💡 PRO TIP

Injecting insulin at room temperature can make injections feel smoother and less painful than using cold insulin straight from the fridge.

💡 Many people let a new pen or vial sit out for a few minutes before using it — just enough to take the chill off.

🚫 Keep insulin away from extreme temperatures — don’t leave it in a hot car or near a sunny window.

❄️ Never freeze insulin — freezing damages it and makes it ineffective.

🔥 Never heat insulin — especially not in a microwave. It’s medicine, not a snack!
