Amantadine Hydrochloride and BayRho-D

• Generic Name: amantadine
• Dosage Forms: n.a.
• Other Brand Names: Gocovri, Osmolex ER, Symmetrel

Has been used for treatment of uncomplicated respiratory tract illness caused by susceptible influenza A virus in adults, adolescents, and children ≥1 year of age.

Amantadine and rimantadine have little or no activity against influenza B; not used for treatment of influenza B infection.

Beginning in the 2005–2006 influenza season, most strains of influenza A (H3N2) circulating in the US were resistant to adamantanes (amantadine, rimantadine), and resistance to these drugs among seasonal influenza A (H3N2) isolates has remained high during subsequent influenza seasons. In addition, the influenza A (H1N1)pdm09 virus circulating during recent influenza seasons is resistant to amantadine and rimantadine.

CDC and other experts recommend that adamantanes (amantadine, rimantadine) not be used for treatment of seasonal influenza in the US until susceptibility to these antiviral agents has been reestablished in circulating influenza A viruses.

Consider viral surveillance data available from local and state health departments and the CDC when selecting an antiviral for treatment of seasonal influenza. Strains of circulating influenza viruses and the antiviral susceptibility of these strains constantly evolve.

CDC issues recommendations concerning use of antivirals for treatment of influenza, and these recommendations are updated as needed during each influenza season. Information regarding influenza surveillance and updated recommendations for treatment of seasonal influenza are available from CDC.

Prevention of Seasonal Influenza A Virus Infections

Has been used for prophylaxis of signs and symptoms of influenza infection caused by susceptible influenza A in adults, adolescents, and children ≥1 year of age.

Amantadine and rimantadine have little or no activity against influenza B; not used for prevention of influenza B infection.

Annual vaccination with seasonal influenza virus vaccine, as recommended by the US Public Health Service Advisory Committee on Immunization Practices (ACIP), is the primary means of preventing seasonal influenza and its severe complications. Prophylaxis with an appropriate antiviral active against circulating influenza strains is considered an adjunct to vaccination for control and prevention of influenza in certain individuals.

CDC and other experts recommend that adamantanes (amantadine, rimantadine) not be used for prevention of influenza in the US until susceptibility to these antiviral agents has been reestablished in circulating influenza A viruses.

Consider viral surveillance data available from local and state health departments and the CDC when selecting an antiviral for prophylaxis of influenza. The most appropriate antiviral for prevention of influenza is selected based on information regarding the likelihood that the influenza strain is susceptible and the known adverse effects of the drug. Strains of circulating influenza viruses and the antiviral susceptibility of these strains constantly evolve.

CDC issues recommendations concerning use of antivirals for prophylaxis of influenza, and these recommendations are updated as needed during each influenza season. Information regarding influenza surveillance and updated recommendations for prevention of seasonal influenza are available from CDC.

Avian Influenza A Virus Infections

Has been recommended as alternative for treatment or prophylaxis of avian influenza A virus infections in certain situations.

CDC and WHO recommend use of a neuraminidase inhibitor (oseltamivir, zanamivir) for treatment or prophylaxis of avian influenza A infections.

If neuraminidase inhibitors unavailable, use of amantadine or rimantadine might be considered an alternative if local surveillance data indicate the strain is known or likely to be susceptible. Avian influenza A (H5N1) and avian influenza A (H7N9) generally have been resistant to adamantanes.

Parkinsonian Syndrome and Drug-induced Extrapyramidal Effects

Symptomatic treatment of parkinsonian syndrome including postencephalitic, idiopathic, arteriosclerotic types and for the relief of parkinsonian signs and symptoms of carbon monoxide poisoning. Less effective than levodopa.

Symptomatic treatment of antipsychotic-induced extrapyramidal effects.

• Generic Name: rho (d) immune globulin
• Dosage Forms: n.a.
• Other Brand Names: HyperRHO S/D Full Dose, HyperRHO S/D Mini Dose, MicRhoGAM, MicRhoGAM Ultra-Filtered Plus, RhoGAM, RhoGAM Ultra-Filtered Plus, Rhophylac, WinRho SDF, Gamulin Rh, Mini-Gamulin Rh, HypRho-D Mini-Dose, BayRho-D, BayRHo-D Full Dose, BayRHo-D Mini-Dose, Anti-D Immunoglobulin, D-Gam Anti-D, Partobulin SDF, Liberim D

Rho(D) immune globulin is used to treat immune thrombocytopenic purpura (ITP) in patients with Rh-positive blood. ITP is a type of blood disorder where the person has a very low number of platelets. Platelets help to clot the blood. Rho(D) immune globulin is also used to prevent antibodies from forming after a person with Rh-negative blood receives a transfusion with Rh-positive blood, or during pregnancy when a mother has Rh-negative blood and the baby is Rh-positive. It belongs to a group of medicines called immunizing agents. Rho(D) immune globulin works to boost the immune system and prevent excessive bleeding.

The Rh factor is one part of the red blood cell. A person has either Rh-positive or Rh-negative blood. If you receive the opposite type of blood, your body will create antibodies that can destroy the red blood cells. When a pregnant woman is Rh-negative and her baby is Rh-positive, the baby's blood can get into her system and cause her to make antibodies. When the same woman has a second baby with Rh-positive blood, the antibodies will destroy the red blood cells in the baby. Rho(D) immune globulin is given to these women during pregnancy or after delivery to prevent them from making antibodies.

This medicine is to be administered only by or under the supervision of your doctor.
