RIVAMER 4.5 mg is a medication containing Rivastigmine Tartrate, a cholinesterase inhibitor used in the symptomatic treatment of mild to moderately severe Alzheimer's disease and dementia associated with Parkinson's disease. Rivastigmine works by inhibiting the breakdown of acetylcholine, a neurotransmitter involved in memory and cognition, thereby improving or stabilizing symptoms related to these conditions. The recommended starting dose is 1.5 mg twice daily, with gradual increases based on patient tolerance, up to a maximum of 6 mg twice daily. It is important to take RIVAMER with food to enhance absorption and reduce gastrointestinal side effects. Patients should be monitored for potential adverse reactions, including nausea, vomiting, and weight loss, especially during dose escalation. Additionally, caution is advised in patients with a history of heart problems, seizures, or respiratory issues. RIVAMER should not be used during pregnancy or breastfeeding unless clearly necessary, and its use is contraindicated in individuals with known hypersensitivity to Rivastigmine or other carbamate derivatives.
