Minor
Contraindicated (7)
- fezolinetant

Serious - Use Alternative (7)
- abametapir
abametapir will increase the level or effect of caffeine by affecting hepatic enzyme CYP1A2 metabolism. Avoid or Use Alternate Drug. For 2 weeks after abametapir application, avoid taking drugs that are CYP1A2 substrates. If not feasible, avoid use of abametapir.
- bupropion

- dipyridamole
caffeine decreases effects of dipyridamole by pharmacodynamic antagonism. Contraindicated.
- givosiran
givosiran will increase the level or effect of caffeine by affecting hepatic enzyme CYP1A2 metabolism. Avoid or Use Alternate Drug.

- iobenguane I 131
caffeine will decrease the level or effect of iobenguane I 131 by Other (see comment). Avoid or Use Alternate Drug. Based on the mechanism of action of iobenguane, drugs that reduce catecholamine uptake or that deplete catecholamine stores may interfere with iobenguane uptake into cells, and thus, reduce iobenguane efficacy. Discontinue interfering drugs for at least 5 half-lives before administration of either the dosimetry or an iobenguane dose. Do not administer these drugs until at least 7 days after each iobenguane dose.
- ozanimod
ozanimod increases toxicity of caffeine by sympathetic (adrenergic) effects, including increased blood pressure and heart rate. Avoid or Use Alternate Drug.
