Tadalafil 20 mg oral tablets are prescribed for the treatment of benign prostatic hyperplasia (BPH) and erectile dysfunction (ED) [1]. The drug functions by relaxing muscles in the prostate and bladder and increasing blood flow to the penis [1].
What is the difference between Tadalafil 20 mg and other dosages?
Tadalafil is available in various dosages, including 2.5 mg, 5 mg, 10 mg, and 20 mg. The 20 mg dosage is specifically indicated for on-demand treatment of ED and BPH [1]. Lower doses, such as 2.5 mg and 5 mg, are typically prescribed for daily use to manage BPH symptoms or for ED in individuals who prefer daily treatment [2]. The appropriate dosage depends on the condition being treated and individual patient factors, as determined by a healthcare provider [1, 2].
How does Tadalafil work to treat BPH?
Tadalafil treats BPH by relaxing the smooth muscles in the prostate gland and bladder neck [1]. This relaxation eases the obstruction of the urinary flow, thereby alleviating symptoms such as frequent urination, urgency, and difficulty starting or stopping the urine stream [1, 3]. By improving urine flow, it helps to relieve the discomfort associated with an enlarged prostate [1].
What are the potential side effects of Tadalafil 20 mg?
Common side effects of Tadalafil 20 mg can include headache, indigestion, back pain, muscle aches, flushing, and nasal congestion [1]. These side effects are usually mild to moderate and tend to resolve on their own. More serious, though less common, side effects can occur and warrant immediate medical attention. These may include a sudden loss of vision in one or both eyes, or a sudden decrease or loss of hearing [1].
