Uncomplicated UTI (uUTI) Updates

• UTI in Males

TL;DR:

1 IDSA has updated the definition for uUTI. The same antibiotics and duration should be used in men and in women.

2 Nitrofurantoin is the preferred agent for uUTI.  Alternatively, consider prescribing cephalexin 500 mg BID instead of QID.

GLP-1 agonists and the side effects you might see

• Quick Facts for SLP.1s

TL;DR:

1 Understanding the common side effects of GLP-1 agonists and their risk factors is necessary as the number of patients taking them increase.

2 The most common side effects are the GI side effects, many of which will dissipate after the first couple of months of treatment or by decreasing the dose.

3 Half-lives vary from hours to over a week for the different agents and formulations.

• Is Diphenhydramine needed for all patients who receive metoclopramide or prochlorperazine?

TL;DR:

1 Prochlorperazine was shown to be more effective for relieving migraine headache than metoclopramide when both are dosed at 10 mg IV

2 Diphenhydramine prevented akathisia when metoclopramide 20 mg IV or prochlorperazine 10 mg IV was administered for acute migraines

3 Diphenhydramine should NOT be given to prevent akathisia with metoclopramide 10 mg IV due to lack of proven clinical efficacy
