Preventing Medication Withdrawal

FAQ: Lowering your risk of experiencing withdrawal from medications commonly used to treat pain

All medications have side effects, contraindications and risks along with benefits. Special medication classes used for the treatment of pain have special features to consider. Your healthcare provider along with your pharmacist should speak with you about these before prescribed or dispensed, and each time they are renewed or refilled.  Some medication used for pain relief causes your body to adapt to them. Physical dependence is the body’s way of accepting the medication as familiar or natural, which results in withdrawal symptoms when the medication is abruptly discontinued or rapidly reduced. Physical dependence is not the same as addiction (or substance use disorder), where cravings or obsession for the “high” or “escape” is present along with other features of substance abuse.

Here is a FAQ to assist.

Anticonvulsants

Q: I am taking an anticonvulsant medication for nerve pain. How do I recognize withdrawal?

A: If you are being treated by a healthcare provider with prescription anti-seizure medication, and you suddenly stop taking them, you can experience serious side effects, including withdrawal, which can be unpleasant and in some cases, life-threatening.

Anyone who takes anticonvulsants on a regular basis can develop physical dependence.  How long this takes to set in is unknown. Anticonvulsants used for nerve related pain include:

  • Gabapentin (Neurontin)
  • Topiramate (Topamax)
  • Pregabalin (Lyrica)

Quitting “cold turkey” may cause major withdrawal symptoms: the sudden drop in dose may also worsen your pain which will send your symptoms on a downward spiral, and set your treatment back several weeks or months. Seizures have been reported, which can be dangerous.

Q: What are the signs and symptoms of anticonvulsant withdrawal?

A: The most common effects are:

  • Sleepiness and overall fatigue
  • Extreme Nausea/Flu-like symptoms
  • Dizziness
  • Difficulty driving/concentrating
  • Confusion/Fuzzy thinking
  • Rapid heart beat
  • Agitation/Anxiety
  • Seizures
  • Inability to move/ ongoing rigid state for several days or weeks (catatonia)
  • Intestinal bleeding
Q: After anticonvulsants are stopped when does withdrawal occur?

A: Some people develop withdrawal symptoms after stopping the medication for a few days while others have no withdrawal symptoms even after taking medication for several weeks.

Q: I wish to stop taking these medications. What should I do?

A: Talk to your healthcare provider FIRST! The best way to lower or stop anticonvulsant use is by slowly cutting back on the daily dose of medication over time (taper) under medical supervision. If you recently stopped taking anticonvulsants and are experiencing any withdrawal symptoms, seek medical attention.

Antidepressants

Q: My pain specialist has prescribed antidepressants for chronic pain (depression, anxiety, insomnia)? If I were to suddenly stop taking them, what could happen?

A: Talk to your healthcare provider FIRST! The best way to lower or stop antidepressant use is by slowly cutting back on the daily dose of medication over time (taper) under medical supervision.

If you recently stopped taking benzodiazepines and are experiencing any withdrawal symptoms, seek medical attention IMMEDIATELY:  call 911 or go to the nearest emergency room or urgent care center.

Opioids

Q: I have been taking opioids for pain several times per day and every day over the past several weeks. They have been prescribed by my doctor. I am going back for an appointment this week and wish to stop taking them, but not sure what will happen. What do I need to know?

A: Anyone who takes opioid pain relievers on a regular basis (for more than 1-2 weeks) will develop physical dependence. If you suddenly stop taking them, you can experience serious side effects, including withdrawal, which can be unpleasant. A plan to decrease and stop them needs to be discussed with your healthcare provider.

Q: What medications are considered opioids?

A: Opioids include morphine, oxycodone, oxymorphone, hydrocodone, hydromorphone, methadone, codeine and fentanyl.

Q: What is the difference between opioids and narcotics? I hear my medication called both by health professionals.

A: Opioids (or opiates) are the class of medications derived directly from opium found naturally from the poppy seed (like morphine, heroin) or from synthetic or semisynthetic morphine-like substances (like fentanyl). All opioids except for heroin are legal yet controlled by the U.S. federal government. They are expected to be prescribed for legitimate medical need only.

Narcotic is the legal “catch-all” term for both legal and illegal drugs; according to the DEA fact sheet:  “narcotic” comes from the Greek word for “stupor” and originally referred to a variety of substances that dulled the senses and relieved pain. It is not uncommon for other illegal drugs, such as cocaine, PCP and heroin to be included in this term.

Q: What can cause withdrawal from these medications?

A: Withdrawal symptoms from opioids can occur when:

  • the medication is abruptly discontinued or rapidly reduced, or
  • another medication is given to reverse the effect of the opioid (called an antagonist, like Narcan).
Q: What are the signs and symptoms of opioid withdrawal?

A: They are:

  • Sweating
  • Anxiety
  • Restlessness
  • Insomnia (Inability to sleep)
  • Dilated pupils
  • Nausea/vomiting
  • Diarrhea
  • Abdominal Cramping (pain)
  • Muscle aches
  • Chills (goose bumps)
  • Excessive tearing of the eyes
  • Runny nose
Q: How soon after opioids are stopped can withdrawal occur?

A: This depends on whether the drug is short-acting or long-acting:

 Opioid Types Onset of Withdrawal
Short acting (immediate release) oral opioids 6-12 hours
Long acting (extended release) oral opioids 12-24 hours
Methadone 48-96 hours
Q: What should I do if I wish to stop taking these medications?

A: Talk to your healthcare provider FIRST! The best way to lower or stop opioid use is by slowly cutting back on the daily dose of medication over time (taper).  Opioid taper, particularly for those who have been on long term therapy, should be performed under medical supervision. Underlying medical conditions, like high blood pressure, heart disease and other chronic diseases could become unstable during unplanned or unmonitored withdrawal.

Stimulants

Q: I have been prescribed a stimulant weight loss (attention deficit disorder or to counteract sedation from my pain medication). If I suddenly stop taking them, what can happen?

A: Anyone who takes stimulants on a regular basis (for more than 1-2 weeks) will develop physical dependence. Stopping these medications abruptly can cause serious side effects, including withdrawal, which can be unpleasant.

  • dextroamphetamine mixed salts (Adderall)
  • methylphenidate transdermal patch (Daytrana)
  • Illegal substances such as cocaine and crack are also stimulants.

 

Q: What can cause withdrawal to occur?

A: Withdrawal symptoms can happen when the:

  • Stimulant is abruptly discontinued or rapidly reduced (or)

A: This depends on whether the drug is short-acting or long-acting. For short acting preparations, this can occur within 24 hours of the last dose:

 Types Examples
Short acting (immediate release) oral Dexedrine, Ritalin
Immediate acting oral Adderall, Ritalin SR, Metadate ER
Long acting (extended release) oral Adderall XR, Concerta, Ritalin LA
