Why Neuropathy Sufferers Are Sacrificial Lambs To Big Pharma Profits

Today's post from psychiatryadvisor.com (see link below) is an important one for neuropathy sufferers, who go to the doctor and are prescribed antidepressants as a first line entry drug to control the pain and other symptoms. We are so desperate to find something to control our symptoms that we accept the doctor's advice and follow a course of drug treatments that frequently involve anti-depressants, anti-seizure drugs and others which carry a high risk of serious side effects. Why do doctors prescribe these things and why do we accept it as if it's the most normal thing in the world? Because there's no alternative and there hasn't been for decades. Yet it's wrong on so many counts but still we're stuck between a rock and a hard place. Amitriptyline heads the list in this article but reading on, you'll come across several other drugs commonly prescribed for nerve pain. The dangers to patients, especially if they are on drugs for other conditions and the cause of their neuropathy, are clear and alarming, yet nothing changes. Yes there are other drugs and treatments, supplements and therapies but these are only brought into play after the patient has already travelled though the standard list and found them all to be unsatisfactory. The fact that many end up on opioids, says more about the nature of the pain than the value of the drug but it's clear that opioids aren't the only land mines on the neuropathy patients' path. If you're on these drugs for nerve pain then you need to have a serious discussion with your doctor. The time for change is long past; now it's time for action!
 

Antidepressant Death Found Most Often With Amitriptyline Tara Haelle, MS   February 24, 2017 

 Death and serious outcomes resulting from overdose or poisoning from drugs used to treat depression more than doubled during the last decade and a half, found a recent study, with amitriptyline topping the list. Fatal cases overall increased by 32%, and amitriptyline accounted for approximately 2 of 5 deaths from antidepressants, the results showed.

"Unfortunately, the same medications that are given to patients to treat depression can become the vehicle for a serious suicide attempt," reported J. Craig Nelson, MD, from the University of California at San Francisco, and Daniel A. Spyker, PhD, MD, from the Oregon Health and Science University in Portland. "Because many suicide attempts are impulsive, readily available medications may be chosen."

Suicides involving poisoning increased 38.5% from 2000 through 2014, with medications comprising the vast majority of these (89%-92%), the study notes.

The researchers analyzed all records from the National Poison Data System for single exposures of psychotropic medications in people aged 12 years and older from 2000 to 2014. Their query included 48 drugs used to treat depressive and related mood disorders, including antidepressants, atypical antipsychotics, anticonvulsants, lithium, and others.
Nearly a million exposures (962,222) occurred from these medications, with the incidence more than doubling during the 15-year period. The patients were an average age of 35.8 years, and 62.8% were women. Just more than half the exposures (51.4%) were suspected suicide attempts, which also accounted for 66.9% of cases with serious outcomes and 74.1% of the fatal cases. Only 10% overall involved intentional misuse or abuse, and 1 in 5 involved therapeutic mistakes.

Instead of calculating rates, the researchers calculated indices for morbidity and mortality: each index represented the proportion of deaths and/or serious cases out of 1000 exposures.

"The most common clinical events in patients with serious outcomes (frequencies;10%) were drowsiness/lethargy (42.3%), tachycardia (40.7%), hypertension (18.6%), agitation/irritability (17.5%), hypotension (13.4%), confusion (13.2%), tremor (12.4%), and conduction disturbance (10.2%)," the authors reported.

The highest indices of morbidity and mortality occurred with tricyclic and monoamine oxidase inhibitor drugs, but high morbidity indices also occurred from lithium, quetiapine, olanzapine, bupropion, and carbamazepine. The drugs associated with higher mortality indices included, in decreasing lethality, lithium, venlafaxine, valproic acid, bupropion, quetiapine, olanzapine, ziprasidone, carbamazepine, and desvenlafaxine.

"Relative to other compounds, tricyclic antidepressants were associated with higher rates of acidosis, cardiac conduction problems, respiratory depression, and seizures," the authors reported. Amitriptyline was responsible for two thirds of all tricyclic antidepressant exposures and 39.5% of deaths from all antidepressants.

"Arguably one of the most important public health implications of our data is that the prescribing of amitriptyline should be reconsidered when safer alternatives are available," the authors wrote.

Monoamine oxidase inhibitors, although representing a small percentage of exposures, involved high rates of hypertension and confusion and increased creatinine and fever. Among second-generation antidepressants, bupropion had the highest rate of seizures and hallucinations, as well as a high mortality index.

Quetiapine and olanzapine had comparatively higher rates of coma and respiratory depression, and the authors note that effects from respiratory depression "can be additive and may become clinically relevant in vulnerable persons, such as patients with sleep apnea."
Higher rates of bradycardia, confusion, and renal problems, such as elevated creatinine, oliguria, polyuria, and renal failure, occurred with lithium than with other drugs.

"Lithium poses a dilemma for clinicians," the authors noted. "It is one of the most dangerous drugs in overdose, and it is one of the only drugs that has been shown to reduce suicidality in depressed patients."

The authors concluded that serious outcomes, including deaths, from drugs used to treat depression have been increasing more rapidly than such outcomes from other drugs, likely in part because depressed patients are already at higher risk for suicide.

"As a consequence, clinicians need to be aware of the potential risks when they prescribe antidepressants and other drugs used in the treatment of depression," the authors wrote.
