Frequently asked questions

Below are answers to some commonly asked questions about trazodone oral tablet and its dosage.

Can trazodone be used in dogs? If so, what is the dosage?

Trazodone has been studied for use in dogs. One possible use is for stress relief during veterinary visits.

Remember that dogs and humans have very different needs, which include dosages of medications. That’s why you should not give your dog trazodone or any medication before talking with a veterinarian. Doing so could be harmful to your pet.

Find out whether your veterinarian feels your dog could benefit from trazodone. If they do, they can prescribe a safe dosage for your dog.

Is there a dosage of trazodone for sleep, anxiety, or pain?

No, the drugmaker of trazodone does not have a recommended dosage for sleep, anxiety, or pain. Trazodone is not approved to treat these conditions.

But doctors might prescribe trazodone off-label for these conditions. With off-label use, doctors prescribe a drug for a purpose other than its approved uses.

Trazodone has a side effect of drowsiness. If you have drowsiness while taking trazodone, talk with your doctor. They may suggest that you take a lower dose or take your dose at bedtime.

Be sure to take the dosage of trazodone your doctor prescribes. They will choose the dosage that best fits your needs. If you have any questions about your dosage, ask your doctor.

Does an older adult have to take a lower dose of trazodone?

The drugmaker suggests caution in prescribing trazodone to older adults. These are usually people ages 65 years and older.

Studies of trazodone didn’t show different side effects in older adults compared with those in other age groups. But studies of other antidepressant drugs did. Keep in mind that trazodone is an antidepressant.

If you are an older adult, talk with your doctor about the best dosage of trazodone to meet your needs. They will consider your age, your overall health, and other medications you take.

Can trazodone be taken long term?

Yes, doctors usually prescribe trazodone oral tablet as a long-term treatment. If you and your doctor determine that it’s safe and effective for your condition, you’ll likely take it long term.

If you have questions about how long you should take trazodone oral tablet, talk with your doctor.

Is there a risk of withdrawal with trazodone?

It depends. (Withdrawal describes symptoms that can occur when you stop taking a drug on which your body is dependent. With dependence, your body needs the drug to function like usual.)

If you stop taking an antidepressant, the symptoms of depression might return. (Trazodone is an antidepressant.) This is sometimes called discontinuation syndrome rather than withdrawal.

Trazodone and other antidepressants have been studied for withdrawal symptoms. But there isn’t enough evidence yet to determine whether trazodone has a risk of withdrawal.

If you are interested in stopping trazodone treatment, talk with your doctor. They will likely plan to gradually decrease your dosage to safely stop the treatment.

How trazodone is taken

Trazodone oral tablet is swallowed. You’ll usually take it two or three times per day. You should take trazodone after a meal or snack.

Sometimes you may need to split a trazodone tablet for your correct dose. Trazodone tablets are scored, which means the middle has a groove for easier splitting. If you have to split your trazodone tablet, talk with your doctor or pharmacist. They will show you how to split the tablet correctly.

Your doctor may advise that you take this medication around the same time each day. This keeps a consistent amount of the drug in your body. And that can help it work more effectively.

If trazodone makes you drowsy, your doctor may advise that you take it before bedtime.

If it’s hard for you to swallow tablets, view this article. It provides suggestions on how to swallow medications that come in pill form.
