Fildena 100 mg contains sildenafil citrate 100 mg and is marketed in several dosage forms or variants.  100 mg is the maximum recommended single dose for erectile dysfunction in standard sildenafil prescribing guidance. Do not combine different Fildena variants. Never take sildenafil with nitrate medicines or recreational nitrites (poppers), because blood pressure can drop dangerously. Use it under medical guidance. One clarification: Are you interested in the different physical forms (tablet, chewable, softgel and sublingual), or in all Fildena 100 mg brand variants available in India? Fildena 100 mg is a medication containing Sildenafil Citrate 100 mg, commonly used for the treatment of erectile dysfunction (ED) in adult men. It belongs to a class of medicines known as phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection suitable for sexual activity. Fildena 100 mg is generally taken orally with water, approximately 30–60 minutes before planned sexual activity. Its effects may last for around 4–5 hours, although individual responses can vary. It does not increase sexual desire and requires sexual stimulation to work. Common side effects may include headache, facial flushing, nasal congestion, dizziness, indigestion and visual disturbances. Fildena 100 mg should only be used under medical supervision. It must not be taken with nitrate-containing medications or recreational nitrites due to the risk of a dangerous drop in blood pressure. The recommended dose should not be exceeded, and individuals with cardiovascular conditions should consult a healthcare professional before use.
