Is the expression “strong medicine” idiomatic?
I am referring to drugs that contain a high concentration of chemicals and are used for soothing severe pains or treating severe diseases. A drug whose dosage of chemicals is higher compared to your average over-the-counter drugs.
Can I say the following:
You need some strong medicine to take away the pain
I want to ask my doctor for some strong medicine
Is there perhaps a more idiomatic expression used in the US or in the UK?
