Interactions between your drugs

Major

iohexol DULoxetine

Applies to: Omnipaque 180 (iohexol) and duloxetine

GENERALLY AVOID: Intrathecal administration of iodinated contrast media may induce seizures. Although clinical data are generally lacking, there may be a theoretical risk of increased seizure potential when used with selective serotonin reuptake inhibitors (SSRI antidepressants or anorectics), monoamine oxidase inhibitors, neuroleptic agents, central nervous system stimulants, opioids, tricyclic antidepressants, other tricyclic compounds (e.g., cyclobenzaprine, phenothiazines), and/or any substance that can reduce the seizure threshold (e.g., carbapenems, cholinergic agents, fluoroquinolones, interferons, chloroquine, mefloquine, lindane, theophylline). These agents are often individually epileptogenic and may have additive effects when combined.

MANAGEMENT: Drugs that can lower the seizure threshold should preferably be withheld for at least 48 hours prior to and 24 hours following intrathecal administration of iodinated contrast media, provided that temporary interruption of therapy does not pose an undue risk to the patient. Otherwise, close monitoring is advised during and after contrast administration. The manufacturers typically recommend avoiding concomitant administration of phenothiazines (including those used for their antihistamine properties), monoamine oxidase inhibitors, tricyclic antidepressants, central nervous system stimulants, and psychoactive drugs.

Drug and food interactions

Moderate

DULoxetine food

Applies to: duloxetine

GENERALLY AVOID: Use of duloxetine in conjunction with chronic alcohol consumption may potentiate the risk of liver injury. Duloxetine alone can increase serum transaminase levels. In clinical trials, 0.3% of patients discontinued duloxetine due to liver transaminase elevations. The median time to detection was about two months. Three duloxetine-treated patients had liver injury as manifested by transaminase and bilirubin elevations, with evidence of obstruction. Substantial intercurrent ethanol use was present in each of these cases, which may have contributed to the abnormalities observed. Duloxetine does not appear to enhance the central nervous system effects of alcohol. When duloxetine and ethanol were administered several hours apart so that peak concentrations of each would coincide, duloxetine did not increase the impairment of mental and motor skills caused by alcohol.

MANAGEMENT: Due to the risk of liver injury, patients prescribed duloxetine should be counseled to avoid excessive use of alcohol. Duloxetine should generally not be prescribed to patients with substantial alcohol use.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
