My elderly father is a diabetic and heart patient currently taking Humansulin 30/70, Galvus Met 50/500, Dianorm OD 60, Cardarone-X, Carca-CR-20, and Telecad-20. After a recent fall, he was prescribed an antibiotic and a steroid for pain. Today, his blood sugar is unmeasurably high on the glucometer, even after administering extra doses of Actrapid and Humansulin. Could the recently prescribed steroid be causing this extreme spike in his blood sugar, and what immediate medication adjustments or treatments should we provide to bring it down safely?

Yes, the recently prescribed steroid is almost certainly the cause of this extreme spike. Steroids significantly increase insulin resistance, rapidly raising blood glucose. An unmeasurably high reading is a critical medical emergency that puts him at risk for life-threatening complications like Hyperosmolar Hyperglycemic State (HHS). Do not administer further extra insulin doses at home, as this can cause dangerous, delayed hypoglycemia. Please take your father to the nearest emergency room immediately. He requires urgent professional medical evaluation, intravenous hydration, and closely monitored insulin therapy to safely lower and stabilize his blood sugar levels.

I have a history of diabetes, and I am taking Gemer P2, Huminsulin 30/70, Tenglyn, and Evion LC. For the last two days, I have had pain and a stretching sensation in my arm muscles. My BP is 142/92 mmHg, and fasting sugar is 120 mg/dL. Could these symptoms be related to my diabetes, blood pressure, or medications?

Pain and a stretching sensation in the arm muscles can occur for several reasons in a person with diabetes. Your fasting sugar of 120 mg/dL is reasonably controlled, but diabetes can still sometimes cause muscle pain, nerve irritation, or reduced blood circulation. Mildly raised blood pressure at 142/92 mmHg is unlikely to directly cause arm muscle pain, but it should be monitored regularly. Your medicines may also play a role. Pioglitazone in Gemer P2 may occasionally cause muscle discomfort or fluid retention. Huminsulin 30/70 (Human insulin) may rarely cause low potassium levels, which can lead to muscle cramps or weakness. Vitamin supplements, such as Evion LC, are usually not harmful, but interactions and individual reactions can vary. You should also consider simple causes such as muscle strain, poor posture, dehydration, or a vitamin deficiency. However, if the pain increases, weakness develops, swelling appears, or you have chest discomfort or breathlessness, consult your doctor immediately. Your doctor may advise blood tests for electrolytes, vitamin levels, kidney function, and muscle enzymes if symptoms continue.

I use Wosulin 30/70 insulin for diabetes and will be traveling to Dubai, where Humulin 30/70 is available. Are these two medicines the same, and can I safely use Humulin 30/70 as a substitute?

Yes, Wosulin 30/70 and Humulin 30/70 are highly similar. Both contain the same ratio of 30% fast-acting and 70% intermediate-acting insulin. Since they are equivalents, Humulin 30/70 can be used as a substitute while you are in Dubai. However, because they are made by different manufacturers, minor variations in how your body absorbs them can occur. I highly recommend monitoring your blood glucose levels more frequently during the first few days of the switch. It is also wise to consult your doctor before traveling to confirm the transition plan and ensure your dosage remains appropriate.
