Interactions between your drugs

Moderate

chlorpheniramine HYDROcodone

Applies to: Uni Tuss HC (chlorpheniramine / hydrocodone / phenylephrine) and Uni Tuss HC (chlorpheniramine / hydrocodone / phenylephrine)

MONITOR: Central nervous system- and/or respiratory-depressant effects may be additively or synergistically increased in patients taking multiple drugs that cause these effects, especially in elderly or debilitated patients. Sedation and impairment of attention, judgment, thinking, and psychomotor skills may increase.

MANAGEMENT: During concomitant use of these drugs, patients should be monitored for potentially excessive or prolonged CNS and respiratory depression. Cautious dosage titration may be required, particularly at treatment initiation. Ambulatory patients should be counseled to avoid 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.

Moderate

desmopressin HYDROcodone

Applies to: Stimate (desmopressin) and Uni Tuss HC (chlorpheniramine / hydrocodone / phenylephrine)

MONITOR: Coadministration with opiates may increase the plasma concentrations and pharmacologic effects of oral desmopressin. The risk of water intoxication and/or hyponatremia may be increased. In 18 healthy subjects, loperamide 4 mg given at 24 hours, 12 hours, and 1 hour before a single 400 mcg oral dose of desmopressin increased the peak plasma concentration (Cmax) of desmopressin by 2.3-fold and its systemic exposure (AUC) by 3.1-fold. Pretreatment with loperamide also increased the median time to reach peak desmopressin concentration (Tmax) from 1.3 to 2 hours, but did not affect the terminal elimination half-life. Although not investigated, other opiates may interact similarly with desmopressin by slowing gastrointestinal motility. In addition, some opiate analgesics such as fentanyl, meperidine, morphine, oxycodone, and tramadol have been associated with reports of hyponatremia, sometimes secondary to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). These effects may be additive with those of desmopressin and probably stem from agonist action on morphinic receptors, resulting in increased release of antidiuretic hormone.

MANAGEMENT: Caution is recommended if desmopressin is used in combination with opiates. Serum electrolytes, especially sodium, as well as BUN and creatinine should be monitored regularly. Patients should be advised to seek immediate medical attention if they develop early signs and symptoms of water intoxication or hyponatremia such as anorexia, nausea, vomiting, drowsiness, lethargy, weakness, listlessness, headache, confusion, difficulty concentrating, memory impairment, anuria, and weight gain. Early treatment may help prevent progression to seizure, coma, respiratory arrest, and death.

Drug and food interactions

Major

HYDROcodone food

Applies to: Uni Tuss HC (chlorpheniramine / hydrocodone / phenylephrine)

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including hydrocodone. 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.

GENERALLY AVOID: Consumption of alcohol while taking some sustained-release formulations of hydrocodone may cause rapid release of the drug, resulting in high systemic levels of hydrocodone that may be potentially lethal. Alcohol apparently can disrupt the release mechanism of some sustained-release formulations. In study subjects, the rate of absorption of hydrocodone from an extended-release formulation was found to be affected by coadministration with 40% alcohol in the fasted state, as demonstrated by an average 2.4-fold (up to 3.9-fold in one subject) increase in hydrocodone peak plasma concentration and a decrease in the time to peak concentration. Alcohol also increased the extent of absorption by an average of 1.2-fold (up to 1.7-fold in one subject).

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of hydrocodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of hydrocodone by certain compounds present in grapefruit. Increased hydrocodone concentrations could conceivably increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.

MANAGEMENT: Patients taking sustained-release formulations of hydrocodone should not consume alcohol or use medications that contain alcohol. In general, potent narcotics such as hydrocodone should not be combined with alcohol. Patients should also avoid consumption of grapefruit or grapefruit juice during treatment with hydrocodone.

chlorpheniramine food

Applies to: Uni Tuss HC (chlorpheniramine / hydrocodone / phenylephrine)

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.

Moderate

phenylephrine food

Applies to: Uni Tuss HC (chlorpheniramine / hydrocodone / phenylephrine)

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.

Minor

desmopressin food

Applies to: Stimate (desmopressin)

Food may decrease the rate and extent of absorption of desmopressin following oral administration. In 16 healthy, nonsmoking volunteers, administration of a single 400 mcg oral dose of desmopressin concomitantly with a standardized meal (27% fat) resulted in a 52% decrease in the peak plasma concentration (Cmax) of desmopressin and a 43% decrease in systemic exposure (AUC) compared to administration in the fasting state. The Cmax and AUC were still reduced by 46% and 41%, respectively, when desmopressin was administered 1.5 hours after eating. Both feeding regimens prolonged the time to reach peak plasma concentration (Tmax) from 1 hour to 1.5 hours. However, the pharmacodynamic effects of desmopressin were not affected as assessed by urine volume and osmolality for at least 4 hours postdose. The degree of antidiuresis was similar in the absence of food and when the drug was taken with or 1.5 hours after eating. These findings would suggest a fairly minor clinical impact of the interaction in most patients, especially since oral desmopressin is intended for administration at bedtime. Nevertheless, the possibility of food effects should be considered before increasing the dose whenever a diminution of effect is noted. A significant interaction is not expected to occur with the sublingual formulation, since absorption occurs primarily in the oral mucosa, pharynx, and esophagus.

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.
