Modula Tablet contains Tadalafil (5mg), a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH) in men. Tadalafil increases blood flow to the penis during sexual arousal, aiding in achieving and maintaining an erection, and also relaxes muscles in the prostate and bladder to help relieve BPH symptoms. Common side effects include headache, flushing, back pain, and indigestion. The tablet can be taken once daily, providing continuous treatment, or as needed before sexual activity. It is crucial to follow the prescribed dosage and avoid taking it with nitrates or certain other medications. Consult a healthcare provider for any severe or persistent side effects or if an erection lasts longer than 4 hours (priapism).
