Allergy medicine breaks a fast, as it contains ingredients that stimulate the digestive system and disrupt the fasting state. When fasting, it is important to abstain from consuming anything that can trigger an insulin response or promote digestion.

Unfortunately, allergy medicine falls into this category. Although it may provide relief from allergies, the ingredients in allergy medication can interfere with the fasting process. This includes over-the-counter antihistamines, which often contain sugar or artificial sweeteners. Additionally, allergy medicine may contain other ingredients that can cause an insulin response, breaking the fast.

Therefore, it is advisable to avoid taking allergy medicine while fasting to fully reap the benefits of intermittent fasting or any other fasting routine.
