Do you need a prescription to buy potassium soap in a pharmacy and what is its composition?

Potassium soap is a pharmaceutical raw material - it can be a component of drugs made in a pharmacy, made on the basis of a doctor's prescription. The price of 1 gram of potassium soap is from PLN 0.15 to PLN 1.01, but the patient's payment for the prescription drug depends on the composition and the related valuation. From January 2022, the amount of the lump sum (fixed fee) for the prescription drug is PLN 15.10. However, if the prescription is not discounted, the patient must pay the full value of the raw materials used and the work of the pharmacist: https://www.gdziepolek.pl/artykuly/leki-recepturowe-robione-w-aptece https://www.gdziepolek.pl/produkty/50999/mydlo-potasowe-plyn/apteki/w-polsce Potassium soap is made using linseed oil, potassium hydroxide, ethanol and water.
