Food & lifestyle
Tyrosine-rich foods
MajorSynergy
Foods that contain large amounts of tyramine may precipitate a hypertensive crisis in patients treated with monoamine oxidase inhibitors (MAOIs). The mechanism is inhibition of MAO-A, the enzyme responsible for metabolizing exogenous amines such as tyramine in the gut and preventing them from being absorbed intact. Once absorbed, tyramine is metabolized to octopamine, a substance that is believed to displace norepinephrine from storage granules.
What to do: In general, patients treated with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, procarbazine) should avoid consumption of products that contain large amounts of amines and protein foods in which aging or breakdown of protein is used to increase flavor. These foods include cheese (particularly strong, aged or processed cheeses), sour cream, wine (particularly red wine), champagne, beer, pickled herring, anchovies, caviar, shrimp paste, liver (particularly chicken liver), dry sausage, salamis, figs, raisins, bananas, avocados, chocolate, soy sauce, bean curd, sauerkraut, yogurt, papaya products, meat tenderizers, fava bean pods, protein extracts, yeast extracts, and dietary supplements. Caffeine may also precipitate hypertensive crisis so its intake should be minimized as well. At least 14 days should elapse following discontinuation of MAOI therapy before these foods may be consumed. Specially designed reference materials and dietary consultation are recommended so that an appropriate and safe diet can be planned. Patients should be advised to promptly seek medical attention if they experience potential signs and symptoms of a hypertensive crisis such as severe headache, visual disturbances, difficulty thinking, stupor or coma, seizures, chest pain, unexplained nausea or vomiting, and stroke-like symptoms. Patients should also be counseled not to use MAOIs with alcohol, and to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them.

Conditions
Conditions in which Linezolid needs care, as documented in this source.
Bone Marrow Failure Disorders
MajorReversible myelosuppression, including anemia, leukopenia, pancytopenia and thrombocytopenia, has been reported during postmarketing use of linezolid, although a causal relationship has not been established. Thrombocytopenia was also reported in phase 3 comparator-controlled trials at dosages up to and including 600 mg every 12 hours for up to 28 days, and bleeding events were identified in thrombocytopenic patients in a compassionate use program for linezolid. Therapy with linezolid should be administered cautiously in patients with preexisting blood dyscrasias and in patients receiving concomitant medications that may produce myelosuppression. Complete blood counts should be monitored weekly, particularly if linezolid is administered for longer than 2 weeks. Discontinuation of therapy should be considered in patients who develop or have worsening myelosuppression.

Colitis
MajorClostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.

Cerebrovascular Disorders
ModerateLinezolid is a weak, reversible, nonselective monoamine oxidase inhibitor (MAOI). Nonspecific MAOIs inhibit the breakdown of pressor amines, the accumulation of which can precipitate hypertensive crises. Intracranial hemorrhage and death have been reported with MAOI antidepressants. While adverse effects related to MAOI activity have not been reported with linezolid, the potential for severe hypertension should be considered. Therapy with linezolid should be administered cautiously in patients with cerebro- or cardiovascular disease, pheochromocytoma, or untreated hyperthyroidism. Clinical data are not available concerning the use of linezolid in this population. As a precaution, patients should have their blood pressure monitored during therapy and observed for signs and symptoms of a hypertensive reaction (e.g., occipital headache which may radiate frontally; palpitation; neck stiffness or soreness; nausea or vomiting; perspiration associated with fever or cold, clammy skin; mydriasis; photophobia; constricting chest pain).

Hypertension
ModerateLinezolid should not be administered to patients with uncontrolled hypertension, pheochromocytoma, thyrotoxicosis and/or patients taking any medication that could affect the pressor response unless patients are being monitored for potential increases in blood pressure. Caution and close monitoring are recommended when prescribing this agent to these patients.

Kidney Diseases
ModerateLinezolid is primarily metabolized by the liver and subsequently eliminated by the kidney. The pharmacokinetics of the parent drug are not altered in patients with impaired renal function and, therefore, no dosage adjustments are necessary. However, accumulation of the two primary metabolites may occur in such patients, the amount of which increases with the degree of renal impairment. The clinical significance of metabolite accumulation has not been determined. Therapy with linezolid should be administered cautiously in patients with renal impairment and only if benefits outweigh the potential risks.

Liver Diseases
ModerateLinezolid is primarily metabolized by the liver. The pharmacokinetics of linezolid are not altered in patients with mild to moderate hepatic impairment (Child-Pugh class A or B) and, therefore, no dosage adjustments are necessary. Pharmacokinetic data are not available for patients with severe hepatic impairment. Therapy with linezolid should be administered cautiously in such patients.

Malignant Carcinoid Syndrome
ModerateLinezolid is a weak, reversible, nonselective monoamine oxidase inhibitor (MAOI). Nonspecific MAOIs inhibit the breakdown of pressor amines, including serotonin, and may exacerbate symptoms of the carcinoid syndrome. While adverse effects related to MAOI activity have not been reported with linezolid, the potential for excessive serotonergic effects should be considered. Therapy with linezolid should be administered cautiously in patients with carcinoid syndrome and in patients receiving serotonergic agents. Clinical data are not available concerning the use of linezolid in these populations.

Peripheral Nervous System Diseases
ModeratePeripheral and optic neuropathies have been reported in patients treated with linezolid. If patients experience symptoms of visual impairment, such as changes in visual acuity, changes in color vision, blurred vision, or visual field defect, prompt ophthalmic evaluation is recommended. Visual function should be monitored in all patients taking linezolid for extended periods and in all patients reporting new visual symptoms regardless of length of therapy with linezolid. If peripheral or optic neuropathy occurs, the continued use of linezolid in these patients should be weighed against the potential risks.
