How It Works
Temazepam belongs to a class of drugs called benzodiazepines. It works by slowing down activity in the brain. This helps you to relax and fall asleep.
How to Take It
Take temazepam capsules right before you go to bed. The usual dose for adults is 15 mg, but some may need 7.5 mg or 30 mg. If you are elderly or weak, your doctor may start you on 7.5 mg. Talk to your doctor about the right dose for you.
Pregnancy & Breastfeeding
Tell your doctor if you are pregnant or plan to become pregnant. It is not known if temazepam will harm your unborn baby. Talk to your doctor if you are breastfeeding.
Missed Dose
If you miss a dose, skip it and take your next dose at your regular time. Do not take two doses at once.
Storage

Serious Warnings
Taking temazepam with opioid medicines can cause very serious problems, including slowed breathing, coma, and death. Only take them together if there are no other options. Temazepam can be misused or lead to addiction, which can result in overdose or death. Using temazepam for a long time can cause you to become dependent on it. Stopping it suddenly can cause life-threatening withdrawal symptoms. Your doctor will slowly lower your dose to prevent withdrawal.
Known Drug Interactions
Temazepam Nitrazepam Lorazepam No Dose Adjustment Temazepam, Nitrazepam, Lorazepam: For benzodiazepines which are not metabolized by CYP3A (e.g., temazepam, nitrazepam, lorazepam), a clinically important interaction with clarithromycin is unlikely.
Mechanism: These two drugs do not interfere with each other because temazepam is not broken down by the same liver process that clarithromycin affects.
What to do: No dose changes are usually needed when taking these two medications together. You can follow your normal schedule.
7.6 Temazepam Under steady-state conditions for duloxetine (20 mg qhs) and temazepam (30 mg qhs), the pharmacokinetics of duloxetine were not affected by co-administration.
Mechanism: These two medications do not change how the body processes duloxetine when they are taken together.
What to do: No special changes are usually needed when taking these two drugs at the same time.
Other Drugs Clinical effect Concomitant use of COCs may decrease systemic exposure of acetaminophen, morphine, salicylic acid, and temazepam.
Mechanism: Estradiol can cause your body to get rid of temazepam faster than usual, which might make it less effective.
What to do: Your doctor may need to monitor how well your sleep medicine is working and adjust the dose if needed.
CHCs have been shown to decrease plasma concentrations of acetaminophen, clofibric acid, morphine, salicylic acid and temazepam.
Mechanism: Birth control hormones can cause your body to clear out this sleep medicine faster than it should. This can make the sleep medicine feel weaker or not work at all.
What to do: Your doctor may need to adjust your dose of the sleep medication. Tell your provider if you are having trouble sleeping while taking both drugs.
Other Drugs Clinical effect Concomitant use of COCs may decrease systemic exposure of acetaminophen, morphine, salicylic acid, and temazepam.
Mechanism: Birth control pills can cause your body to break down temazepam more quickly, which lowers the amount of medicine in your blood.
What to do: Your doctor may need to adjust your dose of temazepam if you find it is not working as well as it should.

Temazepam capsules are used to treat insomnia. Official labeling lists 7 commonly reported side effects, including Drowsiness, Headache, Fatigue.
Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 21,148 voluntary reports.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
