Serious Warnings

Known Drug Interactions

7 DRUG INTERACTIONS Concomitant use with metoclopramide, beta-blockers, or cholinomimetic and anticholinergic drugs is not recommended (7.1, 7.2, 7.3) 7.1 Metoclopramide Due to the risk of additive extrapyramidal adverse reactions, the concomitant use of metoclopramide and rivastigmine tartrate is not recommended.

Mechanism: Both drugs can cause similar side effects related to muscle control and movement. Taking them together increases the risk of developing shaky movements or muscle stiffness.

7.3 Beta-blockers Additive bradycardic effects resulting in syncope may occur when rivastigmine tartrate is used concomitantly with beta-blockers, especially cardioselective beta-blockers (including atenolol).

Mechanism: Both of these medicines can slow your heart rate. Taking them at the same time might cause your heart to beat too slowly or make you faint.

7.2 Cholinomimetic and Anticholinergic Medications Rivastigmine tartrate may increase the cholinergic effects of other cholinomimetic medications and may also interfere with the activity of anticholinergic medications (e.g., oxybutynin, tolterodine).

Mechanism: These drugs have opposite effects on the body. Rivastigmine can prevent oxybutynin from working the way it is supposed to.

7.2 Cholinomimetic and Anticholinergic Medications Rivastigmine tartrate may increase the cholinergic effects of other cholinomimetic medications and may also interfere with the activity of anticholinergic medications (e.g., oxybutynin, tolterodine).

Mechanism: Rivastigmine works against drugs like tolterodine. This means tolterodine might not work as well when taken with rivastigmine.
