Interactions between Cholestyramine Light and Gabapentin

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Anemia.

Bile acid sequestrants may interfere with the absorption of folic acid and fat soluble vitamins such as A, D, and K. Chronic use of bile acid sequestrants may cause increased bleeding tendency due to hypoprothrombinemia associated with vitamin K deficiency. Anemia may also occur due to reduced serum or red blood cell folate. Supplementation with oral vitamins and/or folate should be considered during prolonged therapy with bile acid sequestrants, particularly in patients with preexisting vitamin and/or folate deficiencies, anemia, or a bleeding diathesis.

The cholestyramine in Cholestyramine Light has a major potential interaction with Biliary Obstruction.

The use of bile acid sequestrants is contraindicated in patients with complete biliary obstruction where bile is not secreted into the intestine. These agents adsorb and combine with bile acids in the intestine to form an insoluble complex that is excreted in the feces, resulting in partial removal of bile acids from the enterohepatic circulation. Bile acid sequestrants are ineffective if bile does not reach the intestine.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Coagulation Defects and Disorders.

Bile acid sequestrants may interfere with the absorption of folic acid and fat soluble vitamins such as A, D, and K. Chronic use of bile acid sequestrants may cause increased bleeding tendency due to hypoprothrombinemia associated with vitamin K deficiency. Anemia may also occur due to reduced serum or red blood cell folate. Supplementation with oral vitamins and/or folate should be considered during prolonged therapy with bile acid sequestrants, particularly in patients with preexisting vitamin and/or folate deficiencies, anemia, or a bleeding diathesis.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Constipation.

The use of bile acid sequestrants may produce or worsen preexisting constipation. Constipation associated with these agents may aggravate hemorrhoids. Therapy with bile acid sequestrants should be administered cautiously in patients with preexisting constipation, hemorrhoids, or symptomatic coronary artery disease. The dosage should be increased very gradually according to manufacturer guidelines to minimize the risk of fecal impaction, and patients should be encouraged to increase fluid and fiber intake. Occasional use of a stool softener may also be indicated. If constipation worsens or develops during therapy, or the desired therapeutic response is not achieved at the maximum recommended daily dosage, combination therapy or an alternative agent should be considered.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Dehydration.

Bile acid sequestrants are chloride forms of anion exchange resins and may produce hyperchloremic acidosis with chronic use. Therapy with bile acid sequestrants should be administered cautiously in patients who may be particularly susceptible, including children or smaller patients and patients with renal impairment or volume depletion.

Gabapentin has a moderate potential interaction with Depression.

Antiepileptic drugs (AEDs) have been associated with an increased risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Pooled analyses of 199 placebo-controlled clinical studies involving the use of 11 different AEDs showed that patients receiving AEDs had approximately twice the risk of suicidal thinking or behavior compared to patients receiving placebo. AEDs should be administered cautiously in patients with depression or other psychiatric disorders; phentermine-topiramate should be avoided in patients with history of suicidal attempts or active suicidal ideation. The risk of suicidal thoughts and behavior should be carefully assessed against the risk of untreated illness, bearing in mind that epilepsy and many other conditions for which AEDs are prescribed are themselves associated with morbidity and mortality and an increased risk of suicidal thoughts and behavior. Patients, caregivers, and families should be alert to the emergence or worsening of signs and symptoms of depression, any unusual changes in mood or behavior, or the emergence of suicidal thoughts or behavior. If patients have symptoms of suicidal ideation or behavior, a dosage reduction or treatment discontinuation should be considered.

Gabapentin has a major potential interaction with Drug Dependence.

Anxiolytic, sedative, and hypnotic agents have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages, and abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance, overdosage can still produce respiratory depression and death. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously and for as brief a period as possible. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with these agents. In addition, it may be prudent to refrain from dispensing large quantities of medication to such patients. After prolonged use or if dependency is suspected, withdrawal of medication should be undertaken gradually using a dosage-tapering schedule.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Folic Acid/Cyanocobalamin Deficiency.

Bile acid sequestrants may interfere with the absorption of folic acid and fat soluble vitamins such as A, D, and K. Chronic use of bile acid sequestrants may cause increased bleeding tendency due to hypoprothrombinemia associated with vitamin K deficiency. Anemia may also occur due to reduced serum or red blood cell folate. Supplementation with oral vitamins and/or folate should be considered during prolonged therapy with bile acid sequestrants, particularly in patients with preexisting vitamin and/or folate deficiencies, anemia, or a bleeding diathesis.

Gabapentin has a moderate potential interaction with Hemodialysis.

Gabapentin is removed by hemodialysis and should be administered after dialysis.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Hemorrhoids.

The use of bile acid sequestrants may produce or worsen preexisting constipation. Constipation associated with these agents may aggravate hemorrhoids. Therapy with bile acid sequestrants should be administered cautiously in patients with preexisting constipation, hemorrhoids, or symptomatic coronary artery disease. The dosage should be increased very gradually according to manufacturer guidelines to minimize the risk of fecal impaction, and patients should be encouraged to increase fluid and fiber intake. Occasional use of a stool softener may also be indicated. If constipation worsens or develops during therapy, or the desired therapeutic response is not achieved at the maximum recommended daily dosage, combination therapy or an alternative agent should be considered.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Ischemic Heart Disease.

If constipation worsens or develops during therapy, or the desired therapeutic response is not achieved at the maximum recommended daily dosage, combination therapy or an alternative agent should be considered.

The cholestyramine in Cholestyramine Light has a moderate potential interaction with Phenylketonuria.

Questran Light and LoCholest Light (brands of cholestyramine) contain 16.8 mg and 22.4 mg of phenylalanine, respectively, per each dose. Flavored Colestid (brand of colestipol) contains 18.2 mg of phenylalanine per each 7.5-gram dose. WELCHOL (brand name of colesevelam) for Oral Suspension contains 13.5 mg phenylalanine per 1.875 gram dose and 27 mg phenylalanine per 3.75 gram dose. The phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics). Regular Colestid, Questran and LoCholest do not contain phenylalanine.

Gabapentin has a moderate potential interaction with Psychosis.

Gabapentin has a major potential interaction with Renal Dysfunction.

Gabapentin is primarily eliminated unchanged by the kidney. Therapy with gabapentin should be administered cautiously in patients with impaired renal function. Dosage adjustments and titration should be made in accordance with product package labeling and individual patient response.
