Sildenafil Sildenafil

What is Sildenafil?

It’s a cheaper alternative to Viagra. In Sildenafil generic tablets, there’s an ingredient called sildenafil citrate. You get it in Viagra too. It’s a type of medicine that helps to relax the blood vessels around the penis.

Erectile dysfunction happens when not enough blood can get into the penis. It’s understood to affect around half of all men aged between 40 and 70 to some extent. So it’s more common than you might think (and if you do experience it, you’re definitely not alone).

The culprit is tight blood vessels, which stop blood from flowing in. An enzyme called PDE5 is what causes this.

Sildenafil counters the effects of this enzyme, so blood can reach the penis. And then, hey presto - a firmer and longer-lasting erection.

Because Sildenafil is a generic, it’s cheaper than Viagra. But it contains the same drug and shouldn’t be any less effective.

How does Sildenafil work?

Sildenafil citrate is a type of drug called a PDE5 inhibitor, which just means that it stops the PDE5 enzyme from tightening up blood vessels in your penis. This allows more blood to flow into your penis, and makes it easier for you to get a harder, longer lasting erection.

So Sildenafil looks after your physical needs. It does fall short of being an aphrodisiac though, so you’ll have to be aroused for it to work.

What Sildenafil dosage is right for me?

Sildenafil tablets come in 25mg, 50mg and 100mg doses. So exactly the same doses as Viagra.

If you’re taking it for the first time, you’ll normally start on Sildenafil 50mg. If you take this dose and it works well but you get mild side effects, our clinician will suggest lowering your dose to 25mg.

Starting on a 25mg dose may also be recommended if you have any risk factors which make you more prone to side effects (like diabetes for example).

Sildenafil 100mg is only for when you’ve tried 50mg and it hasn’t been strong enough. It’s the absolute maximum dose.

How to take Sildenafil

Take Sildenafil one hour before you plan to have sex, and swallow your tablet whole with water. It should take no more than between half an hour and an hour to work. Never take Sildenafil more than once in any 24 hour period.

Stick to the dose prescribed for you by our clinician. If you take more Sildenafil tablets than you should, seek medical attention.

If you get any serious side effects, go to your nearest hospital as soon as possible. This includes any signs of an allergic reaction, chest pain, or an erection that lasts for four hours or more and won’t go away on its own.

How long does Sildenafil last?

Sildenafil remains active in the body for up to five hours. As long as you take the tablet correctly, it should give you plenty of time to have sex with your partner. If you find it doesn’t last long enough for sex though, let our clinician know, and they can discuss strengthening your dose with you.

What should I do if Sildenafil doesn’t work?

If it doesn’t work for you, get in touch with our prescriber. They’ll be able to suggest a different dose or an alternative drug. You just need to log into your account and send our clinician a message. Adjusting your subscription plan is really easy if you want to switch to a different treatment.

FAQ: Sildenafil

Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.

How effective is Sildenafil?

Answer:
For most men who take Sildenafil, it works at the first or second time of asking.

The effectiveness of Sildenafil has been reviewed in clinical studies. It helped to improve erections in:

63% of men using the 25mg dose
74% of men using the 50mg dose
and 82% of men using the 100mg dose.

If you take Sildenafil but it doesn’t work as well as you’d like it to, our clinician can either help you find a more suitable dose or recommend alternative treatments for you.

Is there any difference between Viagra and Sildenafil?

Answer:
Sildenafil is a generic medication, so it’s less expensive than Viagra. Some people call Sildenafil ‘cheap Viagra’ for this reason, but it does the same thing in the body and is usually just as effective.

Viagra is a branded medication marketed by just one company, and the tablets have a distinct blue appearance and come in a recognisable box. Sildenafil isn’t always made by the same company, so the appearance of Sildenafil pills can vary from one manufacturer to the next.

Some men prefer Viagra over the Sildenafil generic. But the two drugs are clinically bioequivalent, which means there’s little to no difference between them in how well they work.

Sildenafil vs Tadalafil: which is better?

Answer:
It depends on the person taking it and what their sexual habits are. Even though they work in a similar way, the two are quite different. Tadalafil, the generic version of Cialis, is available as an on-demand weekend pill (that lasts for up to 36 hours) or a low dose every day pill.

Sildenafil is an on-demand pill that lasts for up to five hours. It’s usually a bit cheaper than Tadalafil, and for some men who don’t want to take medication every day, the five hour window for sex on Sildenafil does the trick.

Can you get Sildenafil for women?

Answer:
No. Neither Sildenafil nor drugs in the same class are suitable or safe for women. There is a drug that’s often referred to as the ‘female Sildenafil’ called Addyi, but it’s for hypoactive sexual desire disorder (HSDD). So it’s in no way similar to any licensed erectile dysfunction drug.

Why should I buy Sildenafil online with Treated?

Answer:
We’re keeping it easy. Tell us about your health and get expert advice from our clinicians. We’ll suggest suitable treatments and then we’ll leave the choosing to you.

All that’s left to do is decide on how often you’d like us to ship your medication to you, and how much of it you want to receive each time.

If there’s anything that you want to ask our clinicians about your treatment, you can. Anytime. Just log in to your Treated account and send them a message. They’ll get in touch with you on a regular basis to see how you’re getting on with your prescription. If you’d like to make any adjustments to your treatment or switch to something else, no problem.

Change, pause or cancel your subscription whenever you want.
