Patient leaflet - Fintepla 2.2 mg / ml oral solution
1. What Fintepla is and what it is used for
Fintepla contains the active substance fenfluramine.
Fintepla is used as adjunctive therapy to treat seizures (fits) in patients aged 2 years and over who have either a type of epilepsy called Dravet syndrome or one called Lennox-Gastaut syndrome. It can help to reduce the number and severity of seizures.
It is not completely known how Fintepla works. However, it is thought to work by increasing the activity in the brain of a natural substance called serotonin and the sigma 1 receptor, and this may reduce seizures.
2. What you need to know before you or your child takes Fintepla
Do not take Fintepla if:
you or your child are allergic to fenfluramine or any of the other
ingredients of this medicine (listed in section 6)
you or your child have a heart problem such as ‘valve disease’ or
‘pulmonary arterial hypertension’ (high pressure in the arteries of the lungs)
you or your child have taken medicines used for the treatment
of depression called monoamine oxidase inhibitors in the last 2 weeks.
Do not take Fintepla if any of the above applies to you. If you are not sure, talk to your doctor, pharmacist or nurse before taking Fintepla.
Warnings and precautions
Talk to your doctor, pharmacist or nurse before taking Fintepla if:
- you or your child have glaucoma
you or your child have had thoughts about harming or killing
yourself
you or your child are taking a medicine called cyproheptadine,
which is used to treat allergies or to improve appetite.
you or your child have experienced an increase in frequency of
seizures.
you or your child have experienced more sleepiness. If any of the above applies to you or your child (or you are not sure), talk to your doctor, pharmacist or nurse before taking Fintepla.
Tests and checks
Before you or your child start taking Fintepla your doctor must check the heart with an echocardiogram (ECHO). The doctor will check that the valves in the heart work properly and the pressure in the artery between the heart and lungs is not too high. Once you or your child has started taking Fintepla, you will have an echocardiogram check every 6 months for the first 2 years and then once a year. If Fintepla treatment is stopped, you or your child will need to have an echocardiogram 3-6 months after the last dose.
Your doctor should also check your weight before and during your treatment as Fintepla can cause you to lose weight or decrease your appetite.
‘Serotonin syndrome’
Tell your doctor or pharmacist before taking Fintepla if you or your child are taking medicines which can increase the levels of serotonin in your brain. This is because taking these medicines and Fintepla can cause serotonin syndrome, which is a life-threatening condition. Medicines that can increase serotonin levels include:
- ‘triptans’ (such as sumatriptan) – used for migraine
- MAOI medicines – used for depression
- SSRI or SNRI medicines – used for depression and anxiety. Look out for the signs of serotonin syndrome which include:
being agitated, seeing things which are not there (hallucinations) or
passing out
heart and circulation problems such as fast heartbeat, blood
pressure going up and down, high body temperature, sweating
- twitching muscles and being uncoordinated
- feeling or being sick and diarrhoea.
Tell your doctor straight away if you notice any of the serious side effects above.
Other medicines and Fintepla
Tell your doctor or pharmacist if you or your child are taking, have recently taken, or might take any other medicines. This is because Fintepla can affect the way some other medicines work. Also, some other medicines can affect the way Fintepla works.
Fintepla can make you or your child feel sleepy. You or your child may be even more sleepy if you take other medicines such as anti-depressants or alcohol at the same time as Fintepla.
In particular, tell your doctor or pharmacist if you or your child are taking, have recently taken, or might take:
stiripentol, a medicine for epilepsy, as your dose of Fintepla may
need to be reduced
‘triptans’, MAOI, SNRI or SSRI medicines – see above under
‘Serotonin syndrome’
carbamazepine, primidone, rifampicin, phenobarbital and other
barbiturates, phenytoin, and efavirenz, as your dose of Fintepla may need to be increased.
clobazam, valproate and cannabidiol, which are medicines used to
treat epilepsy.
Pregnancy and breast-feeding
If you or your child are pregnant, think you or your child might be pregnant, or are planning to have a baby or are breast-feeding, ask your doctor for advice before taking this medicine.
Driving and using machines
Talk to your doctor about driving, using machines, or if you or your child undertake activities such as cycling or other sports, because you or your child may feel sleepy or tired after taking this medicine.
Fintepla contains sodium ethyl p-hydroxybenzoate (E 215) and sodium methyl p-hydroxybenzoate (E 219)
This may cause allergic reactions (possibly delayed).
Fintepla contains sulfur dioxide (E 220)
This may rarely cause hypersensitivity reactions and bronchospasm.
Fintepla contains glucose
This may be harmful to the teeth.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
Fintepla contains sodium
This medicine contains less than 1 mmol sodium (23 mg) per 12 ml, that is to say essentially ‘sodium-free’.
3. How to take Fintepla
Always take this medicine exactly as your doctor, pharmacist or nurse has told you. Check with them if you are not sure.
Your doctor, pharmacist or nurse will calculate the dose volume up to the maximal recommended dose, using the formula:
Weight (kg) x Weight-based dosage (mg/kg) ÷ 2.2 mg/ml = ml dose to be taken twice daily
Always round the calculated dose up or down to the nearest graduation mark, following standard rounding conventions. For example, for a patient that needs a dose of 2.15 ml, the applied volume needs to be rounded up to 2.2 ml as the 3 ml syringe can only deliver 2.1 ml or 2.2 ml. Likewise a volume of 1.13 ml would need to be rounded down to a delivered volume of 1.1 ml. For a patient that needs a dose of 3.15 ml, the applied volume needs to be rounded up to 3.2 ml as the 6 ml syringe can only deliver 3.0 ml or 3.2 ml. Likewise a volume of 4.25 ml would need to be rounded down to a delivered volume of 4.2 ml.
The table below must only be used as a check on the calculated dose volume. Table 1 does not replace the requirement to calculate the specific dose volume.

2 Hold the bottle firmly.
Line up the bottle adapter with the open top of the bottle. Push the bottle adaptor into the bottle with your palm until the adaptor is flush with the top of the bottle.
Leave in the bottle adaptor after using the medicine. Screw the bottle cap onto the bottle with the bottle adaptor left in.
3 Taking the medicine:
Before you measure out the dose, make sure the plunger is pushed all the way into the oral syringe.
Hold the bottle of medicine firmly on a hard, flat surface. Push the tip of the oral syringe into the bottle adaptor until it cannot be pushed further.
4 Hold the oral syringe and bottle together and turn upside
down.
Slowly pull the plunger to draw up the right dose. Hold the oral syringe and bottle together and then turn over. Holding the bottle firmly, gently pull the oral syringe out of the bottle adaptor.
5 Place the tip of the oral syringe against the inside of the
patient’s cheek.
Gently push the plunger until it is fully pressed. There will be a small volume left in the tip of the syringe. This is normal. Do not squirt the medicine into the back of the throat as this may cause choking.
6 Place the cap back on the bottle and turn until it stops.
Always leave the adaptor in place in the bottle.
7 Cleaning the syringe:
Rinse the oral syringe with cold water and allow it to air dry after each use.
Rinse the inside of the syringe and the plunger. Cold water can be pulled into the syringe with the plunger and pushed out several times to clean the syringe. It is okay to separate the plunger from the syringe to rinse each part. Do not use detergent to clean the syringe and plunger.
Do not clean the syringe and plunger in a dishwasher. The syringe and plunger must be completely dry before the next use.
If you or your child take more Fintepla than you or your child should

If you or your child forget to take Fintepla
Take it as soon as you remember it. However, if it is nearly time to
