My 16 year old daughter fainted yesterday at school about 30 minutes after taking Bayer asprin. Today, before giving blood at her school blood drive, a nurse checked her blood pressure and it was 90/62 (they let her give blood anyway). After giving blood, she felt very weak and could hardly stand up. Could her fainting be from the asprin or could it be a side effect of her low blood pressure?
Hello, Would explain fainting is usually related to low blood pressure values. It is not related to Aspirin.  I would just recommend taking plenty of water and increasing salt intake if her blood pressure values continue to stay low.  Hope I have answered your query. Let me know if I can assist you further.
