Is it bad to take NyQuil to sleep?
You should only use NyQuil as directed on the label. NyQuil is used to treat the symptoms of the cold and flu and not as a sleeping agent for insomnia. However, it can help you feel better if you have a cold or flu because it can treat your symptoms which will help you rest easier.
If you are having trouble sleeping, contact your doctor who can help evaluate your symptoms and determine the cause for your insomnia. If medicine is needed, your doctor may be able to prescribe short-term agents to help you sleep better, or recommend an over-the-counter medication.
You should evaluate your sleep hygiene, as well. For example, are there activities, foods or drinks that may be contributing to your insomnia?
- Caffeine found in tea, coffee, colas and chocolate may keep you up if you consume these later in the day.
- Use of electronic devices, like the TV, phone or other devices may emit blue light and block melatonin, which can make it difficult for you to fall or stay asleep.
- Adequate daily exercise (at least 30 minutes most days of the week) can also help with your sleep.
- Settling down at night with a warm cup of milk or taking a soothing bath can help to ease you to sleep.
This is not all the information you need to know about NyQuil for safe and effective use and does not take the place of the directions on the label. Review the full product information, and discuss any questions you have with your doctor or other health care provider.
