Guideline/Drug Updates: 2020 RxPrep Course Book
NAPLEX-relevant updates from June 2019-May 2020

PageUpdate TypeDescription
Chapter 20: Immunizations
p. 322-328Guideline Update November 2019

Prevnar 13 is no longer routinely recommended in those ≥ 65 years of age. It can be administered based on shared clinical decision making between the patient and healthcare provider. A single dose of Prevnar 13 is still recommended for immunocompromised patients ≥ 6 years old if not previously received (see Study Tip Gal p. 328).

The update above applies to the following content:

  • p. 322: Vaccinations for Special Groups, Older Adults: first bullet under Pneumococcal vaccines (age ≥ 65 years).
  • p. 323: Vaccinations for Adults, Pneumococcal: first bullet under Prevnar 13 (if not received before).
  • p. 327: Pneumococcal Vaccines: third bullet.

Guidelines for the Treatment of Community-acquired Pneumonia

p. 384Guideline Update February 2020

The Centers for Disease Control and Prevention and the National Tuberculosis Controllers Association have published updated guidelines for the Treatment of Latent Tuberculosis Infection.

Regimens with shorter durations (e.g., 3 or 4 months) are preferred due to higher completion rates and less risk of hepatotoxicity when compared to longer courses of isoniazid (INH).

Preferred Regimens

  • INH + rifapentine weekly for 12 weeks
    • Recommended for adults, children > 2 years old and HIV-positive patients (if no drug interactions with antiretroviral therapy)
    • Do not use in pregnant women (see Alternative Regimens)
  • Rifampin daily for 4 months
    • Recommended for HIV-negative adults and children of any age
    • Watch for drug interactions with rifampin (a CYP inducer)
  • INH + rifampin daily for 3 months
    • Recommended for adults, children of any age and HIV-positive patients (if no drug interactions with antiretroviral therapy)

Alternative Regimens

  • INH daily for 6 months or 9 months
    • An option for all adults (HIV-negative and HIV-positive) and children of any age
    • The regimen of choice for pregnant women
    • May be preferred in HIV-positive patients who cannot take a preferred regimen due to drug interactions with antiretroviral therapy

Guidelines for the Treatment of Latent Tuberculosis Infection

Chapter 26: Human Immunodeficiency Virus
p. 418Guideline Update December 2019

Dolutegravir/lamivudine (Dovato) was added to the “Recommended Initial Regimens” as the first approved two-drug regimen. Dovato is only recommended for the following patients:

  • No active hepatitis B
  • Low viral load
  • No known resistance to the components of Dovato

Recommendations for Initial Combination Regimens for the Antiretroviral-Naive Patient

p. 419Guideline Update December 2019

The recommendations for the Use of Antiretroviral Drugs in Pregnant Women with HIV have been updated. Dolutegravir can now be used with 2 NRTIs as a preferred treatment in pregnancy. The true incidence of neural tube defects in the United States from dolutegravir is unknown but is lower than previously reported.

In the section on Regimens for Antiretroviral-Naïve Pregnant Women:

  • Cross out the last sentence in the second paragraph. Dolutegravir should be avoided due to a risk of neural tube defects.
  • Add dolutegravir to the INSTI column of the table.
