When used correctly, Fildena 200mg can be an effective treatment for erectile dysfunction, especially for those who require a higher dosage for improved results. Always follow your doctor’s instructions carefully and never exceed the recommended dose to avoid potential risks. Fildena 200mg is typically prescribed for men with moderate to severe erectile dysfunction who need a higher dose to achieve the desired effect. However, this high dose is usually not recommended as the first treatment, especially for those new to erectile dysfunction medications. Fildena 200mg usually starts working within 30 to 60 minutes after ingestion and can remain effective for about 4 to 6 hours. During this time, you will need sexual arousal for the medication to work effectively.
