Fildena dosage (a brand of sildenafil citrate, used for erectile dysfunction) depends on several factors like your health status, age, severity of ED, and other medications. Here’s a step‑by‑step guide: Understand the Available Strengths Fildena comes in multiple strengths: 25 mg – usually for older men, those sensitive to sildenafil, or with mild ED. 50 mg – standard starting dose for most adults. 100 mg – maximum recommended dose; only if lower doses are not effective and tolerated well. Start Low, Increase If Needed Most doctors start at 50 mg for Fildena without serious health issues. If 50 mg is too strong or causes side effects (headache, flushing, dizziness), reduce to 25 mg. If 50 mg is not effective, after consulting your doctor, you may try 100 mg. Never exceed 100 mg in 24 hours.  Consider Your Health Conditions Heart problems or low/high blood pressure: lower doses are safer. Kidney or liver disease: may require dose adjustment. Age over 65: usually safer to start at 25–50 mg. Other medications: especially nitrates or alpha‑blockers — sildenafil is contraindicated with nitrates.   Timing and Use Take 30–60 minutes before ****** activity. Works best on an empty stomach; high-fat meals may delay effect. ****** stimulation is required — it does not cause automatic erections. Only one dose in 24 hours is recommended.   Monitor Side Effects Mild: headache, flushing, dizziness, nasal congestion, upset stomach Severe (seek medical help immediately): erection lasting >4 hours, chest pain, sudden vision/hearing loss
