Insulin controls blood sugar levels. Diabetics don’t have enough insulin or in some cases  the body does not know how to use it properly. Over time, excessive blood sugar levels might cause serious health problems.

Insulin controls blood pressure in type 1 and 2 diabetics. The objective of diabetic treatment is to maintain a healthy blood sugar level. If you’re new to insulin, here’s what you should do and what you don’t to keep your diabetes under control.

Insulin Do's

1. Changing The Injection Location For Insulin

When you inject in the same spot every time, there is a risk of developing hard lumps and fat deposits. To avoid this, the injection should be administered at different locations within the site.

2. Take 15 to 30 Minutes Before A Meal

Consider taking insulin 15 to 30 minutes after a meal. This will help control blood sugar effectively. Do not wait too long after a meal to take insulin as it could pull down blood sugar drastically. 

3. Each Usage Requires A New Needle

After a while, the syringe and pen needles get dull. Each time you inject insulin, use a new needle because sharper needles induce less discomfort.

4. Use The Recommended Insulin Dosage

It is critical to use the correct dose of insulin. When extracting insulin from the syringe, the black plunger’s tip should be aligned with the number. To achieve the proper dosage while using a pen, rotate the dial.

5. Travel Smartly

Carry additional insulin syringes, needles, pens, and pump batteries with you when you travel.


Insulin Don'ts

1. Avoid Injecting At Specific Locations

Avoid injecting near the belly button, moles, or scars because the tissue there is hard, preventing proper insulin absorption.

2. Store In The Right Temperature

Don’t keep unopened insulin in a warm temperature. Keep it between 2 and 8 degrees Celsius in the refrigerator. However, don’t keep the opened vial in the refrigerator. Keep it at room temperature in a cool, dry location away from direct sunlight.

3. Avoid Using Expired Medicine

Do not use the insulin that is beyond its expiry date. You should discard a month-old insulin bottle.

4. Don’t Take Any Extra Insulin

Excessive insulin reduces blood sugar levels. Monitor your glucose levels throughout the day if you can’t remember whether you took your insulin dose or if you think you took a lower dose than your doctor recommended. Do not increase your insulin dose without consulting your doctor.

Insulin Precautions

Make sure you consult your diabetologist if you face the following post insulin shot.

  • Allergic reaction
