Zidovudine capsules, hard contains the active ingredient zidovudine, which belongs to a
group of medicines called antiretrovirals. It slows down the progression of human

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.

if you are anaemic (causing breathlessness on exertion or making you look pale) or

Zidovudine must not be given to some new-born babies with liver problems,
some cases of hyperbilirubinaemia (increased amounts in the blood of a
substance called bilirubin which may make the skin appear yellow)

or infections.
if you have liver or kidney problems.
if you have any physical signs of fat redistribution, accumulation or loss of body fat.
Please speak with your doctor if you have a history of liver disease. Patients with
chronic hepatitis B or C and treated with antiretroviral agents are at increased risk of
severe and potentially fatal liver adverse events and may require blood tests for
monitoring of liver function.

pregnancy) to reduce the risk of transmitting HIV to their unborn child. If you are
prescribed zidovudine earlier than 14 weeks, your doctor will have weighed up the
expected benefits to you against any possible risks to your unborn baby.
Zidovudine is given to the woman up to and during labour and is stopped after delivery.
Note that while use of Zidovudine during pregnancy can reduce the chance that your
baby will get HIV; some may get it even with this treatment.
Ask your doctor or pharmacist for advice before using any medicine.
Zidovudine passes into breast milk, so it is recommended that mothers taking this
medicine do not breastfeed. Breastfeeding may also increase the risk of passing on the
HIV virus to the baby.

There is no data to suggest that zidovudine affects ability to drive or operate machinery.
Be careful driving or operating machinery until you know how treatment with zidovudine
affects you.


Always take zidovudine exactly as your doctor has told you. You should check with your
doctor or pharmacist if you are not sure.

However, you should tell your doctor or your pharmacist, or contact your nearest

precautions to prevent this.

and/or side effect(s) of each other. An interaction can occur during the use of zidovudine
Rifampicin (an antibiotic used for several serious infections) and stavudine
(antiretroviral drug) may reduce the efficacy of zidovudine.
Lamivudine (antiretroviral drug) and Probenecid (used to treat gout) increases
absorption of zidovudine.
Phenytoin (used to treat epilepsy) blood concentrations may alter when
administered along with zidovudine.
Atovaquone (used to treat lung infections), valproic acid (used to treat seizure),
fluconazole (used especially to treat fungal infections) and methadone (used for
chronic pain management) increase the blood concentrations of zidovudine.
Systemic pentamidine (used to treat lung infections), dapsone (used to treat
leprosy), pyrimethamine (used in treatment of malaria), co-trimoxazole (an
antibiotic), amphotericin (used to treat serious fungus infections), flucytosine (used
to treat certain fungus infections), ganciclovir (used to treat infections caused by
viruses) may increase the risk of adverse effects of zidovudine.

feeling sick (nausea)
Common (Affecting at least 1 of each 100 patients)
anaemia, which may cause weakness and shortness of breath

being sick (vomiting)
stomach pain and diarrhoea
liver disorders e.g. jaundice

rash and itching
pain or weakness in muscle
weakness, fever and generalised pain
Rare (Affecting at least 1 of each 10,000 patients)
failure to develop red blood cells, which may cause tiredness or breathlessness
loss of appetite and build up of lactic acid level in the body, that can cause
dehydration and coma
anxiety and depression
sleeplessness (insomnia)

pins and needles sensation, sleepiness, inability to concentrate and fits
disease of the heart muscles (cardiomyopathy). Symptoms of this may include

inflammation of pancreas
liver disorders such as enlarged liver, fatty liver
Nail and skin colour changes
rash (red, raised or itchy)
increased need to urinate (pass water)
enlarged breasts in male patients
chest pain
“flu-like” feeling
Very Rare (Affecting less than 1 out of 10,000 patients”)
severe reduction in blood cells which can cause weakness, bruising or make
infections more likely
Other possible side effects of combination therapy for HIV:
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.
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.
Your body shape may change
People taking combination therapy for HIV may find that their body shape changes,
because of changes in fat distribution:
Fat may be lost from the legs, arms or face.
Extra fat may build up around the tummy (abdomen), or on the breasts or internal
Fatty lumps (sometimes called buffalo hump) may appear on the back of the neck.
It is not yet known what causes these changes, or whether they have any long-term
effects on your health. If you notice changes in your body shape:
Tell your doctor.
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
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.
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.
Symptoms 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.
If any of the side effects gets serious, or if you notice any side effects not listed in this
leaflet, please tell your doctor or pharmacist.
