All inhalers should be used according to the directions on the labels that come with the product. Though these are safe products, they are not intended for use by everyone, and can have harmful interactions and side effects if used improperly.

When using an asthma inhaler, make sure you understand from your physician the type of medication you are taking and how it affects you. Also, there are many drug interactions, such as if you are taking a MAOI inhibitor, that can be harmful if used in conjunction with an asthma inhaler.

Even the over-the-counter inhalers should be used with caution. Keep out of reach of children unless directed by your physician, do not use for a prolonged period of time and do not exceed the recommended dosage.

Inhalers are safe and effective for many conditions and situations, but you should be smart and talk to your doctor, especially if you are pregnant or nursing or have any sort of medical condition that could be affected by an inhaler.
