Taking sildenafil 100 mg daily is generally not recommended. This is the maximum standard dose and is designed for 'on-demand' use, rather than daily consumption. Taking it every day can increase your risk of side effects, such as headaches, flushing, dizziness, or a sudden drop in blood pressure. If you feel you need daily support for sexual performance, please consult a healthcare professional. They can evaluate your overall health and might suggest safer, low-dose daily alternatives specifically designed for everyday use, such as daily low-dose tadalafil. A doctor can help find the safest and most effective plan for you.
