Take special care with Kaletra

Important information
Kaletra is not a cure for HIV infection or AIDS.

People taking Kaletra may still develop infections or other illnesses associated with HIV disease and AIDS. It is therefore important that you remain under the supervision of your doctor while taking Kaletra.

Kaletra does not reduce the risk of passing HIV to others. Appropriate precautions should be taken to prevent passing the disease through sexual contact (e.g. use of a condom) or blood contamination.

Do not take it after the expiry date printed on the bottle or if the packaging is damaged or shows signs of tampering. If it has expired or is damaged return it to your pharmacist for disposal.

Before you start to take it

Tell your doctor or pharmacist if you have any allergies to any other medicines, foods, preservatives or dyes. Tell your doctor or pharmacist if any of the ingredients listed at the end of the leaflet concern you.

Tell your doctor or pharmacist if you have/had any of the following medical conditions:

  • Haemophilia, as Kaletra might increase the risk of bleeding. The reason for this is not known. You may need additional medicine to help your blood clot, in order to control any bleeding.
  • Diabetes, as increased blood sugars have been reported in patients receiving Kaletra.
  • A history of liver problems, as patients with a history of liver disease, including chronic hepatitis B or C, are at increased risk of severe and potentially fatal liver side effects. Regular blood tests may be required to check that your liver is working properly.

Tell your doctor or pharmacist if you are pregnant, intend to become pregnant or are breastfeeding. Pregnant or breastfeeding mothers should not take Kaletra unless specifically directed by their doctor.

It is recommended that HIV-infected women do not breastfeed their infants because there is a possibility that the baby can be infected with HIV through breast milk. Your doctor will discuss the risks and benefits involved.

If you have not told your doctor or pharmacist about any of the above, tell them before you take Kaletra.

Taking other medicines

Kaletra can be taken with acid-reducing agents (such as omeprazole and ranitidine) with no dose adjustment.

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food store.

Other interactions
Kaletra oral solution contains 42% v/v alcohol. While taking Kaletra oral solution you should not take medicines that cause a reaction with alcohol such as disulfiram or metronidazole.

If you are taking didanosine while taking Kaletra oral solution, it should be taken one hour before or two hours after taking Kaletra oral solution with your meal.

Erectile dysfunction medicines (vardenafil, sildenafil, tadalafil)
If you take sildenafil, tadalafil or vardenafil and Kaletra together, you may be at risk of side effects such as low blood pressure, passing out, visual changes and penile erection lasting more than 4 hours.

If an erection lasts longer than 4 hours, you should get medical help immediately to avoid permanent damage to your penis. Your doctor can explain these symptoms to you.

You must not take Kaletra with sildenafil if you also suffer from pulmonary arterial hypertension.

If you are currently using an oral contraceptive or using a patch contraceptive to prevent pregnancy, you should use an additional or different type of contraception (e.g. condom) as Kaletra may reduce the effectiveness of oral and patch contraceptives.

Kaletra does not reduce the risk of passing HIV to others. Appropriate precautions (e.g. use of a condom) should be taken to prevent passing on the disease through sexual contact.


Kaletra may be prescribed in combination with other appropriate medicines. Your doctor will tell you how much to take and when to take it. Take Kaletra only when prescribed by your doctor.

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the bottle, ask your doctor or pharmacist for help.

How much to take and when to take it

The usual adult dose is 400mg/100mg (two 200mg/50mg tablets) or 5mL of the oral solution twice a day i.e. every 12 hours in combination with other anti-HIV medicines. Adult patients can also take Kaletra tablets once daily as an 800mg/200mg dose (four 200mg/50mg tablets) or 10mL of the oral solution once daily.

Kaletra should not be taken once daily with efavirenz, nevirapine, nelfinavir, amprenavir, carbamazepine, phenobarbital and phenytoin.

Kaletra should not be given to children once daily on its own.

For children, your doctor will decide the right dose of oral solution or 100mg/25mg tablets based on the child's height and weight.

Kaletra oral solution can also be used for patients who cannot take tablets.

Take Kaletra at about the same time each day. This will have the best effect on the HIV infection. It will also help you remember when to take your medicine.

How to take it

Swallow the tablets whole with a full glass of water.

It is important that Kaletra tablets are swallowed whole and not chewed, broken or crushed.

Kaletra tablets can be taken with or without food.

Oral Solution
Kaletra is recommended for use in adults and children 2 years of age or older who are infected with HIV.

Take care when dosing children. Dosing should be less than 5mL twice daily for children weighing less than 40kg.

Kaletra oral solution should preferably be taken with meals.

The oral solution dosage syringe has been specially designed to give you the right dose of Kaletra.

This syringe is the only syringe you should use to measure your dose.

Open the childproof cap by pushing down on it with your palm and twisting it counter clockwise, i.e. in the direction of the arrow. Talk to your pharmacist if you have difficulty opening the bottle.

Five dosing syringes are included in each carton of Kaletra oral solution. Ask your pharmacist for instructions on how to use the syringe correctly.

After each dose of Kaletra separate the plunger and the syringe. Wash the plunger and the syringe with dish washing liquid and warm water as soon as you can; you may soak both in soapy water for up to 15 minutes. Rinse the syringe and plunger with clean water. Put the syringes back together and draw up and expel tap water a few times to rinse. Let the syringe dry completely before you use that syringe for dosing.

How long to take it for

Continue taking your medicine for as long as your doctor or pharmacist tells you.

Kaletra helps control your HIV infection but does not cure it. You may continue to develop infections or other illnesses associated with HIV disease while you are taking Kaletra. Therefore, Kaletra must be taken every day.

Do not stop or change the daily dose of Kaletra without first consulting with your doctor.

Kaletra should always be taken every day to help control your HIV infection, no matter how much better you feel.

Using Kaletra as recommended should give you the best chance of delaying the development of resistance to this medicine.

If a side effect is preventing you from taking Kaletra as directed tell your doctor right away.

Always keep enough Kaletra on hand so you don't run out. When you travel or need to stay in the hospital make sure you will have enough Kaletra to last until you can get a new supply.

If you forget to take it

If it is almost time for you to take your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, and then go back to taking your medicine as you would normally.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for hints.

If you take too much (overdose)

Immediately telephone your doctor, pharmacist or Poisons Information Centre (Australia: Telephone - 13 11 26; New Zealand: Telephone - 0800 POISON or 0800 764 766) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much Kaletra. Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention. Keep telephone numbers for these places/services handy.


Things you must do

If you become pregnant while you are taking this medicine, tell your doctor or pharmacist immediately.

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Kaletra.

Tell any other doctors, dentists and pharmacists who treat you that you are taking this medicine.

If you are going to have surgery, tell the surgeon that you are taking this medicine.

If you are about to have any blood tests, tell your doctor that you are taking this medicine. It may interfere with the results of some tests.

Keep all of your doctor's appointments so that your progress can be checked. Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.

Things you must not do

Do not use this medicine to treat any other complaints unless your doctor or pharmacist tells you to.

Do not give this medicine to anyone else, even if they have the same condition as you.

Do not stop taking Kaletra, or lower the dosage, without checking with your doctor.

Do not let yourself run out of medicine over weekends or on holidays.

Things to be careful of

Be careful driving or operating machinery until you know how Kaletra affects you. Kaletra generally does not cause problems with your ability to drive a car or operate machinery. However, as with many medicines, Kaletra may cause dizziness, sleepiness and nausea in some people. Make sure you know how you react to Kaletra before you drive a car or operate machinery.


Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Kaletra.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

Frequently, it is difficult to tell whether side effects are the result of taking Kaletra, effects of the HIV disease or side effects of other medicines you may be taking. For this reason, it is very important to inform your doctor of any change in your condition. Your doctor may want to change your dose or advise you to stop taking Kaletra.

Ask your doctor or pharmacist to answer any questions you may have.

Tell your doctor or pharmacist if you notice any of the following and they worry you:

  • abnormal liver function tests;
  • diarrhoea;
  • laboratory test results: changes in blood test results (such as blood chemistry and blood account, as well as increased levels of cholesterol, glucose, liver enzymes and triglycerides);
  • headache;
  • difficulty in sleeping;
  • lack of strength and energy;
  • nausea, vomiting, abdominal pain, abnormal stools, indigestion, wind, problems with your digestive system;
  • pain;

  • Changes in body shape due to changes in fat distribution
  • Signs and symptoms of inflammation from previous infections soon after anti-HIV treatment is started
  • Joint stiffness, aches and pains (especially of the hip, knee and shoulder) and difficulty in movement
  • Muscle pain, tenderness or weakness, particularly in combination with these medicines.

The above list includes serious side effects that may require medical attention. Serious side effects are rare.

Some of these side effects can only be found when your doctor does tests from time to time to check your progress.
