Can an 8-year-old use Oftahist drops prescribed by an ophthalmologist?

Yes, it can, especially if the medicine is used as directed by your doctor. In some cases, the doctor may also order the preparation outside the manufacturer's indications, if he knows that such a procedure may bring health benefits to the patient. It then uses "off-label" drugs, i.e. outside the manufacturer's indications. We wrote more about it here: https://www.gdziepolek.pl/artykuly/leczenie-off-label-poza-wskazaniami In general, olopatadine (the active substance in Oftahsit) is registered for use in children over 3 years of age. The usual doses are one drop to twice a day (in each eye). In case of doubt, I encourage you to consult your doctor again. It is the doctor who decides whether to treat the patient m.in based on the history of the disease and the previous response to treatment. Only a doctor can decide on a possible change in pharmacotherapy. If you are unable to get to your doctor, the GdziePoLek.pl service also allows you to obtain a teleconsultation with a doctor: https://www.gdziepolek.pl/telekonsultacja I enclose a link to a page where you can compare the prices of Oftahsit in online pharmacies and place an order with home delivery or collection at the nearest stationary pharmacy: https://www.gdziepolek.pl/produkty/55904/oftahist-krople-do-oczu/apteki
