Pregabalin Abuse, Dependence, and Withdrawal: A Case Report American Journal of Psychiatry

To learn more about the long-term side effects of Lyrica, see “Are there any long-term side effects of Lyrica? If you have questions about your specific risk of side effects from Lyrica, talk with your doctor. Adults ages 65 years and older with kidney problems may be prescribed a lower dose of Lyrica. Lyrica can also affect your mood, which may also contribute to some sexual side effects. If you’re concerned about sexual side effects from Lyrica, talk with your doctor.

  1. In Belfast, we have witnessed a recent increase in the number of patients presenting after recreational abuse of Pregabalin (Lyrica).
  2. There are studies reporting that 15–22% and 3–68% of patients with opioid use disorders abuse gabapentin and pregabalin, respectively [39,40,41,42, 48, 49, 64].
  3. Three other European studies [19,20,21], using data from the national reporting systems, found abuse-related reports on pregabalin.

3 Data Extraction and Assessments

We have only found one study on the human abuse potential of the new gabapentinoid mirogabalin [79]. That study reported that supratherapeutic-dose mirogabalin was better liked by recreational polydrug users than users of placebo. However, there is no information available on the abuse potential of mirogabalin compared with pregabalin and/or gabapentin.

Do Lyrica’s side effects vary depending on the strength, such as 50-mg vs. 75-mg capsules?

If you have any questions regarding previously published content, please contact Lyrica is a prescription medication used to treat pain from damaged nerves caused by diabetes, shingles, and spinal cord injury. Lyrica belongs to a class of drugs called anticonvulsants, which may work by decreasing pain signals from the brain and slowing brain activity. Results Between 02/12–02/13, 10 patients presented to our ED following recreational Pregabalin abuse. Two patients required intubation and ventilation and were admitted to the ICU. In total, nine patients were admitted for a minimum of 24 hours, whilst one patient discharged against advice.

Can I take Lyrica with Cymbalta? If so, are there side effects of taking these drugs together?

Lyndon and colleagues13 studied the respiratory depressant effects of a high intraperitoneal dose of pregabalin with and without medium dose morphine in six mice. A pregabalin bolus given alone depressed mouse minute ventilation to the same extent as a morphine bolus given alone. The respiratory depressant effects of morphine and pregabalin were additive, not multiplicative. Collectively, the published animal studies suggest that gabapentinoids have an independent dose-dependent depressive effect on respiration and can augment the respiratory depression caused by opioids.

It is also important that Google’s tools eliminate repeated searches from the same person over a short period of time. We identified queries containing combinations of the drug names and the abuse-related terms from the set we defined in a previous step. Finally, we filtered the results manually, by dropping out queries unrelated to abuse. For example, while the search query “clonazepam and high blood pressure” contains both the terms “clonazepam” and “high,” it is not related to abuse. Instead, the query “can you get high of pregabalin” is related to abuse and, thus, included to our search results.

Any disagreements regarding inclusion were discussedamong all authors until agreement was reached. Our experts continually monitor the health and wellness space, everything chip carter, son of jimmy and rosalynn, said during tribute service in atlanta and we update our articles when new information becomes available. If you’re concerned about the possible side effects of Lyrica, talk with your doctor.

Future studies are needed to investigate a mechanistic role for neuroinflamation in pregabalin abuse, as well as sex- and age-related mechanisms in pregabalin-induced neurochemical changes. No significant changes in time spent were found in chamber 1 and chamber 2 during the tested phases. These case reports were conducted at the mind matters Unidade Habitacional de Santo António (UHSA), a temporary detention center for undocumented migrants subject to a measure of removal from Portuguese territory carried out by competent authorities. During this period undocumented migrants have access to several services, including social, legal, religious and medical support.

Pregabalin is a GABA-analog that selectively binds to the alpha2 delta subunit of voltage-gated calcium channels. It inhibits the release of excitatory neurotransmitters and increases neuronal GABA levels. Like some other compounds that modulate GABA-ergic neurotransmission, pregabalin might have a potential for abuse. Our patient had a history of drug addiction, which may be important in the reward effect of pregabalin.

However, the rise in popularity of recreationallyused gabapentin is occurring in the US, as well. Smith and colleagues (2015)describe a near 3000% increase in the use of gabapentin to get“high” from 2008 to 2014 among a cohort of 503 prescription drugusers in the Central Appalachian region of the US (44). Several case reports and case series have been published describing non-fatal overdoses of gabapentinoids, most of them including other pharmaceuticals and often with blood supratherapeutic drug concentrations [47]. Regarding fatalities after overdoses of gabapentinoids, there a number of retrospective studies from regional or national post-mortem toxicology registers in Finland [56,57,58] Sweden [30], Germany [102], and the UK [54].

There are studies reporting that 15–22% and 3–68% of patients with opioid use disorders abuse gabapentin and pregabalin, respectively [39,40,41,42, 48, 49, 64]. Although the studies are undertaken in different countries using different methodologies, they support the same general picture. In a study of patients treated for opioid addiction in a substance use disorder clinic in USA [41], 22% misused gabapentin and 7% misused pregabalin.

Correlations between an increased prescription of gabapentinoids and an increased frequency of abuse/misuse [45], and between the numbers of dispensings of pregabalin and pregabalin-positive poisoning deaths [51] have been reported. In the USA, the increased pregabalin use has also been related to ‘off-label’ use as an alternative to opioids for various pain management [108]. Moreover, Rossow and Bramness [109] have shown that the consumption of prescription drugs with an abuse potential is skewedly distributed bath salts effects short- and long-term effects of bath salts and that few excessive users account for a disproportionately high proportion of the drug sales. In recent years, a number of cohort studies concerning abuse of pregabalin and gabapentin have been published indicating that prescription of gabapentinoids as well as abuse/misuse have increased. An Australian study [22] showed that misuse-related ambulance attendances concerning pregabalin increased from 0.3 to 3.3 cases per 100,000 inhabitants from the first half of 2012 to the second half of 2017.

The U.S. Food and Drug Administration (FDA) is warning that serious breathing difficulties may occur in patients using gabapentin (Neurontin, Gralise, Horizant) or pregabalin (Lyrica, Lyrica CR) who have respiratory risk factors. These include the use of opioid pain medicines and other drugs that depress the central nervous system, and conditions such as chronic obstructive pulmonary disease (COPD) that reduce lung function. Although pregabalin is generally well tolerated, euphoria emerges as a dose dependent adverse effect, accompanied by reported improvements in socialization ability and a heightened sense of relaxation. In higher doses, sedative, psychedelic and dissociative effects are also reported. The presence of a euphoric mood may contribute to pregabalin abuse and this can be elucidated by examining its pharmacodynamic and pharmacokinetic characteristics.

For medicinal drugs, it may mean any types of inappropriate use, irrespective of whether there is any dependency involved, and misuse might be accidental or even unrecognized by the patient [13]. The concept of misuse in this review refers to all types of such inappropriate use. ‘Abuse’ on the other hand, is an active and recognized non-medical use of a substance, in most cases linked to dependence/addiction and (often) involving higher doses than normal [14]. Addiction or drug addiction is a neuropsychiatric disorder characterized by a recurring desire to continue taking the drug despite harmful consequences [15]. Although individual studies included in this review may have used slightly different definitions when discussing the results, we used the above-stated definitions.
