Tadaga 5 mg, which contains tadalafil, is used primarily to treat erectile dysfunction by enhancing blood flow to the penis. Before using it, consult your doctor, especially if you have heart, liver, or kidney issues. Avoid alcohol and grapefruit juice, as they can interfere with the medication’s effects. Take only one tablet per day, and do not mix it with other ED drugs or nitrates. Possible side effects include headache, flushing, indigestion, and muscle pain. It's effective only with sexual stimulation and should not be taken recreationally. Always follow your healthcare provider’s dosage instructions and report any adverse reactions.
