What to use for viral infection and sore throat?

If it is a viral infection, then the antibiotic will not be effective. Perhaps you use the above-mentioned painkillers in too small doses, so the effect is insufficient. You can, for example, take oral painkillers, e.g. with ibuprofen every 6-8 hours, and use a borax-based disinfectant to gargle. Because rinses and analgesic sprays can dry out the mucosa, you should also take care of its proper hydration by using moisturizing pastilles, e.g. with Icelandic lichen. Here you can compare the prices of sample products and order them with home delivery or collection at the pharmacy: oral analgesics, e.g. https://www.gdziepolek.pl/produkty/89706/ibum-express-kapsulki/apteki https://www.gdziepolek.pl/produkty/100915/ibuprex-max-tabletki-powlekane/apteki disinfectants with borax, e.g. https://www.gdziepolek.pl/produkty/31944/gargarin-proszek-do-wytworzenia-plynu/apteki https://www.gdziepolek.pl/produkty/31944/gargarin-proszek-do-wytworzenia-plynu/apteki moisturizing pills, e.g. https://www.gdziepolek.pl/produkty/29892/fiorda-o-smaku-czarnej-porzeczki-pastylki-lamelki-zelki/apteki https://www.gdziepolek.pl/produkty/38370/isla-cassis-pastylki-lamelki-zelki/apteki If, despite the use of the above-mentioned drugs, the symptoms do not disappear within 2-3 days, you should consult your doctor again.
