Edit list (add/remove drugs)

Interactions between your drugs

Moderate

bromocriptine nitroglycerin

Applies to: Parlodel (bromocriptine) and Rectiv (nitroglycerin)

GENERALLY AVOID: Ergot alkaloids, by causing vasoconstriction, may theoretically antagonize the effects of nitrates. In addition, nitrates may increase splanchnic blood flow, resulting in decreased first-pass metabolism of dihydroergotamine and increased bioavailability.

MANAGEMENT: This combination should generally be avoided. Ergot alkaloids are considered contraindicated in patients with ischemic heart disease.

Drug and food interactions

Moderate

bromocriptine food

Applies to: Parlodel (bromocriptine)

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

nitroglycerin food

Applies to: Rectiv (nitroglycerin)

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

Moderate

bromocriptine food

Applies to: Parlodel (bromocriptine)

MONITOR: Nicotine may cause vasoconstriction in some patients and potentiate the ischemic response to ergot alkaloids.

MANAGEMENT: Caution may be advisable when ergot alkaloids are used in combination with nicotine products. Patients should be advised to seek immediate medical attention if they experience potential symptoms of ischemia such as coldness, pallor, cyanosis, numbness, tingling, or pain in the extremities; muscle weakness; severe or worsening headache; visual disturbances; severe abdominal pain; chest pain; and shortness of breath.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
