Rivamensa 4.6 mg/24 hours transdermal patch (by Daehwa Pharmaceutical) is a once-daily, convenient skin patch delivering Rivastigmine steadily over 24 hours to support cognitive function in mild to moderate Alzheimer’s disease, helping improve memory, awareness, and daily functioning while reducing the gastrointestinal side effects often seen with oral forms; each box contains 30 patches for a full month of continuous therapy, making it a practical, compliance-friendly option for long-term management—however, it must be used strictly under medical supervision, as common risks include nausea, vomiting, dizziness, skin irritation at the patch site, and potential worsening of conditions like bradycardia or gastric ulcers, and improper use (e.g., applying multiple patches or failing to rotate sites) can lead to overdose or serious adverse effects.
