            Contraindicated (6)

            • isocarboxazid

              isocarboxazid increases effects of caffeine by pharmacodynamic synergism. Contraindicated. Risk of acute hypertensive episode.

            • linezolid

            • phenelzine

              phenelzine increases effects of caffeine by pharmacodynamic synergism. Contraindicated. Risk of acute hypertensive episode.

            • procarbazine

              procarbazine increases effects of caffeine by pharmacodynamic synergism. Contraindicated. Caffeine can produce severe hypertensive crises or dangerous cardiac arrhythmias if administered to patients taking a MAOI. All preparations containing caffeine should be used sparingly.

            • selegiline transdermal

              selegiline transdermal increases effects of caffeine by pharmacodynamic synergism. Contraindicated. Risk of acute hypertensive episode.

            • tranylcypromine

              tranylcypromine increases effects of caffeine by pharmacodynamic synergism. Contraindicated. Risk of acute hypertensive episode.

            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

              caffeine increases toxicity of bupropion by unspecified interaction mechanism. Avoid or Use Alternate Drug. May lower seizure threshold; keep bupropion dose as low as possible.

            • 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. Avoid coadministration of sensitive CYP1A2 substrates with givosiran. If unavoidable, decrease the CYP1A2 substrate dosage in accordance with approved product labeling.

            • 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. Because the active metabolite of ozanimod inhibits MAO-B in vitro, there is a potential for serious adverse reactions, including hypertensive crisis. Therefore, coadministration of ozanimod with drugs that can increase norepinephrine or serotonin is not recommended. Monitor for hypertension with concomitant use.

              caffeine decreases effects of regadenoson by pharmacodynamic antagonism. Avoid or Use Alternate Drug. Avoid methylxanthines for 12 hours before regadenoson administration.
