Interactions between your drugs

Moderate

phenelzine porfimer

Applies to: phenelzine and Photofrin (porfimer)

GENERALLY AVOID: Patients exposed to photosensitizing agents at the same time as or in the 30 to 90 days following treatment with porfimer may be at an increased risk of a photosensitivity reaction (e.g., erythema, swelling, pruritus, burning sensations, feeling hot, and/or blisters). These agents have each been individually associated with photosensitivity reactions and may have additive effects if used together. Medicinal products with known phototoxic or photoallergic potential include, but are not limited to, hypericin-containing products (e.g., St. John's Wort), griseofulvin, thiazide diuretics, sulfonylureas, phenothiazines, sulfonamides, quinolones, and tetracyclines. Photosensitivity with porfimer is due to residual drug being present in the skin. Porfimer is cleared from a variety of tissues over 40 to 72 hours after treatment, but organs of the reticuloendothelial system (e.g., liver, spleen), skin and the tumor itself retain the drug for a longer period. Patients treated with porfimer will be photosensitive for at least 30 days and possibly up to 90 days or more for patients with hepatic or severe renal dysfunction. In clinical studies of porfimer, photosensitivity reactions occurred in approximately 20% of cancer patients and 69% of high-grade dysplasia in Barrett's esophagus patients.

MANAGEMENT: Use of photosensitizing agents should be avoided for at least 30 days and maybe up to 90 days or longer after porfimer treatment depending on the patient's hepatic function, renal function, and/or ability to tolerate exposure to sunlight. Following treatment with porfimer, patients should follow measures outlined in the product labeling for light and sun exposure. It is important to counsel patients to expose their skin to ambient indoor light as it is not only safe but will help eliminate porfimer through the skin by a process called "photobleaching." Before exposing skin or eyes to direct sunlight or bright indoor light (e.g., examination lamps, dental lamps, operating room lamps, floodlights, halogen lamps, unshaded light bulbs at close proximity, etc.), patients should test for residual photosensitivity as described in porfimer's product labeling.

Drug and food interactions

Major

phenelzine food

Applies to: phenelzine

CONTRAINDICATED: 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.

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

MANAGEMENT: 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.

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.
