Hello,
Adderall can cause anorexia,weight loss and abdominal pain but it causing taste of blood in mouth is not documented.You are having dysguesia i.e bitter or bad taste in mouth. It can be due to dental caries, gastro-esophageal reflux disease,sinusitis causing post nasal drip,salivary glands infection,pharyngitis or strep infection, medications like antibiotics, vitamins and antidepressants, poor oral hygiene, copper or lead toxicity and Sjogren’s syndrome.Can you identify any of these?
