Fasting can potentially increase the effects of Benadryl, as the drug may be absorbed more quickly and achieve higher concentrations in the bloodstream. This could increase the risk of side effects, such as drowsiness, confusion, and dizziness. It is generally recommended to take Benadryl with food to reduce the risk of adverse effects. If you are fasting, it is important to speak with a healthcare provider before taking Benadryl or any other medication to ensure safe use.
