1. What Chloroquine & proguanil Anti-Malarial Tablets are and what they are used for
The name of your medicine is ‘Chloroquine & Proguanil Anti-Malarial Tablets’. It is referred to as ‘Anti-Malarial Tablets’ in the rest of this leaflet.
Your Anti-Malarial Tablets contains two types of tablets:
- Proguanil Hydrochloride.
- Chloroquine Phosphate.
Both medicines belong to a group of medicines called ‘anti-malarials’.
‘Anti-malarials’ can be used in certain parts of the world to help prevent malaria. This is a serious disease spread by mosquitoes. Your Anti-Malarial Tablets will give some degree of protection (prophylaxis) against malaria in certain countries. They can be used when it is necessary to take more than one type of medicine at the same time to help prevent malaria.
Medicines to help prevent malaria (malaria prophylaxis) are recommended for:
- People travelling to countries where malaria occurs
- People living in malaria areas who are not immune to malaria.
These people have little or no immunity to malaria, so they are at risk of severe attacks.
You must get medical advice on which anti-malarial medicines to take.
You must ask your doctor or pharmacist if these Anti-Malarial Tablets are suitable for the part of the world you are visiting.
Avoiding mosquito bites
When you are taking this medicine to prevent malaria, you should also reduce the chances of being bitten by mosquitoes.
- Wear light-coloured, long sleeved clothing and long trousers when you are outside after sunset.
- Use insect repellent creams or sprays on parts of your body not covered by clothing.
- Sleep in a properly screened room or under a mosquito net.
- Spray to kill any mosquitoes that may have entered rooms in spite of screening.
If you have a high temperature
No medicine can be guaranteed to protect against malaria in every case. If you have a high temperature (fever) during your visit to a malaria area, or up to a year after returning home, you should suspect malaria. Contact a doctor straight away and let him or her know you have visited a malaria area.
2. What you need to know before you use you Anti-Malarial Tablets
Do not use these Anti-Malarial Tablets if:
- If you are allergic to proguanil, chloroquine or any of the other ingredients in the tablets (see section 6: Contents of the pack and other information).
- You are taking a medicine called amiodarone (used to control the heart rate). Chloroquine may increase the risk of uneven heart beats (cardiac arrhythmias) when it is taken at the same time as amiodarone. Check with your doctor or pharmacist if you are not sure.
Warnings and precautions
Check with your doctor or pharmacist before taking your medicine if:
- You have ever had epilepsy, convulsions or fits.
- You have ever had problems with your liver or kidneys.
- You have ever been told that you have a rare disease of the blood pigment called ‘porphyria’ or anyone in your family has it.
- You have a scaly condition of the skin called psoriasis.
- You have a muscle problem called ‘myasthenia gravis’. Chloroquine can increase the symptoms of this condition. It can reduce the effect of medicines used to treat this condition (neostigmine and pyridostigmine).
- You have a blood problem called ‘glucose-6-phosphate dehydrogenase deficiency’. Chloroquine may damage blood cells in people with this condition.
If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before using your Anti-Malarial Tablets.
Chloroquine can cause lowering of the blood glucose level. Please ask your doctor to inform you of signs and symptoms of low blood glucose levels. A check of the blood glucose level may be necessary.
Chloroquine may cause heart rhythm disorders in some patients: caution should be taken when using chloroquine, if you were born with or have a family history of prolonged QT interval, if you have acquired QT prolongation (seen on ECG, electrical recording of the heart), if you have heart disorders or have a history of heart attack (myocardial infarction), if you have salt imbalance in the blood (especially low level of potassium or magnesium, see section “Other medicines and your Anti-Malarial Tablets”).
If you experience palpitations or irregular heart beat during the period of treatment, you should inform your doctor immediately. The risk of heart problems may increase with increase of the dose. Therefore, the recommended dosage should be followed.
If you go into hospital, tell the medical staff you are taking both proguanil and chloroquine.
If you live in a country where malaria occurs, you may already be slightly immune to the disease. You must ask a doctor or pharmacist for advice before you take anti-malarial medicines.
Other medicines and your Anti-Malarial Tablets
Please tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This includes medicines that you buy without a prescription and herbal medicines.
Amiodarone (used to control heart rate) must not be taken at the same time as chloroquine (see section 2: What you need to know before you take chloroquine).
Tell your doctor or pharmacist if you are taking any of the following medicines. This is because chloroquine may affect the amount of these medicines in your blood.
- Praziquantel (used to treat infections of the bowel and bladder caused by parasites).
- Cyclosporine (mainly used by transplant patients but also used to treat rheumatoid arthritis and psoriasis).
- Anti-convulsant medicines (used to prevent convulsions and fits).
- Digoxin (used to treat heart problems).
Also tell your doctor or pharmacist if you are taking any of the following medicines:
- Warfarin or other medicines used to prevent blood clots. Proguanil may increase the effect of these medicines.
- Medicines known to affect the rhythm of your heart. This includes medicines used for abnormal heart rhythm (antiarrhythmics), for depression (tricyclic antidepressants) for psychiatric disorders (antipsychotics), for bacterial infections or against malaria (e.g. halofantrine).
- Mefloquine, taken to prevent malaria may increase the risk of convulsions or fits when taken at the same time as chloroquine.
- Levothyroxine (thyroid medicine).
- Medicines used to treat epilepsy, as chloroquine may reduce their effectiveness.
- Agalsidase (used to treat Fabry disease), as chloroquine may reduce its activity.
- Boosted protease-inhibitors (medicines used in the treatment of viral infections, such as HIV/AIDS), as these may alter the levels of proguanil in your body.
- Cimetidine (used to treat stomach problems). This medicine affects how chloroquine is broken down by your body and may affect the amount of chloroquine in your blood.
- Medicines like kaolin (used for diarrhoea) which are called ‘adsorbents’.
- Antacids (aluminium, calcium and magnesium salts that are used to treat heartburn or indigestion). Antacids may reduce the amount of chloroquine absorbed from your gut. This may mean that the full dose of chloroquine is not absorbed into your body and it will not work properly. Therefore, you should take your antacid dose at least four hours before or after taking your chloroquine dose.
Some medicines (for example, ciprofloxacin, cimetidine, omeprazole, pyrimethamine) may increase the amount of chloroquine in your body and this can cause side effects. It is important that you do not take any additional medicines (either prescribed or non-prescribed) before speaking to your doctor.
If you need a vaccination against rabies, make sure you have it before you start your anti-malarial medicine. If you have your rabies injection at the same time as taking your anti-malarial medicine, your rabies vaccine might not work so well.
If you know you are to have a live oral typhoid vaccination, you must tell your doctor beforehand as your treatment with proguanil might need to be adjusted.
If you are pregnant or may become pregnant, talk to a doctor or pharmacist:
- before you use these Anti-Malarial Tablets,
- before you take any medicines to prevent malaria,
- and before you go to a country where there is malaria.
Proguanil can affect the levels of folic acid in the body, therefore pregnant women taking proguanil should be given supplements that contain folic acid.
- If you are breast feeding, talk to a doctor or pharmacist before using your Anti-Malarial Tablets,
- Although proguanil and chloroquine pass into the breast milk, the amount is not enough to protect your baby from malaria. Therefore, your baby will still need to be given anti-malarial medicines. Ask your doctor or pharmacist who will be able to give you advice,
Driving and using machines
Sometimes chloroquine tablets cause blurred eyesight or make it difficult to focus your eyes.
If this happens to you, do not drive or use any tools or machines.
