Når carbamazapin eller en hvilken som helst anden induktor af levermetabolisme (såsom rifampicin) anvendes samtidig med mirtazapin behandling, skal mirtazapindosis muligvis forhøjes.
When carbamazepine or any other inducer of hepatic metabolism (such as rifampicin) is added to mirtazapine therapy, the mirtazapine dose may have to be increased.
