Interactions between your drugs
hydrOXYzine ivabradine
Applies to: hydroxyzine and ivabradine
GENERALLY AVOID: Due to its bradycardic effects, the risk of QT prolongation and torsade de pointes arrhythmia may be increased when ivabradine is used with drugs that prolong the QT interval. In clinical studies in adult patients, the rate of bradycardia was 6.0% versus 1.3% per patient-year for ivabradine compared to placebo. Asymptomatic and symptomatic bradycardia were observed in 6.8% and 4.1% of the pediatric patients treated with ivabradine compared to 2.4% and 0% in the placebo treatment group, respectively. At recommended dosages of ivabradine, heart rate reduction is approximately 10 beats per minute at rest and during exercise. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease, and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia). In addition, the extent of drug-induced QT prolongation is dependent on the particular drug(s) involved and dosage(s) of the drug(s).
MANAGEMENT: Coadministration of ivabradine with drugs that can prolong the QT interval should generally be avoided. Caution and cardiac monitoring are recommended if concomitant use is required. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.

Drug and food interactions
ivabradine food
Applies to: ivabradine
GENERALLY AVOID: Grapefruit juice may significantly increase the plasma concentrations of ivabradine. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. According to the product labeling, administration with grapefruit juice (quantity unknown) resulted in an approximately twofold increase in ivabradine systemic exposure (AUC). Elevated plasma levels of ivabradine may increase the risk of excessive bradycardia and conduction disturbances.
ADJUST DOSING INTERVAL: Food delays the absorption of ivabradine by approximately 1 hour and increases plasma exposure by 20% to 40% compared to fasting conditions.
MANAGEMENT: Patients treated with ivabradine should avoid or limit consumption of grapefruit or grapefruit juice. The manufacturer recommends taking ivabradine with meals to reduce variability in exposure.

hydrOXYzine food
Applies to: hydroxyzine
GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.
