Sildenafil is a widely prescribed medication primarily used to treat erectile dysfunction. While it can be an effective treatment, understanding the appropriate dosage is crucial for your health and safety. Many patients have questions about how much is too much and what risks are associated with higher doses.
The medication works by improving blood flow, which helps manage erectile dysfunction and pulmonary arterial hypertension. However, taking more than the recommended amount can lead to potentially dangerous complications.
Doctors typically prescribe sildenafil in carefully calculated doses based on individual patient needs. For erectile dysfunction, the standard starting dose is 50 mg, taken approximately one hour before sexual activity. The maximum recommended daily dose is 100 mg.
Several key factors determine the appropriate sildenafil dosage for an individual:
Age
Overall health condition
Existing medical conditions
Other medications being taken
Severity of erectile dysfunction
Taking too much sildenafil can result in serious side effects, including:
Severe headaches
Sudden vision changes
Hearing loss
Prolonged and painful erections
Cardiovascular complications
Flushing
Dizziness
Hypotension

Foods to improve erectile dysfunction can complement medical treatments. However, medication should always be taken exactly as prescribed. Never adjust your dosage without consulting a healthcare professional.
Most patients experience effects within 30-60 minutes of taking the medication.
Consult your doctor. Daily use depends on your specific health condition and medical history.
Seek immediate medical attention if you experience severe side effects or an overdose.
Erectile dysfunction treatments vary. Your doctor can recommend alternatives if sildenafil isn't suitable.
Typically, effects last 4-5 hours, though this can vary by individual.
Understanding sildenafil dosage is critical for safe and effective treatment. Always follow your healthcare provider's guidance and never exceed recommended limits.
