If you mean where/how should Fildena Double 200 mg be taken to get a rapid effect  Fildena Double 200 mg contains sildenafil 200 mg (a PDE-5 inhibitor). It is a very high-strength sildenafil product, and doses this high are generally considered above the usual recommended ED dosing range, so it should only be used if specifically advised by a healthcare professional. It is taken by mouth (orally) with water — not under the tongue, not injected, and not applied anywhere else. Sildenafil usually works faster when taken on an empty stomach or after a light meal. A heavy/fatty meal can delay the effect. It generally needs ***** stimulation to produce an erection; it does not create an automatic erection. Because 200 mg is a high dose, taking it for a “stronger” or “faster” effect can increase the risk of side effects such as severe headache, dizziness, low blood pressure, vision changes, and prolonged erection. If you tell me your age, ED severity (mild/moderate/severe), and whether sildenafil 50 or 100 mg worked before, I can help judge whether Fildena Double 200 mg is likely to be useful or unnecessarily high for you.
