Warnings and Precautions

Before starting Comfortin, discuss it with your doctor or pharmacist.
Taking Comfortin may be associated with an increased risk of heart rhythm disturbances, which can be life-threatening. Therefore, tell your doctor about any heart problems and about taking any other medicines, including those available without a prescription.
If you experience heart symptoms such as rapid heartbeat (palpitations), difficulty breathing, or loss of consciousness while taking Comfortin, seek medical attention immediately. You should stop taking hydroxyzine.
You should be particularly cautious when taking Comfortin:

myasthenia gravis(a disease characterized by muscle weakness and fatigue after repeated effort; initial symptoms include: drooping eyelids, double vision, nasal voice, difficulty chewing and swallowing, difficulty lifting arms and walking; rarely, respiratory muscle weakness occurs); or dementia (reduced mental performance);

Comfortin tablets should be discontinued at least 5 days before performing allergy tests or the so-called methacholine bronchial provocation test to avoid the influence of the medicine on the test results.
Use in women of childbearing age - see "Pregnancy, breastfeeding, and fertility".

Comfortin and Other Medicines

Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.
This includes medicines available without a prescription.
Comfortin may affect the action of other medicines. Other medicines may affect the action of Comfortin.
Taking hydroxyzine with medicines that depress the central nervous system or have anticholinergic effects may require the use of a lower dose, which should be adjusted individually according to the patient's response.
Hydroxyzine acts antagonistically to betahistine and cholinesterase inhibitors.
Avoid concurrent administration of hydroxyzine with monoamine oxidase inhibitors (MAOIs).
Hydroxyzine limits the increase in blood pressure caused by adrenaline and reduces the anticonvulsant effect of phenytoin.
Since hydroxyzine is metabolized by alcohol dehydrogenase and CYP3A4/5, concurrent use of medicines that inhibit the action of these enzymes may lead to increased hydroxyzine levels in the blood.
Concomitant administration of hydroxyzine and medicines that may cause heart rhythm disturbances may increase the risk of changes in the ECG recording - QT interval prolongation or heart rhythm disturbances of the torsade de pointestype.
Caution should be exercised when using Comfortin with medicines that cause bradycardia and hypokalemia.
Do not take Comfortin if you are taking medicines used to treat:

• bacterial infections (e.g., antibiotics such as erythromycin, moxifloxacin, levofloxacin);
• fungal infections (e.g., pentamidine);
• heart disease or high blood pressure (e.g., amiodarone, quinidine, disopyramide, sotalol);
• psychoses (e.g., haloperidol);
• depression (e.g., citalopram, escitalopram);
• gastrointestinal diseases (e.g., prucalopride);
• allergies;
• malaria (e.g., mefloquine, hydroxychloroquine);
• cancer (e.g., toremifene, vandetanib);
• drug addiction or severe pain (methadone).

Comfortin with Alcohol

Do not drink alcohol while taking Comfortin, as it enhances the effect of the medicine.

Women of childbearing age must use appropriate contraception to prevent pregnancy during hydroxyzine treatment.

In newborns whose mothers received hydroxyzine during late pregnancy and/or during delivery, the following symptoms have been observed directly or a few hours after birth: tremors, stiffness, and/or muscle weakness, breathing problems, and urinary retention.
