How effective are birth control pills at treating intermenstrual bleeding?

The oral contraceptive pill is usually very effective at treating intermenstrual bleeding for most women depending on the cause. Most oral contraceptive brands should work, but there are some brands which are supposed to be better at treating menstrual abnormalities than others. If the first brand that you have been prescribed doesn't seem to work so well at controlling your menses, then see your gynaecologist who can then prescribe you an alternative brand with perhaps a different dosage and different hormonal derivatives to try.
