Is Your Medication Still Working for You?

If you manage a chronic condition like hypertension, type 2 diabetes, or weight, and you take medication for it, from blood pressure prescriptions to newer GLP-1 options, here is a question worth asking yourself this fall: is your current dose still doing the job it was doing a year ago?

Bodies change. Weight shifts, kidney and liver function can change with age, other medications get added or dropped, and even stress and sleep patterns affect how well a drug works for you. A dose that controlled your blood pressure or blood sugar last year may not be hitting the same mark today, and it is easy not to notice, especially if you have not had a check-in with your provider in a while.

This is exactly why groups like the American Heart Association have called for regular medication reviews to be a standard part of care, particularly for people managing more than one chronic condition at once. Deprescribing is described as a proactive, patient-centered strategy meant to reduce medication burden, useful not only after a bad reaction but whenever changing health circumstances call for a fresh look at what someone is taking.

The GLP-1 Factor

This is especially true for anyone on a GLP-1 medication for weight or blood sugar management. These medications do more than help with weight. Research has found that GLP-1 medications also produce modest reductions in blood pressure, typically in the range of 2 to 5 points systolic, across people with diabetes, obesity, or elevated cardiovascular risk, and that this effect comes mainly from the weight loss itself, along with some additional effects on blood vessel function.

In some clinical trials, the effect has been even larger. One major trial found that semaglutide led to significant drops in both systolic and diastolic blood pressure alongside substantial weight loss.

What this means in practice: if you started a GLP-1 medication and have lost a meaningful amount of weight since then, your blood pressure or blood sugar levels may have genuinely improved. That can mean your other prescriptions may now be doing more than they need to. This is not something to adjust on your own. It is something to bring to your provider.

Your pharmacist is one of the most underutilized resources in your healthcare team.

Signs It Might Be Time for a Conversation

• Numbers at home, blood pressure or blood sugar, that used to be steady but have started running lower or higher than expected
• A prescription refill that has not changed in over a year without a recent check-in
• Meaningful weight loss since starting a GLP-1 medication, especially alongside other prescriptions for blood pressure or diabetes
• New symptoms, dizziness, or fatigue that could signal blood pressure running too low
• Adding a new medication, even an over-the-counter one, without asking whether it affects an existing prescription

None of this means something is wrong. It means your body keeps changing, and your care should keep pace with it. If it has been a while, back to school season is as good a nudge as any to put a provider visit on your own calendar too.
