Interactions between your drugs

Moderate

dextromethorphan amphetamine

Applies to: Double-Tussin DM (dextromethorphan / guaifenesin) and amphetamine

MONITOR: Coadministration of amphetamines and amphetamine-like drugs with other agents that also increase serotonin levels or effects, may increase the risk of serotonin syndrome. The exact mechanism by which serotonin levels are increased differs depending on the specific medication(s) involved. Serotonin syndrome is believed to result from the hyperstimulation of postsynaptic 5-HT receptors and while postsynaptic 5-HT1A and 5-HT2A receptors are usually implicated, it is more likely that no single receptor is solely responsible. Clinical data are limited. Serotonin syndrome involving amphetamines has most frequently been reported with the use of MDMA, or ecstasy, an amphetamine derivative with enhanced serotonergic activity over classical amphetamines, which tend to be more dopaminergic. However, case reports of serotonin syndrome involving amphetamines and amphetamine-like drugs have been documented with concomitant use of other serotonergic substances (e.g., selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, monoamine oxidase inhibitors). Abuse and/or overdose may increase the risk of experiencing this adverse effect.

MANAGEMENT: Caution is recommended when amphetamines and amphetamine-like drugs are used with other agents that also increase serotonin levels or effects. Initiating patients with lower doses and ensuring close clinical monitoring for signs and symptoms of serotonin syndrome (e.g., altered mental status, hypertension, restlessness, myoclonus, hyperthermia, hyperreflexia, diaphoresis, shivering, tremor) is advised. Particular caution is recommended when increasing the dosages of these agents. If serotonin syndrome develops or is suspected during the course of therapy, all serotonergic agents should be discontinued immediately, and treatment rendered as indicated.

Drug and food interactions

Moderate

dextromethorphan food

Applies to: Double-Tussin DM (dextromethorphan / guaifenesin)

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.

amphetamine food

Applies to: amphetamine

GENERALLY AVOID: Alcohol may potentiate the cardiovascular effects of amphetamines. The exact mechanism of interaction is unknown. In one study, concurrent administration of methamphetamine (30 mg intravenously) and ethanol (1 gm/kg orally over 30 minutes) increased heart rate by 24 beats/minute compared to methamphetamine alone. This increases cardiac work and myocardial oxygen consumption, which may lead to more adverse cardiovascular effects than either agent alone. Subjective effects of ethanol were diminished in the eight study subjects, but those of methamphetamine were not affected. The pharmacokinetics of methamphetamine were also unaffected except for a decrease in the apparent volume of distribution at steady state. The interaction was suspected in a case report of a 20-year-old male who experienced retrosternal chest pain shortly after drinking alcohol and taking a double dose of his amphetamine/dextroamphetamine medication (Adderall 15 mg X 2) to stay alert. The patient had no family history of cardiovascular diseases, and his past medical history was remarkable only for ADHD. Prior to the episode, the patient had not taken his medication for weeks and had been drinking whiskey the previous three nights before going to bed. The patient was diagnosed with myocardial infarction likely secondary to amphetamine-induced coronary vasospasm.

MANAGEMENT: Concomitant use of amphetamines and alcohol should be avoided if possible, especially in patients with a history of heart disease.

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.
