Viagra is a brand-name oral tablet medicine that is prescribed to support patients with erectile dysfunction. The active ingredient Sildenafil is also sometimes prescribed to patients with pulmonary hypertension. The medicine is available as a prescription from your doctor. Viagra Connect is available to purchase online at Pharmacy2U without a prescription. However, you will need to start a free online consultation with one of our expert clinicians to check your suitability.
What is Viagra used for?
For patients with erectile dysfunction, Viagra is used to help maintain an erection during sexual activity. Viagra alone will not cause an erection; sexual arousal is still required for it to work. For patients with pulmonary hypertension, Sildenafil is used to relax blood vessels in the chest.
How does Viagra work?
If you have erectile dysfunction Viagra works by temporarily increasing blood flow to your penis while you get sexually excited. If you have pulmonary tension Sildenafil works by lowering the blood pressure in your lungs to make it easier for your heart to pump blood around your body.
How do I take Viagra?
Viagra is typically taken in tablet form and is most effective when swallowed with a drink of water (but not grapefruit juice) on an empty stomach and at least an hour before engaging in sexual activity. It may take longer for Viagra to take effect if it is taken with food.
What is the dosage for Viagra?
The usual dosage and strength of Viagra tablets for patients with erectile dysfunction is usually prescribed at 50mg only when needed and must not be taken more than once a day. Your doctor can increase and decrease your dosage depending on its effect, which usually ranges between 25mg and 100mg.
The usual adult dose of Sildenafil for patients with pulmonary tension is 20mg taken 3 times a day. Doses for children can range from 10mg to 20mg taken 3 times a day depending on their weight.
How long does Viagra take to work?
It generally takes 30 to 60 minutes for Viagra to take effect. You should take it at least an hour before you want to engage in sexual activity but you can take it up to 4 hours before.
How long do the effects of Viagra last?
Your age, health, and diet can all affect the amount of time the effects of Viagra last. Independent studies have shown that Viagra can last for around 4 to 6 hours.
What are the side effects of Viagra?
The most common side effects are headaches, feeling sick, indigestion and dizziness. However, many people have no side effects or only mild ones. It can be dangerous to take Viagra if you also take medicines called nitrates as the combination can cause a dangerous drop in blood pressure. Always ask your doctor or pharmacist, if you’re unsure whether you’re taking a nitrate.
Do not drink grapefruit juice if you’re taking Sildenafil for pulmonary hypertension as it affects the way the medicine works. Common medications may also cause interactions with Viagra so it’s important to speak to your doctor about how drug interactions should be managed.
What age do I have to be to take Viagra?
Most men aged 18 and over can take Viagra for erectile dysfunction. Viagra is not suitable for some people so you need to speak to your doctor to make sure it’s safe for you. Most adults and children aged 1 year and over can take Sildenafil for pulmonary hypertension.
Can I still drive after taking Viagra?
Viagra does not make you sleepy and is therefore usually safe to drive or ride a bike when taking this medication. You should not drive if you experience side effects such as dizziness or blurred vision.
Can only males take Viagra?
Viagra is only prescribed to men aged 18 and over for erectile dysfunction. Most adults and children aged over 1 year can take Sildenafil for pulmonary hypertension.
Where is Viagra available?
Viagra is a prescription-only medication and therefore not available to purchase in the UK without a valid prescription from a healthcare professional. Viagra Connect is also available and works in the same way as Viagra to treat ED. The only difference is you do not need a prescription for Viagra Connect.
