Tadalafil is prescribed for treating erectile dysfunction and prostate enlargement by increasing blood flow during sexual stimulation, thereby assisting in achieving and maintaining an erection. Additionally, it is indicated for managing pulmonary arterial hypertension (PAH).
Tadalafil operates by inhibiting phosphodiesterase type 5 (PDE5), resulting in the relaxation of blood vessels, which enhances blood flow to the penis when sexually stimulated.
Frequent side effects may include headaches, digestive issues, muscle discomfort, back pain, nasal congestion, and flushing. Should these side effects persist or worsen, please consult your doctor for further guidance.
Tadalafil typically begins to take effect within 30 to 60 minutes after ingestion, with effects potentially lasting up to 36 hours, providing a wide window for intimate moments.
The recommended initiation dose for erectile dysfunction is generally 10 mg, to be taken as needed prior to sexual activity. Based on effectiveness and tolerability, adjustments to the dosage may be made by your healthcare provider.
