This report displays the potential drug interactions for the following 2 drugs:
- Co-Tussin (guaifenesin/hydrocodone)
- pegvisomant
Interactions between your drugs
HYDROcodone pegvisomant
Applies to: Co-Tussin (guaifenesin / hydrocodone) and pegvisomant
MONITOR: In clinical trials, patients on opioids often required higher serum pegvisomant concentrations to achieve appropriate IGF-I (insulin-like growth factor-I) suppression compared with patients not receiving opioids. The mechanism of interaction is unknown.
MANAGEMENT: Clinicians should be aware of this potential interaction and adjust the dosage of pegvisomant appropriately in patients treated with opioids.

Drug and food interactions
HYDROcodone food
Applies to: Co-Tussin (guaifenesin / hydrocodone)
GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including hydrocodone. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.
GENERALLY AVOID: Consumption of alcohol while taking some sustained-release formulations of hydrocodone may cause rapid release of the drug, resulting in high systemic levels of hydrocodone that may be potentially lethal. Alcohol apparently can disrupt the release mechanism of some sustained-release formulations. In study subjects, the rate of absorption of hydrocodone from an extended-release formulation was found to be affected by coadministration with 40% alcohol in the fasted state, as demonstrated by an average 2.4-fold (up to 3.9-fold in one subject) increase in hydrocodone peak plasma concentration and a decrease in the time to peak concentration. Alcohol also increased the extent of absorption by an average of 1.2-fold (up to 1.7-fold in one subject).
GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of hydrocodone. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism of hydrocodone by certain compounds present in grapefruit. Increased hydrocodone concentrations could conceivably increase or prolong adverse drug effects and may cause potentially fatal respiratory depression.
MANAGEMENT: Patients taking sustained-release formulations of hydrocodone should not consume alcohol or use medications that contain alcohol. In general, potent narcotics such as hydrocodone should not be combined with alcohol. Patients should also avoid consumption of grapefruit or grapefruit juice during treatment with hydrocodone.
