Steer clear of or Use Alternate Drug. Restrict use to patients for whom alternative treatment choices are insufficient
If inducer is discontinued, consider oliceridine dosage reduction and monitor for signs of respiratory depression.Critical - Use Alternative (one)oliceridine and phenobarbital both equally increase sedation.

When epilepsy drugs such as phenobarbital are abused, it may possibly amplify the effects of other substances or prescription drugs and result in a fatal overdose.

Monitor Intently (one)phenobarbital will lower the level or effect of oliceridine by impacting hepatic/intestinal enzyme CYP3A4 metabolism. Use Caution/Monitor. If coadministration with a CYP3A4 inducer is necessary, consider raising oliceridine dose till secure drug effects are attained; monitor for signs of opioid withdrawal.
Contraindicated. Contraindicated. Rilpivirine really should not be co-administered with strong CYP 3A4 inducers. Potential for loss of virologic reaction and attainable resistance to rilpivirine or for the NNRTI class.
Comment: Barbiturates could increase adverse effects, like respiratory depression, made by harmful doses of TCAs. With therapeutic doses of TCAs, barbiturates increase metabolism and decrease blood concentrations of TCAs.
1. Habit forming: Phenobarbital can be practice forming. Tolerance, psychological and Bodily dependence may possibly happen with continued use. (See ADVERSE REACTIONS: Drug Abuse and Dependence). To reduce the potential of overdosage or the development of dependence, the prescribing and dispensing of sedative-hypnotic barbiturates really should be limited to the amount required for the interval right until the next appointment.

The transfer to benzodiazepines within the 60s as typical sedative observed a significant mortality reduction in inadvertent or intentional overdoses. Many withdrawals are managed in low-resourced configurations and there is a valid problem of inappropriate dosing, insufficient monitoring, toxicity and adverse situations.

Drugs that have amount boundaries linked with Every prescription. This restriction ordinarily limits the quantity with the drug which will be covered.
Contraindicated. Coadministration of doravirine with a strong CYP3A inducer may possibly lessen doravirine plasma concentrations and/or effects. Potential for loss of virologic reaction and possible resistance to doravirine.
phenobarbital will lower the level or effect of paclitaxel protein certain by Other (see remark). Use Caution/Monitor. Paclitaxel levels/efficacy may minimize when coadministered with CYP2C8 inducers Slight (one)phenobarbital will lessen the level or effect of paclitaxel protein bound by affecting hepatic/intestinal enzyme CYP3A4 metabolism. Insignificant/Significance Unknown.
