Is it OK to take Finlepsin 200 Retard instead of regular Finlepsin 200?

No, you should not swap Finlepsin 200 tablets for the Retard version yourself, even though they both contain the same active ingredient carbamazepine.

Finlepsin 200 is an immediate-release tablet, while Finlepsin 200 Retard releases the drug gradually over a longer period of time, which means it releases the drug slowly and ensures its stable concentration in the blood around the clock, while regular Finlepsin works for a shorter period. This change in the form of the medicine may affect the level of carbamazepine in the blood, so it may be necessary to adjust the dose or frequency of tablets. For this reason, the replacement should be carried out in accordance with the doctor's recommendation.
