TRENDING TOPICS CDC HEALTH ADVISORY ON IVERMECTIN

BEHAVIORAL HEALTH CORNER: OPIOIDS

The CDC has issued an official health advisory on increases in ivermectin prescriptions and reports of severe illness with use for prevention or treatment of COVID-19. Ivermectin is FDA-approved for treating certain parasitic infections and is generally well tolerated when used as indicated. However, during the COVID-19 pandemic there has been a 24-fold increase in the dispensing of prescription ivermectin as well as human use of OTC veterinary ivermectin. Compared to before the pandemic, a five-fold increase in calls to poison control centers related to adverse effects associated with misuse and overdose of these products has been reported. Ivermectin is not FDA-approved or authorized for preventing or treating COVID-19, and the NIH guidelines have found data are insufficient to recommend the product as a COVID-19 treatment.

The FDA has announced a public workshop will be held for reconsideration of mandatory opioid education for prescribers. The upcoming October 2021 workshop will facilitate discussion with stakeholders on components of the opioid crisis that could be improved through requiring prescriber education as part of the Opioid Analgesic REMS. The benefits of a single source for education to address use and risks of opioids and treatment of OUD will also be discussed.

FDA-approved oral formulations are indicated for treating onchocerciasis (river blindness) and intestinal strongyloidiasis; topical formulations are indicated for treating head lice and rosacea. Before the pandemic, the average prescriptions per week being dispensed from retail pharmacies in the US was 3,600; prescriptions rose to 39,000 per week in January 2021 and to > 88,000 prescriptions per week in August 2021. Relatedly, in January 2021, calls to poison control centers for exposure to ivermectin increased to levels three-times greater than before the pandemic, and in July 2021, calls increased to five-times more than pre-pandemic baseline levels. Animal formulations of ivermectin are available for prevention and treatment of parasitic infection in animals; however, people have ingested these products, some of which are intended for use in large animals and contain highly concentrated amounts leading to overdose levels. Additionally, these veterinary formulations can contain inactive ingredients not assessed in humans. Overdose symptoms include GI toxicity, hypotension, and neurologic changes (e.g., confusion, hallucinations, seizures, coma, death) which may be further exacerbated by other CNS depressants (e.g., benzodiazepines and barbiturates). 2 | OCTOBER 2021

COVID-19: NOTABLE DEVELOPMENTS The FDA has amended the EUA for the Pfizer-Biontech COVID-19 vaccine authorizing a single booster dose, ≥ 6 months following completion of the primary 2-dose series, for the following individuals: 1) ≥ 65 years old, 2) 18 to 64 years old at high risk of severe COVID-19, and 3) 18 to 64 years old with institutional/ occupational exposure to SARS-CoV-2 resulting in a high risk of serious complications from COVID-19. This EUA update follows the FDA’s VRBPAC September 17th meeting; the booster was not recommended for all ≥ 16 years old, primarily due to insufficient safety data and the risk of myocarditis in young men. Interim CDC guidance recommends that certain populations should (e.g., ≥ 65 years old) receive a booster of the Pfizer-Biontech vaccine while other populations may (e.g., high risk occupational/institutional settings) receive the booster. The FDA issued a statement on COVID-19 vaccination in children that aligns with a release from the AAP cautioning against off-label use of COVID-19 vaccines in those < 12 years old. For more resources on COVID-19, visit the Magellan Rx Coronavirus Update webpage. For the most current information, visit the FDA, CDC, NIH, NIH guidelines, and WHO websites. State and local health departments also provide valuable information regarding management in local communities. As the COVID-19 landscape is fluid, assumptions are subject to change.


DRUG INFORMATION

HAPPENINGS & HIGHLIGHTS • Pfizer has expanded the voluntary recall of varenicline (Chantix®) 0.5 mg and 1 mg tablets to include all remaining lots due to N-nitroso-varenicline at or above the FDA’s interim acceptable limit. The precautionary recall is to the consumer level and follows the approval of alternative suppliers’ product. Although the health benefits from quitting smoking outweigh the theoretical cancer risk, long-term exposure may be associated with a potential increased risk for cancer. • Jacobus has voluntarily recalled 3 lots of amifampridine (Ruzurgi®) 10 mg tablets to the consumer level due to contamination with yeast, mold, and aerobic bacteria. Drug product with substantial contamination has the potential to lead to serious and life-threatening infections. • Azurity has issued a voluntary recall of 1 lot of vancomycin HCl for oral solution (Firvanq®) 50 mg/mL kit to the consumer level, as some products contain the incorrect diluent (incorrectly contain a First® Omeprazole [FIRST®-PPI] diluent). This may result in incomplete solubilization impacting the overall dose administered, potentially leading to persistent infection.

• The FDA is requiring revisions to the Boxed Warning of the labels for tofacitinib (Xeljanz®/Xeljanz XR®), baricitinib (Olumiant®), and upadacitinib (Rinvoq™) to include information about increased risks for serious CV events, cancer, blood clots, and death. While this change is based on data from a large, randomized, safety clinical trial of tofacitinib in RA patients, baricitinib and upadacitinib are included in the action based on their shared mechanism of action with tofacitinib. This update by the FDA does not apply to other JAK inhibitors, ruxolitinib (Jakafi®) and fedratinib (Inrebic®), which are used in the oncology setting. The agency is also limiting all approved uses of tofacitinib, baricitinib, and upadacitinib to certain patients who have not responded or cannot tolerate ≥ 1 TNF blocker. • The FDA has granted full approval of pembrolizumab (Keytruda®) in patients with locally advanced or metastatic urothelial carcinoma (UC) who are not eligible for any platinum-containing chemotherapy (regardless of PD-L1 status); previously this indication was an Accelerated Approval. Dosage for UC is 200 mg every 3 weeks or 400 mg every 6 weeks via IV infusion.

DRUG INFORMATION HAPPENINGS • The CDC has published ACIP’s recommendations on prevention and control of seasonal influenza with vaccines in the US for the upcoming influenza season; the AAP has also released recommendations for influenza prevention. • ICER has published the final evidence report and policy recommendations for atopic dermatitis therapies. • The ADA convened an international expert group and has published a consensus report on defining and interpreting remission in T2DM. • The NAMS has published a 2021 position statement on managing osteoporosis in postmenopausal women. • The USPSTF has issued a final recommendation statement on screening for prediabetes and T2DM. In asymptomatic adults 35 to 70 years old who are overweight or obese, it is recommended to screen for these conditions, and HCPs should offer/refer those with prediabetes to receive interventions for preventing progression to diabetes (Grade B).
