What is the hepatitis B/hepatitis A vaccine? What is it for?
Hepatitis A/B vaccine is a man-made combination vaccine containing inactivated hepatitis A virus strain and non-infectious hepatitis B virus surface antigen. Inactive Hepatitis A virus combined with hepatitis B antigens stimulates the immune system to develop immunity against hepatitis A and B virus infections. The FDA approved hepatitis A/B vaccine in May 2001.

What are the side effects of hepatitis B/hepatitis A vaccine?
Side effects of hepatitis A/B vaccine are injection site soreness and pain, headache, fatigue, redness, diarrhea, nausea, and fainting. The tip caps of pre-filled syringes may contain latex which can cause allergic reactions in latex-sensitive people. Serious allergic reactions, abnormal heart beats, and hair loss have also been reported.
What is the dosage for hepatitis B/hepatitis A vaccine?
Adults of 18 years of age or older:
- Standard dosing: Standard dosing schedule consists of 3 doses of 1 ml each. Administer 1 ml, intramuscularly on deltoid muscle, at 0, 1, and 6 months.
- Accelerated dosing: Accelerated dosing schedule consists 4 doses of 1 ml each. Administer 1 ml intramuscularly into the deltoid muscle on days 0, 7, and 21 to 30, followed by a 4th dose at month 12.
Safe and effective use of hepatitis A/B vaccine in patients younger than 18 years of age has not been established.
Which drugs or supplements interact with hepatitis B/hepatitis A vaccine?
: Hepatitis A/B vaccine vaccines should not be used with medications and therapies that suppress the immune system such as adalimumab (Humira), belimumab (Benlysta), cyclosporine (Gengraf, Neoral, Sandimmune), azathioprine (Imuran), irradiation, and high doses of steroids because suppressing the immune system reduces the effectiveness of hepatitis A/B vaccine.

How should I keep hepatitis B/hepatitis A vaccine stored?
Store hepatitis A/B vaccine under refrigeration between 2 C and 8 C (36 F and 46 F). Do not freeze hepatitis A/B vaccine vaccines and discard if they have been frozen.
Hepatitis A and hepatitis B (recombinant) vaccine (Twinrix) is a vaccine prescribed to immunize adults 18 years old of age or older against hepatitis A and all types of hepatitis B infections.

Sexually Transmitted Diseases in Women (STDs)
Sexually transmitted diseases (STDs) are among the most common infectious diseases in the United States. STDs can be spread through any type of sexual activity involving the sex organs, the anus or mouth, or through contact with blood during sexual activity. Examples of STDs include, chancroid, chlamydia, gonorrhea, granuloma inguinale, lymphogranuloma venereum, syphilis, genital herpes, genital warts, trichomoniasis, pubic lice (crabs), and scabies. Treatment is generally with antibiotics; however, some STDs that go untreated can lead to death.
Hepatitis (Viral Hepatitis A, B, C, D, E, G)
Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, E, F (not confirmed), and G) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease). The main nonviral causes of hepatitis are alcohol and drugs. Many patients infected with hepatitis A, B, and C have few or no symptoms of illness. For those who do develop symptoms of viral hepatitis, the most common are flu-like symptoms including: loss of appetite, nausea, vomiting, fever, weakness, tiredness, and aching in the abdomen. Treatment of viral hepatitis is dependent on the type of hepatitis.
Bile Duct Cancer (Cholangiocarcinoma)
Bile duct cancer (cholangiocarcinoma) is a rare type of cancer that arises from cells that line the drainage system from the liver and gallbladder to the intestine. Symptoms of bile duct cancer include jaundice, itching, weight loss, and abdominal pain. Physical examination, specialized blood tests, and imaging tests may be used to diagnose bile duct cancer. Treatment for bile duct cancer may include chemotherapy, radiation therapy, and photodynamic therapy. Bile duct cancer typically has a poor prognosis. Preventing liver damage may decrease the risk of developing bile duct cancer.
Burns (First Aid)
Burn types are based on their severity: first-degree burns, second-degree burns, and third-degree burns. First-degree burns are similar to a painful sunburn. The damage is more severe with second-degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third-degree burns. Burn treatment depends upon the burn location, total burn area, and intensity of the burn.
Hepatitis C (HCV, Hep C)
Hepatitis C is an inflammation of the liver due to the hepatitis C virus (HCV), which is usually spread by blood transfusion, hemodialysis, and needle sticks, especially with intravenous drug abuse. Symptoms of chronic hepatitis include fatigue, fever, muscle aches, loss of appetite, and fever. Chronic hepatitis C may be cured in most individuals with drugs that target specific genomes of hepatitis C.
Hepatitis A (HAV, Hep A)
Hepatitis means inflammation of the liver. Hepatitis A (HAV, Hep A) is one type of liver disease caused by a virus. Since hepatitis A is a virus, it can pass from person to person from eating or drinking contaminated food or coming into contact with contaminated materials containing the virus. Symptoms of hepatitis A include stomach pain, diarrhea, dark yellow urine, jaundice, and more. There is a vaccine to prevent contracting hepatitis A.
Hepatitis B (HBV, Hep B)
The hepatitis B virus (HBV, hep B) is a unique, coated DNA virus belonging to the Hepadnaviridae family of viruses. The course of the virus is determined primarily by the age at which the infection is acquired and the interaction between the virus and the body's immune system. Successful treatment is associated with a reduction in liver injury and fibrosis (scarring), a decreased likelihood of developing cirrhosis and its complications, including liver cancer, and a prolonged survival.
Sexual Problems (Sex) in Women
Sexual dysfunction refers to a problem that arises during any phase of the sexual response cycle, preventing an individual or couple from experiencing sexual satisfaction. Physical, medical, and psychological conditions may affect sexual functioning, resulting in inhibited sexual desire, inability to become aroused, lack of orgasm, and painful intercourse. Treating the underlying physical and psychological problems usually resolves most female sexual problems.
Hepatitis A and B Vaccinations
Hepatitis A and hepatitis B are the two most commnon viruses that infect the liver. Hepatitis A and Hepatitis B can be prevented and treated with immunizations (vaccinations) such as Havrix, Vaqta, Twinrix, Comvax, Pediarix, and hepatitis b immune globulin (HBIG).
Is Hepatitis B Contagious?
Hepatitis B is a type of liver infection. Hepatitis B is spread through person-to-person contact or through personal items like razors, toothbrushes, etc. Symptoms of hepatitis B include fever, yellowish skin (jaundice), dark urine, fatigue, nausea, and vomiting. There is no drug to cure hepatitis B; however, there is a hepatitis B vaccine available.
Is Hepatitis A Contagious?
Hepatitis means inflammation of the liver. Hepatitis A is one type of hepatitis. Hepatitis is transmitted through person to person contact, contaminated ice, vegetables, fruits, and untreated water. Hepatitis A can be prevented by the hepatitis A vaccine. Symptoms of hepatitis A may include nausea and/or vomiting, fever, loss of appetite, abdominal pain, dark urine, clay-colored stools, jaundice (yellowish color to skin and/or eyes, or joint pain.
Sexually Transmitted Diseases and Pregnancy (STDs)
When you are pregnant, many sexually transmitted diseases (STDs) can be especially harmful to you and your baby. These STDs include herpes, HIV/AIDS, genital warts (HPV), hepatitis B, chlamydia, syphilis, gonorrhea, and trichomoniasis. Symptoms include bumps, sores, warts, swelling, itching, or redness in the genital region. Treatment of STDs while pregnant depends on how far along you are in the pregnancy and the progression of the infection.
Liver Cancer (Hepatocellular Cancer) Prevention
Avoiding certain risk factors (such as hepatitis B and C, cirrhosis, and aflatoxin) can lower one's risk of developing liver cancer. Getting the hepatitis B vaccine is a protective factor against liver cancer.
