what if you swallow listerine

As an Islamic guide, I can tell you that swallowing Listerine accidentally won't generally cause severe harm, but it's not advised due to its alcohol content and strong ingredients. Large amounts can cause health issues like nausea, vomiting or diarrhea. It's recommended to spit it out after use.

Islam prescribes that anything entering the body through the mouth or nose breaks the fast, including Listerine. Therefore, if you accidentally swallow Listerine while rinsing your mouth during fasting hours, it would invalidate your fast.

You can use miswak or a toothbrush without any toothpaste while fasting. It's also advisable to use alcohol-free mouthwashes outside the fasting hours.

You're welcome! Remember to contact a health professional if you swallow a large amount of mouthwash. And always follow the Islamic principles regarding purity and cleanliness. Be mindful of your actions, especially during the sacred time of fasting. May Allah guide us.
