    What is Sildenafil and what is it used for?

    Doctors prescribe Sildenafil for erectile problems. Erectile dysfunction can occur as a man’s erectile capacity gradually decreases in later life. But this condition can also be caused by stress, depression or physical complaints such as prostate problems and cardiovascular disease. Excessive use of alcohol or drugs can also lead to impotence.

    Sildenafil is an effective erection remedy available in capsule form. This medication is known in the medical world as a PDE5 inhibitor.

    Sildenafil is the brand name of Viagra, developed by Pfizer and is only available through a doctor and on prescription.

    How does Sildenafil work?

    With erectile dysfunction, the problem is that the penis does not become firm or remain firm for long enough. Sildenafil relaxes the tension in the blood vessels, which stimulates and increases the blood flow. This keeps the erection in place during sexual activity.

    As well as taking Sildenafil, sexual stimulation is also required to achieve results. Sildenafil usually takes effect after one hour, and Sildenafil’s active effectiveness lasts 4 to 5 hours on average.

    How do you take this medicine?

    Sildenafil capsules should be taken orally with a glass of water. It is important to take this medication one hour before sexual activity.

    If you experience nausea or an upset stomach, it is better to take the capsule with some food. But note this will alter how long before the medication takes effect. Taken with food, it takes a little longer to be absorbed into the body.

    Sildenafil capsules may only be taken once a day. Otherwise the chance of side effects is considerably increased. If the effect is insufficient at a low dose, the dosage can be increased. Always discuss this with your doctor.

    Do you need a prescription?

    Sildenafil is only available on prescription. A prescription is required for both Sildenafil 25 mg, Sildenafil 50 mg and Sildenafil 100 mg.

    A doctor has to decide whether Sildenafil, the active ingredient, is suitable for use. This may depend on medical conditions such as cardiovascular disease, for example, or the use of other medications.

    You cannot purchase Sildenafil prescription-free. Always check that websites where Sildenafil is offered are properly authorised. And also note the Sildenafil price very carefully. If this medication is offered for cheaply, this may suggest the website is unreliable and the products may not be authentic.
