What causes dizziness and nausea while on Tylenol?
Patient: My husband has been taking anywhere from 10-20 Tylenol PM or Advil PM daily for the last 6 months. A few days ago he became extremely dizzy with nausea/vomiting. He went to the ER and they checked him thoroughly (CT scan, EKGs, labwork, etc.) and found nothing wrong. He did not tell them about the PM meds he s been taking. Is it possible these pills were the cause of his dizziness and nausea/vomiting? He has not had them as far as I know for about a week now but still complains of some dizziness though not nearly as bad. Doctor: Hello and Welcome to ‘Ask A Doctor’ service.  I have reviewed your query and here is my advice.   Tylenol PM long term consumption may cause drug induced liver injury, also possible that nephrotoxicity and labyrinthine injuries. This dizziness may be due to BPPV or hypotension or hypoglycemia or infection etc. Until examination is done it is difficult to say what it is. Avoid high risk activities, use water vapor inhalation and salt water gargling thrice a day. Use tablet Vertin thrice a day for five days. If symptoms not improved please consult your ENT specialist he will examine and treat you accordingly.  Hope I have answered your query.  Let me know if I can assist you further.
