Can I eat sildenafil again if it's ineffective

If taking sildenafil does not take effect, it is usually not recommended to repeat the medication in the short term. The efficacy of sildenafil may be affected by factors such as drug dosage, timing, and individual differences. It is recommended to adjust the medication regimen under the guidance of a doctor. Sildenafil is a phosphodiesterase 5 inhibitor that works under sexual stimulation conditions. Some patients may experience poor drug absorption due to fasting, alcohol consumption, or high-fat diet affecting drug absorption. Psychological factors such as anxiety or lack of partner cooperation can also reduce drug sensitivity. First time users may have insufficient dosage, but increasing the dosage without authorization may cause adverse reactions such as headaches and facial flushing.

In a few cases, basic diseases such as diabetes and cardiovascular disease will lead to poor drug response. Long term use of nitrate ester drugs is strictly prohibited in combination with sildenafil. Patients with penile vascular disease or nerve damage may not respond to medication at all, and the cause should be determined through penile ultrasound and other examinations. There are very few patients in clinical practice who are naturally resistant to this drug. When ineffective medication occurs, specific circumstances should be recorded, including medication time, dietary status, and physical reactions, and timely feedback should be given to a urologist or cardiovascular specialist. Doctors may recommend replacing similar medications such as Tadalafil or using a vacuum negative pressure device in combination. Improving lifestyle habits such as controlling blood pressure and reducing weight can help enhance drug efficacy. It is absolutely prohibited to repeat or overdose medication within 24 hours to avoid inducing severe hypotension. Erectile dysfunction involves multiple physiological and psychological factors, and individualized treatment plans need to be developed through professional evaluation.
