Antiviral Drug Supply - Notice From CDC

Some manufacturers are reporting delays in filling orders and CDC is aware of spot shortages of antiviral drugs, specifically generic versions of oseltamivir capsules and suspension in some places experiencing high influenza activity. What should we do?

  • When commercially-manufactured liquid suspension formulation is not readily available, pharmacists may compound an oral suspension from oseltamivir 75mg capsules as described in the FDA-approved manufacturer package inserts as an alternative.
  • Pharmacies and others attempting to make bulk purchases of influenza antiviral drugs may need to call more than one distributor or manufacturer to locate medications available for purchase in the short term.
  • Individual patients seeking to fill an influenza antiviral prescription may want to call ahead to make sure their pharmacy has product on the shelf to fill their prescription. It may be necessary to call more than one pharmacy to locate these medications.
  • Additional discounts may be available through some pharmaceutical providers.
