Chloral hydrate

Pronunciation

Generic Name: chloral hydrate (KLOR-uhl HYE-drate)
Brand Name: Somnote

Chloral hydrate is used for:

Treating sleep disorders. It may be used to prevent symptoms of alcohol withdrawal or to treat existing withdrawal symptoms. It may also be used to produce sedation or sleep before certain procedures, or to relieve anxiety due to certain procedures or substance withdrawal. It may also be used to treat other conditions as determined by your doctor.

Chloral hydrate is a nonbarbiturate sedative and hypnotic. It works by depressing the central nervous system (brain). This causes drowsiness and helps you to fall asleep. It is less likely to cause a slower breathing rate than barbiturate-type sedatives/hypnotics.

Do NOT use chloral hydrate if:

  • you are allergic to any ingredient in chloral hydrate
  • you have moderate to severe liver or kidney problems, severe heart problems, or severe inflammation of your stomach
  • you are currently taking dofetilide, H1 antagonists (eg, astemizole, terfenadine), or sodium oxybate (GHB)

Contact your doctor or health care provider right away if any of these apply to you.

This may not be a complete list of all interactions that may occur. Ask your health care provider if chloral hydrate may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use chloral hydrate:

Use chloral hydrate as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Chloral hydrate may be taken with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
  • Swallow chloral hydrate whole. Do not break, crush, or chew before swallowing.
  • Take chloral hydrate with a full glass of water or other liquid to reduce stomach upset.
  • If you miss a dose of chloral hydrate and you are taking it regularly, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use chloral hydrate.

Important safety information:

  • Chloral hydrate may cause drowsiness or dizziness. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to chloral hydrate. Using chloral hydrate alone, with certain other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks.
  • Avoid drinking alcohol or taking other medications that cause drowsiness (eg, sedatives, tranquilizers) while taking chloral hydrate. Chloral hydrate will add to the effects of alcohol and other depressants. Ask your pharmacist if you have questions about which medicines are depressants.
  • Chloral hydrate is not recommended for use in CHILDREN; safety and effectiveness have not been confirmed.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, discuss with your doctor the benefits and risks of using chloral hydrate during pregnancy. Chloral hydrate is excreted in breast milk. If you are or will be breast-feeding while you are using chloral hydrate, check with your doctor or pharmacist to discuss the risks to your baby.

Chloral hydrate may be habit-forming and lead to DEPENDENCE if used in high doses or for a long period of time. If you are on long-term or high dosage therapy, you may have WITHDRAWAL symptoms (eg, convulsions, tremor, stomach and muscle cramps, vomiting, sweating) if you suddenly stop taking chloral hydrate. Do not stop therapy abruptly or change dosage without asking your pharmacist or doctor. Discuss overuse with your doctor or pharmacist.
