• Drug toleranceRelated: Interactions can alter exposure or effects, complicating dose decisions in tolerant patients.

• AzithromycinRelated: Azithromycin can interact with other drugs, including through effects on cardiac rhythm risk.

• Complementary and alternative medicineRelated: Herbs and supplements may alter prescription-drug effects when used alongside conventional care.

• TurmericRelated: Concentrated turmeric products may affect medicines or increase risks such as bleeding.

• LamotrigineRelated: Valproate raises lamotrigine levels, while enzyme-inducing antiseizure drugs can lower them.

• PropranololRelated: Other medicines can alter propranolol levels or intensify its effects on heart rate and blood pressure.

• Over-the-counter drugRelated: OTC products can interact with prescriptions and supplements, often without obvious warning signs.

• BuspironeRelated: Strong CYP3A4 inhibitors can raise buspirone exposure, and grapefruit may also affect levels.

• ContraindicationRelated: An interaction can create a treatment hazard that functions as a contraindication.

• Hormonal contraceptionRelated: Certain medicines can reduce the effectiveness of some hormonal methods.

• Psychiatric medicationRelated: Interactions can alter psychiatric medication levels or increase risks such as sedation and toxicity.

• PsychopharmacologyRelated: Interactions can alter psychiatric drug levels or intensify sedation and other harms.

• Drug overdoseRelated: Combining depressants can intensify impairment and breathing suppression beyond either substance alone.

• PiperineRelated: Piperine’s effects on drug-metabolizing enzymes and transporters can alter medication exposure.

• Active metaboliteRelated: Interactions can alter the enzymes that form or clear active metabolites.

• Azole antifungalRelated: Many azoles inhibit human drug-metabolizing enzymes and raise concentrations of coadministered medicines.

• CetirizineRelated: Alcohol and other sedating substances can increase impairment when combined with cetirizine.

• PharmacotherapyRelated: Interactions can alter treatment effectiveness or create unexpected harm.

• Prescription drugRelated: Prescribers and pharmacists assess interactions before treatment and dispensing.

• CannabidiolRelated: CBD can alter the metabolism of some medicines, including drugs used to treat epilepsy.

• TacrolimusRelated: Enzyme inhibitors and inducers can sharply alter tacrolimus exposure and toxicity risk.

• OmeprazoleRelated: Omeprazole’s enzyme inhibition can alter the handling of particular co-administered medicines.

• Clinical pharmacologyRelated: Interactions can change exposure or response and make a previously suitable regimen unsafe.

• Contraceptive implantRelated: Some enzyme-inducing medicines can lower etonogestrel levels and reduce contraceptive effectiveness.

• PromethazineRelated: Alcohol and other sedatives can amplify promethazine's effects on alertness and breathing.

• SirolimusRelated: CYP3A4 and P-glycoprotein interactions can sharply alter sirolimus exposure.

• TheophyllineRelated: Smoking and medicines such as ciprofloxacin can substantially alter theophylline concentrations.
