Insulin in Africa: What Every Diabetic Patient Needs to Know Right Now

Insulin saves lives. But in Africa, many diabetics are either afraid of it, can’t access it, can’t afford it, or don’t know how to use it properly. This article is for every diabetic on the continent who has ever felt confused, scared, or alone when it comes to insulin.

What Is Insulin and Why Do Some Diabetics Need It?

Insulin is a hormone your pancreas produces to help your cells absorb glucose from your blood. Without it, your cells starve while your blood sugar stays dangerously high.

People with Type 1 diabetes produce no insulin and must inject it to survive. People with Type 2 diabetes may eventually need insulin if oral medications can no longer control their blood sugar effectively.

Types of Insulin

Rapid-Acting Insulin

Starts working within 15 minutes. Used just before or with meals to manage the blood sugar spike from eating. Examples: NovoRapid (Aspart), Humalog (Lispro), Apidra (Glulisine).

Short-Acting (Regular) Insulin

Takes 30-60 minutes to start working. Usually injected 30 minutes before meals. Example: Actrapid, Humulin R.

Intermediate-Acting Insulin

Works for 12-18 hours. Often taken twice daily. Example: NPH insulin (Insulatard, Humulin N).

Long-Acting (Basal) Insulin

Provides a slow, steady release over 24 hours. Taken once daily, usually at bedtime. Examples: Lantus (Glargine), Levemir (Detemir), Tresiba (Degludec).

How to Inject Insulin Safely

1. Always wash your hands with soap and water before handling insulin
2. Check your insulin — never use cloudy rapid-acting insulin or expired insulin
3. Rotate your injection sites — abdomen, thighs, upper arms, or buttocks
4. Pinch the skin gently and inject at a 90-degree angle (or 45 degrees if you’re very lean)
5. After injecting, hold the needle in for 10 seconds before removing
6. Never reuse needles — it increases infection risk and hurts more

Storing Insulin in African Heat

This is critical. Insulin degrades in heat above 25°C — and in Accra, Lagos, or Nairobi, temperatures regularly exceed this. Here’s what to do:

• Unopened insulin: Store in the refrigerator (2-8°C). Never freeze.
• Opened insulin (in use): Can stay at room temperature (below 25°C) for 28-30 days depending on the brand. Keep out of direct sunlight.
• During dumsor / power cuts: Use an insulated cooling case (Frio wallet) that uses evaporation — no electricity needed. Available at most medical supplies shops.
• Signs of damaged insulin: Cloudy appearance (in normally clear insulin), lumps, or colour change. If in doubt, do not use it.

What If You Can’t Afford Insulin?

This is a real crisis for many Africans. Some options:

• Ask your doctor about generic alternatives — often much cheaper than branded insulin
• Contact your national diabetes association for support programmes
• Ask at government hospitals — subsidised insulin is sometimes available
• Join our Telegram community — members often share information about affordable sources in your city

Insulin is not a luxury. It is a right. Every person with diabetes who needs insulin deserves access to it. We will keep fighting for that at The Diabetes Voice.
