What is Fintepla?

Fintepla is a prescribed medicine for treating seizures that can be caused by Dravet syndrome and Lennox-Gastaut syndrome in patients who are 2 years old or older.

Fintepla is a federally controlled substance (C-IV) because it is a drug that contains the chemical fenfluramine. Make sure to keep this medication in a safe location to prevent abuse and misuse and also to guard the medicine from theft. Do not distribute your Fintepla to any other person, as it could cause harm to the person receiving it. The sale or distribution of Fintepla is against the law. Contact your physician if you've been using or becoming dependent on prescription drugs, alcohol, or street drugs.

It isn't known whether this medicine has been proven safe or effective for children younger than 2 years old.


Do not use Fintepla if you:

  • Are allergic to fenfluramine as well as any other active ingredients in Fintepla.

  • You are currently taking or, within the last 14 days, stopped taking monoamine oxidase inhibitors (MAOI), serotonin antagonists, and serotonin reuptake inhibitors. When you take these medications together with Fintepla, it could cause a serious or life-threatening issue known as serotonin syndrome.

Valvular heart diseases and hypertension of the pulmonary artery

Issues with the valves of the heart (valvular heart disease) and high blood pressure in the lungs' arteries (pulmonary arterial hypertension) have been linked to the drug fenfluramine.

Your doctor will perform an ultrasoundcardiogram test to test your heart and detect excessive blood pressure within the arteries that supply the lungs before you begin treatment. You should have it every six months throughout treatment and once every 3 to 6 months following the time you have taken your last dose.

Contact your doctor immediately if you experience any of these signs or signs of lung or heart problems while you are receiving Fintepla:

  • Lips with a pinkish hue and your skin (cyanosis)

  • Chest pain

  • A pulse that is irregular

  • A fainting or lightheadedness

  • Feelings of a fast heartbeat that is fluttering (palpitations)

  • Breathing shortness

  • Foot swelling or ankles

  • Apathy or fatigue is especially evident with the increase in physical activity.

The blood pressure rises.

Your blood pressure needs constant monitoring throughout your treatment with Fintepla.

Weight loss and decreased appetite

Fintepla could cause a reduction in appetite and may cause weight loss. The weight of your body should be monitored often, and your dosage might have to be reduced when your weight falls. In certain instances, the treatment might need to be halted.


Consult your physician when you notice an abrupt decrease in your vision or eye discomfort.

Sleepiness, Insomnia, and a lack of energy (lethargy)

Fintepla could cause you to become tired or sleepy. Avoid driving, operating large machinery, or engaging in other risky actions until you are aware of the extent to which Fintepla affects your body.

The use of Fintepla in conjunction with alcohol, depressants, and even Fintepla could cause sleepiness.

Suicidal thoughts and behaviour

As with other antiepileptic medications, Fintepla can trigger suicidal ideas or actions in a small percentage of individuals (about 1 out of 500).

Contact your doctor immediately if you notice any of the above symptoms, in particular when they're new or get worse, if you have any unusual changes in your behaviour or mood, or if you are thinking about suicide or death.

Refrain from treatment.

Do not discontinue using Fintepla without first speaking to your physician. When it is time to stop taking the medication, it is important to do so gradually because stopping medication for seizures in a hurry can result in seizures occurring more frequently or seizures that don't cease (status epilepticus).

Before you take drugs.

Before you take Fintepla, inform your doctor about your medical conditions, especially those that:

  • Are you suffering from heart issues?

  • Have you or someone else experienced a loss of weight?

  • Have you experienced depression or mood issues? suicidal thoughts, depression, or a pattern of behaviours

  • Have you had liver problems?

  • Are you suffering from kidney issues?

  • Are expecting, planning to become pregnant, or nursing.

Talk to your healthcare professional about every medication you are taking, such as prescription and over-the-counter supplements as well as vitamins and herbal supplements.

Be aware of the medications you are taking. Keep a list to show your doctor or pharmacist when you receive new medication.


There isn't any data available on the efficacy of Fintepla for pregnant women. Inform your doctor right away if you're planning to become pregnant.

If you accidentally develop a pregnancy during your treatment with Fintepla and you are pregnant, speak to your physician about joining the North American Antiepileptic Pregnancy Registry. You can enrol in this registry by calling 1-888-233-2334 or visiting The goal of this registry is to gather details about how safe antiepileptic medicines are during pregnancy.
