Warnings

Kidney Use With Care

Flecainide should be used with caution in patients with renal impairment. The maximum initial dose should be 100mg daily and it is recommended to do frequent plasma level monitoring. Some patients with underlying severe renal failure can have a very slow Flecainide clearance and as a result, prolonged half-life.

Alcohol Not Advisable

It is not advisable to consume alcohol with Flecainide as the alcohol may worsen the side effects of Flecainide such as dizziness.

Pregnancy Not Safe

Animal studies have shown that high doses of Flecainide can cause some fetal abnormalities in New Zealand White rabbits. However, there are inadequate human studies on the usage of Flecainide in pregnancy. Some data reported that Flecainide may cross the placenta and thus it should only be used if the benefits outweigh the risks to the fetus.

Driving Not advisable

Do not drive unless you are feeling well. Flecainide may cause side effects such as dizziness or visual disturbances, all of which could affect the ability to concentrate and drive.

Liver Limited Data

Patients with liver impairment should use Flecainide with caution and must be closely monitored.

Lactation Limited Data

Flecainide is found to be excreted in human breast milk, therefore it should only be used if the benefits of treatment outweigh the benefits of breastfeeding to the infant.
