Frequently asked questions
Is dexamethasone stronger than prednisolone?
Yes — it is more potent and longer-acting, so much smaller doses are used. Your doctor chooses based on the condition.
Is dexamethasone misused for weight/skin?
Yes — unsupervised use for weight gain or fairness is dangerous and can cause serious harm. Only use it as prescribed.
