Birth control pills contain lactose, which is a sugar found in cow’s milk. This means they are not technically vegan as they contain a form of animal produce. If you are vegan, it’s up to you whether you are happy to take birth control pills or not. There are other options like the patch or ring you can use instead. If you are severely lactose intolerant or have a rare condition called galactose intolerance, then you may not be able to take birth control pills.
