Jamp Atazanavir: Uses, Side Effects and Dosage

What is JAMP Atazanavir used for?

JAMP Atazanavir is used in combination with other antiviral drugs to treat human immunodeficiency virus (HIV) infection in adults and pediatric patients 6 years of age and older and weighing at least 20 kg. HIV is the virus that causes Acquired Immune Deficiency Syndrome (AIDS).

How does JAMP Atazanavir work?

HIV destroys CD4+ (T) cells. These cells are important to help the immune system fight infection. After a large number of T cells are destroyed, AIDS develops. JAMP Atazanavir belongs to a family of medicines called protease inhibitors. These help control HIV infection by blocking HIV protease, an enzyme that HIV needs to multiply. This lowers the amount of HIV in your blood (called “viral load”) and allows the number of T cells in your body to increase.

JAMP Atazanavir does not cure HIV infection or AIDS. You may continue to develop infections or other conditions associated with HIV infection. Because of this, it is very important for you to remain under the care of a healthcare professional while taking JAMP Atazanavir.

Do not use JAMP Atazanavir if:

• you are taking any medication listed in this leaflet in the Serious Drug Interactions box below.
• you are allergic to atazanavir sulfate or any of the other ingredients in JAMP Atazanavir.
• you have or have had severe liver disease.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take JAMP Atazanavir. Talk about any health conditions or problems you may have, including if you:

• have liver problems, including Hepatitis B or C infection because the dose of JAMP Atazanavir may need to be reduced.
• have kidney problems.
• have or have had heart problems including a slow heartbeat or a genetic condition called “long congenital QT syndrome”.
• have problems with your electrolytes (low levels of potassium, magnesium or calcium in your blood) or suffer from excessive vomiting or diarrhea.
• have hemophilia Type A or B.
• have lactic acidosis (high levels of acid in the blood). See the Serious side effects and what to do about them table below for symptoms. Talk to your healthcare professional right away if you get these symptoms.
• are taking quetiapine (SEROQUEL*, SEROQUEL* XR), a medicine used to treat mental health problems such as schizophrenia. Serious side effects that could result in death have happened in patients taking quetiapine together with HIV protease inhibitors.

• are lactose intolerant or have one of the following rare hereditary diseases:

  • Galactose intolerance,
  • Lapp lactase deficiency, or
  • Glucose-galactose malabsorption,

because lactose is a non-medicinal ingredient in JAMP Atazanavir.

Other warnings you should know about:

JAMP Atazanavir can cause serious side effects:

• Gallbladder problems: Gallstones and gallbladder inflammation have been reported.
• Heart problems: JAMP Atazanavir can cause changes in the way your heart beats (heart rhythm changes).

• Immune reconstitution inflammatory syndrome: Changes to your immune system can happen when you start taking HIV medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Autoimmune disorders can also happen. This is when the immune system attacks healthy body tissue. Examples of this include Grave's disease (which affects the thyroid gland), Guillain-Barré syndrome (which affects the nervous system) or polymyositis (which affects the muscles). Autoimmune disorders may occur many months after the
• Kidney stones: There have been reports of kidney stones.
• Serious skin reactions: Serious skin reactions including Stevens-Johnson syndrome (SJS), erythema multiforme and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in patients receiving JAMP Atazanavir.

See the Serious side effects and what to do about them table below for more information on these and other serious side effects.

Diabetes and high blood sugar: There have been reports of increased blood sugar and development or worsening of diabetes in patients using protease inhibitors like JAMP Atazanavir. Tell your healthcare professional if you have diabetes or a history of high blood sugar. If you take insulin or oral medicines to control your blood sugar your dose might need to be changed.

Fat redistribution: Changes in body fat have been seen in some patients taking antiretroviral medicines. These changes may include increased amount of fat in the upper back and neck (buffalo hump), the breasts and around the trunk. Loss of fat from the legs, arms and face may also happen.

Pregnancy and breastfeeding:

• Tell your healthcare professional if you are pregnant, think you might be pregnant or are planning to become pregnant. It is not known if JAMP Atazanavir can harm your unborn baby.
• Pregnant women have experienced serious side effects when taking JAMP Atazanavir with other HIV medicines called nucleoside analogues.
• If you get pregnant while taking JAMP Atazanavir you and your healthcare professional will need to decide if JAMP Atazanavir is right for you.
• There is a registry for women who take antiretroviral medicines during pregnancy called the Antiretroviral Pregnancy Registry. The purpose of this registry is to collect information about the health of you and your baby. If you take JAMP Atazanavir while you are pregnant, talk to your healthcare professional about taking part in the registry.
• JAMP Atazanavir passes into breast milk. You should not take JAMP Atazanavir if you are breastfeeding. This is also to avoid transmission of HIV to your infant through breast milk. Talk to your healthcare professional about how to feed your baby.

Infecting others with HIV: JAMP Atazanavir will not stop you from passing HIV to others, although this risk is lower if you take your HIV medicine as instructed by your healthcare professional. You should take steps to avoid this by:

• Using condoms when you have oral or penetrative sex.
• Not reusing or sharing needles, syringes, or other injection equipment.

Blood tests and monitoring: JAMP Atazanavir can cause abnormal blood test results. Your healthcare professional will decide when to perform blood tests and will interpret the results.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
