Which of the following is NOT a common form of medication?

When considering the various forms of medication, typical categories include liquids, semi-solids, and solids. Liquids encompass syrups, solutions, and suspensions, designed for easy ingestion or application. Semi-solids refer to formulations such as creams, gels, and ointments, which are commonly used for topical application. Solids typically consist of tablets, capsules, and powders, commonly prescribed for systemic effects.

Compresses, although used in therapeutic contexts such as applying heat or cold to a specific area, do not classify as a primary form of medication. They utilize a cloth soaked in a medicinal solution, but they are not a stand-alone medication form comparable to the others listed. Therefore, identifying compresses as not being a common form of medication is accurate in the context of traditional medication classifications.
