Sildenafil is used to treat both erectile dysfunction and pulmonary arterial hypertension (PAH). It became well-known as the active ingredient in Viagra. In June 2013, Pfizer’s patent for Viagra expired, opening a market for generic sildenafil citrate. As a result, men now have a choice between branded Viagra and more affordable generic sildenafil tablets. Sildenafil is a prescription medication, meaning that it's only available on prescription and should be taken exactly as prescribed to be fully effective. You can order sildenafil tablets online from our team of doctors and have them delivered to the (UK) address of your choice.
Sildenafil is the active ingredient in Viagra. It causes the release of nitrous oxide (NO), a chemical that enlarges the blood vessels in the penis during sexual stimulation. This allows for the necessary inflow of blood needed to cause an erection.
The Sildenafil dosage you need to take will depend on your age, gender, medical condition, your response to therapy and use of any interacting medication. 25, 50 and 100mg Sildenafil tablets are available. The recommended dose for most people is 50mg taken between 30 minutes and four hours prior to sexual activity. This dose can be increased to 100 or decreased to 25mg depending on adverse effects and efficacy. Ideally, it should be taken on an empty stomach. If you take Sildenafil after eating, it will take longer to kick in. Your tablet should be swallowed whole with a drink of water. Sildenafil should not be taken more than once in a day.
Drinking grapefruit juice while using this medication can be dangerous. It may increase the drug's concentration in your blood, causing more pronounced Sildenafil side effects.
The following patients should stick to 25mg Sildenafil tablets:
Sildenafil actavis and sildenafil clonmel are types of medicine that contains the active ingredient sildenafil. They are used to help treat erectile dysfunction.
The only difference between sildenafil and Viagra is the branding, and packaging, of the medication.
Viagra is the brand name for the generic medicine known as sildenafil. Sildenafil and Viagra are ‘medically equivalent’, meaning that they both work in the same way, and contain the same active ingredients.
Sildenafil is used to treat erectile dysfunction, when used alongside sexual stimulation. Sildenafil treats erectile dysfunction by relaxing the blood vessels in your penis, which allows the blood flow to increase. Good blood flow to the penis is necessary for a strong and healthy erection.
Sildenafil is not an aphrodisiac. It will not make you sexually stimulated or raise your libido on its own.
You can drink up to 2-3 units of alcohol, safely, while taking sildenafil. Many people find that alcohol helps them overcome their anxieties around sex.
However, too much alcohol can make your problems with erectile dysfunction worse. Drinking more than 2-3 units might have a negative effect on your sexual function.
Always take your medication exactly as it was prescribed to you by your doctor.
As a rule, you should take your sildenafil tablets up to 1 hour before having sex. Swallow your sildenafil tablets whole, without chewing or crushing them. Take your sildenafil tablets with or without water, as desired.
Sildenafil works best on an empty stomach. It won’t be as effective immediately after eating a heavy, high-fat meal.
When using this medication, you may experience one or more of the following, common Sildenafil side effects:

Nitrate medications include the following:
Glyceryl trinitrate, isosorbide mononitrate and isosorbide dinitrate (used for angina or heart failure - if you experience chest pain after taking this medicine DO NOT use nitrates to treat it):
You should not start taking Sildenafil tablets without first consulting your doctor or pharmacist. Inform them of your full medical history, paying particular attention to the following:
