1. What Artesunate Amivas is and what it is used for
Artesunate Amivas contains the active substance artesunate. Artesunate Amivas is used to treat severe malaria in adults and children.
After treatment with Artesunate Amivas your doctor will complete your treatment for malaria with a course of anti- malarial medication that can be taken by mouth.
2. What you need to know before you are given Artesunate Amivas
Do not use Artesunate Amivas
if you are allergic to artesunate, to any other antimalarial
treatment that contains an artemisinin (e.g. artemether or dihydroartemisinin) or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
You may develop anaemia, a reduced number of red blood cells, or other blood changes after treatment with this medicine. Some changes to numbers of blood cells can occur while you are being treated and usually recover after stopping treatment for malaria. However, some individuals develop severe anaemia that can occur up to several weeks after completing treatment for malaria. In most cases, the anaemia recovers without any specific treatment. In a small number of cases the anaemia may be severe and require blood transfusion. Your doctor will carry out regular blood tests that can include a direct antiglobulin test to determine if treatment e.g. with corticosteroids, is necessary and monitor your recovery for 4 weeks after you have completed your treatment for malaria. It is important you attend appointments for these check-ups. Talk to your doctor for more information.
Other medicines and Artesunate Amivas
Tell your doctor if you are taking, have recently taken or might take any other medicines. This includes medicines not on prescription. Some medicines should not be taken with artesunate because they could reduce its effect on malaria. Some examples include:
- rifampicin (to treat bacterial infections)
- ritonavir, nevirapine (anti-HIV medication)
- carbamazepine, phenytoin (to treat epilepsy) Some medicines may increase blood levels of artesunate and may increase the risk of side effects. Some examples include:
- diclofenac (to treat pain or inflammation)
axitinib, vandetanib and imatinib (used in the treatment of
certain cancers)
Artesunate may increase or decrease the blood levels of some other medicines. Your doctor will advise you on taking any medicines during artesunate treatment.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, you should talk to your doctor before being given this medicine.
Your doctor will discuss with you the potential risk of taking Artesunate Amivas during pregnancy. Use in the first trimester of pregnancy is not recommended unless your doctor decides that the benefit of treatment for you outweighs the risk to your unborn child. In the later stages of pregnancy, you should only take Artesunate Amivas if your doctor feels that there are no suitable alternative medicines.
If you are or become pregnant during treatment with this medicine, the doctor will report your pregnancy to the manufacturer, who is keeping a record in order to understand any effects that the treatment may have on the pregnancy and the baby.
Traces of this medicine may be present in your breast milk. It is not known if these could have any effect on a breastfed baby. If you are planning to breastfeed, discuss with your doctor whether the benefits of breastfeeding to you and your baby outweigh the potential risk.
Driving and using machines
You should not drive or use machines if you feel tired or dizzy. Artesunate Amivas contains sodium
This medicine contains 193 mg sodium (main component of cooking/table salt) in each single dose. This is equivalent to just under 10 % of the recommended maximum daily dietary intake of sodium for an adult.
As the first and second doses are recommended 12 hours apart, this would supply 386 mg sodium (nearly 20 % of your maximum daily intake).
3. How Artesunate Amivas is given

It is very important that you complete a full course of antimalarial treatment taken by mouth after you have had at least three doses of Artesunate Amivas by injection.

The following information is intended for healthcare professionals only:
Preparation and Administration
The required dose of Artesunate Amivas should be calculated prior to reconstitution:
Dose mg = patient’s weight in kg x 2.4
Only the required number of vials of Artesunate Amivas should be reconstituted when preparing the dose. Remaining unopened vials can be stored in the carton ready for use at the next scheduled dose.
To reconstitute, withdraw 11 mL of the supplied solvent (0.3 M sodium phosphate buffer) with a needle and syringe. Inject into the vial containing the artesunate powder (the final concentration of artesunate is 10 mg/mL when reconstituted). Swirl gently for 5 to 6 minutes until the powder is fully dissolved. Do not shake.
Visually inspect the solution within the vial to ensure that no visible particles remain and there is no discolouration. Do not administer if solution is discoloured or contains visible particles. Inject the reconstituted drug solution IV as a slow bolus over 1-2 minutes. Do not administer via continuous IV infusion. The initial recommended dosage schedule is at
0, 12 and 24 hours. After at least 24 hours (3 doses) treatment, the recommended dosage is once daily until alternative oral anti-malarial medication can be tolerated.
Artesunate Amivas also contains 193 mg sodium per the recommended single dose in a 60 kg adult, equivalent to 9.6 % of the WHO recommended maximum daily intake of 2 g sodium for an adult. As the first and second doses are recommended 12 hours apart, on days when two doses are given in a 24 hour period, then the dose would be 386 mg sodium per day, equivalent to 19.2 % of the WHO recommended maximum daily intake of 2 g sodium for an adult.
Storage of reconstituted Artesunate Amivas solution
Once reconstituted, the Artesunate Amivas solution should be administered within 1.5 hours of preparation. Discard any unusued solution in accordance with local guidelines.
