How long does it take for Sildenafil tablets to have a reaction

Sildenafil tablets usually take effect within 30 minutes to 1 hour after taking, and the specific time is affected by individual differences, dietary conditions, medication dosage, and other factors. Sildenafil tablets are a medication used to treat male erectile dysfunction. Its main component, sildenafil, improves erectile function by inhibiting the activity of phosphodiesterase 5, increasing the level of guanosine monophosphate in the corpus cavernosum of the penis, promoting vasodilation. When taken on an empty stomach, the absorption rate of the medication is faster, and the onset time may be shortened to about 30 minutes. If taken with a high-fat diet, the absorption rate may be delayed and it may take an hour or more to take effect. The dosage of medication can also affect the onset time, and most patients can feel the effect within 1 hour at regular doses. In some special cases, the onset time of sildenafil tablets may be prolonged. Elderly patients may experience delayed drug absorption and onset due to slower metabolic rates. Simultaneously taking certain medications such as nitrate esters and antifungal drugs may affect the metabolic process of sildenafil. Patients with severe liver function impairment may experience a decrease in drug clearance rate, which may lead to delayed drug efficacy. In these cases, it is recommended to adjust the medication plan under the guidance of a doctor.

When using sildenafil tablets, attention should be paid to avoiding co administration with nitrate drugs, which may cause severe hypotension. If any discomfort symptoms such as abnormal vision or palpitations occur during medication, seek medical attention promptly. It is recommended to use this medication under the guidance of a doctor and adjust the medication time and dosage according to individual circumstances. Maintaining a healthy lifestyle, moderate exercise, and weight control can help improve erectile function. During medication, excessive alcohol consumption should be avoided to avoid affecting the efficacy of the medication.
