Common questions about side effects of tramadol

Here are answers to some common questions about side effects of tramadol oral tablets. If you have other questions, talk with your doctor or pharmacist.

Will tramadol 50 mg cause fewer side effects than the drug’s other strengths?

It’s possible. Opioid pain relievers, including tramadol, have side effects that are dose related. This means their side effects become more common or more serious with higher dosages.

Examples of these side effects include:

Because of this, doctors may slowly increase the dosage of tramadol oral tablets as needed over time. This can help your body tolerate the drug.

If you’re having side effects that don’t go away or become bothersome, talk with your doctor. They may suggest ways to manage your symptoms or recommend a change in dosage.

Are the side effects of tramadol in older adults different than those in younger adults?

No, older adults won’t have different side effects from tramadol than younger adults. (People ages 65 years and older are usually considered older adults.)

That said, older adults are more likely to have certain side effects with tramadol. This can occur because liver and kidney function tend to slow down with age. Your body depends on the liver and kidneys to help clear drugs from your body. If these organs don’t work as well as they should, drug levels can remain high and cause side effects.

In tramadol’s studies, adults ages 75 years and older were more likely to have side effects that caused them to stop taking the drug. The most common ones were digestive side effects, including constipation. Slowed breathing is also a serious risk for older adults. These side effects occurred in studies for tramadol oral tablet and tramadol extended-release oral tablet.

Due to these risks, doctors usually have people start taking a low dosage of tramadol. In older adults, doctors may increase the dosage more slowly than usual. They may also prescribe a lower maximum dosage.

If you have concerns about the side effects of tramadol oral tablets given your age, talk with your doctor or pharmacist.

Can tramadol cause different side effects in women versus men?

In general, side effects of tramadol oral tablets are the same in males and females.* But there is one exception.

Reports of low blood sodium levels are more common in females older than 65 years of age. This potential serious side effect tends to occur in the first week of treatment. Symptoms can include:

If you have any of these symptoms, call your doctor right away. They may recommend stopping tramadol oral tablets. If you have other questions about the differing side effects between males and females, talk with your doctor.

* Sex and gender exist on spectrums. In this article, we use the terms “male” and “female” to refer to a person’s sex assigned at birth.

How long do side effects of tramadol usually last?

It depends. Some side effects of tramadol oral tablets may be temporary and only last a few days or weeks. But other side effects may last longer.

In studies of tramadol extended-release oral tablet, people reported common side effects at 7, 30, and 90 days of treatment. But it’s unclear whether some of the side effects were related to the drug or to the underlying condition being managed. (Keep in mind that tramadol is prescribed to treat moderate to severe pain.)

In general, people can develop tolerance to mild side effects after taking a medication long term, including tramadol. This means people no longer feel the same side effects at the usual dosage they take.

Tell your doctor if you have side effects that don’t go away or become bothersome. They can evaluate your symptoms and suggest ways to manage them.

Does tramadol cause long-term side effects?

It’s possible. In some cases, tramadol oral tablets may cause long-term side effects. These can occur if you take the drug for a long time. 

That said, the side effects of tramadol oral tablets tend to occur in the first few days of treatment and with dosage increases. But they may also occur later.

Studies of tramadol oral tablet and tramadol extended-release oral tablet lasted up to 90 days. Common side effects were reported throughout these studies. So, it’s possible to have side effects after taking the drug for a long time.

If you develop new side effects while taking tramadol oral tablets, tell your doctor. They can determine whether your symptoms are related to the drug. They may also recommend ways to manage your symptoms. Most side effects of tramadol should go away once treatment is stopped.

Side effects of tramadol in detail

Below you’ll find details on some of the side effects of tramadol oral tablets.

Boxed warnings

Tramadol oral tablets have boxed warnings about the following risks. Boxed warnings are serious warnings from the Food and Drug Administration (FDA). These include:

Risk of misuse and addiction

Tramadol oral tablets have a risk of misuse and addiction. Misuse means a drug is taken in a way other than how it’s prescribed. Addiction means a drug is taken even though it may be causing harm.

Misuse and addiction can lead to overdose and, possibly, death.

Ways to manage

To help reduce the risk of misuse and addiction, take tramadol oral tablets exactly as your doctor prescribes. This means swallowing the tablets and waiting the recommended number of hours before taking the next dose.

If you have concerns about this risk or your use of tramadol oral tablets, talk with your doctor.

Risk of slowed or stopped breathing

Taking tramadol oral tablets can cause slowed or stopped breathing. The risk is higher when you first start taking the drug and after any dosage increases. The risk is also higher for older adults. (People ages 65 years and older are usually considered older adults.)

Ways to manage

Slowed or stopped breathing can lead to death if it’s not immediately treated. If you have any breathing problems while taking tramadol, seek medical care right away.

Risk of accidental ingestion

Accidentally taking tramadol oral tablets can lead to overdose, which can be fatal. Accidentally taking tramadol is especially dangerous in children.

Ways to manage

Store tramadol oral tablets out of the reach of children. Remember, it’s illegal to share prescription drugs, so never give this drug to anyone other than the person it’s prescribed for. It’s also illegal for anyone to take a prescription drug that isn’t theirs. So be sure to keep this drug securely stored.

Risk of life threatening side effects, including death, in children

Children have a high risk of slowed or stopped breathing from tramadol oral tablets. In some cases, this side effect can lead to death.

Certain factors increase this risk even more, including:

  • being a “high metabolizer,” which means your body processes the drug too quickly, leading to very high drug levels in the body
  • having a condition that affects breathing, such as sleep apnea, obesity, lung disease, or a nervous system condition
  • having surgery to remove the tonsils or adenoids
  • taking other medications that can slow breathing

Ways to manage

Due to this risk, tramadol oral tablets should not be taken by children under 12 years of age. Additionally, the drug should not be taken by children ages 12 to 17 years who have the risk factors listed above. Tramadol is not approved for use in people under 18 years of age.

Risk of neonatal opioid withdrawal syndrome

Taking tramadol oral tablets for a long time during pregnancy can cause problems in an infant after birth. This includes a condition called neonatal opioid withdrawal syndrome (NOWS).

With NOWS, the newborn infant may have withdrawal symptoms after birth. This is because they were exposed to the drug while in the womb and their body became dependent on it. (With dependence, your body needs the drug to function like usual.) Without proper treatment, NOWS may be life threatening for the newborn.

Ways to manage

To help reduce the risk of NOWS, tell your doctor about all the medications you take during pregnancy. If tramadol oral tablets were taken during pregnancy, doctors would closely monitor the newborn for withdrawal symptoms.

Risk of harm if taken with certain medications

Taking tramadol oral tablets with certain other drugs can cause dangerous drug interactions. This includes drugs that affect the way your body metabolizes (breaks down and clears) tramadol.

Certain kinds of drugs can cause high levels of tramadol to build up in the body. This increases the risk of serious side effects.

Some drugs could cause tramadol levels to fall too low. This could lead to withdrawal side effects and cause tramadol to not work as well as it should. Withdrawal symptoms occur when you stop taking a drug your body is dependent on. In this case, it’s a matter of tramadol levels falling too low due to an interaction. With dependence, your body needs the drug to function like usual.

Ways to manage

Tell your doctor about all medications you take. Ask whether any could interact with tramadol oral tablets.

Also, using the same pharmacy to fill all your prescriptions can help lower the risk of drug interactions. Doing so allows the pharmacist to check for possible interactions. You can also double-check at the pharmacy by asking about any possible interactions with tramadol.

Risk of harm if taken with benzodiazepines or other central nervous system depressants

Taking tramadol oral tablets in combination with other CNS depressants can be dangerous. It can lead to coma and even death. (The CNS consists of your brain and spinal cord. It regulates many functions in your body.)

CNS depressants are drugs that slow brain function. Examples include alcohol, benzodiazepines, other opioid pain relievers, and several other medications.

Ways to manage

Make sure your doctor and pharmacist know about all medications you take. Ask about possible drug interactions with tramadol. Also, ask whether any medications you take are CNS depressants. If so, your doctor may suggest other treatment options that may be safer for you.

Ways to manage

For mild allergic reaction symptoms, such as a mild rash, call your doctor right away. They may recommend treatments to help manage your symptoms. They’ll also let you know if you should keep taking the medication.

For severe allergic reaction symptoms, such as swelling or trouble breathing, call 911 or your local emergency number right away. These symptoms require immediate medical care because they can become life threatening. If you’ve had a serious allergic reaction to tramadol oral tablets, your doctor may recommend taking a different medication instead.
