Know the signs of a flare-up. You should have an action plan in place so you and your loved one know exactly what to do when one occurs.
Knowing how to reach a healthcare provider when needed is crucial. Create an emergency contact list so you can get help fast if need be. This should include applicable information for school, work, home—even vacation—whatever situations apply.
Make sure you are familiar with any medications your loved one is taking. You should know whether the meds are for long-term prevention or quick-acting relief. Become familiar with the correct dose, as well as when it needs to be taken. Likewise, you need to know which medication is appropriate for a given situation, as well as how to administer it.
