Tadalafil Treatments

Tadalafil is an active ingredient used in medicines for erectile dysfunction (ED). It belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors, which help increase blood flow to the penis during sexual stimulation.

One of tadalafil’s distinguishing characteristics is its duration of action, which may extend for up to 36 hours. This does not mean an erection lasts continuously throughout that period. Sexual stimulation is still required for tadalafil to support erectile function.

In the United Kingdom, authorised tadalafil medicines are available in strengths including 2.5mg, 5mg, 10mg and 20mg. Different strengths are intended for different treatment regimens, and the appropriate choice depends on individual medical circumstances.

Tadalafil is the active ingredient in Cialis and various authorised generic medicines. Other tadalafil-containing products are marketed internationally in different strengths and formulations, including oral jelly preparations. These products should not automatically be considered equivalent to medicines authorised in the UK.

Important safety considerations include interactions with nitrate medicines, certain cardiovascular conditions and possible adverse effects such as headache, indigestion, back pain and muscle aches. Medical assessment is recommended before considering treatment.
