Overview

Insulin helps the body regulate blood sugar properly. When the body does not have enough insulin, or when insulin does not work well enough, sugar remains too high in the blood. This medicine helps sugar move into the body's cells so it can be used for energy.

Ibrahim's pharmacy advice

I often explain it like this: insulin is the key that opens the door so sugar can enter the body's cells. If that key is missing or does not work properly, the sugar stays in the blood instead of being used by the body. So insulin is not just an injection. It is an important daily treatment that helps the body function properly. The most important things are correct use and regular blood sugar monitoring.

Use

  • Insulin is used to treat diabetes.
  • It helps sugar move from the blood into the body's cells so blood sugar can come down.
  • Some types of insulin act quickly, while others work more slowly and for longer.

Dosage and Ibrahim's advice

  • Insulin dose is individual and depends on the type of insulin, food, activity, and blood sugar level.
  • Always follow the plan from your doctor or diabetes nurse.
  • Change injection site to avoid lumps or skin changes.
  • For some insulins, timing is closely linked to meals, so correct timing is very important.

Side effects

  • The most important side effect is low blood sugar.
  • Some people may gain weight or notice redness and itching at the injection site.
  • If you often inject in the same place, the skin may become thickened or uneven.

Drug interactions

  • Some medicines, such as steroid treatment, certain diuretics, and beta blockers, may change the need for insulin.
  • Illness, infection, or major changes in diet and exercise can also affect blood sugar.
  • Tell your doctor or pharmacist about all medicines you use, and check blood sugar as advised.

Important warnings

  • Signs of low blood sugar may include sweating, shaking, hunger, palpitations, confusion, or dizziness.
  • If blood sugar drops too low, take fast sugar according to your treatment plan.
  • Do not drive if you feel affected by low blood sugar.
  • If you vomit a lot, cannot eat, or become seriously ill, the insulin plan may need review.

Ramadan and fasting

  • Insulin can usually be used during Ramadan, but the treatment plan should be adjusted beforehand.
  • Talk with your doctor or diabetes team before Ramadan.
  • If blood sugar falls too low, you should break the fast for safety.
  • Monitoring blood sugar during fasting is very important.

Food and drink

  • If you use rapid-acting insulin, meal timing is important.
  • Always keep fast sugar nearby, such as glucose tablets or some juice, in case blood sugar drops.
  • The amount of carbohydrate in meals directly affects insulin needs.

Storage

  • Unopened insulin is usually stored in the refrigerator, but must not be frozen.
  • Insulin or pens in use can often be stored at room temperature for a limited time, as stated on the package.
  • Protect from heat and direct sunlight.
  • Always read the instructions for the exact insulin you are using.
