As a diabetic, you must choose over-the-counter cold medications carefully. 1. Avoid Decongestants: Drugs like pseudoephedrine can raise both blood sugar and blood pressure. Use saline nasal sprays instead. 2. Go Sugar-Free: Standard liquid cough syrups and lozenges contain high amounts of sugar. Always look for diabetic-safe, sugar-free options. 3. Pain Relief: Acetaminophen (Tylenol) is generally safe for fever and aches, but consult your doctor if you have kidney complications before taking NSAIDs like ibuprofen. 4. Monitor Glucose: Illness stresses your body, which can spike blood sugar levels. Check your glucose more frequently, stay hydrated, and consult your doctor if your readings remain high.

You should see a doctor to identify the underlying cause, which could be allergies, a sinus infection, or a nasal blockage. Keep your nasal passages clear with gentle saline rinses, stay hydrated, and avoid irritants such as smoke or strong perfumes. If you experience severe difficulty breathing, seek medical attention immediately.

For immediate relief from throat irritation, try warm saline gargles, steam inhalation, and anesthetic throat lozenges. Since Paracetamol and Cofdex didn't help, a saline nasal spray can safely ease nasal discomfort. For long-term immunity and to prevent frequent colds, consider daily supplements of Vitamin C, Vitamin D3, and Zinc, alongside a balanced diet and consistent sleep. Please do not start antibiotics on your own. If your symptoms persist for more than a week, or if you develop a high fever or difficulty swallowing, please consult a doctor for a physical examination to rule out a secondary bacterial infection.
