What is an active ingredient?

An active ingredient is what causes the effect of the medication and is the reason you take it. Medications may have a range of ingredients, but they always have one or more active ingredients. The strength of the medication is how much of the active ingredient is in the medication (in each tablet or capsule). The name and concentration of the active ingredient is always listed on the packaging of the medication.
