Medications and Older Adults

Medications and Older AdultsAs people age, the number of medications they take often increases significantly. It is essential that older patients have an awareness of what medications they are taking, how to take them and what the potential side effects can be. This is especially true for older adults with allergies or asthma.

It is important not to let your treatments become asthma triggers. The best way to avoid medication-induced asthma is to talk with your physician about what medications are best for you.

Asthma Medications
There are times when a medication can be very beneficial for one ailment, but has the potential to cause concern for another condition. Such is the case with a particular class of asthma medications: inhaled corticosteroids (ICS). On the one hand, corticosteroids are known to contribute to the development of osteoporosis (a condition leading to brittle bones), which is a common problem for older patients, especially women. On the other hand, ICS is the most effective class of drugs in the treatment of asthma. There is concern that ICS may lead to osteoporosis because oral and injected steroids are well-known to contribute to this process.

Apart from being a potentially life-threatening disease, uncontrolled asthma puts you at a high risk for other complications. If your asthma is uncontrolled, you may not be sleeping well, it could become difficult to maintain an active lifestyle and you may require hospitalization. Reduced levels of activity, in turn, can also cause osteoporosis.

An allergist / immunologist, often referred to as an allergist, has extensive training in the management of asthma and in minimizing the side effects of medications such as inhaled corticosteroids.

Allergy Medications
Allergies such as allergic rhinitis (hay fever), allergic conjunctivitis (eye allergy) and urticaria (hives) are common problems for older adults and often require the use of antihistamines. Antihistamines are divided into two classes: first generation antihistamines and second generation antihistamines.
First generation antihistamines, while very effective at controlling symptoms, are often associated with symptoms in older adults such as anxiety, confusion, sedation, blurred vision, reduced mental alertness, urinary retention and constipation. These side effects are even more common if you are being treated with certain antidepressant medications.

The second and third generation antihistamines do not cross the blood-brain barrier as readily and, therefore, cause fewer side effects. If you have allergies that require an antihistamine, discuss with your physician the use of second generation antihistamines in place of a first generation antihistamine. Physician and allergist prescribed antihistamines currently in use are generally second or third generation drugs that have an extremely favorable safety profile for users.

Drugs That Can Trigger Asthma
These drugs are often used for problems such as high blood pressure, heart disease and migraine headache. They may also be used in an eye drop form for treating the eye disease glaucoma. They are classified in one of two groups: non-specific and specific.

Non-specific beta-blockers, such as propanalol, are the most important ones to avoid. Ideally, a person with asthma would avoid all beta-blockers, but these types of drugs may be quite important for certain patients' health and may not substantially worsen their asthma. Your physician may conduct a trial using a "specific" beta-blocker. Remember that even beta-blockers in eye drops may make asthma worse, so be sure to tell your ophthalmologist that you have asthma.

Aspirin and Other Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
This group of medications include some common over-the-counter pain relievers, such as ibuprofen and naproxen. Approximately 10 to 20% of people with asthma may notice that one or more of these drugs trigger their asthma. These asthma attacks may be severe and even fatal, so patients with known aspirin sensitivity must be very careful to avoid these drugs. Medications that usually don't cause increased asthma in aspirin-sensitive patients include acetaminophen (low to moderate dose), propoxyphene and prescribed narcotics such as codeine.

ACE Inhibitors
These drugs, which may be used for hypertension or heart disease, include lisinopril and enalapril. Although they usually don't cause asthma, approximately 10% of patients who receive one of these drugs develop a cough. This cough may be confused with asthma in some patients and possibly trigger increased wheezing in others. In addition, any cough can be associated with reflux (acid coming up from the stomach into the esophagus) which can cause more coughing and worsen asthma.

Healthy Tips
• Older patients should always know what medications they are taking, how they to take them and what the potential side effects can be. Work regularly with your allergist to fine tune your medications and control your asthma-related side effects.
• Inhaled corticosteroids (ICS) are the most effective class of drugs in the treatment of asthma, but are known to contribute to the development of osteoporosis.
• If you have allergies that require an antihistamine, discuss with your physician the use of second generation antihistamines in place of a first generation antihistamine.
• Some drugs, such as beta-blockers and non-steroidal anti-inflammatory drugs (NSAIDs), may trigger asthma in some people.
