What Is Perrigo Sildenafil?

Perrigo Sildenafil is an over-the-counter (OTC) treatment for erectile dysfunction (ED). It contains the same active ingredient as Viagra Connect - Sildenafil, which belongs to a class of medicines called phosphodiesterase type 5 (PDE5) inhibitors.

Perrigo are a manufacturer of many over-the-counter products, including Nytol, Tiger Balm and Beconase. In early 2020, they launched a generic, over-the-counter sildenafil as an alternative to Viagra Connect and other OTC sildenafil, such as Aronix.

Over-the-counter sildenafil is only available in 50mg tablets. Strengths of 25mg and 100mg of silenafil are only available on prescription.

While you don’t need a prescription to buy Perrigo sildenafil online, you will need to answer some questions about your general health and your erectile dysfunction to ensure it is suitable for you.

Where Can I Buy Sildenafil Over The Counter for Erectile Dysfunction?

You can buy Perrigo Sildenafil over the counter from pharmacies, or via an online pharmacy such as Prescription Doctor.

Our convenient service makes it quick and straightforward to order ED treatment from wherever you are. Simply fill out our online questionnaire and, if your order is approved before 3pm, our UK based pharmacy will dispatch your item the same day.

If you are unsure which ED treatment is suitable for you, you can contact one of our online doctors.

How Does Sildenafil Work For Erectile Dysfunction?

Sildenafil works by relaxing the blood vessels within the penis. This improves blood flow to the penis when you are sexually aroused, making an erection more easily achievable.

While Sildenafil can make it easier for an erection to occur when sexually excited, it does not cause an erection by itself. Moreover, sildenafil is not an aphrodisiac and does not increase your sex drive.

How Long Does Sildenafil Take To Work?

Sildenafil usually takes between 30 and 60 minutes to start working for erectile dysfunction.

Taking sildenafil with a heavy meal may delay the effect, while taking sildenafil on an empty stomach can help the medicine to take effect sooner.

You will not achieve a spontaneous erection after taking sildenafil. You and your partner should engage in foreplay to aid in sexual stimulation.

What should I Do If Sildenafil Does Not Work For Me?

According to the NHS, sildenafil is effective for more than two-thirds of men who take it. If in the first instance you find that Perrigo sildenafil does not work for you, try again at a later date.

If your ED persists, speak to your doctor. They may be able to determine the cause of your ED and discuss various treatments for erectile dysfunction with you.

You should not take more sildenafil if you find it ineffective at treating your erectile dysfunction. Taking more sildenafil than recommended can increase your risk of side effects, which can pose a risk to your health.

Are there non-medical treatments for erectile dysfunction?

Erectile dysfunction can have many underlying causes - both physical and psychological. Depending the on the cause of your ED, it may be possible to treat ED by treating the underlying cause.

If you are experiencing erectile dysfunction, you should speak to your doctor first before seeking treatment. They will be able to discuss with you the possible causes and suitable treatments available for you.

You may find it uncomfortable speaking openly about your ED problem, but it’s important to do so for you and your partner. Erectile dysfunction can be an indication of an undiagnosed condition, such as heart disease. Speaking to your doctor openly about your issue is the first step to treating your erectile dysfunction.

How Do I Take Perrigo Sildenafil for Erectile Dysfunction?

Perrigo sildenafil is only available in 50mg tablets for the treatment of ED in men. This is the maximum daily dosage, and you should only take one pill in any 24 hours period.

Swallow one sildenafil tablet whole with a glass of water an hour before sex.

Do not crush or chew the tablet.

If you find that the dosage is too weak or too strong, or if Perrigo Sildenafil does not help you to achieve or maintain an erection, you should speak to your doctor.

What should I do if I forget to take Perrigo Sildenafil when I should?

If you forget to take sildenafil when you should, you can take it as soon as you remember. However, you should not take an additional dose to make up for the one you missed.

What should I do if I take too much Perrigo Sildenafil?

If you take too much sildenafil, you may be at greater risk of developing and experiencing side effects. Inform your doctor immediately for expert advice.
