Neurontin and Lyrica Adverse Effects: The Saga Continues

Neurontin and Lyrica Adverse Effects: The Saga Continues

These are likely among those who have had lung or kidney issues in the past, or who are using gabapentin with other substances (medicinal or otherwise). The loss of balance and difficulty with movement coordination tend to present more in elderly individuals, who are at a high risk for falling injuries. Children tend to experience mood changes and periods of depression when taking gabapentin.

For vincristine in both cells a concentration of 100 nM was needed to achieve a significant cell injury. Cell morphology was monitored by phase-contrast microscopy using inverted microscopy (Olympus, Tokyo, Japan). No direct cytotoxic effects were observed after incubating PC12 cells for 24 hours with increasing concentrations of gabapentin or pregabalin using MTT cytotoxicity assays. Furthermore, in preinjured PC12 and DRG neurons, neither gabapentin nor pregabalin prevented or enhanced the cytotoxic effects of H2O2 or vincristine after incubation for 24 hours and 7 days, respectively.

  • “We have solved the longstanding mystery of how this blockbuster drug acts,” said Ben Barres, MD, PhD, professor and chair of neurobiology.
  • Various physiological processes become affected after continual exposure to drugs, and the change in metabolic rate induced by gabapentin will likely result in unexpected weight gain for these patients.
  • Gabapentin is often prescribed for epilepsy and chronic pain, and its off-label use for other indications is widespread.

And yet gabapentin is a human medication that got the nod from veterinarians. In a review by Keck and colleagues,8 gabapentin was described as effective for where can i buy cheap pregabalin prices panic disorder and social phobia at relatively low dosages. Pregabalin is very effective for a variety of anxiety disorders at dosages of 200 mg BID.

Adverse Effects in Prenatal Development

To assess potential cytotoxic effects of gabapentin or pregabalin, cells were incubated with either 10 or 100 µM of each drug, respectively. According to a recent study, the lower concentration is equal to a dose of about a third of the daily maximum dose of either gabapentin or pregabalin.22 This is likely the situation in patients undergoing medication with those drugs in a normal clinical setting. The higher concentration reflects a “supratherapeutic” dose, which is unlikely to occur under normal clinical conditions.

neurontin and lyrica are highly toxic to new brain synapses

But both syndromes may involve excessive numbers of synaptic connections in local areas of the brain. Despite the MOCA findings, I was not convinced this woman had dementia. I suspected this was a case of alprazolam toxicity, which would require slow tapering to avoid withdrawal symptoms in this already fragile patient.

The Anti-Youth Pill? Alprazolam Toxicity Can Add Years to Brain Age and Appearance

However, to this point it remains unclear whether the observed structural changes are a result of the disease processes underlying pain itself or a consequence of the medications applied. The present study was hence conducted to examine the effects of gabapentinoids on cell survival, morphology, and cytoskeletal integrity by focusing on the pivotal cytoskeletal proteins α-tubulin and neurofilament L (NFL) in healthy and injured autonomic and sensory neuronal cell models in vitro. Similarly to PC12 cells, coincubation with gabapentinoids did not alleviate the α-tubulin-disrupting effects of vincristine or alter the observed injury pattern (Figure 3, G and H). Based on these results, it appears unlikely that short-term application of gabapentin or pregabalin is cytotoxic or has an influence on neuronal changes induced by oxidative or chemical stress. In a next approach, cell injury was induced by exposing PC12 and DRG neurons to either H2O2 as indicated or vincristine (100 nM).

This notion, for instance, is supported by studies showing damaging effects of morphine on fibroblasts and cerebellar Purkinje cells.27,28 Whether gabapentinoids, which are widely used to treat acute and chronic pain, display similar noxious properties on neuronal cells remains unclear. To address this question, 10 µM and 100 µM gabapentin and pregabalin were used in this study. The lower dose was chosen because it is equivalent to the plasma concentration found in patients who received a third of the maximum daily dose of gabapentin (3,600 mg) and pregabalin (600 mg). To explore the ability of short-term (24-hour) exposure of test drugs and chemicals to induce or augment injury in PC12 cells, MTT assays were performed. Results showed that gabapentin or pregabalin alone did not exert cytotoxic effects at a clinically relevant concentration of 10 µM.

Rita Hogan, a canine herbalist, shared her experiences with me about gabapentin for dogs. She reported dogs becoming more aggressive and exhibiting signs of dementia and memory loss. Rita also saw a family member develop signs of senility, memory loss, and confusion with this drug. There have been zero controlled research studies on gabapentin to treat chronic pain. Gabapentin is a relatively simple drug, but its pleasant and relieving effects have raised concerns that it could be abused, either by patients who desperately want alleviation from their symptoms or by recreational users who mix the medication with other substances to enhance the desired effect. Long-term incubation with gabapentinoids does not affect cytoskeletal proteins in dorsal-root ganglion neurons.

Its molecular structure bears a resemblance to the GABA neurotransmitter, which the human brain normally produces to reduce electrical activity in the central nervous system. If a person has a brain that cannot produce sufficient levels of GABA, the results usually present in the form of anxiety or panic disorders, or epileptic seizures. Gabapentin, therefore, introduces GABA-like changes into the brain, diminishing abnormal activity, and giving the patient more mood regulation and protection from seizures. It is the brain’s circuitry of some 100 trillion of these synapses that permit us to imagine, sense, retain information and progress.

Whenever I notice veterinarians widely prescribing a new drug … I like to look at the history of that pharmaceutical. The ones that Big Pharma and conventional vets use to bully the alternative medicine community. Today, my patient is completely off alprazolam and clonazepam and takes 2600 mg of gabapentin daily. Her alprazolam dosage had been tapered to 6 mg daily; she continued taking 1 mg BID clonazepam and started gabapentin on a titration to 300 mg BID. Here’s a case that illustrates the potential for alprazolam to create a dementia-like appearance-not to mention a premature aging of the patient. Gabapentin toxicity could also develop in people who take more gabapentin than they should, whether out of a misguided desire for relief or for recreational purposes.
