Rivastigmine
Reviewed Nov 2026FDA label
Exelon patch / capsAChE/BuChE inhibitor
- Forms
- Patch: 4.6, 9.5, 13.3mg/24h | Cap: 1.5-6mg
- Dose
- Start 4.6mg/24h patch, titrate monthly to 9.5-13.3mg/24h
- MOA
- Inhibits acetyl- and butyrylcholinesterase
Indications
- Mild, moderate, and severe dementia of the Alzheimer's type (oral capsule/solution and transdermal patch)FDA-labeled
- Mild-to-moderate dementia associated with Parkinson's disease (oral capsule/solution and transdermal patch)FDA-labeled
Off-Label Uses
- Dementia with Lewy bodiesOff-label
- Vascular dementia / mixed dementiaOff-label
Mechanism of Action
- Carbamate-class 'pseudo-irreversible' inhibitor of both acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE)
- Forms a covalent carbamylated complex with the enzyme that dissociates slowly, producing inhibition that outlasts plasma drug levels
- Relatively selective for the G1 (monomeric) form of AChE enriched in Alzheimer's-affected brain regions
- Dual AChE/BuChE inhibition postulated to provide additional benefit as BuChE activity increases with disease progression
Full Dosing
Adult / usual
- Oral capsules/solution: initiate 1.5 mg twice daily with food
- Titrate oral dose upward by 1.5 mg BID increments at intervals of ≥2 weeks, to a target maintenance range of 3-6 mg BID (max 6 mg BID)
- Transdermal patch: initiate 4.6 mg/24h once daily to intact skin on upper back, chest, or upper arm, rotating sites
- After ≥4 weeks on 4.6 mg/24h, increase to usual effective dose of 9.5 mg/24h if tolerated
- For Alzheimer's disease only, after ≥4 additional weeks at 9.5 mg/24h, may increase to 13.3 mg/24h
- Only one patch should be worn at a time
- If therapy is interrupted for more than several days, restart at the lowest dose and re-titrate
Contraindications
- Known hypersensitivity to rivastigmine, other carbamate derivatives, or formulation excipients
- Prior allergic contact dermatitis from the rivastigmine transdermal patch
Drug Interactions
- Other cholinesterase inhibitors or cholinergic agonists: additive cholinergic toxicity
- Anticholinergic drugs may antagonize therapeutic effect
- Succinylcholine and similar agents: risk of exaggerated muscle relaxation during anesthesia
- Metoclopramide: concurrent use not recommended due to additive extrapyramidal effects
- Beta-blockers and other bradycardia-inducing drugs: additive risk of bradycardia and syncope
- NSAIDs: increased risk of GI bleeding
Adverse Effects
- Nausea, vomiting, and diarrhea (more frequent with oral formulation than patch)
- Application-site skin reactions with the patch: erythema, pruritus, contact dermatitis
- Anorexia and weight loss
- Dizziness and headache
- Asthenia/fatigue
- Bradycardia and syncope
- Agitation and confusion
Monitoring Parameters
- Weight and nutritional/hydration status, especially during oral titration
- GI tolerability with each dose increase
- Application site for irritation; rotate patch sites
- Heart rate and symptoms of syncope, particularly with sick sinus syndrome or conduction defects
- Adherence to correct patch strength and single-patch use to avoid overdose
- Hepatic and renal function status when initiating in impaired patients
Pregnancy & Lactation
- No adequate, well-controlled studies in pregnant women
- Animal reproduction studies did not demonstrate teratogenicity but showed maternal/fetal toxicity at high, maternally toxic doses
- Use during pregnancy only if potential benefit justifies potential fetal risk
- Unknown whether excreted in human milk; not recommended during breastfeeding given lack of safety data
