Can I return to using Ducrossa if my symptoms return after a week?

Ducressa is a prescription medicine and should be used exactly as your doctor has told you. Usually, the total period of treatment with drops is 7 days. The leaflet does not describe the possibility of repeating the treatment, but the doctor may recommend a different procedure: https://www.gdziepolek.pl/produkty/107215/ducressa-krople-do-oczu/apteki If the symptoms return after a week, I encourage you to consult a doctor. It is also possible to use the teleadvice offered, m.in. by the Gdziepolek.pl portal: https://www.gdziepolek.pl/telekonsultacja I encourage you to read our study on how to use eye drops: https://www.gdziepolek.pl/artykuly/jak-stosowac-krople-do-oczu
