Hi, Rivastigmine is a medication that is used to treat the symptoms of dementia, including Alzheimer s disease. It works by increasing the levels of certain chemicals in the brain that are involved in memory, thinking, and reasoning. The length of time that someone should take Rivastigmine capsules depends on the severity of their dementia and how they respond to the medication. In some cases, people may need to take Rivastigmine for many years, while in other cases, they may be able to stop taking the medication after some time. It is important to talk to your doctor about whether or not you should continue taking Rivastigmine capsules. Your doctor will be able to evaluate your condition and determine whether or not the medication is still appropriate for you. They may also want to adjust your dosage or switch you to a different medication if necessary. Overall, it is important to follow your doctor s instructions regarding your medication and to never stop taking a prescription medication without consulting your doctor first.
