Insulin is the hormone that lowers blood sugar. It is essential in type 1 diabetes and used in type 2 when other medicines are not enough. Doses are individual and adjusted over time — never fixed.
Match dose to food and activity; never skip meals after a dose
When to see a doctor urgently
Severe hypoglycaemia: confusion, fainting or fits — emergency (needs fast sugar/glucagon)
Very high sugar with vomiting or drowsiness
Doses are a general reference, not a prescription. Doses shown are typical adult/paediatric references and vary with age, weight, kidney/liver function and the exact product. Paediatric doses are usually weight-based and must be set by a doctor. MedDroid cannot prescribe — always confirm insulin and your dose with a doctor or pharmacist and the leaflet inside the pack.
Frequently asked questions
Does insulin have a standard dose?
No — it is always personalised in units and adjusted to your blood-sugar readings, meals and activity by your diabetes team.
Does starting insulin mean my diabetes is worse?
Not necessarily. Insulin is a normal, effective step when the body needs more help — it is a tool, not a failure.
