Contents of the pack and other information
Medicinal product no longer authorised
Zerit belongs to a particular group of antiviral medicines, also known as antiretrovirals, called nucleoside reverse transcriptase inhibitors (NRTIs).
These are used to treat Human Immunodeficiency Virus (HIV) infection.
This medicinal product, in combination with other antiretrovirals, reduces the HIV viral load and keeps it at a low level. It also increases CD4 cell counts. These CD4 cells play an important role in maintaining a healthy immune system to help fight infection. Response to treatment with Zerit varies between patients. Your doctor will therefore be monitoring the effectiveness of your treatment.
Zerit may improve your condition, but it is not a cure for your HIV infection. 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.
During treatment, other infections linked to a weakened immunity (opportunistic infections) may arise. These will require specific and sometimes preventive treatment.
If you are allergic to stavudine or any of the other ingredients of this medicine (listed in section 6). Contact your doctor or pharmacist for advice.
If you are taking didanosine, used to treat HIV infection.
Talk to your doctor before taking Zerit.
Before treatment with Zerit, you should have told your doctor:
if you suffer from kidney disease or liver disease (such as hepatitis)
if you have had peripheral neuropathy (persistent numbness, tingling, or pain in the feet and/or hands)
if you have suffered from pancreatitis (inflammation of the pancreas).
Zerit can cause a sometimes fatal condition called lactic acidosis, together with an enlarged liver. This condition usually does not occur until a few months after onset of treatment. This rare, but very serious side effect occurs more often in women, particularly if very overweight. In addition, rare cases of liver failure/renal failure or fatal hepatitis have been reported.
Patients with chronic hepatitis B or C and treated with antiretroviral agents are at increased risk for
severe and potentially fatal liver side effects and may require blood tests for control of liver function.
If you develop one of the following, contact your doctor:
persistent numbness, tingling or pain in feet and/or hands (this may indicate the beginning of peripheral neuropathy, an adverse effect on the nerves), muscular weakness
abdominal pain, nausea or vomiting
rapid deep breathing, drowsiness (which may indicate pancreatitis, liver disturbance such as hepatitis, or lactic acidosis).
In some patients with advanced HIV infection (AIDS) and a history of opportunistic infection, signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started. It is believed that these symptoms are due to an improvement in the body’s immune response, enabling the body to fight infections that may have been present with no obvious symptoms. If you notice any symptoms of infection, please inform your doctor immediately. 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.

During therapy with Zerit there is often a gradual loss of subcutaneous fat (fat found beneath the skin), which is most notable in the face and on the legs and arms. Contact your doctor if you notice such changes.
Bone problems
Some patients taking Zerit may develop a bone disease called osteonecrosis (death of bone tissue caused by loss of blood supply to the bone). The length of combination antiretroviral therapy, corticosteroid use, alcohol consumption, severe immunosuppression, higher body mass index, among others, may be some of the many risk factors for developing this disease. Signs of osteonecrosis are joint stiffness, aches and pains (especially of the hip, knee and shoulder) and difficulty in movement. If you notice any of these symptoms please inform your doctor.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Do not take Zerit if you are taking didanosine, used to treat HIV infection.
Tell your doctor if you are taking any of the following medicines, as undesirable interactions may occur:
zidovudine, used to treat HIV infection
doxorubicin, used to treat cancer
ribavirin, used to treat hepatitis C infection.
For maximum effect, Zerit should be taken on an empty stomach, and preferably at least one hour before a meal. If this is not possible, the capsules may also be taken with a light meal.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.
Pregnancy
You must contact your doctor to discuss the potential side effects and the benefits and risks of your antiretroviral therapy to you and your child. Lactic acidosis (sometimes fatal) has been reported in pregnant women who received Zerit in combination with other antiretroviral treatment.
If you have taken Zerit during your pregnancy, your doctor may request regular blood tests and other diagnostic tests to monitor the development of your child. In children whose mothers took NRTIs during pregnancy, the benefit from the protection against HIV outweighed the risk of side effects.
Breast-feeding
Tell your doctor if you are breast-feeding. It is recommended that HIV-infected women should not breast-feed under any circumstances in order to avoid transmission of HIV to the baby.
Zerit may cause dizziness and drowsiness.
If you are affected, do not drive and do not use any tools or machines.
These capsules contain lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure. Your doctor has defined your daily dose based on your weight and individual characteristics. Please follow these recommendations closely as they will give you the best chance to delay development of a resistance to the medicinal product. Do not change the dose on your own. Continue to take this medicine until your doctor tells you otherwise.
For adults whose body weight is 30 kg or more, the usual starting dose is 30 or 40 mg given twice daily (with approximately 12 hours between each dose).
To obtain optimal absorption, the capsules should be swallowed with a glass of water, preferentially at
least one hour before a meal and on an empty stomach. If this is not possible, Zerit may also be taken with a light meal.
If you have problems swallowing capsules you should ask your doctor about the possibility of
changing to the solution form of this medicine or you could carefully open the capsule and mix its contents with some food.
For children whose body weight is 30 kg or more, the usual starting dose is 30 or 40 mg given twice daily (with approximately 12 hours between each dose).
Children older than 3 months, whose body weight is less than 30 kg, should receive 1 mg/kg twice
daily.
If you have taken too many capsules or if someone accidentally swallows some, there is no immediate danger. However, you should contact your doctor or the nearest hospital for advice.
If you accidentally miss a dose, then simply take your normal dose when the next one is due. Do not take a double dose to make up for a forgotten dose.
The decision to stop using Zerit should be discussed with your doctor.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
When treating HIV infection, it is not always possible to differentiate between unwanted effects caused by Zerit, or those caused by any other medicines you may be taking at the same time, or by the complications of the infection. For this reason, it is important that you inform your doctor of any change in your health.
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 stavudine (Zerit) 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 stavudine. 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, Zerit should be stopped and your HIV treatment changed.
