It is recommended to try taking Reactine™ for allergies/itching for 7 days to see if it helps with the symptoms. If the symptoms persist after 7 days, it would be advisable to consult a doctor. Additionally, it is suggested to monitor the symptoms over the next 2 to 3 days and then make a decision on whether to seek medical advice or not. Finally, if the symptoms reoccur in the future, it is advisable to seek further medical attention.
