How Long Does Diazepam Take To Work


Diazepam is an antianxiety drug that is used to treat anxiety disorders and seizures. It can be taken by mouth, rectally or injected into a muscle. Diazepam belongs to a group of drugs called benzodiazepines. These are used as sedatives or hypnotics to treat anxiety, insomnia and sleep disorders. They work by increasing the action of a naturally occurring chemical in the body called gamma-aminobutyric acid (GABA). GABA is an inhibitory neurotransmitter that helps reduce nerve cell activity which can lead to feelings of relaxation and calmness.

How Long Does Diazepam Take to Work?

Recently been prescribed diazepam and wondering how long does diazepam take to work? The time it takes for diazepam to work varies depending on the route of administration. As a rule of thumb, oral diazepam takes 3-4 hours to work, rectal diazepam takes 6-8 hours, and sublingual (SL) diazepam takes 30 minutes.

What Is Diazepam?

Diazepam is a benzodiazepine short-acting sedative-hypnotic class of drugs used to treat anxiety and insomnia. Benzodiazepines act as central nervous system depressants, which means they slow down your brain’s activity to cause a calming effect. If you have anxiety or an active mind in general, taking diazepam can help you relax so that it’s easier for you to fall asleep. The effects of diazepam can be felt within 30 minutes after taking it and last for up to 12 hours (although there are other side effects that may persist even after the drug has worn off).

Diazepam is used in adults and children older than 2 years old with severe insomnia due to psychiatric conditions such as panic attacks or generalized anxiety disorder (GAD). It may also be used in adults with alcohol withdrawal symptoms or acute seizures caused by epilepsy. Diazepam isn’t used alone but usually comes as part of combination therapy with other medications like antidepressants.

When is Diazepam Prescribed?

Diazepam is a benzodiazepine and is prescribed for the following conditions:

  • Anxiety disorders
  • Insomnia
  • Alcohol withdrawal
  • Muscle spasms
  • Muscle relaxation

How Long Does it Take for Diazepam to Work?

How long does diazepam take to work – the answer to this question depends on how you take the drug. Diazepam works fastest when taken orally, with effects appearing within 20 minutes of ingestion. When it is injected intravenously, the onset of action is rapid but typically lasts only 30-60 minutes, while intramuscular injection results in a slower onset (approximately 1 hour). Rectal administration takes even longer because the absorption rate of diazepam through this route is very low.

What is the Best Time to Take Diazepam?

If you’re taking diazepam for anxiety or muscle spasms, there are a few things to keep in mind when it comes to timing your dose.

Diazepam is a long-acting benzodiazepine and can be taken once daily or twice daily. You should take this medication with food, but it’s not necessary to eat beforehand. If you have trouble swallowing pills, it’s helpful to crush the tablet and mix it with food or drink just before taking the medication. This will help ensure that the drug gets absorbed into your system as quickly as possible so that its effects can begin working almost immediately after ingestion (and not hours later).

Diazepam should not be taken with alcohol because it increases sedation—which could lead to unconsciousness if too much alcohol is consumed at one time by someone who has taken diazepam recently enough before ingesting alcohol.

How Long Does it Stay in Your System?

How long diazepam stays in your system depends on the dose. The half-life of diazepam is between 10 and 15 hours, so it can take up to two days for you to be clear of it. The half-life of diazepam is longer in people with liver problems, so if you have a medical condition that affects how well your body metabolizes drugs, talk to your doctor before taking any sedatives.

What is the Recommended Length of Time for Taking Diazepam?

How long you take diazepam will depend on the condition it is being used to treat. Diazepam is not prescribed for long-term use, and some doctors may only recommend one or two weeks of treatment. For example, if you are taking diazepam to help with insomnia, this medication may help you sleep better while you are in the hospital or while recovering from surgery. However, your doctor will likely recommend that you stop using diazepam when your symptoms improve so that you can have a normal sleep schedule once again.

If you are taking diazepam for anxiety problems or panic attacks, this medication may be used as needed during times when stressful situations arise or when symptoms flare up suddenly. Patients who need more than one dose per day should talk with their doctor about how often they should take their dose so they don’t abuse the drug or develop a dependence on it over time

Are There Any Side Effects Associated with Taking Diazepam?

You may feel drowsy after taking diazepam. You may also feel dizzy, lightheaded, or weak. Do not drive or operate machinery for at least 6 hours after taking diazepam. Diazepam can cause blurred vision and double vision, so avoid driving or operating machinery until you know how this medication affects you.

Some people using benzodiazepines get a headache with nausea and vomiting (referred to as “benzodiazepine withdrawal syndrome”). If this happens to you:

Take the medicine only when it is needed to relieve symptoms of anxiety; never take more than your doctor recommends; do not change the dose without talking with your healthcare provider first; if these side effects continue or worsen over time while taking lorazepam treatment options are available that are less likely to cause these side effects

It takes a shorter time for diazepam to work when taken orally than other routes of administration. It’s a short-term treatment that should be used for no longer than 4 months. However, those who are dependent on the drug can take it longer under medical supervision. Don’t use diazepam if you are pregnant, breastfeeding or have liver problems. If you feel drowsy after taking diazepam, don’t drive or operate machinery.
