Description
What Is Tadalafil?
Tadalafil is a prescription medicine used to treat erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). It contains the active ingredient tadalafil, a PDE5 inhibitor that works by improving blood flow in the body. Tadalafil helps men get and maintain an erection during sexual activity and also eases urinary symptoms caused by an enlarged prostate. Some doctors may also prescribe it for pulmonary arterial hypertension under specialist supervision.
What Is Tadalafil Used For?
Tadalafil is prescribed for three main reasons:
— Treats erectile dysfunction by improving blood flow to the penis
— Relieves urinary issues caused by an enlarged prostate (BPH), such as weak stream or frequent urination
— Can help improve blood flow in the lungs in patients with pulmonary arterial hypertension (PAH)
While often known for supporting sexual function, it’s also effective in managing prostate symptoms and certain circulatory conditions.
How Does Tadalafil Work?
Tadalafil relaxes smooth muscles and widens blood vessels to improve circulation. This leads to three key effects:
— In ED, it increases blood flow to the penis when sexually aroused, helping achieve and sustain an erection
— For BPH, it relaxes muscles in the bladder and prostate, making it easier to urinate
— In PAH, it lowers blood pressure in the lungs, helping the heart and lungs work more efficiently
Unlike some treatments, Tadalafil only works with sexual stimulation—it doesn’t trigger an erection on its own.
How Should Tadalafil Be Taken?
Follow your doctor’s instructions carefully when taking Tadalafil. Here’s a general guide:
— For erectile dysfunction: Take 1 tablet at least 30 minutes before sexual activity
— Alternatively, some people take a lower-dose tablet daily for continuous support
— For BPH: Usually taken once daily at the same time each day
— Swallow tablets whole with water—can be taken with or without food
— Do not take more than one dose in a 24-hour period
Taking it consistently helps ensure the best results, especially for daily use.
Are There Any Side Effects?
Like all medications, Tadalafil can cause side effects—though most are mild and temporary.
Common side effects:
— Headache
— Indigestion
— Muscle aches or back pain
— Flushing
— Blocked nose
Uncommon or rare side effects:
— Dizziness
— Blurred vision
— Swelling in hands or feet

— Erection lasting more than 4 hours
— Severe allergic reaction (e.g. rash, difficulty breathing)
If any side effects worry you or persist, speak to a GP as soon as possible.
Who Should Avoid Tadalafil?
Tadalafil isn’t suitable for everyone. Avoid using this medication if any of the following apply:
— A history of heart problems, including recent heart attack or stroke
— Severe liver or kidney disease
— Low blood pressure or uncontrolled high blood pressure
— Allergic reaction to tadalafil or any ingredient in the tablet
— Currently taking nitrates or medications for chest pain
— Not recommended for those under 18 or for use by women
Always check with a doctor before starting Tadalafil—especially if you have existing health conditions or take other medications.
How Should It Be Stored?
Keep your tablets safe and effective by storing them correctly:
— Store below 30°C
— Make sure to keep in original packaging to protect from moisture
— Keep out of reach of children
— Don’t use after the expiry date printed on the pack
— Ask a pharmacist how to dispose of unused medicine safely
