Watch out for
- Melatonin, valerian, ashwagandha, chamomile, lavender, CBD and passionflower may each make you sleepy, and L-theanine may add to the drowsiness a prescription sedative causes. With a prescription sedative, such as a benzodiazepine (for example Xanax or lorazepam) or a sleep medicine such as zolpidem (Ambien), eszopiclone (Lunesta) or zaleplon (Sonata), the sleepiness can add up. You may feel more drowsy and react more slowly than with either one alone, and alcohol makes it worse. Ask the prescriber or pharmacist before you combine them, and do not drive until you know how the pair affects you. Do not stop or change the prescription on your own.
- Monitor for increased sedation when combining L-theanine with alprazolam.
