Fildena Double 200mg is a potent medication indicated for erectile dysfunction (ED), containing a high dose of sildenafil citrate. The recommended dosage typically involves taking one tablet orally, about 30 minutes to an hour before anticipated sexual activity, with a full glass of water. However, it's crucial to adhere strictly to the prescribed dosage instructions provided by a healthcare professional. Moreover, individuals should avoid exceeding the recommended dosage to prevent potential adverse effects. Precautions include avoiding alcohol consumption, grapefruit juice, and fatty meals, as they may interfere with the medication's efficacy. Consulting a healthcare provider before use is advisable, especially for those with underlying health conditions or taking other medications.
