Fildena 150 mg contains sildenafil citrate, a high-dose erectile dysfunction (ED) medication. Its use in elderly patients requires special caution because aging can affect drug metabolism, heart function, and kidney/liver clearance. Here’s a detailed explanation: When it can be used After medical evaluation: Elderly patients should only use Fildena 150 mg after a thorough check-up by a healthcare professional. Doctors assess heart health, blood pressure, kidney and liver function, and other medications that might interact with sildenafil. If lower doses are ineffective and safe: Typically, doctors start with lower doses (25–50 mg) in elderly patients due to higher sensitivity and slower drug metabolism. Fildena 150 mg may be considered only if lower doses were ineffective and no contraindications exist. With monitoring: Elderly patients are more prone to side effects such as dizziness, low blood pressure, palpitations, headache, or visual disturbances. Use under close supervision, and dose adjustments may be required. Precautions for elderly patients Avoid if taking nitrates (e.g., for angina) — can cause dangerous drops in blood pressure. Be cautious if the patient has heart disease, kidney or liver impairment, or uncontrolled blood pressure. Avoid combining with certain antifungal, antibiotic, or HIV medications that may interact with sildenafil. Start with the lowest effective dose and increase only if necessary and safe.
