我大致查了一下：

“Amoxicillin belongs to a group of antibiotics called Penicillins. If you are allergic to Penicillins then you are more likely to be allergic to a group of antibiotics called Cephalosporins of which Cephalexin is a member. Cephalexin should be avoided in a penicillin allergic patient. Antibiotics such as clarithromycin, doxycycline and erthyromycin may be safe alternatives for you.”

大家还是注意一下。特别是青霉素过敏的人。

所有跟帖： 

• 医生开处方前都会问，对什么药过敏，包括青霉素类过敏。 -pickshell- ♀ (0 bytes) () 03/04/2023 postreply 12:48:10

• 一般讲青霉素过敏的病人中5-10%同时对头孢过敏，临床原则上尽量不用。但不是禁忌，要看具体情况。 -老道- ♂ (0 bytes) () 03/05/2023 postreply 15:58:01
