1. What Zidovudine is and what it is used for
Zidovudine capsules, hard contains the active ingredient zidovudine, which belongs to a group of medicines called antiretrovirals. Zidovudine does not get rid of HIV infection; it reduces the amount of virus in your body, and keeps it at a low level. It slows down the progression of human immunodeficiency virus (HIV) infection, which can lead to Acquired Immune Deficiency Syndrome (AIDS), in both adults and children.
Zidovudine is used in combination with other antiretrovirals, for the treatment of HIV infected adults and children.
Zidovudine is used in HIV positive pregnant woman for preventing the transmission of the virus from mother to child.
2. What you need to know before you take Zidovudine
Do not take Zidovudine Capsules, hard

Zidovudine for new-born babies
Zidovudine must not be given to some new-born babies with liver problems, including:
- some cases of hyperbilirubinaemia (increased amounts in the blood of a substance called bilirubin which may make the skin appear yellow)
- other problems which cause high levels of liver enzymes in the blood.
Warnings and precautions
Talk to your doctor or pharmacist before taking zidovudine
• Some people taking zidovudine or combination therapy for HIV are more at risk of serious side effects. You need to be aware of the extra risks:
• if you have ever had liver disease (including hepatitis B or C)
• if you're seriously overweight (especially if you're a woman)
• if you're diabetic and using insulin.
Talk to your doctor if any of these applies to you. You may need extra check-ups, including blood tests, while you're taking your medication. See Section 4 for more information.
Look out for important symptoms
Some people taking medicines for HIV infection develop other conditions, which can be serious. You need to know about important signs and symptoms to look out for while you're taking zidovudine.
Please read the information in Section 4 of this leaflet. If you
have any questions about this information or the advice given: Talk to your doctor.
Other medicines and Zidovudine
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Don't take these medicines with Zidovudine
• stavudine, used to treat HIV infection
• ribavirin or injections of ganciclovir to treat viral infections
• rifampicin, which is an antibiotic.
Some medicines can make it more likely that you'll have side effects, or make side effects worse
These include:
• sodium valproate, used to treat epilepsy
• aciclovir, ganciclovir or interferon, used to treat viral infections
• pyrimethamine, used to treat malaria and other parasitic infections
• dapsone, used to prevent pneumonia and treat skin infections

Pregnancy, breast-feeding and fertility Pregnancy
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
If pregnant women who are HIV-positive take zidovudine, they are less likely to pass the HIV infection on to their unborn babies.
Zidovudine and similar medicines may cause side effects in unborn babies; if it does, these effects won't show up until after the baby has been born. Even so, the benefit of protecting your baby from getting HIV is greater than the risk of your baby getting side effects.
If you've taken zidovudine while you were pregnant, your baby may be given extra check-ups (which may include blood tests), to make sure it's developing normally.
Breast-feeding
Women who are HIV-positive must not breast-feed, because HIV infection can be passed on to the baby in breast milk.
A small amount of the ingredients in zidovudine can also pass into your breast milk.
If you are breast-feeding, or thinking about breast-feeding:
Talk to your doctor immediately.
Driving and using machines
Zidovudine can make you dizzy and have other side effects that make you less alert.
Don't drive or operate machinery unless you're feeling well.
You will need regular blood tests
For as long as you're taking zidovudine your doctor will arrange regular blood tests to check for side effects. There's more information about these side effects in Section 4 of this leaflet.
Stay in regular contact with your doctor
Zidovudine helps to control your condition, but it is not a cure for HIV infection. You need to keep taking it every day to stop your illness getting worse. You may still develop other infections and illnesses linked to HIV infection.
Keep in touch with your doctor, and don't stop taking zidovudine without your doctor's advice.
Protect other people
HIV infection is spread by sexual contact with someone who has the infection, or by transfer of infected blood (for example, by sharing injection needles). You can still pass on HIV when taking this medicine, although the risk is lowered by effective antiretroviral therapy.
Discuss with your doctor the precautions needed to avoid infecting other people.

4. Possible side effects
During HIV therapy there may be an increase in weight and in levels of blood lipids and glucose. This is partly linked to restored health and life style, and in the case of blood lipids sometimes to the HIV medicines themselves. Your doctor will test for these changes.
Treatment with zidovudine often causes a loss of fat from legs, arms and face (lipoatrophy). This loss of body fat has been shown to be not fully reversible after discontinuation of zidovudine. Your doctor should monitor for signs of lipoatrophy. Tell your doctor if you notice any loss of fat from your legs, arms, and face. When these signs occur, zidovudine should be stopped and your HIV treatment changed.

Other possible side effects of combination therapy for HIV:
Some other conditions may develop during HIV treatment.
Old infections may flare up
People with advanced HIV infection (AIDS) have weak immune systems, and are more likely to develop serious infections (opportunistic infections). When these people start treatment, they may find that old, hidden infections flare up, causing signs and symptoms of inflammation. These symptoms are probably caused by the body's immune system becoming stronger, so that the body starts to fight these infections.
In addition to the opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also occur after you start taking medicines for the treatment of your HIV infection. Autoimmune disorders may occur many months after the start of treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness beginning in the hands and feet and moving up towards the trunk of the body, palpitations, tremor or hyperactivity, please inform your doctor immediately to seek necessary treatment.
If you get any symptoms of infection while you're taking Zidovudine: Tell your doctor immediately. Don't take other medicines for the infection without your doctor's advice.
Common (may affect up to 1 in 10 people):
• a low red blood cell count (anaemia) or low white blood cell count (neutropenia or leucopenia)
Rare (May affect up to 1 in 1000 people):
• liver disorders, such as jaundice, enlarged liver or fatty liver (yellowing of the skin and whites of the eyes)
• inflammation of the pancreas (stomach pain, nausea and vomiting)
• fits (convulsions)
Lactic acidosis is a rare but serious side effect
Some people taking zidovudine, or other medicines like it (NRTIs), develop a condition called lactic acidosis, together with an enlarged liver. Lactic acidosis is caused by a build-up of lactic acid in the body. It is rare; if it happens, it usually develops after a few months of treatment. It can be life-threatening, causing failure of internal organs.
Lactic acidosis is more likely to develop in people who have liver disease, or in obese (very overweight) people, especially women.
Signs of lactic acidosis include:
• deep, rapid, difficult breathing
• drowsiness
• numbness or weakness in the limbs
• feeling sick (nausea), being sick (vomiting)
• stomach pain.
During your treatment, your doctor will monitor you for signs of lactic acidosis. If you have any of the symptoms listed above, or any other symptoms that worry you:
See your doctor as soon as possible.
Very rare (may affect up to 1 in 10,000 people):
• a failure of the bone marrow to produce new blood cells (aplastic anaemia).
You may have problems with your bones
Some people taking combination therapy for HIV develop a condition called osteonecrosis. With this condition, parts of the bone tissue die because of reduced blood supply to the bone.
People may be more likely to get this condition:
• if they have been taking combination therapy for a long time
• if they are also taking anti-inflammatory medicines called corticosteroids
• if they drink alcohol
• if their immune systems are very weak
• if they are overweight.
Signs of osteonecrosis include:
• stiffness in the joints
• aches and pains (especially in the hip, knee or shoulder)
• difficulty moving.
If you notice any of these symptoms:
Tell your doctor.
Other effects may show up in tests
Combination therapy for HIV can also cause:
• increased levels of lactic acid in the blood, which on rare occasions can lead to lactic acidosis
These effects may show up in the blood tests you'll have while you're taking zidovudine
