potassium chloride doxylamine

Applies to: potassium chloride, All-Nite Cold (acetaminophen / dextromethorphan / doxylamine / pseudoephedrine)

CONTRAINDICATED: The following interaction does not apply to all products containing potassium chloride, including split dose products used for colon preparation prior to colonoscopy. It is applicable to certain oral solid formulations of potassium chloride used primarily for potassium supplementation, and the prescriber should consult the individual product labeling for more specific information and guidance.

Concomitant use of agents with anticholinergic properties (e.g., antihistamines, antispasmodics, neuroleptics, phenothiazines, skeletal muscle relaxants, tricyclic antidepressants, the class IA antiarrhythmic disopyramide) may potentiate the risk of upper gastrointestinal injury associated with oral solid formulations of potassium chloride. The proposed mechanism involves increased gastrointestinal transit time due to reduction of stomach and intestinal motility by anticholinergic agents, thereby creating a high localized concentration of potassium ions in the region of a dissolving tablet or capsule and increasing the contact time with GI mucosa. Solid formulations of potassium chloride have been associated with upper GI bleeding and small bowel ulceration, stenosis, perforation, and obstruction. Deaths have been reported rarely. In clinical studies, short-term coadministration of wax-matrix or microencapsulated formulations of potassium chloride at high dosages in combination with an anticholinergic agent such as glycopyrrolate resulted in more frequent and more serious endoscopic lesions than potassium therapy alone. However, the lesions were not accompanied by bleeding or epigastric symptoms. Some investigators have suggested a higher risk of upper GI lesions with wax-matrix than microencapsulated formulations, although existing data are limited and conflicting.

MANAGEMENT: The use of certain oral solid formulations of potassium chloride is considered contraindicated in patients receiving agents with anticholinergic properties at sufficient doses to exert anticholinergic effects. A liquid formulation of potassium chloride should be considered. Patients prescribed a solid oral formulation should be advised to discontinue potassium therapy and contact their physician if they experience potential symptoms of upper GI injury such as severe vomiting, abdominal pain, distention, and gastrointestinal bleeding.

Moderate

dextromethorphan doxylamine

Applies to: All-Nite Cold (acetaminophen / dextromethorphan / doxylamine / pseudoephedrine), All-Nite Cold (acetaminophen / dextromethorphan / doxylamine / pseudoephedrine)

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.

Drug and food interactions

Major

acetaminophen food

Applies to: All-Nite Cold (acetaminophen / dextromethorphan / doxylamine / pseudoephedrine)

GENERALLY AVOID: Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.

MANAGEMENT: In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day. However, if acetaminophen is used, these patients should be cautioned not to exceed the recommended dosage (maximum 4 g/day in adults and children 12 years of age or older).

dextromethorphan food

Applies to: All-Nite Cold (acetaminophen / dextromethorphan / doxylamine / pseudoephedrine)

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.

pseudoephedrine food

Applies to: All-Nite Cold (acetaminophen / dextromethorphan / doxylamine / 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.
