Luminal Inj Side Effects

See also How to Use section.

Dizziness, unwanted drowsiness, tiredness, loss of appetite, nausea, vomiting, or staggering walk/clumsiness may occur when you first start using the medication but tend to disappear over time (usually in a few weeks). Less common side effects may include headache, constipation, nightmares, and increased dreaming. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

To prevent constipation, maintain a diet adequate in fiber, and drink plenty of water. If you become constipated while using this drug, consult your pharmacist for help with selecting a laxative (e.g., stimulant-type with stool softener).

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur:

mental/mood changes (e.g., confusion, agitation, hallucinations, anxiety, inability to think clearly/quickly)
slow heartbeat
fainting

Tell your doctor immediately if any of these rare but very serious side effects occur:

signs of liver problems (e.g., persistent nausea/vomiting, abdominal pain, chalky white stools, brown urine, severe tiredness, weakness, severe loss of appetite, yellowing eyes/skin, itchiness)
bone pain/break

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including:

rash
itching
swelling
severe dizziness
trouble breathing

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
