Asthma Medications

Are There Over-the-Counter Asthma Drugs?

Yes. The most common over-the-counter asthma drugs are Primatene Mist and Bronkaid. They both work like a bronchodilator, relaxing the muscles around the airways. They provide short-term relief (20-30 minutes), but do not control asthma symptoms or prevent asthma attacks. People with high blood pressure, diabetes, thyroid disease, or heart disease should not take Primatene Mist or Bronkaid.
Unfortunately, many people misuse or overuse these asthma treatments. The over-the-counter drugs are not meant for long-term use, yet some people use them every day to relieve asthma symptoms. Because they do not control asthma, people who take them may not be receiving proper treatment of their asthma.
If you are using an over-the-counter asthma drugs and are still experiencing frequent asthma symptoms, talk to your doctor. And if you are taking prescribed asthma drugs but are using over-the-counter medications occasionally, tell your doctor this as well. You do not want to be taking more medicine than you need.

Can Allergy Shots Be Used to Treat Asthma?

Some recent studies have shown that when you give allergy shots (immunotherapy) to children with allergies, not only do their allergy symptoms improve, but they are also less likely to develop asthma. Also, since many cases of asthma are triggered by allergies, it makes sense that if you control the allergies, you will have fewer asthma attacks.
Ask your doctor if you are a candidate for allergy shots.

How Often Will I Have to Take Asthma Drugs?

Asthma can't be cured. How often you need to take your asthma drugs depends on how severe your asthma is and how frequently you have symptoms. For example, if your asthma symptoms occur only during the time of the year when your allergies act up, then you may only have to take medications to control your symptoms during that time. However, this is somewhat unusual, and most people with asthma need to take medications every daily.

Asthma Medication Guidelines

Asthma medications are the foundation of good asthma control. Learn all you can about your medications. Know what medications are included in your asthma action plan, when these drugs should be taken, their expected results, and what to do when they fail. Here are some general guidelines to keep in mind:
  • Never run out of asthma medication. Call your pharmacy or doctor's office at least 48 hours before running out of your asthma medications. Know your pharmacy phone number, prescription numbers, and drug names and doses so that you can easily call for refills.
  • Refer to your asthma action plan when deciding how or when to use asthma drugs. This plan is designed so you achieve the best possible asthma control. Make sure you understand and can follow the plan.
  • Wash your hands prior to preparing or taking asthma drugs.
  • Take your time. Double-check the name and dosage of all your asthma medications before using them.
  • Keep your asthma drugs stored according to the instructions given with the prescription.
  • Check liquid medications often. If they have changed color or formed crystals, throw them away and get new ones.
  • Inform your doctor about any other medications you are taking. Some drugs can affect the actions of your asthma medications when taken together. Most asthma medications are very safe. However, side effects can occur and vary depending on the medication and dose. Ask your doctor or pharmacist to describe medication side effects. Report any unusual or severe side effects to your doctor immediately.

Asthma Medications

Quick-Relief Asthma Drugs

These asthma drugs are used to provide prompt relief of asthma attack symptoms (cough, chest tightness, and wheezing -- all signs of airway bronchoconstriction).
These asthma drugs include:
  • Short acting beta-agonists (bronchodilators that are the drug of choice to relieve asthma attacks and prevent exercise-induced asthma symptoms)
  • Anticholinergics (bronchodilators used in addition to short-acting beta-agonists when needed or as an alternative to these drugs when needed)
  • Systemic corticosteroids (an anti-inflammatory drug used in an emergency to get rapid control of the disease while initiating other treatments and to speed recovery)

Inhalers, Nebulizers, and Pills as Asthma Medicine

Asthma medicines can be either inhaled, using a metered dose inhaler, dry powder inhaler, or a nebulizer, or taken orally, either in pill or liquid form. A newer type asthma medication called Xolair is given by injection just under the skin.
Some asthma drugs can be taken together. There are some inhalers that contain a combination of two different medications. These devices allow both medications to be delivered from one device, shortening treatment times and decreasing the number of inhalers needed to treat asthma symptoms.

Theophylline for Asthma

Theophylline is another type of bronchodilator that is used to control symptoms of asthma, but it is not delivered in an asthma inhaler. Theophylline is sold under the brand names Uniphyl, Theo-Dur, Slo-Bid, and Theo-24 and is available as an oral (pill and liquid) or intravenous (through the vein) drug. Theophylline is long-acting and prevents asthma attacks. Theophylline is used to treat difficult-to-control or severe asthma and must be taken daily.
Side effects of theophylline include:
  • Nausea and/or vomiting
  • Diarrhea
  • Stomachache
  • Headache
  • Rapid or irregular heartbeat
  • Muscle cramps
  • Jittery or nervous feeling
  • Hyperactivity
These side effects of theophylline may also be a sign of having taken too much medication. Your doctor will check your blood levels of the drug to make sure you are receiving the proper amount.
Always tell your doctors if you take theophylline for asthma because certain medications, such as antibiotics containing erythromycin, seizure medicine, and ulcer medicine can interfere with the way theophylline works. Also, make sure your doctor knows about any other medical conditions you may have, since some diseases and illnesses can change how your body responds to theophylline.
And keep in mind that not only is smoking and exposure to cigarette smoke especially dangerous for those with asthma, but smoking can also interfere with how your body responds to theophylline. Therefore, it is best to avoid smoke when possible.
