Key takeaways
Clonazepam (Klonopin) and doxylamine (Unisom SleepTabs) are used for different purposes and belong to different medication classes. Clonazepam is a prescription-only benzodiazepine used for treating seizures and panic disorder, while doxylamine is an over-the-counter antihistamine used to help with sleep problems. Clonazepam is taken two to three times a day and can be habit-forming, so it’s not usually recommended for long-term use. In contrast, doxylamine is taken once nightly, about 30 minutes before bedtime. Clonazepam can cause side effects like drowsiness, dizziness, and poor movement control, whereas doxylamine commonly causes next-day sleepiness and dizziness. Clonazepam is a controlled substance due to its potential for misuse and dependence, while doxylamine is not a controlled medication and is available over the counter.
