Difference Between Acetaminophen and Ibuprofen

Michelle A. Fritsch, Pharm.D., CGP, BCACP

August 11, 2015

Question

It can often take two or three days for a patient to equilibrate and get used to a dose change.  

Answer

Ibuprofen is a nonsteroidal anti-inflammatory drug and its mechanism of action is a peripherally acting medication that not only reduces pain and fever, but it can also reduce inflammation.  Acetaminophen is a centrally acting medication and it just helps with pain and fever.  They have different mechanisms and they can be used somewhat together.  For instance, if you have a patient with either pain or fever that is not controlled by one, for a short time, we would encourage them to alternate them every three hours.  Individually, they are typically dosed every six hours.  If I took ibuprofen at a certain time and I was not controlled in another three hours, I could take acetaminophen, and then another three hours later, resume the ibuprofen and so on.  I would not take them at the same time, but they can help bridge between medications during acute events like a high fever or pain.

The GLP-1 medications have become a popular treatment for individuals with type II diabetes or obesity. Healthcare providers must understand these medications, including the benefits, adverse effects, and contraindications. For some individuals, these medications can have consequences such as loss of lean mass loss, which can affect their function, health, and longevity. This presentation will provide an evidence-based update on this topic.

Seventy-three percent of older adults have two chronic conditions, and 36% have four or more, leading to management with polypharmacy. One in 5 older adults uses 5 or more prescription medications and is taking a medication that adversely affects a co-existing condition. Polypharmacy bidirectionally impacts physical function and, therefore, physical activity. Adults who participate in aerobic and strengthening activity recommendations have a greatly reduced risk for all-cause mortality. Physical therapists who understand how the movement system interacts with multimorbidity and polypharmacy are uniquely qualified to guide complex patients through safe and effective exercise programs to improve physical function and reduce mortality. This session will use the ACSM exercise recommendation guidelines to consider each multimorbidity’s effect on the exercise prescription, balance polypharmacy considerations, and maximize patient safety and exercise dosing for meaningful results. Using exemplar cases, the learner will be challenged to recognize patterns of multimorbidity and pharmacotherapy, discuss the role of the physical therapist within the multidisciplinary team and in patient communication, and optimize patient outcomes. The Beers List of potentially inappropriate medications to be avoided in older adults will be incorporated, and a schema will be provided to integrate advanced clinical reasoning into the care of complex patients.
