Fildena 50 contains sildenafil 50 mg and is being used for erectile dysfunction, it generally can be stopped suddenly without tapering. Sildenafil for ED is normally taken as needed, rather than as a medication that requires gradual dose reduction. Stopping it may simply mean that your underlying erectile difficulties return when you no longer use it; stopping does not typically cause a withdrawal syndrome. If you have Fildena 50 Mg using it regularly and want to stop because it isn't working or is causing side effects, discuss the reason with your clinician. Seek urgent medical attention for chest pain, an erection lasting more than 4 hours, or sudden vision or hearing loss. Also, sildenafil should not be combined with nitrate medicines because of the risk of a dangerous blood-pressure drop.
