这个是激素类止痒药。

其他都是保湿类的，也就无所谓药不药了。

Polyclinic的医生还给我开了一大罐尿素霜，勾起了我童年的回忆。

你说的非但不能通用并且含有的激素更猛, 中间两个含有抗菌成分。

Elomet (mometasone) Tobradex (Tobramycin/dexamethasone) Fucicort (Fusidic acid/betamethasone) Efficort (Hydrocortione aceponate)

Low-potency steroids are the safest agents for longterm use, on large surface areas, on the face or areas of the body with thinner skin, and on children. More potent agents are beneficial for severe diseases and for areas of the body where the skin is thicker, such as the palms and bottoms of the feet. High- and ultra-highpotency steroids should not be used on the face, groin, axilla, or under occlusion, except in rare situations and for short durations.

激素类用药都是先从low potency的往上走，这个是基本的常识。

这个和公立私立无关。
