|ipratropium and albuterol||Combivent, DuoNeb|
Ipratropium alone and combined with albuterol is available in metered-dose inhalers (MDI) and as a liquid form for use in compressor-driven nebulizers . Inhalers may be used differently, depending on the medicine used. Always read the directions to be sure you are using the inhaler correctly.
How It Works
Anticholinergics relax the airways and prevent them from getting narrower. This makes it easier to breathe. They may protect the airways from spasms that can suddenly cause the airway to become narrower (bronchospasm). They also may reduce the amount of mucus produced by the airways.
Anticholinergics begin to work within 15 minutes, work best after 1 to 2 hours, and usually last from 3 to 4 hours (but may last up to 6 hours in some people).
Why It Is Used
Inhaled anticholinergics are usually used for severe asthma attacks . They are sometimes used in the home, but they are not used as daily maintenance treatment for persistent asthma . And they are sometimes used with another medicine.
Anticholinergics may be used:
- Along with short-acting beta2-agonists to treat severe asthma attacks or status asthmaticus , a long-lasting and severe asthma attack that does not respond to standard treatment.
- As an added medicine used after short-acting beta2-agonists during an asthma attack. The combination may relieve symptoms for a longer period of time.
Medicine treatment for asthma depends on a person's age, his or her type of asthma, and how well the treatment is controlling asthma symptoms.
- Children up to age 4 usually are treated a little differently from those 5 to 11 years old.
- The least amount of medicine that controls the asthma symptoms is used.
- The amount of medicine and number of medicines are increased in steps. So if asthma is not controlled at a low dose of one controller medicine, the dose may be increased. Or another medicine may be added.
- If the asthma has been under control for several months at a certain dose of medicine, the dose may be reduced. This can help find the least amount of medicine that will control the asthma.
- Quick-relief medicine is used to treat asthma attacks. But if you or your child needs to use quick-relief medicine a lot, the amount and number of controller medicines may be changed.
Your doctor will work with you to help find the number and doses of medicines that work best.
How Well It Works
- Improves lung function compared to using a short-acting beta2-agonist alone.
- Reduces hospital admission for adults and children with severe asthma attacks.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
- Usually the benefits of the medicine are more important than any minor side effects.
- Side effects may go away after you take the medicine for a while.
- If side effects still bother you and you wonder if you should keep taking the medicine, call your doctor. He or she may be able to lower your dose or change your medicine. Do not suddenly quit taking your medicine unless your doctor tells you to.
Side effects are rare with inhaled ipratropium but may include:
- Dry mouth.
- Increased wheezing .
- Delay in bringing relief from symptoms (if used without short-acting beta2-agonists).
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
What To Think About
Anticholinergics, such as ipratropium, are sometimes used with albuterol for severe asthma attacks.
Many doctors recommend that every child who uses a metered-dose inhaler (MDI) also use a spacer , which is attached to the MDI. A spacer may deliver the medicine to the lungs better than an inhaler alone. And for many people a spacer is easier to use than an MDI alone.
Try to avoid giving your child an inhaled medicine when he or she is crying, because not as much medicine is delivered to the lungs.
If you have the eye disease glaucoma, talk with an eye doctor before you start taking anticholinergics. People who have glaucoma may need to be watched more closely while they are taking these medicines.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed .
Advice for women
If you are pregnant, breastfeeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breastfeeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
