Can you give a 7 yr old clindamyacin to help get over a 9 day old fever/cold, cough has gotten stronger. How long does a viral infection last?

A worsening cough and fever could be an indication of a bacterial super-infection such as pneumonia, sinusitis or bronchitis. You should have the child seen by their doctor. Clindamycin is an antibiotic which works for some infections, but not for others, so an exam is very important so he/she gets the correct treatment. Do not use the Clindamycin unless instructed to by the child's doctor. ...Read more
