Moderate:
melatonin Food/Lifestyle
Applies to: melatonin
Both smoking and excessive caffeine consumption can alter the blood levels of melatonin, which may affect the dosing. Tobacco smoking reduces, while caffeine increases melatonin blood levels. If you start smoking or undergo smoking cessation, your doctor may need to adjust the dose of melatonin. In addition, alcohol may reduce the effect of melatonin on sleep. It is best to avoid alcohol consumption during melatonin therapy. Talk to a healthcare professional if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Disease interactions
18 potential interactions Applies to: 17 conditions, including High Blood Pressure, Depression, Heart Failure, Seizures, and Tardive Dyskinesia.
Cirrhosis
Moderate:
metoclopramide
Metoclopramide has a moderate potential interaction with Cirrhosis.
Metoclopramide produces a transient increase in plasma aldosterone and may cause fluid retention and volume overload in susceptible patients. Therapy with metoclopramide should be administered cautiously in patients with or at risk for fluid overload (e.g., cirrhosis, congestive heart failure). If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued.
Depression
Major:
melatonin
Melatonin has a major potential interaction with Depression.
A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of most anxiolytics, sedatives and hypnotics. Some of these changes include decreased inhibition, aggressiveness, agitation, and hallucinations. These drugs can cause or exacerbate mental depression and cause suicidal behavior and ideation. Therapy with these drugs should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Major:
metoclopramide
Metoclopramide has a major potential interaction with Depression.
Metoclopramide has been reported to cause mental depression in patients with and without a prior history of depression. Symptoms have ranged from mild to severe and have included suicidal ideation and suicide. Therapy with metoclopramide in patients with a history of mental depression, especially suicidal tendencies, should be administered cautiously, and only if benefits are anticipated to outweigh the potential risks. Some patients who experience depression with metoclopramide have improved following temporary discontinuation of the drug and reinstitution at a lower dosage with gradual titration.
Fluid Retention
Moderate:
metoclopramide
Metoclopramide has a moderate potential interaction with Fluid Retention.
Metoclopramide produces a transient increase in plasma aldosterone and may cause fluid retention and volume overload in susceptible patients. Therapy with metoclopramide should be administered cautiously in patients with or at risk for fluid overload (e.g., cirrhosis, congestive heart failure). If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued.
Gastrointestinal Hemorrhage
Major:
metoclopramide
Metoclopramide has a major potential interaction with Gastrointestinal Hemorrhage.
The use of metoclopramide is contraindicated in patients with conditions where stimulation of gastrointestinal motility might be harmful, such as mechanical bowel obstruction, bowel perforation, or gastrointestinal hemorrhage.
Gastrointestinal Perforation
Major:
metoclopramide
Metoclopramide has a major potential interaction with Gastrointestinal Perforation.
The use of metoclopramide is contraindicated in patients with conditions where stimulation of gastrointestinal motility might be harmful, such as mechanical bowel obstruction, bowel perforation, or gastrointestinal hemorrhage.
Glaucoma/Intraocular Hypertension
Moderate:
melatonin
Melatonin has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.
Heart Failure
Moderate:
metoclopramide
Metoclopramide has a moderate potential interaction with Heart Failure.
Metoclopramide produces a transient increase in plasma aldosterone and may cause fluid retention and volume overload in susceptible patients. Therapy with metoclopramide should be administered cautiously in patients with or at risk for fluid overload (e.g., cirrhosis, congestive heart failure). If these side effects occur at any time during metoclopramide therapy, the drug should be discontinued.
High Blood Pressure
Moderate:
metoclopramide
Metoclopramide has a moderate potential interaction with High Blood Pressure.
In a study involving patients with essential hypertension, intravenously administered metoclopramide was shown to induce the release of catecholamines. Therapy with metoclopramide should be administered cautiously in patients with hypertension because of potential increases in blood pressure.
Intestinal Obstruction
Major:
metoclopramide
Metoclopramide has a major potential interaction with Intestinal Obstruction.
The use of metoclopramide is contraindicated in patients with conditions where stimulation of gastrointestinal motility might be harmful, such as mechanical bowel obstruction, bowel perforation, or gastrointestinal hemorrhage.
Liver Disease
Moderate:
melatonin
Melatonin has a moderate potential interaction with Liver Disease.
In general, anxiolytics, sedatives and hypnotics are extensively metabolized by the liver. Their plasma clearance may be decreased and their half-life prolonged in patients with impaired hepatic function. Therapy with these drugs should be administered cautiously in patients with liver disease (some are not recommended in severe liver impairment), and the dosage should be adjusted accordingly. Laboratory testing is recommended prior and during treatment.
Neuroleptic Malignant Syndrome
Major:
metoclopramide
Metoclopramide has a major potential interaction with Neuroleptic Malignant Syndrome.
Although not a neuroleptic agent, metoclopramide has antidopaminergic effects and may rarely precipitate or aggravate a potentially fatal symptom complex known as Neuroleptic Malignant Syndrome (NMS). Clinical manifestations of NMS include hyperpyrexia, muscle rigidity, involuntary movements, altered mental status and autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis and cardiac arrhythmias). Metoclopramide therapy should not be initiated in patients with active NMS and should be immediately discontinued if currently being administered in such patients. In patients with a history of NMS, introduction or reintroduction of metoclopramide or other antidopaminergic therapy should be carefully considered, since NMS may recur.
Parkinsonism
Moderate:
metoclopramide
Metoclopramide has a moderate potential interaction with Parkinsonism.
Metoclopramide has antidopaminergic effects and may cause parkinsonian-like symptoms such as akinesia, bradykinesia, tremors, pill-rolling motion, cogwheel rigidity, and postural abnormalities including stooped posture and shuffling gait. The onset is usually within the first six months following initiation of therapy but occasionally after longer periods. Symptoms generally subside within 2 to 3 months after drug discontinuation. Therapy with metoclopramide should be administered cautiously, if at all, in patients with Parkinson's disease or parkinsonian symptoms.
Pheochromocytoma
Major:
metoclopramide
Metoclopramide has a major potential interaction with Pheochromocytoma.
The use of metoclopramide is contraindicated in patients with pheochromocytoma. In a study involving patients with essential hypertension, intravenously administered metoclopramide was shown to induce the release of catecholamines. Hypertensive crises may occur in patients with pheochromocytoma due to induction of catecholamine release from the tumor.
Renal Dysfunction
Moderate:
metoclopramide
Metoclopramide has a moderate potential interaction with Renal Dysfunction.
Renal function affects the clearance of metoclopramide. In patients with varying degrees of renal impairment, a reduction in creatinine clearance was correlated with a reduction in plasma clearance, renal clearance, and non-renal clearance, and increase in elimination half-life of metoclopramide. Therapy with metoclopramide should be administered cautiously in patients with impaired renal function. A dosage reduction may be appropriate to avoid drug accumulation.
Seizures
Major:
metoclopramide
Metoclopramide has a major potential interaction with Seizures.
The use of metoclopramide is contraindicated in patients with seizure disorders. Metoclopramide may increase the frequency and severity of seizures.
Tardive Dyskinesia
Major:
metoclopramide
Metoclopramide has a major potential interaction with Tardive Dyskinesia.
Metoclopramide may precipitate symptoms of tardive dyskinesia (TD) following chronic administration. Elderly patients, particularly women, are most susceptible. Both the risk of developing TD and the likelihood that it will become irreversible increase with the duration and total cumulative dose of metoclopramide or other antidopaminergic therapy administered. Metoclopramide therapy should be discontinued in patients who develop signs or symptoms of tardive dyskinesia. There is no known treatment for tardive dyskinesia. In some patients, symptoms may lessen or resolve after metoclopramide treatment is stopped. Treatment with metoclopramide for longer than 12 weeks should be avoided in all but rare cases where therapeutic benefit is thought to outweigh the risk of developing tardive dyskinesia. In patients with preexisting drug-induced TD, initiating or increasing the dosage of metoclopramide therapy may temporarily mask the symptoms of TD but may eventually worsen the condition.
Urinary Retention
Moderate:
melatonin
Melatonin has a moderate potential interaction with Urinary Retention.
Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.
