Yes, you can use all medicines at the same time. Between Tetralysal and Atarax I would recommend keeping a time interval of at least 2-3 hours. Epiduo Forte, on the other hand, is a topical preparation whose active ingredients are absorbed into the bloodstream to a small extent. Therefore, there is no risk of harmful interactions of the preparations. Please observe the recommended dosage for all preparations.

The availability of Atarax, Epiduo Forte and Tetralysal in pharmacies in Polish can be found here:
