Which drugs or supplements interact with hydrocodone homatropine?

Combining alcohol and other sedatives with hydrocodone can lead to increased sedation and even cause confusion. Hydrocodone should not be taken with any of the monoamine oxidase inhibitor (MAOI) class of antidepressants, for example, isocarboxazid (Marplan), phenelzine (Nardil), tranylcypromine (Parnate), selegiline (Eldepryl), and procarbazine (Matulane) or other drugs that inhibit monoamine oxidase, for example, linezolid (Zyvox). Such combinations may lead to confusion, high blood pressure, tremor, hyperactivity, coma, and death.

Hydrocodone should not be administered within 14 days of stopping an MAOI.

How does hydrocodone homatropine work?
  • Hydrocodone, like other opioids, stimulates receptors on nerves in the brain to increase the threshold to pain (the amount of stimulation it takes to feel pain) and reduce the perception of pain (the perceived importance of the pain).
  • It also works directly on the cough center in the brain to reduce cough.
  • Homatropine blocks the action of acetylcholine, a chemical (neurotransmitter) that nerves use to communicate. It is added in low doses to discourage deliberate overdoses of hydrocodone.
When was hydrocodone homatropine approved by the FDA?

The FDA approved hydrocodone homatropine in July 1985.
