Rivastigmine helps to reduce symptoms of dementia such as memory loss, confusion, and problems with thinking and reasoning in Alzheimer's disease (a progressive disease which destroys memory and other important mental functions) or in Parkinson's disease (a brain disease that affects movement).
Rivastigmine cannot cure Alzheimer's or Parkinson's disease, but it can improve the quality of life for people who have these illnesses.
Take Rivastigmine exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
Always take Rivastigmine with food. You may take it immediately after a meal. Try to take it at the same time each day.
If you are taking the oral capsule, swallow it whole with a glass of water.
If you are using the oral solution, use the oral dosing syringe provided to draw out the dose from the bottle. The solution may be swallowed directly from the syringe. To make it easier to swallow, you may choose to mix it with a small glass of cold fruit juice or a fizzy drink. However, do make sure the solution is taken within 4 hours of mixing. Do not leave the medicine to stand after you have mixed it.
Rivastigmine must be taken regularly for it to be effective. Continue taking Rivastigmine even when there are signs of improvement which can take a few weeks for you to notice. Do not stop taking Rivastigmine unless instructed by the doctor.
Take the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and return to the normal dosing schedule.
DO NOT double a dose under any circumstances.
If Rivastigmine has been missed for more than a few days, ask the doctor before restarting it.
