With age comes more chronic health conditions.
Also, some people may develop deficiencies in certain vitamins as they age.
Thankfully, an array of prescription and over-the-counter medications, as well as dietary supplements and vitamins, are available to alleviate symptoms, slow the advancement of many age-related chronic health conditions and help people maintain good health.
Over the years though, store shelves have become crowded with hundreds of herbal supplements and other nutritional enhancers that make various claims about supporting physical and mental health and function.
The word used by many to describe taking multiple prescription and over-the-counter medications, as well as dietary and herbal supplements, is “polypharmacy”.
Although it has many definitions, the broadest definition of polypharmacy is the simultaneous use of multiple medications or supplements to treat one or more medical conditions in one patient.
With more medical conditions as one ages, comes more healthcare providers to treat them.
Unless patients ensure every doctor they see has an up-to-date medication and supplement list, doctors may not accurately know what patients take or communicate about risks related to those medications and supplements.
As people take more and more medications and supplements, the chances for interactions increase.
For example, consider a patient who was prescribed a statin to lower cholesterol.
After seeing an advertisement that promoted red yeast rice as being good for managing cholesterol, she began taking it.
Red yeast rice contains lovastatin, a naturally-occurring statin.
Without realising it, this patient was duplicating her statin therapy.
She began experiencing leg cramping, muscle soreness and elevated liver function tests from this drug interaction.
While it is important to talk with your doctor and pharmacist about what you take to avoid too much medication, it is also important to avoid a deficit.
Consider vegetarian or vegan patients who are newly diagnosed with type 2 diabetes.
Often, these people take a vitamin B12 supplement because they do not eat meat.
However, standard therapy for a type 2 diabetic is a medication known as metformin, which can deplete vitamin B12 in some patients.
So now, having started the metformin, these people require more vitamin B12 supplementation than before.
To complicate matters, if they were already taking, or are starting to take, an anti-reflux, anti-ulcer medication such as omeprazole, which lowers stomach acid production, their vitamin B12 deficiency can further worsen as this vitamin depends on stomach acid for absorption.
There are other examples of supplement or prescription interactions.
For instance, taking calcium with a vitamin D supplement for osteoporosis, and a multivitamin containing vitamin D, may raise calcium in the urine enough to increase the risk of forming kidney stones.
Taking a narcotic pain reliever for acute or chronic pain when already taking an anti-anxiety medication like alprazolam can result in a loss of consciousness.
Even worse would be if people drink an alcoholic beverage while having both alprazolam and a narcotic in their system.
Herbal supplements can pose a risk in polypharmacy patients because they may affect the metabolism of a medication or other supplements.
Resveratrol, which is found in grape skins, is often taken as an antioxidant supplement.
Some evidence suggests that it can slow the metabolism of certain common medications and cause side effects.
Gingko biloba, which is used for memory, can have an anti-platelet effect, increasing the risk of severe bleeding in those patients already taking anticoagulants such as warfarin or apixaban.
When taking multiple prescription medications or over-the-counter drugs and supplements, review them at least annually.
Seeking out a speciality pharmacy or a polypharmacy pharmacist is ideal, as the pharmacist can identify possible drug interactions or adverse drug reactions caused by the various components and can partner with your healthcare providers to avoid future issues.
Also, speak to the pharmacist any time you are prescribed a new medication, so that you can review current prescriptions and supplements to identify any potential concerns. – Mayo Clinic News Network/Tribune News Service
