Cenforce Soft contains sildenafil, permanent discontinuation should be considered when a clinician determines that continued use is unsafe or when a serious adverse reaction occurs. Important reasons to stop and seek medical advice include: Sudden vision loss in one or both eyes — sildenafil should be stopped and medical care sought promptly. Sudden hearing loss or significant hearing decrease — stop the medicine and seek prompt medical attention. An erection lasting more than 4 hours — this is an emergency requiring immediate treatment because prolonged erections can cause permanent damage. A serious allergic reaction to sildenafil or an ingredient. A newly identified contraindication, such as use of nitrate medicines or certain guanylate-cyclase stimulators such as riociguat. Cardiovascular problems that make ***** activity unsafe, where a doctor determines that sildenafil should no longer be used. For ordinary side effects such as headache, flushing, or indigestion, permanent discontinuation isn't automatically necessary; a clinician can decide whether adjusting treatment or using an alternative is appropriate. If you mean whether Cenforce Soft can simply be stopped without tapering, sildenafil generally does not require tapering because it is an as-needed medicine.
