A commonly used drug combination for nausea in pregnancy is ineffective, according to previously unpublished information from a clinical trial.

Pyridoxine-doxylamine, a sustained-release tablet combining doxylamine 10mg and pyridoxine 10mg is no longer available in Australia but the two separate medicines can be bought over the counter.
