Fildena double 200 mg is a medication commonly used for the treatment of erectile dysfunction. Fildena 100mg helps to improve blood flow to the penis, but it does not induce an automatic erection. Sexual stimulation is still required to achieve an erection. Fildena 100mg should be taken orally with a glass of water, approximately 30 minutes to 1 hour before engaging in sexual activity. Avoid taking it with a heavy or high-fat meal, as it may delay the onset of action. Taking Fildena 150 mg online can have potential side effects and interactions with other medications, so you should consult a healthcare professional before doing so.
