Antiviral drugs are an important adjunct to influenza vaccination and can be used for treatment of patients with influenza within 2 days of the onset of illness and for chemoprophylaxis of influenza exposures that occur before or less than 2 weeks after vaccination. Patients who are immunocompromised or immunosuppressed, have pulmonary disease, are elderly or are healthcare workers may also be appropriate candidates for chemoprophylaxis.

Antiviral drugs can be used to control institutional influenza outbreaks and for prophylaxis of influenza exposures that occur before or less than 2 weeks after vaccination with inactivated vaccine, or in years when circulating strains differ from those included in the vaccine. They can also be used for early treatment of patients with influenza.
In Brief: Plan B OTC
The Medical Letter on Drugs and Therapeutics • September 11, 2006; (Issue 1243)

The FDA has approved over-the-counter (OTC) sales of Plan B (Duramed), an emergency contraceptive package that contains two 0.75-mg tablets of levonorgestrel, to women ≥18 years old. Younger women still require a prescription. In one trial, two levonorgestrel 0.75-mg tablets taken 12 hours apart, the first within 72 hours after unprotected intercourse, decreased the pregnancy rate to 1%, compared to an expected rate of 8% (Task Force on Postovulatory Methods of Fertility Regulation, Lancet 1998; 352:428). How high doses of a progestin taken after coitus prevent pregnancy is unclear; they may interfere with ovulation, fertilization or implantation.
Nausea and vomiting can occur. The drug will not terminate an established pregnancy. No fetal malformations have been reported after unsuccessful use.
Plan B will not be available OTC until the end of the year, according to the manufacturer, and the OTC price is not yet available. The retail price for the prescription product varies from about $25 to $40. In order to enforce the age restriction, the drug will be kept behind the pharmacist’s counter, and a valid photo ID will be required.

Update: Influenza Resistance to Amantadine and Rimantadine

Our article on Antiviral Drugs for Prophylaxis and Treatment of Influenza (Med Lett Drugs Ther 2005;47:93) mentioned possible use of amantadine (Symmetrel, and others) and rimantadine (Flumadine, and others), but warned that the incidence of resistance has increased substantially. The CDC recently issued a Health Alert (www.cdc.gov) saying that current evidence indicates that a high proportion of circulating influenza A viruses in the US are now resistant to amantadine and rimantadine and they should not be used for this indication, at least this year.

The first commercially available virucidal tissue, KLEENEX Anti-Viral Tissue (Kimberly-Clark), was recently introduced and is being heavily promoted to the general public. Patients may ask healthcare providers about the usefulness of these products. Theoretically, virucidal tissues could interrupt transmission of viral infections by blocking hand contamination and/or small particle aerosols from nose-blowing, sneezing and coughing.

Due to the unanticipated shortage in the US supply of inactivated influenza vaccine, many persons who normally would have received the vaccine will be unable to get it this year. Antiviral drugs can be used for prophylaxis of unvaccinated persons who are exposed to influenza, and for treatment of both vaccinated and unvaccinated patients who develop symptoms of the disease.
