Ok my friend has just owned up to taking 420mg of prozac 4 days ago she had no symptoms so obviously left it at that. What worries me she has had the doctor out today because she has tonsilitis and a rapid heart rate. The doctor told her its well known to have a fast heart rate when ill with a virus. Is it down to the throat infection or down to the prozac as it was like 4 days ago she took the overdose. I have tried telling her to tell the doctor but as this is not her 1st attempt she said they will most probably commit her which she said she couldnt bear so obviously i have to go with her wishes.
