Influence of vitamin C supplementation on oxidative and immune changes after an ultramarathon
For weekly injectable formulations like semaglutide and tirzepatide , the exact hour matters less than consistency
Practical management strategies include: Setting reminders for both tirzepatide injections and antibiotic doses to ensure adherence Keeping a symptom diary noting glucose readings, medication times, and any adverse effects Having a sick-day management plan that includes glucose targets, ketone testing, and when to contact your provider Maintaining adequate carbohydrate intake even if appetite is reduced, using easily digestible options if needed Contact your healthcare provider if you experience persistent hyperglycemia (blood glucose consistently above 250 mg/dL), positive ketones, signs of diabetic ketoacidosis (excessive thirst, frequent urination, fruity breath odor, confusion), or inability to maintain oral intake due to severe nausea or vomiting
