Just a few questions from our Pharmacist before you checkout to make sure this medicine is safe for you.
What is sildenafil?
Sildenafil is a medication that can treat erectile dysfunction, helping you to get and maintain an erection during sex. Sildenafil is the active ingredient in Viagra, which means that this medication works in the same way as the branded product, and is just as effective. If you’re looking for a way to treat your premature ejaculation and help to keep an erection, sildenafil could be the ideal treatment for you.
How to take this medication
You should follow the dosage and any instructions given to you by your doctor when taking this product. The usual dose you’ll be given to begin with is 50mg of sildenafil, but this may be increased or reduced by your doctor depending on how you react to the medication. Take your tablet around an hour before you are planning on having sex, and swallow whole with a glass of water. You can take this product with food, but be aware that it may take longer to work if you have eaten a heavy meal. You will need to be sexually stimulated for sildenafil to work, just as you would to obtain an erection without taking this medication.
How will sildenafil treat my erectile dysfunction?
Sildenafil is an active ingredient which is part of a group of medications called phosphodiesterase type 5 (PDE5) inhibitors. It treats erectile dysfunction by relaxing the blood vessels in your penis, making it easier for blood to flow to the area. This makes it easier for your penis to get the blood flow it needs to become erect and stay erect.
