Drug interactions
Moderate drug interactions
Moderate:
methdilazine carisoprodol
Applies to: methdilazine and Soma (carisoprodol)
Using methdilazine together with carisoprodol may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you. Talk to your doctor 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.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
carisoprodol Food/Lifestyle
Applies to: Soma (carisoprodol)
Alcohol can increase the nervous system side effects of carisoprodol such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with carisoprodol. Do not use more than the recommended dose of carisoprodol, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
Moderate:
methdilazine Alcohol (Ethanol)
Applies to: methdilazine
Ask your doctor before using methdilazine together with ethanol (alcohol). This can cause uncontrollable movements, agitation, seizures, severe dizziness or fainting, coma, very deep sleep, irregular heartbeats, and high or low body temperature. Use caution when driving, operating machinery, or performing other hazardous activities, these medicaions may cause dizziness or drowsiness. If you experience dizziness or drowsiness, avoid these activities. 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
10 potential interactions Applies to: 10 conditions, including Asthma, COPD, Urinary Retention, Liver Disease, and Drug Dependence.
Alcoholism
Moderate:
Soma
The carisoprodol in Soma has a moderate potential interaction with Alcoholism.
Carisoprodol is partially metabolized to meprobamate, a pharmacologically active agent with known addictive potential. According to the manufacturer, abrupt cessation of carisoprodol 100 mg/kg/day (approximately 5 times the recommended daily adult dosage) was associated with mild withdrawal symptoms such as abdominal cramps, insomnia, headache, nausea and chills in some study subjects. In clinical use, psychological dependence and abuse have been rare. Nevertheless, therapy with carisoprodol should be administered cautiously in addiction-prone individuals, such as those with a history of alcohol or substance abuse. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Asthma
Moderate:
methdilazine
Methdilazine has a moderate potential interaction with Asthma.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
COPD
Moderate:
methdilazine
Methdilazine has a moderate potential interaction with COPD.
It has been suggested that the anticholinergic effect of antihistamines may reduce the volume and cause thickening of bronchial secretions, resulting in obstruction of respiratory tract. Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Drug Dependence
Moderate:
Soma
The carisoprodol in Soma has a moderate potential interaction with Drug Dependence.
Carisoprodol is partially metabolized to meprobamate, a pharmacologically active agent with known addictive potential. According to the manufacturer, abrupt cessation of carisoprodol 100 mg/kg/day (approximately 5 times the recommended daily adult dosage) was associated with mild withdrawal symptoms such as abdominal cramps, insomnia, headache, nausea and chills in some study subjects. In clinical use, psychological dependence and abuse have been rare. Nevertheless, therapy with carisoprodol should be administered cautiously in addiction-prone individuals, such as those with a history of alcohol or substance abuse. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Gastrointestinal Obstruction
Moderate:
methdilazine
Methdilazine has a moderate potential interaction with Gastrointestinal Obstruction.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Glaucoma/Intraocular Hypertension
Moderate:
methdilazine
Methdilazine has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Liver Disease
Moderate:
Soma
The carisoprodol in Soma has a moderate potential interaction with Liver Disease.
Carisoprodol is primarily converted in the liver to several metabolites, one of which (meprobamate) is pharmacologically active. The metabolites and a small amount of the parent drug are excreted in the urine. Patients with impaired renal and/or hepatic function may be at greater risk for adverse effects due to drug and metabolite accumulation. Therapy with carisoprodol should be administered cautiously in such patients.
Porphyria
Major:
Soma
The carisoprodol in Soma has a major potential interaction with Porphyria.
The use of carisoprodol is contraindicated in patients with acute intermittent porphyria. Carisoprodol is partially metabolized to the pharmacologically active meprobamate, which has been reported to precipitate acute attacks of porphyria in susceptible patients.
Renal Dysfunction
Moderate:
Soma
The carisoprodol in Soma has a moderate potential interaction with Renal Dysfunction.
Carisoprodol is primarily converted in the liver to several metabolites, one of which (meprobamate) is pharmacologically active. The metabolites and a small amount of the parent drug are excreted in the urine. Patients with impaired renal and/or hepatic function may be at greater risk for adverse effects due to drug and metabolite accumulation. Therapy with carisoprodol should be administered cautiously in such patients.
Urinary Retention
Moderate:
methdilazine
Methdilazine has a moderate potential interaction with Urinary Retention.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects.
