Tadalafil: Uses, Dosage, and What to Expect
Tadalafil treats erectile dysfunction and benign prostate hyperplasia. Costs from $10 to $60 per dose depending on strength and pharmacy. Works within 30 minutes; effects last up to 36 hours.
Tadalafil is a phosphodiesterase-5 inhibitor used to treat erectile dysfunction and benign prostate hyperplasia in men. It's the active ingredient in brand-name medications including Cialis.
How it works
Tadalafil relaxes smooth muscle tissue in the penis and bladder, increasing blood flow and allowing erections in response to sexual stimulation. For prostate symptoms, it reduces urinary urgency and frequency.
Dosage and timing
For erectile dysfunction, standard doses run from 2.5mg to 20mg, taken 30 minutes to 2 hours before sexual activity. Effects typically last 24 to 36 hours. Lower daily doses (2.5mg to 5mg) are available for continuous use.
For benign prostate hyperplasia, the usual dose is 5mg once daily.
Cost
Generic tadalafil ranges from $10 to $60 per dose at most US pharmacies, depending on strength and quantity purchased. Brand-name Cialis typically costs significantly more without insurance coverage.
Side effects
Common effects include headache, muscle aches, indigestion, and flushed skin. Serious side effects are rare but may include sudden vision or hearing loss, or priapism (erection lasting more than 4 hours).
Important notes
Do not take tadalafil with nitrate medications. Discuss all current medications with a prescriber before starting. Alcohol may increase side effects.
