What is the Difference between strength and dosage of a medication?

The strength of a medication refers to the concentration of the active ingredient in a specific volume or weight of the product, often expressed in units like milligrams (mg) or micrograms (mcg). Dosage, on the other hand, refers to the specific amount of the medication prescribed for a single administration or over a specific time period, which takes into account the strength to determine how much of the medication a patient should take. Essentially, strength indicates how potent the medication is, while dosage dictates how much of that strength is administered to achieve the desired therapeutic effect.
