Avoid SYMFI with concurrent or recent use of a nephrotoxic agent (e.g., high-dose or multiple non-steroidal anti-inflammatory drugs [NSAIDs]) [see Drug Interactions (7.3) ] .

Cases of acute renal failure after initiation of high-dose or multiple NSAIDs have been reported in HIV-infected patients with risk factors for renal dysfunction who appeared stable on TDF.

Alternatives to NSAIDs should be considered, if needed, in patients at risk for renal dysfunction.

Some examples include, but are not limited to, acyclovir, cidofovir, ganciclovir, valacyclovir, valganciclovir, aminoglycosides (e.g., gentamicin), and high-dose or multiple NSAIDs [see Warnings and Precautions (5.4) ] .

Narcotic analgesic: Methadone ↓ methadone Monitor for signs of methadone withdrawal and increase methadone dose if required to alleviate withdrawal symptoms.

Cytochrome P450 3A4 Interaction The concomitant use of Hydrocodone Bitartrate and Ibuprofen Tablets with all cytochrome P450 3A4 inhibitors may result in an increase in hydrocodone plasma concentrations, which may cause potentially fatal respiratory depression.

In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in hydrocodone plasma concentration.

Monitor patients taking Hydrocodone Bitartrate and Ibuprofen Tablets and any CYP3A4 inhibitor or upon discontinuation of a CYP3A4 inducer for signs and symptoms of respiratory depression and sedation (see WARNINGS: Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers, PRECAUTIONS: Drug Interactions).

Risks of Concomitant Use or Discontinuation of Cytochrome P450 3A4 Inhibitors and Inducers Concomitant use of Hydrocodone Bitartrate and Ibuprofen Tablets with a CYP3A4 inhibitor, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), and protease inhibitors (e.g., ritonavir), may increase plasma concentrations of hydrocodone…

Similarly, discontinuation of a CYP3A4 inducer, such as rifampin, carbamazepine, and phenytoin, in Hydrocodone Bitartrate and Ibuprofen Tablets -treated patients may increase hydrocodone plasma concentrations and prolong opioid adverse reactions.
