Five Medication Combinations Older Adults Should Avoid As They Age
As people get older, their bodies may take longer to remove medicines.
This means medicines can stay in the body for too long.
Taking some medicines together can create serious problems.
Blood thinners and certain painkillers can increase bleeding.
Some blood-pressure medicines and potassium products can raise potassium to dangerous levels.
Sleeping pills and opioid pain medicines can make breathing dangerously slow.
Calcium products can stop thyroid medicine from working properly.
Some antibiotics and antifungals can make statins harm muscles and kidneys.
Older adults should ask a doctor or pharmacist to review every medicine and supplement they take.
Age-related declines in liver and kidney function can slow medication processing and increase toxicity risks.
Blood thinners combined with NSAIDs such as ibuprofen or naproxen may cause gastrointestinal bleeding and ulcers.
ACE inhibitors combined with potassium supplements or potassium-sparing drugs may cause dangerously high potassium levels.
Sedatives or sleeping pills taken with opioids can lead to severe sedation, falls, confusion, and breathing problems.
Calcium or antacid products, and certain antifungals or antibiotics, can interfere with thyroid medicines or statins, respectively.
