Can Dalacin C cause depression? I have a friend whose right big toe had been amputated recently. He was prescribed cloxacillin & clindamycin (dslacin c). He's not so worried about his toe because he can still function like a normal/regular person even w/o it. But while he's taking antibiotics, his family noticed he's unusually depressed....feeling so down....they are suspecting it's a side effect of his medication. What are your thoughts on this matter?
