If you’ve been searching for effective erectile dysfunction (ED) treatments, it’s highly likely you’ve come across tadalafil. Tadalafil is a clinically proven ED medication that many men have been using for years to treat their erectile dysfunction symptoms.  

It’s highly effective and some men use it as an alternative to sildenafil (another popular ED treatment) if it didn’t help them achieve the results they wanted. In many cases, it’s preferred over sildenafil because its effect lasts longer and takes a shorter amount of time to kick in. 

But, to use tadalafil tablets as safely and effectively as possible, it’s important that you know the recommended starting dose. 

Tadalafil is one of the most versatile erectile dysfunction tablets out there and it comes in a variety of doses. Each has its own benefits for treating erectile dysfunction, and we’ll highlight what those are in just a second. For now, though, let’s learn a bit more about what tadalafil is and how it works. 

What is tadalafil used for?

Tadalafil is an erectile dysfunction treatment that stimulates harder, longer-lasting erections by allowing the blood vessels in the penis to stay relaxed and open. It achieves this by gently blocking the action of an enzyme called PDE5, which is why tadalafil is known as a PDE5 inhibitor. Other well known PDE5 inhibitors include Cialis, Viagra, sildenafil, Viagra Connect, and Tadalafil Daily

The recommended tadalafil dosage

The recommended starting tadalafil dosage you take to treat your ED will depend on the type of tadalafil tablet you’re taking. It will also depend on your current health as well as your history with erectile dysfunction tablets. 

There are two main types of tadalafil tablets, tadalafil and Tadalafil Daily. Tadalafil Daily usually comes in milder doses because it’s taken every day to keep your system continually supplied with tadalafil. This allows you to get erections when you need them without needing to take a tablet right before sex. 

On the other hand, standard tadalafil tablets are usually available in stronger doses because they are taken on a “when needed” basis rather than every day. Tadalafil is taken about 30 minutes before sex (because it takes around 30 minutes to kick in) and once it takes effect, it works to encourage stronger erections for up to 36 hours.

Below are the recommended tadalafil dosages for tadalafil and Tadalafil Daily. 

Tadalafil Daily typically comes in two doses:

  • Tadalafil Daily 2.5mg

  • Tadalafil Daily 5mg (recommended starting dose)

Tadalafil is usually available in two doses: 

  • Tadalafil 10mg (recommended starting dose)

  • Tadalafil 20 mg

To make it as easy as possible to get the right tadalafil dosage for you, we at Numan offer a free online consultation for tadalafil and Tadalafil Daily (as well as other our other erectile dysfunction treatments). Our clinicians can assess your health and ED treatment history to prescribe the correct dosage for your needs. This takes the guesswork out of wondering which tadalafil dosage might be best for you while allowing you to benefit from the expertise of our clinicians at the same time.

How long does tadalafil last?

Tadalafil remains active in the body for up to 36 hours, meaning you should be able to successfully get an erection whenever you’re aroused during this period. Tadalafil Daily stays active continually so that you can achieve erections without needing to worry about when its effects will run out.

If you’ve never taken ED tablets before, you may be thinking “does that mean I’ll have an erection for 36 hours/continually?” No. Thankfully, tadalafil’s effects only work when you’re sexually aroused, meaning that you will be able to control when you get an erection. 

As far as erectile dysfunction tablets go, many men prefer tadalafil over sildenafil due to its long-lasting effects. In fact, tadalafil lasts nine times longer than sildenafil, giving you plenty of time to enjoy proper intimacy with your partner without feeling like you need to rush. 

What’s the difference between tadalafil and Tadalafil Daily?

Tadalafil and Tadalafil Daily are both able to encourage stronger erections and they are both clinically proven to be safe and effective treatments for erectile dysfunction.

There are a few differences between the two, however, that might influence your decision to choose one over the other. As they are both effective, your decision is likely to boil down to which suits your preferences and lifestyle more.
