Having proper first aid supplies nearby prepares you for medical emergencies, whether for a simple cut or accidental poisoning. Besides keeping one inside the home, there should also be a first aid kit in the car. If you don't want to buy a pre-made first aid kit, you can gather the medical items and make your own kit.
Find a container to use for your first aid kit. It will need to have a lid that fits securely. Before selecting the container for the car's first aid kit, take it to the car and determine where it will be stored. Some vans have storage compartments; if your vehicle doesn't have one, slide the container in the glove box or under the seat. To make sure the lid stays on securely, wrap a large rubber band around the container.
Gather items that the first aid kit should have. These items would include sterile gloves, antibiotic hand cleansers, alcohol or hydrogen peroxide, cotton balls, cotton swabs, scissors, tweezers, antibiotic ointments, hydrocortisone cream, syrup of ipecac and a variety of adhesive bandages.
Include other items that are important but not necessary. These include pain killers--both adult and children types--a thermometer, ammonia ampules, elastic bandages, facial tissues, eye drops, hay fever or sinus medications, antacids, laxatives and diarrhea medication.
Add items that are convenient but not necessary. These include cough drops, lip balm, petroleum jelly, safety pins and an air sickness bag. For teenage girls and women, include a small assortment of sanitary products, although these can be stored in a separate container.
Buy a small first aid manual to keep in the first aid kit. Write down emergency phone numbers, including Poison Control, on the inside cover. Write down all pertinent medical information for each family member, including vaccination history, allergies and special health issues, and put it in the first aid kit. In the event of a medical emergency that requires a trip to the hospital, you will have this information handy.
