A single injection of Allergan Inc.’s Botox into a woman’s bladder reduces urinary incontinence as effectively as daily drugs and is better at resolving the problem, a U.S. government-funded study found.

Women in the study getting Botox were more likely to develop infections, retain urine and need catheterization.

The findings support use for the condition, which may gain U.S. approval next year.
