Watch Out for These 11 Medications That Can Raise Your Blood Sugar

Patients who have diabetes must closely monitor their blood sugar levels. Any sudden changes are a cause for concern. As a result, it’s important for people with diabetes to consult with their physicians when taking medications. Even common over-the-counter medicines may cause spikes in blood sugar, and those spikes can cause problems with diabetes medications as well. Take a look at these 11 medications that may affect your blood sugar. Awareness can help you remember to be attentive when turning to these substances for certain ailments.

11. Pseudoephedrine

Pseudoephedrine is a decongestant and an active ingredient in many cold and flu medications. It has the potential to raise blood glucose and blood pressure, so be sure to check your levels often when taking these types of drugs. They may be over-the-counter, but that doesn’t mean they can’t be dangerous. It’s probably worth talking to your doctor about the advisability of taking these medications when you have the opportunity. Or, instead of pseudoephedrine, try an antihistamine.

10. Cough Syrup


Cough syrup may be fine to use, unless your blood sugar numbers are already high. It’s important to know that there’s a difference between regular and sugar-free cough syrups. If you are not taking the sugar-free kind, cough syrup can increase blood glucose. In addition to checking your blood sugar regularly, take into account the added sugar from cough syrup when calculating your daily diet plan, so you keep your numbers within the range your doctor recommends.

9. Caffeine

Any medication or beverage that has caffeine-like (andrenergic) effects may be best to avoid when you’re sick. Caffeine can cause anxiety, jitters, an accelerated heart rate, high blood pressure, and affect your blood glucose levels. Although, some studies say caffeine may help keep blood sugar levels normal prior to one developing diabetes. However, once a person becomes diabetic, limiting your caffeine intake may be beneficial.
