best results. Always follow your doctor’s guidance.

How Often Should You Take Viagra?

You should take only one tablet a day. Taking more, such as two doses in one day, can increase the risk of side effects and serious health problems, including permanent damage to your penis.

What to Do if Your Dose Feels Wrong:

• If your dose feels too strong or too weak, do not change it yourself.
• Speak to your doctor. They can adjust your prescription safely.

Always follow your doctor’s instructions carefully to avoid unnecessary risks.

How Should You Store Viagra?

To keep Viagra safe and effective:

• Storage: Store at room temperature in a closed container.
• Avoid: Keep away from direct sunlight, moisture, and heat.
• Disposal: Do not use Viagra after the expiry date. Speak to your pharmacist about safe disposal.

Always store medicines safely and out of reach of children.

How Should You Dispose of Viagra (Sildenafil) Tablets?

To safely get rid of unused or expired Viagra:

• Take them to your local pharmacy for safe disposal.
• Never throw them in the bin or flush them, as this can harm the environment.

If unsure, ask your pharmacist for advice.

Does Viagra Expire?

Yes, Viagra has an expiry date and can become less effective or unsafe after that time.

• Check the expiry date on your packet and do not use Viagra after this date.
• Expired medication: Return it to your local pharmacy for safe disposal and get a new prescription.

Using expired medicine is not recommended as it might not work properly or could be unsafe. Always check your medication and speak to a pharmacist if needed.

Below UK Meds answer the most commonly asked questions from our ED patients about Viagra:

Does Viagra work for everyone?

Viagra helps most men, but it does not work for everyone.

• If you have tried 25mg or 50mg several times without success, your doctor may suggest increasing the dose to 100mg, which is the highest available strength.
• If 100mg still does not work, Viagra may not be the right treatment for you.

Other erectile dysfunction treatments are available. Your doctor can help you find an alternative that suits your needs. Always speak to a healthcare professional before changing your medication.

Will Viagra (sildenafil) make me last longer in bed?

No, Viagra (sildenafil) does not make you last longer during sex. It is designed to help you get and keep an erection, but it does not affect how long you last or prevent premature ejaculation.

If you want help lasting longer in bed, speak to your doctor or healthcare provider. They can offer advice or suggest treatments that suit your needs.

For more information, read our guide: Does Viagra make you last longer?.

Will Viagra (sildenafil) make my erection bigger?

No, Viagra (sildenafil) will not increase the size of your penis.

It works by boosting blood flow to the penis, helping you achieve and maintain an erection when you are sexually aroused. However, it does not change your penis size.

If you have any questions about how Viagra works, speak to your doctor or pharmacist for personalised advice. Always use Viagra as directed for safe and effective results.

Does Viagra (sildenafil) help to treat premature ejaculation?

Viagra (sildenafil) is not made to treat premature ejaculation (PE), but it may help some men.

• What studies say: Research, including a study by Wang et al. (2007), suggests that sildenafil could be helpful for PE.
• Improves confidence: Other studies, like McMahon et al. (2005), found that while sildenafil does not directly delay ejaculation, it may boost confidence and improve control.

If you experience premature ejaculation, speak to your doctor or healthcare provider. They can advise whether sildenafil is right for you or suggest other treatments that better suit your needs.

Can you take Viagra if you have high blood pressure?

If you have high blood pressure (hypertension), always speak to a doctor, pharmacist, or healthcare provider before taking Viagra.

• A healthcare professional will check if Viagra is safe for you by looking at your medical history and any medicines you are currently taking.
• If Viagra is not suitable, they may suggest an alternative treatment for erectile dysfunction (ED) that will not affect your blood pressure.

Always follow your doctor’s advice to make sure your treatment is safe and works properly.

Is it safe to take nitrate medicines and Viagra (sildenafil) at the same time?

No, it is not safe to take nitrate medicines (for chest pain) and Viagra (sildenafil) at the same time.

• Why not? Taking them together can cause a dangerous drop in blood pressure, called fatal hypotension. This can lead to fainting, dizziness, or life-threatening complications (Chamsi-Pasha, H., 2001).
• Examples of nitrate medicines: Nitroglycerin, isosorbide dinitrate, or any medicine that acts as a nitric oxide donor.

Always consult your doctor, pharmacist, or healthcare provider before taking Viagra if you are using nitrate medicines. They can advise on safer alternatives for treating erectile dysfunction.

Is Viagra (sildenafil) safe for men with heart disease?

Viagra (sildenafil) may not be safe for men with certain types of heart disease or related conditions.

• Why? Viagra works by widening blood vessels to improve blood flow. In men with heart disease or those taking heart medicines, this can cause a dangerous drop in blood pressure.
• Heart disease and ED: Erectile dysfunction can sometimes be an early sign of heart disease. Conditions like atherosclerosis (narrowed arteries) may affect blood flow to the penis before causing problems elsewhere in the body (British Heart Foundation, 2022).

What should you do?

• Consult your doctor: Always speak to a doctor, pharmacist, or healthcare provider before using Viagra or any erectile dysfunction treatment if you have heart disease.
• Get a full assessment: Your doctor can find the cause of your ED and recommend safe, effective treatments tailored to your needs.

Looking after your heart health is vital, never take ED medicines without medical advice if you have heart problems.

Is Viagra (sildenafil) safe to take after a heart attack?

If you have had a heart attack, always speak to a doctor or healthcare provider before taking Viagra (sildenafil).

• Why? After a heart attack, your body may still be healing. Taking Viagra could cause serious side effects, such as dangerous drops in blood pressure.
• Individual assessment: Your doctor will check your heart health and current medications to decide if Viagra is safe for you, or suggest a different treatment.

Always follow medical advice to make sure any treatment you take is safe and will not put your health at further risk.

Can I drink grapefruit juice when using Viagra?

No, you should avoid drinking grapefruit juice when taking Viagra (sildenafil) for erectile dysfunction.

Why?

Grapefruit juice can affect how your body processes sildenafil. It can cause higher levels of the medicine to build up in your blood, which raises the risk of side effects such as:

• Low blood pressure
• Headaches
• Flushing

To stay safe, drink water or other non-interacting drinks when using Viagra. If you are unsure, ask your doctor or pharmacist fo

Can I take Viagra and alcohol at the same time?

It is best to avoid or limit alcohol when taking Viagra (sildenafil).

Why?

Alcohol can interact with Viagra by lowering your blood pressure, which increases the risk of side effects such as:

• Lightheadedness
• Dizziness
• Flushing
• Fainting
• Heart palpitations
• Headaches

To stay safe and get the best results from Viagra, try to drink little or no alcohol while using it. If you have any questions or worries, speak to your doctor or pharmacist for advice.

Is Viagra dangerous?

For most people, Viagra (sildenafil) is a safe and effective treatment for erectile dysfunction or pulmonary hypertension. However, some people may need to take extra care.

Key points to consider:

• Mild side effects: Most people experience few or no side effects when taking Viagra.
• Dangerous interactions: If you take medicines called nitrates (often used for chest pain), Viagra can cause a serious drop in blood pressure.

How to stay safe

• Always speak to your doctor before starting Viagra to make sure it is safe for you.
• Avoid taking Viagra with nitrates or any other medicines that could interact with sildenafil.

By checking with a healthcare professional, you can make sure Viagra is both safe and right for your needs.

Is it ok for women to take Viagra?

Viagra (sildenafil) is not recommended for women to treat sexual problems, as there is no strong evidence that it works for this purpose.

When could Sildenafil be prescribed for a woman?

Sildenafil may be prescribed to women for pulmonary hypertension, a condition where there is high blood pressure in the lungs.

If you are a woman thinking about taking Viagra or have questions about its safety, always consult your doctor or healthcare provider. They can offer advice and suggest treatments that are safe and suitable for you.

For more information, visit trusted health sites like the NHS website.

Can I split Viagra tablets?

Yes, you can cut, crush, or swallow Viagra tablets whole, depending on the dose your doctor prescribes.

Why split a tablet?

• Splitting can help adjust your dose if your doctor advises it.
• It might also save you money if recommended by your healthcare provider.

Important considerations

• Only split tablets if your doctor or pharmacist says it is safe.
• Use a pill cutter to make sure the doses are even.
• Always follow the instructions with your medicine to keep it safe and effective.

If you are unsure, ask your doctor or pharmacist for advice.

Can you tell if a man has taken Viagra?

No, there are no medical tests that can show if someone has taken Viagra. However, if your partner knows about your past erection problems, they might notice changes, such as stronger erections.

Taking Viagra is nothing to be embarrassed about. Being open with your partner about using erectile dysfunction treatment can build trust and support. Remember, sexual stimulation is needed for Viagra to work properly.

If you have any concerns, speak to your doctor or healthcare provider for advice that suits you.

Can teenagers take Viagra?

Teenagers aged 18 or over may be prescribed sildenafil (generic Viagra) for erectile dysfunction, but only if a doctor approves it.

For younger patients:

Sildenafil can also be prescribed on the NHS to children over the age of 1 to treat pulmonary hypertension (a type of high blood pressure in the lungs).

Important Considerations

• Always consult a doctor: Sildenafil should only be used under medical supervision to make sure it is safe and right for the individual.
• Not for recreational use: Viagra should only be taken to treat medical conditions like erectile dysfunction or pulmonary hypertension, as directed by a healthcare professional.

For personalised advice, speak to your doctor or pharmacist.

Does Viagra increase testosterone?

The link between Viagra (sildenafil) and testosterone levels is not clear, as studies show mixed results.

• Some studies suggest: Taking sildenafil may cause a slight increase in testosterone levels (Spitzer et al., 2013 and Reuters, 2012).
• Other studies suggest: Low testosterone might make Viagra less effective for treating erectile dysfunction (BBC, 2010).

Remember:

• Viagra is designed to improve blood flow to the penis and treat erectile dysfunction. It is not meant to boost testosterone levels.
• If you think you have low testosterone, speak to your doctor. They can test your hormone levels and recommend the right treatment for you.

Always follow professional medical advice when using Viagra or if you have concerns about your hormones.

Will Viagra affect my fertility?

The NHS states there is no strong evidence that Viagra (sildenafil) affects fertility in men or women.

In fact, Viagra may help if you are trying for a baby and need support with getting and keeping an erection during sex.

If you are worried about fertility or using Viagra, speak to your doctor for personalised advice.

What alternative forms of ED treatments are available?

If Viagra is not suitable for you, or you want a longer-lasting option, there are many alternatives. These include prescription medicines, over-the-counter treatments, lifestyle changes, and natural remedies.

These changes can also help manage health conditions like high cholesterol or heart disease that may cause ED.
