Interactions between your drugs

Major

codeine selegiline

Applies to: Lortuss EX (codeine / guaifenesin / pseudoephedrine) and Selgene (selegiline)

GENERALLY AVOID: Coadministration of monoamine oxidase inhibitors (MAOIs), such as selegiline (an MAO-B inhibitor), with opioid analgesics may result in serotonin syndrome, which is a rare but serious and potentially fatal condition thought to result from hyperstimulation of brainstem 5HT1A receptors. The exact mechanism of interaction is unknown, but may involve additive pharmacodynamic effects resulting from MAOI inhibition of serotonin metabolism. The interaction is unpredictable and has been reported primarily with meperidine or fentanyl and various MAOIs including phenelzine, tranylcypromine, linezolid, moclobemide, and selegiline.

MANAGEMENT: Concomitant use of MAOIs, such as selegiline, with opioid analgesics should generally be avoided. At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with an opioid analgesic. If coadministration is unavoidable, patients should be monitored for signs and symptoms of serotonin syndrome which may include mental status changes such as irritability, altered consciousness, confusion, hallucinations, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea. Some authorities consider the use of selegiline with opioid analgesics to be contraindicated (UK).

pseudoephedrine selegiline

Applies to: Lortuss EX (codeine / guaifenesin / pseudoephedrine) and Selgene (selegiline)

CONTRAINDICATED: Indirect- or mixed-acting sympathomimetic amines may precipitate severe hypertensive reactions and hyperpyrexia in patients treated with monoamine oxidase inhibitors (MAOIs). Death has occurred in some reported cases. The mechanism involves a synergistic sympathomimetic effect due to enhanced norepinephrine storage in adrenergic neurons (MAOI activity) and increased liberation of catecholamines (indirect sympathomimetic activity). Although the interaction has primarily involved nonselective MAOIs, hypertensive crisis has been reported in a patient taking ephedrine with the recommended dosage of a selective MAO-B inhibitor.

MANAGEMENT: In general, indirect- and mixed-acting sympathomimetic agents should not be used concurrently with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, methylene blue, procarbazine). At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with sympathomimetic agents.

Drug and food interactions

Major

selegiline food

Applies to: Selgene (selegiline)

GENERALLY AVOID: 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. Although selegiline is considered a selective inhibitor of MAO-B, the selectivity may not be absolute even at recommended dosages. Rare cases of hypertensive reactions associated with ingestion of tyramine-containing foods have been reported in patients taking the recommended daily oral dose of selegiline. Data for transdermal selegiline indicate that the 6 mg/24 hour dosage may be given safely without dietary restrictions. However, limited data are available for higher dosages.

MANAGEMENT: Patients treated with oral selegiline and transdermal selegiline (greater than 6 mg/24 hour) should preferably 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 selegiline 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 also 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. The recommended dosages of selegiline should not be exceeded, as it can increase the risk of nonselective MAO inhibition and a hypertensive crisis.

codeine food

Applies to: Lortuss EX (codeine / guaifenesin / pseudoephedrine)

GENERALLY AVOID: Ethanol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

MANAGEMENT: Concomitant use of opioid analgesics with ethanol should be avoided.

selegiline food

Applies to: Selgene (selegiline)

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

MANAGEMENT: Patients receiving CNS-active agents should be advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled against driving, operating machinery, or engaging in potentially hazardous activities requiring 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.

pseudoephedrine food

Applies to: Lortuss EX (codeine / guaifenesin / pseudoephedrine)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

MANAGEMENT: Caution is advised if two or more sympathomimetic agents are coadministered. Pulse and blood pressure should be closely monitored.

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.
