Contents of the pack and other information
1. What Juneflecad prolonged-release capsules are and what they are used for
Flecainide belongs to a group of medicines that work against heart rhythm problems (known as
anti-arrhythmics). Anti-arrhythmics work by controlling the rate and rhythm of the heart.
Juneflecad prolonged-release capsules are used
- for certain serious heart rhythm problems, which are often expressed as serious palpitations of
the heart or fast heart beat (tachycardia).
- for serious heart rhythm problems that did not respond well to treatment with other medicines,
or when other treatments cannot be tolerated.
2. What you need to know before you take Juneflecad prolonged-release capsules
Do not take Juneflecad prolonged-release capsules:
• if you are allergic to flecainide or any of the other ingredients of this medicine
(listed in section 6)
• if you suffer from another heart condition, different from the heart condition for which you are
taking this medicine. If you are unsure, or if you would like additional information, consult your
doctor or pharmacist
• if you are taking certain other anti-arrhythmics (sodium channel blockers) if you suffer from
Brugada syndrome (a genetic heart disease).
Warnings and precautions
Talk to your doctor or pharmacist before taking Juneflecad prolonged-release capsules if you;
- suffer from a reduced liver function and/or reduced kidney function, since the concentration
of flecainide in the blood may increase. In that event, your doctor may regularly have the
concentration of flecainide in the blood checked,
- are elderly, since the concentration of flecainide in the blood may increase,
- have a permanent pacemaker or temporary pacing electrodes,
- have suffered from heart rhythm problems after heart surgery,
- suffer from severe slow heart beat (bradycardia) or pronounced low blood pressure
(hypotension). These conditions should be corrected before using Juneflecad
- have experienced a heart attack.
A low or high level of potassium in the blood may influence the effect of these capsules. Diuretics,
medicines that stimulate bowel movement (laxatives) and steroids (corticosteroids) may lower the
level of potassium in the blood. In that event, your doctor may have the amount of potassium in
your blood checked.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
Juneflecad prolonged-release capsules with food and drink
Juneflecad prolonged-release capsules should be taken on an empty stomach or at least one hour
before a meal.
Pregnancy and breast-feeding
During pregnancy Juneflecad prolonged-release capsules should only be used if the benefit
outweighs the risks since flecainide has been shown to cross the placenta in patients taking
flecainide during pregnancy. You must consult your doctor as soon as you suspect you are
pregnant, or if you want to have children.
Flecainide is secreted in the mother’s milk. Juneflecad prolonged-release capsules should only be
used during breast-feeding if the benefit outweighs the risks.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby,
ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
If you suffer from side effects such as dizziness, double vision or blurred vision, or if you feel lightheaded, then your ability to react may have been reduced. This may be dangerous in situations
that demand concentration and attentiveness, such as using the road, handling dangerous
machinery or working at heights. If you are unsure whether Juneflecad prolonged-release
capsules are having a negative effect on your ability to drive, discuss this with your doctor.
3. How to take Juneflecad prolonged-release capsules
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your
doctor or pharmacist if you are not sure.
Your doctor will prescribe a personalised dose, adjusted to fit your complaints. Treatment with
Juneflecad prolonged-release capsules will normally be started under medical supervision
(if necessary, in the hospital). Follow your doctor’s advice closely when taking Juneflecad
prolonged-release capsules. Check with your doctor or pharmacist if you are not sure.
When and how should the capsules be taken?
Take the capsules by swallowing them with sufficient fluid (e.g. water). The daily dose is usually
taken split up over the day, on an empty stomach, or at least one hour before meals.
The usual starting dose is between 100 and 200 mg. The dose may be increased by your doctor
to a maximum of 400 mg a day.
More elderly patients
Your doctor may prescribe a lower dose for you. The dose for elderly patients should not exceed
300 mg daily.
These capsules should not be taken by children under the age of 12 years.
Patients with a reduced kidney or liver function
Your doctor may prescribe a lower dose for you.
Patients with a permanent pacemaker
The daily dose must not exceed 200 mg daily.
Patients who are also taking cimetidine (medicine against stomach disorders) or amiodarone
(medicine against heart rhythm problems)
The doctor will check you regularly, and a lower dose will be prescribed for some patients.
During treatment, your doctor will regularly determine the level of flecainide in the blood and
what is known as an electrocardiogram (ECG) of the heart will be taken. A simple ECG must be
taken once a month and a more extensive ECG once every three months. An ECG will be taken
every 2 to 4 days at the start of the treatment and when the dose is raised.
An ECG must be taken more frequently for patients who are receiving a smaller dose than is
usually prescribed. The doctor can adjust the doses at intervals of 6 to 8 days. An ECG will be
taken for these patients at weeks 2 and 3 after the start of the treatment.

If you stop taking Juneflecad prolonged-release capsules
If you suddenly stop taking Juneflecad prolonged-release capsules you will not get withdrawal
