Is the combination of Estazolam and Hydroxyzine dangerous?

Both Estazolam and Hydroxyzine are sedatives, anxiolytics. Using them in the way you described can cause excessive drowsiness. However, there should be no interaction that threatens health. Both Estazolam and Hydroxyzine should be used strictly according to medical recommendations. The maximum effect of Estazolam after taking the tablet is within 2 hours. This is not a drug intended for long-term use. Hydroxyzine, in turn, acts an hour after taking. We dose individually depending on the patient's condition (the smallest effective dose should be used).
