Can I use this ointment together with other creams, antiseptics, or prescription topicals? — ICHTYOOL SALV 25G (Тверская ф.ф., Россия)

Because the vaseline base creates an occlusive barrier, layering another cream or gel on top will prevent the second product from penetrating properly. If you need to combine treatments, use them at different times of day — for example, a prescribed morning topical and ichthyol ointment in the evening — and cleanse the area between applications. Avoid simultaneous use with strong antiseptics (such as iodine or chlorhexidine solutions) or drying agents (alcohol-based toners, benzoyl peroxide) on the same spot, as the combination can increase irritation. If you are using any prescription topical medication — corticosteroids, retinoids, calcineurin inhibitors — ask your prescribing clinician or a pharmacist before adding ichthyol ointment to the routine. They can advise on safe sequencing and whether the occlusive effect might alter the drug's absorption. For general cosmetic moisturisers, apply them to surrounding unaffected skin only, not over the ointment.
