Son aged 3 has just been prescribed penicillin for tonsilitis.  He has had one dose and then gone to bed as normal.  However he has since woken up 3 times in 4 hours in a cold sweat and has just had a nose bleed.  Is such a reaction normal, unrelated or cause for concern (I note that the tonsiltis had been causing cold sweats before but not as often)
Thanks for asking. I have gone through your question and I understand your concern.  Your son who is 3 years old has suffered with tonsillitis as being treated with penicillin. As you said, and he woke up 3 times in 4 hours with cold sweat and nose bleed, you are worried.  There are no relation between cold sweat and the penicillin sometimes its due to fever which is coming down. In my opinion is no case to worry.continue the treatment, wish you healthy family thank you
