Bacterial Infection
"16 year old son was prescribed 1000mg twice a day for sinus infection. He&#039;s been sick 4 weeks and they thought it was mono, he&#039;s already so tired all he wants to do it sleep. Plus cough and congestion. Mono blood test results came back negative so they prescribed him this super heavy dose of cephalexin for 10 days to treat a &quot;possible&quot; sinus infection. I don&#039;t even know if this is good or bad for my son to take so I&#039;m reading reviews. I have not seen one review where they were prescribed 1000mg twice a day. So I&#039;m going to give my son 500mg twice a day and see if it helps. Along with a probiotic as he has always had stomach intestinal issues. Haven&#039;t given him any yet but will keep y&#039;all posted. Thank you all for sharing your experiences!"
