Calcium folinate is one of the B group of vitamins.
Calcium Folinate Injection is used to reduce the side effects of other
medicines (a group of medicines called folic acid antagonists). Examples of
folic acid antagonists are:

• trimetrexate (an antibiotic and anti-cancer medicine)

Taking/using other medicines
Special care is needed if you are taking/using other medicines as some
could interact with Calcium Folinate Injection, for example:
• folic acid antagonists (see section 1 ‘What Calcium Folinate Injection
is and what it is used for’ for examples of these medicines) - the
effectiveness of these medicines will be reduced by calcium folinate
• 5-fluorouracil (anti-cancer medicine) – the effectiveness and side effects
of this medicine will be increased by calcium folinate
• medicines used to treat epilepsy (phenobarbitone, phenytoin, primidone
or succinimides) – the effectiveness of these medicines may be reduced
by calcium folinate. Your doctor may check blood levels of these
medicines and change your dose to prevent increased convulsions (fits)
Please tell your doctor if you are taking or have recently taken any other
medicines, including medicines obtained without a prescription.

Calcium Folinate 3 mg/ml Injection
The following information is intended for medical or healthcare
Further to the information included in section 3, practical information on the
preparation/handling of the medicinal product is provided here.
Incompatibilities have been reported between injectable forms of calcium
folinate and injectable forms of droperidol, fluorouracil, foscarnet and
1. Droperidol 1.25 mg/0.5 ml with calcium folinate 5 mg/0.5 ml, immediate
precipitation in direct admixture in syringe for 5 minutes at 25°C followed by
8 minutes of centrifugation.
2. Droperidol 2.5 mg/0.5 ml with calcium folinate 10 mg/0.5 ml, immediate
precipitation when the drugs were injected sequentially into a Y-site without
flushing the Y-side arm between injections.
Calcium folinate must not be mixed in the same infusion as 5-fluorouracil
because a precipitate may form. Fluorouracil 50 mg/ml with calcium folinate
20 mg/ml, with or without dextrose 5% in water, has been shown to be
incompatible when mixed in different amounts and stored at 4°C, 23°C, or 32°C
in polyvinyl chloride containers.
Your doctor will work out the correct dose of Calcium Folinate Injection
for you and how often it must be given. It will depend upon the folic acid
antagonist medicine you are having.

This medicine will be given to you in a hospital, under the supervision of a
