Here's How to Build a Complete First-Aid Kit for 2025

Emergencies can happen when you least expect them. To help prepare for the unexpected, having a well-stocked first-aid kit can give you a critical advantage for handling minor injuries, illnesses or unexpected situations.

We break down why first-aid kits are essential, what they should contain and how to prepare for various scenarios.

Why do I need a first-aid kit?

It will bring you peace of mind and the ability to help in emergencies. Having access to basic medical supplies, whether you're at home or traveling, can make a huge difference. Properly prepared kits can help you manage minor injuries until professional help is available or prevent complications from worsening.

Where do I store my first-aid kit, and how do I store a first-aid kit safely?

Place first-aid kits in locations that make sense for your lifestyle. Common places include your home, car, and carry-on bag when traveling. Just as important as having the kits is maintaining them. Check your kits regularly to replace expired products or batteries and make sure they're fully stocked. For safety, always keep kits out of children's reach.

Tips for staying prepared

How often should I check my first-aid kit? Set a reminder to inspect your kits at least twice a year. Replace expired items and make sure everything works.
How should I customize my first-aid kit? Consider your household's unique health conditions or allergies and include additional supplies as needed.
What can further keep me prepared: Familiarize yourself with basic first aid techniques, like CPR or the Heimlich maneuver, so you can confidently handle emergencies.
What should I include in a travel first-aid kit? Your travel first-aid kit should be lighter than what you keep at home.

Emergencies may be unpredictable, but preparation doesn't have to be. A well-stocked first aid kit makes you feel confident and ready to face most minor injuries and illnesses.
