Drug Interaction Report

Tetrabenazine has a major potential interaction with Arrhythmia.

Tetrabenazine can cause an increase in the corrected QT interval. QT prolongation can lead to the development of ventricular arrhythmias. The use of tetrabenazine should be avoided in patients with congenital long QT syndrome and in patients with a history of arrhythmias.

Tetrabenazine has a moderate potential interaction with Breast Cancer.

Tetrabenazine can elevate serum prolactin concentrations. This should be considered when therapy will be prescribed in patients with previously detected breast cancer. Additionally, chronic increase in serum prolactin has been associated with low levels of estrogen and increase risk of osteoporosis. If there is suspicion of hyperprolactinemia, appropriate laboratory testing is advised and treatment discontinuation should be considered.

The polyethylene glycol 3350 with electrolytes in Plenvu has a moderate potential interaction with Dehydration.

Use caution when prescribing PEG electrolyte solutions to patients with impaired renal function or patients taking concomitant medications that may affect renal function. Ensure adequate hydration and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients.

Tetrabenazine has a major potential interaction with Depression.

The use of tetrabenazine is contraindicated in patients with untreated or uncontrolled depression. Tetrabenazine can increase the risk of depression and suicidal thoughts and behavior.

Tetrabenazine has a moderate potential interaction with Dysphagia.

Tetrabenazine reduces dopaminergic transmission and can be associated with esophageal dysmotility and dysphagia. Caution should be exercised when used in patients with conditions that predispose to dysphagia. Special caution is advised in patients with Huntington's disease as dysphagia is a common symptom and it could lead to aspiration pneumonia.

The polyethylene glycol 3350 with electrolytes in Plenvu has a moderate potential interaction with Esophageal Obstruction.

Patients with impaired gag reflex, unconscious or semi-conscious patients, and patients prone to regurgitation or aspiration should be administered polyethylene glycol (PEG) electrolyte solutions cautiously. Patients experiencing severe bloating, distention or abdominal pain may need to receive PEG electrolyte solutions at a slower rate.

The polyethylene glycol 3350 with electrolytes in Plenvu has a major potential interaction with Gastrointestinal Obstruction.

The use of polyethylene glycol (PEG) solutions is contraindicated in patients with gastrointestinal obstruction, perforation, or toxic megacolon. If gastrointestinal obstruction or perforation is suspected, appropriate studies should be performed prior to administration of these agents. Use with caution in patients with severe active ulcerative colitis. Increased activity of the gut caused by these agents could worsen these conditions.

The polyethylene glycol 3350 with electrolytes in Plenvu has a major potential interaction with Gastrointestinal Obstruction.

The use of laxatives is contraindicated in patients with intestinal obstruction disorders. Patients with intestinal obstruction disorders may need their underlying condition treated to correct the constipation. Some laxatives require reduction in the colon to their active form to be effective which may be a problem in patients with intestinal obstruction.

The polyethylene glycol 3350 with electrolytes in Plenvu has a major potential interaction with Gastrointestinal Perforation.

The use of polyethylene glycol (PEG) solutions is contraindicated in patients with gastrointestinal obstruction, perforation, or toxic megacolon. If gastrointestinal obstruction or perforation is suspected, appropriate studies should be performed prior to administration of these agents. Use with caution in patients with severe active ulcerative colitis. Increased activity of the gut caused by these agents could worsen these conditions.

The polyethylene glycol 3350 with electrolytes in Plenvu has a moderate potential interaction with Heart Disease.

The use of ionic osmotic laxative products for bowel preparation has been associated with rare reports of serious arrhythmias. Use caution when prescribing PEG electrolyte solutions in patients at increased risk of arrhythmias (e.g., patients with a history of prolonged QT, uncontrolled arrhythmias, recent myocardial infarction, unstable angina, congestive heart failure, or cardiomyopathy). Clinical monitoring of cardiovascular status is recommended prior to, during, and after therapy.

Tetrabenazine has a major potential interaction with Huntington's Disease.

Patients with Huntington disease are prone to depression. Tetrabenazine can increase the risk of depression and suicidal thoughts and should be used with caution in patients with Huntington's disease. The benefits and risks of treatment should be considered before starting therapy, and patients should be under close observation for emergence or worsening of depression symptoms. The family and caregivers should also be informed of this risk and should be instructed to report any changes in behavior or any concerns to the treating physician.

Tetrabenazine has a moderate potential interaction with Huntington's Disease.

Tetrabenazine reduces dopaminergic transmission and can be associated with esophageal dysmotility and dysphagia. Caution should be exercised when used in patients with conditions that predispose to dysphagia. Special caution is advised in patients with Huntington's disease as dysphagia is a common symptom and it could lead to aspiration pneumonia.

Tetrabenazine has a moderate potential interaction with Hyperprolactinemia.

Tetrabenazine can elevate serum prolactin concentrations. This should be considered when therapy will be prescribed in patients with previously detected breast cancer. Additionally, chronic increase in serum prolactin has been associated with low levels of estrogen and increase risk of osteoporosis. If there is suspicion of hyperprolactinemia, appropriate laboratory testing is advised and treatment discontinuation should be considered.

The polyethylene glycol 3350 with electrolytes in Plenvu has a moderate potential interaction with Hyponatremia.

PEG electrolyte solutions have been associated with seizure activity, and/or loss of consciousness. The seizure cases were associated with electrolyte abnormalities and low serum osmolality. Therapy with these agents should be administered cautiously in patients with a history of or predisposition to seizures or in patients with known or suspected hyponatremia.

Tetrabenazine has a moderate potential interaction with Hypotension.

Tetrabenazine can induce postural dizziness and syncope and should be used with caution in patients who are vulnerable to hypotension.

The polyethylene glycol 3350 with electrolytes in Plenvu has a major potential interaction with Inflammatory Bowel Disease.

The use of laxatives is contraindicated in patients with inflammatory bowel disease. Patients with inflammatory bowel disease may experience colonic perforation with use of stimulant laxatives.

Tetrabenazine has a major potential interaction with Liver Disease.

The use of tetrabenazine is contraindicated in patients with hepatic impairment. The safety and efficacy of exposure to the drug and other metabolites are unknown and it is not possible to adjust the dosage in hepatic impairment to ensure safe use.

Tetrabenazine has a moderate potential interaction with Osteoporosis.

Tetrabenazine can elevate serum prolactin concentrations. This should be considered when therapy will be prescribed in patients with previously detected breast cancer. Additionally, chronic increase in serum prolactin has been associated with low levels of estrogen and increase risk of osteoporosis. If there is suspicion of hyperprolactinemia, appropriate laboratory testing is advised and treatment discontinuation should be considered.

The polyethylene glycol 3350 with electrolytes in Plenvu has a moderate potential interaction with Renal Dysfunction.

Use caution when prescribing PEG electrolyte solutions to patients with impaired renal function or patients taking concomitant medications that may affect renal function. Ensure adequate hydration and consider performing baseline and post-colonoscopy laboratory tests (electrolytes, creatinine, and BUN) in these patients.

The polyethylene glycol 3350 with electrolytes in Plenvu has a moderate potential interaction with Seizures.
