One of the best tools for managing asthma is a controller medicine that has a steroid.

When taken correctly, inhaled steroids have been proven to reduce asthma symptoms and usually don't have side effects. But people who are struggling with asthma may be afraid to take inhaled steroids because of some common myths.

So let's see if we can bust these myths and turn them into facts.

Myth #1: No matter how you take steroids, the side effects are the same.

NOT TRUE. The inhaled steroids in asthma medicine go just to the site of the problem-your lungs. This is different than the kind of steroids you inject or take in a pill which go throughout the body and are riskier.

Myth #2: Taking inhaled steroids will make you grow muscles...and hair.

NOT TRUE. The steroids in asthma medicine are a different type of steroid than the muscle-building, hair-growing kind.

And because you inhale the medicine, it goes right to your lungs where it's needed.

Myth #3: You can control your asthma using only your quick-relief inhaler.

NOT TRUE. Many people will only find relief and get good control over their asthma by using controller medicine.

Myth #4: Taking inhaled steroids will stunt your growth.

NOT TRUE. For children, there may be a small change in growth from inhaled steroids. But for most people, this is made up for by the improved ability to breathe because of the positive effects of the medicine.

So when it comes to managing your asthma, bust the myths about inhaled steroids and use controller medicine to live better for the long term.
