What is Sildenafil?
Sildenafil citrate is the name of the active ingredient in the Pfizer impotence drug Viagra. Since Viagra came off patent in 2013, other pharmaceutical companies have been able to sell generic Sildenafil - also known as generic Viagra - to patients in need of erectile dysfunction medication.
Sildenafil is a popular solution for men suffering from impotence who wish to have greater confidence in their ability to get and maintain an erection.
Sildenafil is medically equivalent to Viagra, offering an equally effective solution to male erectile dysfunction issues at a significantly lower cost. It can be prescribed to men:
- Of all ages
- No matter how severe erectile dysfunction may be
- Who have undergone a prostatectomy or have had partial removal of their prostate
How does Sildenafil work?
Sildenafil enables men with erectile dysfunction to respond to sexual stimulation. It works by helping to relax the blood vessels in the penis, allowing blood to flow into the two large chambers and achieve a hard erection. Sildenafil only assists the development and maintenance of an erection when sexually stimulated, however, and does not result in an irreversible state of arousal.
How to take Sildenafil
Take Sildenafil approximately one hour before you intend to have intercourse to achieve best results. Typically the window in which this erectile dysfunction treatment works is between 30 minutes and 4 hours, enabling you to achieve a hard erection during sexual arousal.
A tablet should be taken with water and may be ingested at meal times or between meals. It is worth noting, however, that when taking Sildenafil during or soon after a heavy, high fat meal, it may take longer for the drug to begin working.
The recommend starting dose for Sildenafil is one 50mg tablet taken 1 hour before sexual activity. Always follow the directions attached to your prescription, and if in doubt, consult a health professional before ingesting any medicine.
If you achieve the desired effect but suffer from unwanted side effects as a result of taking a 50mg sildenafil tablet, try lowering the dose to 25mg the next time you require it. Should you try a 50mg tablets four times without the desired effect, and you are not experiencing side effects, it is possible to increase the dose to 100mg.
If, after trying 100mg 8 separate times without effect, you should cease treatment and consult your doctor. You should not take sildenafil more than once a day as this will have not increase the effectiveness and may increase the likelihood of experiencing side effects.
Do not use other erectile dysfunction medicines or treatments at the same time as sildenafil. Mixing sildenafil with Viagra, Levitra or Cialis or another impotence drug can be dangerous for your health. It is also worth discussing any other medicines with your doctor before any course of erectile dysfunction treatment. Some drugs may interact with sildenafil or counteract its effectiveness.
Avoid drinking too much alcohol when taking sildenafil. Drinking alcohol can increase the likelihood of certain side effects, such as headaches and dizziness. Excessive consumption of alcohol also counteracts the effectiveness of any impotence medication and makes it harder to establish an erection.
Like all medicines, Sildenafil can cause some side effects in a minority of cases. These effects are usually mild to moderate and typically do not last longer than a few hours. Side effects are more commonly seen among men who require a higher dosage to obtain the desired effects.
Such side effects may include:
- Upset stomach
- Stuffy or runny nose
Drinking alcohol at the same time is more likely to cause the onset of these side effects.
In rare cases, temporary changes in colour vision have been documented, with men complaining of being more sensitive to light or experiencing blurred vision.
If you begin to develop signs of an allergic reaction to a dose of Sildenafil, such as: hives; swelling of the face, lips, tongue or throat; difficulty breathing, then it is important that you seek immediate medical attention.
If your erection proves to be painful or lasts longer than 4 hours (prolonged erections can damage the penis), stop taking your Sildenafil medication and discuss the problem with your pharmacist or GP.
What is the recommended dosage of Sildenafil?
Sildenafil is available in 25mg, 50mg and 100mg doses. If you are new to Sildenafil, your doctor will likely recommend starting with a 50mg dose. Please see our ‘how to use’ tab for more guidance on strengths.
How long does it take for Sildenafil to take effect?
Sildenafil usually takes 30 to 60 minutes to take effect. For best results, take it around 30 minutes before sexual activity.
How long does Sildenafil last?
Sildenafil can last for up to 4 hours, however, its effects will start to decrease after around 2 hours.
Does Sildenafil keep you hard after coming?
If you take Sildenafil and ejaculate, your penis will soften. Sildenafil will, however, help you to recover and regain an erection more quickly.
Can I take Sildenafil every day?
It is safe to take Sildenafil every day, providing that you stick to the recommended dosage and rules of use.
Can I take Sildenafil with alcohol?
Excessive alcohol consumption may prevent Sildenafil from working. For best results, drink alcohol moderately or don’t drink at all.
Can I take Sildenafil alongside other ED medication?
No - never combine erectile dysfunction medications. Taking two different ED medications at the same time may result in an overdose and unwanted side effects.
Why is Sildenafil so cheap?
Sildenafil is a generic drug. This means that although it isn’t sold under a brand name, it has the exact same ingredients as branded alternatives. Due to this, Sildenafil can be sold at a much cheaper price than Viagra, its branded equivalent.
What is the difference between Sildenafil and Viagra?
There is no discernible difference between generic Sildenafil and its branded counterpart, Viagra. Sildenafil as an unbranded tablet is medically equivalent and equally effective, yet available at a much lower price. Generic medicines produced by reputable manufacturers contain the same active ingredient and are rigorously tested to prove that they possess the same strength and stability as a branded alternative.
