Interactions between your drugs

Moderate

isoniazid mephobarbital

Applies to: isoniazid and Mebaral (mephobarbital)

Consumer information for this interaction is not currently available.

MONITOR: Limited clinical data suggest that nonselective monoamine oxidase inhibitors (MAOIs) may enhance or prolong the central nervous system effects of barbiturates. The mechanism of interaction is unknown, but may involve inhibition of barbiturate metabolism by MAOIs. Somnolence, dizziness, ataxia, and semi-consciousness have been reported.

MANAGEMENT: Until more information is available, patients should be monitored for increased barbiturate effects during coadministration with an MAOI or other agents that possess MAOI activity such as furazolidone, linezolid, methylene blue, and procarbazine.

Moderate

isoniazid food

Applies to: isoniazid

Food decreases the levels of isoniazid in your body. Take isoniazid on an empty stomach at least 1 hour before or 2 hours after a meal. This will make it easier for your body to absorb the medication. If nausea occurs, ask your doctor if you can take isoniazid with food. Avoid alcohol while taking isoniazid. Alcohol may increase the risk of damage to the liver during isoniazid treatment. Alcohol can also cause isoniazid side effects to get worse. Contact your doctor if you experience flushing, chills, headache, nausea, vomiting, and diarrhea.
