linezolid aprocitentan

Applies to: linezolid and aprocitentan

Consumer information for this interaction is not currently available.

MONITOR: Monoamine oxidase inhibitors (MAOIs) may potentiate the hypotensive effect of some medications. MAOIs alone quite commonly produce orthostatic hypotension. This effect may stem from a gradual MAOI-induced accumulation of false neurotransmitters in peripheral adrenergic neurons that have minimal activity at alpha- and beta-adrenergic receptors, resulting in a functional block of sympathetic neurotransmission. The interaction has been reported with the concomitant use of beta-blockers. In one report, a young woman developed marked orthostatic hypotension following the addition of pindolol 2.5 mg three times a day to an existing regimen of tranylcypromine. The pindolol dosage was reduced to 2.5 mg twice a day until her blood pressure stabilized, then slowly increased to 5 mg three times a day.

MANAGEMENT: Caution is advised during coadministration of MAOIs and other medications with hypotensive effects, especially during the first few weeks of treatment. Close monitoring for development of hypotension is recommended. Ambulatory 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.

Drug and food interactions

Major

linezolid food

Applies to: linezolid

During and within two weeks after treatment with linezolid, you must not consume any foods or beverages that are high in tyramine content. Doing so can raise your blood pressure to dangerous levels, a condition known as hypertensive crisis. The condition is potentially fatal and may cause symptoms such as severe headache, confusion, blurred vision, problems with speech or balance, nausea, vomiting, chest pain, convulsions, and sudden numbness or weakness (especially on one side of the body). You should seek immediate medical attention if you have any of these symptoms. Foods that are high in tyramine include, but are not limited to, air dried meats; aged or fermented meats; sausage or salami; pickled herring; anchovies; liver; red wine; beer; aged cheeses, including blue, brick, brie, cheddar, parmesan, romano, and swiss; sour cream; sauerkraut; canned figs; raisins; bananas or avocados (particularly if overripe); soy beans; soy sauce; tofu; miso soup; bean curd; fava beans; or yeast extracts (such as Marmite). You should avoid the use of alcohol while being treated with linezolid, as alcohol may increase some of the nervous system side effects such as dizziness, drowsiness, and difficulty concentrating. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

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.
