The U.S. Food and Drug Administration (FDA) has proposed the removal of oral phenylephrine, a common ingredient found in numerous over-the-counter cold and allergy medications, from the market. After extensive reviews, the FDA concluded that this decongestant is largely ineffective, prompting a move to eliminate its use in products like Sudafed and Benadryl. This decision aims to protect consumers from spending money on medications that do not provide the promised relief from cold symptoms.
