Significantly elevated respiratory viral activity, including early increases in influenza viral infections, has contributed to a shortage of commonly used medications, including oseltamivir (Tamiflu ®). Many communities in Washington state may continue to experience shortages in the coming weeks.
To ensure an adequate supply of antiviral medications for individuals who are at high risk for severe influenza-associated complications, the Washington State Department of Health is providing the following recommendations on the use of oseltamivir when supply is limited. Preventative strategies to reduce the burden of influenza should be maintained, including influenza vaccination and messaging about general infection prevention.
*Given the increased circulation of numerous respiratory viruses in the community, we recommend testing to confirm the diagnosis of influenza as long as testing does not delay treatment for priority groups per CDC influenza antiviral medication guidance.
**Oral capsules come in 30, 45 and 75mg strengths. Attention should be paid to ensure appropriate weight-based dosing.
These recommendations are intended to provide guidance, but do not replace clinical judgement, expert consultation or other recognized guidelines (e.g. IDSA, AAP and CDC).
