Your prescription drugs may have more side effects than you’re told — here’s why

By Mary James, ND

For years the FDA and big drug companies have been telling us they’re gettingmuch-needed new drugs to market faster than ever. The FDA has published studiesbacking up its claims that the new “fast track approval process” isjust as safe as the old, slower method. And certainly the new process cantake just half the time of the old way.

But is the new system really safer? We reviewed the evidence, and found plenty ofreasons to be concerned. You should be too.

Obviously, we all hope that new, lifesaving drugs become available as quickly aspossible. But there are business factors at work here, too. It takes a longtime to develop new drugs, and drug development is an expensive process. Drug companieshave suffered for years from a relative failure to discover breakthrough new products.

This means that as older drugs lose their patents and go generic, drug companiesdon’t have new hit products to replace the lost revenues. Thus they have a financialincentive to use the FDA’s new accelerated approval process to to replenishtheir product line faster.

But you won’t be surprised to learn that faster doesn’t necessarily meanbetter.

What drug companies don’t know can hurt you

According to a 2017 study, nearly a third of recent new drugs had a safety issuethat was identified after the FDA approved the drug for sale. Of the 222 newdrugs put on the market between 2001 and 2010, 71 (or 32%) had a safety issuethat the testing and approval process didn’t uncover. In 43 of the drugs (or19%), the side effect was severe enough to warrant a “black box warning,”which is reserved for side effects that are potentially life threatening. In threecases (or 1.4%), the problem was so severe that the drugs were actually pulled offthe market. But the drugs had already been on the market for years!

For most of the drugs looked at in the study, the product was on the market andin use for anywhere from 3 to 5 years before a pattern of patient safety concernswas found. When you consider the fact that the median review time for FDA-approveddrugs is about 11 months — and half that for fast-tracked drugs — youstart to realize why there’s a problem.

Safety review processes have changed

Fast-tracking first became an option in drug development back in the 1990s, whenCongress passed a law intended to help relieve the backlog of research into drugsneeded to treat life-threatening illnesses and “orphan” diseases. Theconcern was that people were suffering and dying because promising medications justtook too long to get through the arduous, expensive drug safety and efficacy assessmentprocess. The goal with these changes was to get drugs into the hands of patientsfaster if they showed clear superiority to existing treatments (or if they treatedconditions for which there were no existing treatments).

And over the past 20-plusyears, there’ve been some great successes in reaching that goal. Drugs calledimmune checkpoint inhibitors, for instance — many of which received “priorityreview” or fast-tracking from the FDA — have doubled the rate of survivalin patients with the most serious form of skin cancer, metastatic melanoma. Butas is often the case, just because there are successes in some cases doesn’tmean it’s wise to try the process in all cases — because there havebeen some serious problems, too.

One example of how the expedited approval process has gone wrong is Eteplirsen,a drug approved in 2016 for Duchenne muscular dystrophy. This drug’s approvalprocess pitted the FDA’s commissioner against its chief scientist, with thecommissioner calling for expedited approval (in part to assure that research forfurther therapies could get funding from the drug’s sales) and the chief scientistprotesting that the drug was ineffective and offered “false hope” topatients and families struggling with a difficult chronic illness. The commissionerprevailed, and the drug was approved — but many pharma industry watchers weredisturbed by how it was handled. After several years on the market, theredoesn’t seem to be much evidence that it works in the patients who take it,which suggests the chief scientist’s argument against approval was well-founded.

In the three years since the Eteplirsen approval sent shockwaves through the industry,the FDA’s flawed approval process has changed — but not for the better.The recent push to “deregulate” the FDA is cause for concern, and evensome drug company executives have spoken out about it. “In my view it’snuts to ascribe a material portion of the time and cost of drug development to FDA‘regulations’,” one biotech entrepreneur said in an interview.“Lowering the bar for proof is inviting both catastrophe for patients andeven more wasted money in a system that is forced to pay for drugs that don’twork — and may even inflict harm.”

What accelerated drug approvals may mean for women

Unfortunately, quite a few fast-tracked drugs are marketed directly to women. Thedrug industry pushed the FDA to allow direct-to-consumer advertising back in the1980’s, and it now spends over $5 billion on such promotions every year inthe USA alone. Notably, the US is one of the few countries in the world wheresuch advertising is legal, effectively diminishing the role of the doctor in choosingdrugs for her patients. Here are two recent and worrisome examples: first,the drug Xeljanz, which was approved in 2012 for treatment of rheumatoid arthritis — a debilitating autoimmune disease that womenexperience at over twice the rate men do, and usually at a younger age. In February2019, almost 7 years after it first went on the market, post-marketing safety studiesconcluded that a 10-mg twice daily dose of Xeljanz has an increased risk of bloodclots, pulmonary embolism, and death.

Then there’s Addyi, the “female Viagra” approved in 2015 for womenwith unexplained low libido. The FDA approved the sex drug for women despite concerns that combining the drug withdrinking alcohol could cause low blood pressure and fainting — concerns thathad prevented the drug’s approval twice before, in 2010 and again in 2013.Many healthcare providers, including some of the reviewers who assessed the drugfor the FDA in the first place, objected to the approval, arguing that the drug didn’tmeet the standard of providing significant benefits to the patient. Some of theirrelated objections are downright disturbing, among them the fact that the drug’smanufacturer placed “inappropriate pressure … upon the drug approvalprocess by the ‘Even the Score’ campaign, which was partly funded bythe Applicant.”

So many questions

In the case of Xeljanz, why did it take so long to find the problems? One reason:The drug companies gather as little data as possible before submitting their drugfor FDA approval. The drug’s manufacturer, Pfizer, did run a clinical trialassessing drug safety at the 10-mg twice daily dose before the drug’s approval— but the trial ran for just 6 months. Most patients are likely to use ita lot longer than that. There have been more follow-up studies since 2012 —but meanwhile, the drug is already being used in patients and is being advertisedregularly on television and in magazines in an effort to acquire more customers.

This means that drug companies are still learning about their products’ long-termeffects while you’re taking them.

And as Addyi shows, they’re not at all unwilling to put pressure on regulatorsto get drugs to market even when there are good reasons to reject them — tothe point of creating entire PR campaigns (disguised as patient advocacy), to geteven an iffy product over the finish line. How is that good for patients?

Or, as one pharmacology professor put it in the Journal of Pharmacology and Pharmacotherapeutics,““Many drugs that are relatively new to the market find their way out as fast as they entered it. Is expediting drug discovery really solving the unmet needs of society?”

Who’s protecting you?

Step back and consider how these factors work together. Drugs are rushed tomarket without large-scale, long-term trials. This conceals risks that onlyemerge months or years after the drug is certified. But meanwhile, the drugsare advertised directly to consumers. Notably, half of all clinical trialsin the USA are never published -- not even to doctors. And half of all drugprescriptions are off-label, i.e. written for a usage other than what the FDA approved.

So what’s that add up to? Certainly there are cases where the innovativenew drug is a true breakthrough that relieves suffering and saves lives. Butin many if not all cases, it also means that neither you nor your doctor can reallyassess the risk/reward ratio of the drug you’re being given.

 

What can you do? In our view, it boils down to is this:you have to do yourhomework when it comes to treatments, especially when taking medications that arenew to the market (meaning, within the past 10 years).

Watch the ads on TV critically. Usually these adsmanipulate people’s thinking by creating impossible expectations and playingoff our desperation. Also, listen carefully to the list of side effectsat the end of each ad — if they’re recited too quickly for you to hear,look up the drug’s website or third-party review site before discussing itwith your doctor.

Review the drug facts. Every medication comes withan extensive list of side effects, interactions, precautions, and warnings. Usuallythese are in teeny type that no one wants to read. But if you’re consideringa new medication and you’re not sure what it might do to you, go ahead andread at least the “adverse effects” warnings. Then, discuss them withyour practitioner. Sometimes by doing this, you both may find a reason why the drugmight not be your best option.

Explore other, gentler options first — and save the newestoption for last. This is so important! When you’re not feelingwell, it’s tempting to bring out the most powerful solution you can find andapply it in an effort to get rid of your symptoms fast. But as we mentioned above— faster isn’t always better. Work with a health care practitioner whois committed to integrative health and can make recommendations.

A tried-and-true approach that focuses on wellness rather than the latest medicationon the market may not seem like the quickest route to feeling well, but often itoffers less system-wide disruption and fewer unpleasant side effects.
