Description
Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. It helps relax blood vessels in the penis, improving blood flow during sexual stimulation. It does not increase sexual desire or produce a continuous erection.
What it is used for
Tadalafil 20 mg is authorised for erectile dysfunction in adult men. Its as-needed regimen differs from lower-strength daily tadalafil regimens. Instructions for other tadalafil products or indications should not be transferred to this product.
Side effects
Common effects include headache, indigestion, facial flushing, nasal congestion, back pain and muscle aches.
Seek urgent medical help for an erection lasting more than four hours, sudden vision or hearing changes, or a serious allergic reaction. Chest pain requires immediate assessment: do not take nitrates, and tell the treating clinician when tadalafil was taken. This list is not exhaustive.
Do not combine tadalafil with nitrate medicines, recreational nitrites (“poppers”) or riociguat. Certain heart conditions make it unsuitable. Alpha-blockers, other erectile dysfunction treatments and some antifungal or antibiotic medicines require interaction checks.
Recommended dosage
The usual starting as-needed dose is 10 mg. A prescriber may increase this to 20 mg if necessary. Take at least 30 minutes before sexual activity, no more than once daily. The 20 mg strength is not recommended for continuous daily use. Kidney or liver problems may require a lower dose. Follow the prescription and leaflet.
Storage guidelines
Store in a cool, dark place. Keep out of children’s sight and reach and do not use after expiry.
