Insulin in Nigeria: Types, How to Use It, and What It Costs

← Back to all articles

What Is Insulin and Who Needs It?

Insulin is a hormone that helps your body control blood sugar. When you eat, your food breaks down into glucose, which enters your bloodstream. Insulin acts like a key that opens your cells to let glucose in so it can be used for energy. Without enough insulin — or if your body cannot use it properly — blood sugar builds up in your blood, leading to hyperglycemia (high blood sugar).

In Nigeria and worldwide, millions of people depend on insulin injections to manage type 1 diabetes, type 2 diabetes, and gestational diabetes. If your doctor has prescribed insulin, it means your pancreas is not making enough insulin on its own, or your body has become resistant to it, and lifestyle changes or oral medications alone are not bringing your blood sugar under control.

Many people fear starting insulin because they think it means their diabetes is "worse" or that they have "failed" diet and exercise. This is a common myth. Starting insulin is a sign that you are taking your health seriously and want to prevent complications. Insulin is one of the safest, most effective tools we have to manage diabetes in Nigeria.

Types of Insulin Available in Nigeria

Not all insulins are the same. They differ in how fast they work, when they peak, and how long they last. Your doctor will choose the type that fits your lifestyle and blood sugar patterns.

Short-Acting (Rapid-Acting) Insulin

Brands in Nigeria: Actrapid, Humulin-R, Novorapid

These insulins work quickly — within 15–30 minutes — and peak around 1–3 hours. They last about 3–6 hours total. Use them with meals to bring down the blood sugar spike from food. Many people inject short-acting insulin just before or right after eating. Short-acting insulins are the most affordable in Nigeria, costing around ₦4,000–₦8,000 per vial.

Long-Acting (Basal) Insulin

Brands in Nigeria: Lantus, Levemir, Tresiba

These provide steady background insulin throughout the day and night, mimicking what a healthy pancreas would do naturally. They take a few hours to kick in and work for 24 hours or longer. Long-acting insulins are usually injected once or twice daily. They help keep your fasting blood sugar stable and prevent midnight low blood sugars. Long-acting insulins are more expensive — ₦8,000–₦15,000 per vial — but many people need only one injection per day.

Premix Insulin

Brands in Nigeria: Mixtard 30/70, Humulin 70/30, Novomix

These combine short-acting and long-acting insulin in one pen or vial — for example, Mixtard 30/70 contains 30% short-acting and 70% long-acting insulin. Premix insulins simplify life for people who want fewer injections. They work well for many people but are less flexible if you need to adjust doses based on meals. Premix insulins in Nigeria cost ₦4,500–₦10,000 per vial.

How to Inject Insulin: Step-by-Step Guide

Insulin injections are simple once you learn the technique. Most people find it easier than they feared. Here is how to do it safely:

Step 1: Gather Your Supplies

• Your insulin vial or pen
• Sterile syringes or needles (appropriate gauge for insulin — usually 31G is fine)
• Alcohol swabs or spirit
• A sharps container or sealed bottle for used needles
• A clean, flat surface like a table

Step 2: Prepare Your Insulin

If using a vial:

• Check the expiration date
• Look at the insulin — it should be clear (unless it is a cloudy premix, which should be mixed by rolling gently, not shaking)
• Let it reach room temperature if it was cold

Step 3: Draw Your Dose

• Wipe the rubber top of the vial with an alcohol swab and let it dry (do not blow on it)
• Pull the plunger of your syringe back to match the number of units your doctor prescribed
• Push the needle through the rubber top and inject the air into the vial (this makes it easier to withdraw insulin)
• Hold the vial upside down and pull back the plunger slowly to draw out your dose
• Check for air bubbles — if you see bubbles, push them back into the vial and redraw

Step 4: Choose Your Injection Site

You can inject insulin into:

• Abdomen (belly): Fastest absorption — inject at least 2 cm away from your belly button
• Thighs: Medium absorption speed — outer front or side of thigh
• Arms: Slowest absorption — back of the upper arm, if you can reach
• Buttocks: Slow and steady absorption

Rotate your injection sites to prevent lipohypertrophy (lumps that reduce insulin absorption). Keep a notebook or use AFYA app to track where you inject each time.

Step 5: Inject

• Pinch the skin at your injection site
• Insert the needle at a 90-degree angle (straight in) with a quick, confident motion
• Push the plunger slowly and steadily until all insulin is delivered
• Count to 5, then slowly withdraw the needle
• Release the pinched skin

Step 6: Dispose Safely

• Never reuse needles — they become dull and painful
• Place used needles in a sharps container or sealed bottle marked "used needles"
• When the container is full, seal it and discuss safe disposal with your local health facility or pharmacy

Storing Insulin in Nigerian Heat and During NEPA Blackouts

Nigeria's tropical climate and power cuts make insulin storage a real challenge. Insulin spoils if it gets too hot or freezes. Here is how to protect it:

Unopened Insulin Vials and Pens

• Store in a cool, dark place away from direct sunlight
• Keep at room temperature (15–30°C) — you do not need a fridge if your home stays within this range
• Avoid windowsills, direct sunlight, and areas near cookers or heat sources

During NEPA Blackouts

• Use an insulated cooling bag or cooler with ice packs — wrap the bag in a damp cloth to keep it cool longer
• Alternatively, soak insulin vials in a container of cool water (not ice water) if you do not have ice packs
• Do not let insulin freeze — if it does, discard it

Once You Have Opened a Vial

• Use within 4 weeks
• Keep at room temperature (you can now keep it out of the fridge)
• Write the date you opened it on the vial label with a permanent marker
• Throw away after 4 weeks even if insulin remains

Check for Spoilage

Before each injection, look at your insulin. Clear insulin should be transparent. If it looks cloudy when it should be clear, or if you see crystals, particles, or discoloration, discard it — it has spoiled.

Cost of Insulin in Nigeria

The price of insulin varies widely depending on type, brand, and where you buy it. Here is a realistic breakdown:

Prices are higher in private pharmacies than at public health facilities or NHIS-accredited hospitals. If you are enrolled in the National Health Insurance Scheme (NHIS), check your coverage — some plans include insulin. Government tertiary hospitals in Lagos, Abuja, Kano, and other major cities sometimes stock insulin at subsidized rates.

If cost is a barrier, talk to your doctor about alternatives. Some people manage well on older insulin types that are cheaper, or on fewer injections per day. Never skip insulin to save money — the complications of uncontrolled diabetes are far more expensive to treat than insulin itself.

How AFYA Helps You Track Insulin and Stay in Control

Managing insulin requires discipline: remembering doses, timing injections, rotating sites, and monitoring blood sugar. AFYA's AI health companion makes it easier by helping you log insulin doses, get reminders, track patterns, and answer questions about your diabetes 24/7.

With AFYA, you can:

• Log your insulin injections and blood sugar readings in one place
• Set reminders for your insulin times so you never miss a dose
