Barbiturates

  • These are older sedative-hypnotic drugs that are rarely prescribed due to their potential for dependence and overdose. Examples include phenobarbital and secobarbital.

Melatonin Receptor Agonists

  • These drugs work by targeting melatonin receptors in the brain and are used to regulate sleep-wake cycles. Examples include ramelteon (Rozerem).

Antihistamines

  • Some over-the-counter antihistamines like diphenhydramine (Benadryl) and doxylamine (found in certain sleep aids) have sedative effects and can be used for short-term sleep problems.

Herbal and Natural Remedies

  • Certain herbal supplements and natural products like valerian root, chamomile, and lavender oil are used as mild sedatives or sleep aids. However, their effectiveness varies from person to person.

Other Sedative-Hypnotic Medications

  • This category includes miscellaneous drugs like quetiapine (Seroquel), which is an atypical antipsychotic sometimes used off-label for its sedative properties.
