How should a patient with hypertension manage their usual medications when illness causes a significant reduction in food and water intake?

Do not stop, double up, or change the dose of your medications on your own. Keep a record of food and fluid intake, vomiting or diarrhea, blood pressure, urine output, and all medications taken. Contact your prescribing doctor, pharmacist, or healthcare facility as soon as possible for individualized advice. Seek emergency care if you experience fainting, abnormal mental status, persistent inability to eat or drink, or significant difficulty breathing.
