The common side effects of taking tadalafil

By Duncan Fisher

Tadalafil has been available for a long time, and has been well studied. Overall, it has shown itself to be an effective and generally well-tolerated for erectile dysfunction.

The active ingredient in tadalafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works much like sildenafil does, by helping to relax and open up the blood vessels in your penis, allowing blood to flow in when you’re sexually aroused, inducing a stronger and longer-lasting erection.

Like any medication, however, tadalafil can sometimes cause side effects. Not everybody will experience them, and most of the side effects reported with tadalafil are fairly mild.

The bottom line

There are rare reports of more serious adverse effects and allergic reactions that may have been related to tadalafil use. There are also certain conditions and which make tadalafil inappropriate, unsuitable or unsafe to take. This also goes for certain other medications that can interact with tadalafil. If you’re in any doubt, you can book in a 30-minute telephone consultation with a UK-based doctor who can answer any of your questions and advise you on next steps.
