We&#39;re sorry ZzzQuil Nighttime Sleep-Aid Liquid didn’t work for you, Juanita. We know how upsetting it can be when you’re not getting the sleep you need. We&#39;re glad you let us know so we can share your report with our Safety Team. Also, please hold onto the product for a few weeks in case we need more information.<br /> <br />ZzzQuil, like many other over-the-counter sleep medicines, contains diphenhydramine HCI, an ingredient used to treat occasional sleeplessness. Our product is found to be safe and effective when used as directed, so we take a report such as yours very seriously. If your sleeplessness persists continuously, or for more than 2 weeks, we recommend you stop using ZzzQuil and consult a doctor.<br /><br />In the meantime, we&#39;d like to gather more information about the product you have to share with our team, and to help us best assist you. When you have a moment, please give us a call at (877) 881-5813.
