How strong is the drug effect?

Topical steroids are grouped into five categories depending on their strength.
Topical steroids are classified into five categories according to their strength of action: “weak,” “mild,” “strong,” “very strong,” and “strongest.” Among these, topical steroids classified as "very strong" and "strongest" are sold only as prescription drugs, which require a doctor's prescription.
Non-prescription drugs include three categories: “weak,” “mild,” and “strong.” Betamethasone valerate, contained in Rinderon Vs Ointment, Cream, and Lotion, is classified as “strong,” a strong steroid among non-prescription drugs.
