Fildena 50 every day? Not automatically. Sildenafil 50 mg is generally intended to be taken when needed, rather than as a routine daily medicine. The recommended maximum frequency for erectile dysfunction is once in 24 hours, but that does not mean daily use is suitable for everyone. Fildena 50  If you have sex occasionally: It is generally taken about 1 hour before sexual activity, if your doctor confirms it is suitable for you. If you want it every day: Consult a doctor first. Daily tadalafil is an alternative that may be more appropriate for frequent sexual activity. Avoid sildenafil completely with nitrate medicines used for chest pain, and check with a doctor if you have heart disease, low blood pressure, or take medicines that interact with it. One important point: Fildena is a branded product, so verify its ingredients and source before using it regularly.
