A new study has found that Botox could help women who suffer from an overactive bladder.
A total of 240 women with weak bladders took part in the research, which was carried out between 2006 and 2009 in the UK and reported in the journal European Urology. The scientists treated 122 women with Botox while the other 118 were given a placebo.
Those women who had the toxin injected directly into the wall of the bladder reported improvements across a wide range of symptoms. They experienced incontinence less than once a day, while the average before treatment was six times a day.
The women wetted themselves less and “leaked” urine less, the researchers found. There was also a significant reduction in the number of times the women felt they needed to rush to the toilet, from eight times a day to three times a day.
Around 40% of those women who had been given Botox were continent after six weeks of treatment and one in three women was still continent after six months.
However, the researchers found that the Botox effect started to wear off after around six months.They also reported side-effects, such as a paralysis in the bladder muscle, which meant some women needed to use a catheter to go to the toilet.
