Which is safer - Zomiren SR or Hydroxyzina?

It depends on what you mean by "safer" and for whom. Each drug has its own profile of action, indications, contraindications and side effects. In the case of Zomiren SR, it should be noted first of all that it is indicated only for severe symptoms, when the patient is unable to function normally. At the same time, the total duration of treatment should not exceed 8-12 weeks, including the dose reduction period. It is therefore a drug that should be used relatively briefly due to the risk of developing addiction. Hydroxysin, on the other hand, gives a high risk of drowsiness (sometimes it is used in therapy, but the "residual effect" may persist even when the patient no longer wants to sleep), it is not recommended in the elderly, it can negatively affect heart problems. Both drugs are prescription - the choice of product for a particular patient should be made by a doctor.
