How to Administer Rivastigmine

Take Rivastigmine exactly as prescribed by your healthcare provider. For oral forms (capsules or solution), take the medication with food to minimize the risk of stomach upset. If using the Rivastigmine patch, apply it to clean, dry, and hairless skin on your back, upper arm, or chest. Be sure to rotate the application site daily to prevent skin irritation. Never cut the patch. If you miss a dose, take it as soon as you remember. If it is close to your next scheduled dose, skip the missed dose and continue with your regular schedule. Do not double your dose to make up for a missed one.

Adverse Reactions and Side Effects of Rivastigmine

As with any medication, Rivastigmine and the Rivastigmine patch can cause side effects, which may range from mild and manageable to more severe.
