The aim of this study was to assess the effect of promethazine on the parameters of ventricular repolarisation: QTc interval and transmural dispersion of
The risk or severity of QTc prolongation can be increased when Promethazine is combined with Anagrelide. Anakinra, The metabolism of Promethazine can be
Promethazine should be used in pregnant women only if the potential can also prolong the QTc interval or taking high doses of promethazine.
Promethazine. Promethazine may increase the QTc-prolonging activities of Azithromycin. Propafenone. Azithromycin may increase the QTc-prolonging activities
Monitor Closely (2)hydroxyzine and promethazine both increase sedation. Use Caution/Monitor. hydroxyzine and promethazine both decrease QTc interval. Use
promethazine. buprenorphine and promethazine both decrease QTc interval. Avoid or Use Alternate Drug. propafenone.
On average the patient's QTc interval changed between promethazine, the promethazine being added for its anticholinergic
buprenorphine and prochlorperazine both decrease QTc interval. Use Caution/Monitor. promethazine. promethazine and buprenorphine both increase sedation. Use
Additive anticholinergic adverse effects may occur. tetrabenazine. tetrabenazine and promethazine both decrease QTc interval. Avoid or Use Alternate Drug. thioridazine. promethazine and thioridazine both increase QTc interval. Avoid or Use Alternate Drug. tranylcypromine. tranylcypromine increases effects of promethazine by Other (see comment).
