Control drugs for asthma are drugs you take to control your symptoms of asthma. You must take them every day for them to work. You and your doctor can make a plan for the drugs that work for you. This plan will include when you should take them. It will also include how much you should take.

You may need to take these drugs for at least a month before you start to feel better.

Take them even when you feel okay. Take enough with you when you travel. Plan ahead. Make sure you do not run out.

Inhaled corticosteroids help keep your airways from swelling up. This helps keep your asthma symptoms away.

Inhaled steroids are used with a metered dose inhaler (MDI) and spacer.

You should use an inhaled steroid every day, even if you do not have symptoms.

After you use it, rinse your mouth with water, gargle, and spit out.

If your child cannot use an inhaler, your doctor will give you a drug to use with a nebulizer. This machine can turn liquid medicine into a spray. This lets your child breathe the medicine in.

Your doctor may ask you to take both a steroid drug and a long-acting beta-agonist drug.

It may be easier to use an inhaler that has both drugs in them.
