Hydrocodone, also known as dihydrocodeinone, is a semi-synthetic opioid used to treat pain and as a cough suppressant.[10] It is taken by mouth.[10] Typically, it is dispensed as the combination acetaminophen/hydrocodone or ibuprofen/hydrocodone for pain severe enough to require an opioid[11][12][13] and in combination with homatropine methylbromide to relieve cough.[10] It is also available by itself in a long-acting form sold under the brand name Zohydro ER, among others, to treat severe pain of a prolonged duration.[10][14] Hydrocodone is a controlled drug: in the United States, it is classified as a Schedule II Controlled Substance.

Common side effects include dizziness, sleepiness, nausea, and constipation.[10] Serious side effects may include low blood pressure, seizures, QT prolongation, respiratory depression, and serotonin syndrome.[10] Rapidly decreasing the dose may result in opioid withdrawal.[10] Use during pregnancy or breastfeeding is generally not recommended.[15] Hydrocodone is believed to work by activating opioid receptors, mainly in the brain and spinal cord.[10] Hydrocodone 10 mg is equivalent to about 10 mg of morphine by mouth.[16]
