From Medscape Medical NewsFDA Puts 16 Drugs on Watch List
Robert Lowes
Authors and Disclosures
April 17, 2012 The US Food and Drug Administration (FDA) today issued its latest quarterly list of drugs to monitor after having identified potential signs of serious risks or new safety information in the agency's Adverse Event Reporting System (AERS) database during the last 3 months of 2011.
The 16 drugs on the list include milnacipran (Savella, Forest Pharmaceuticals), a drug for managing fibromyalgia, with a potential safety issue of homicidal ideation as identified through AERS. A similar concern put milnacipran in the news in 2010 when the consumer watchdog group Public Citizen asked the FDA to no avail to ban the drug on account of adverse events such as suicidal ideation.
The appearance of any drug on the AERS watch list, however, does not mean that the FDA has concluded that the drug actually poses the health risk reported through AERS, the FDA cautioned. It means only that the agency will study these drugs to determine whether there is a causal link. If the FDA establishes this link, it then would consider a regulatory response, such as gathering more information to better characterize the risk, revising the drug's label, or requiring a risk evaluation and mitigation strategy.
Likewise, the FDA said that it is not suggesting that clinicians should stop prescribing any drugs on the watch list, or that patients should stop taking them. It advises patients with questions about watch-list drugs to discuss them with their clinician.

Of 8 Drugs on Third-Quarter 2011 List, 5 Underwent Label Changes
The FDA's watch list covering July through September 2011 was shorter than the list for the last quarter of that year, containing only 8 drugs or drug classes. Since September 2011, 5 of those 8 drugs have undergone label changes involving the safety issues that surfaced in AERS.
For example, the FDA revised the label of dabigatran etexilate (Pradaxa, Boehringer Ingelheim), an anticoagulant, to recommend that clinicians assess renal function before and during therapy and adjust the dose accordingly because the drug's anticoagulant activity and half-life increase in patients with renal impairment. The label change followed postmarketing reports of fatal bleeding events.
Potential Signals of Serious Risks/New Safety Information Identified by AERS, July to September 2011
Product Name: Active Ingredient (Trade) or Product ClassPotential Signal of a Serious Risk/New Safety Information
Additional Information (as of February 15, 2012)*
Adalimumab (Humira, Abbot Laboratories)Golimumab (Simponi, Janssen Biotech)

Dabigatran etexilate mesylate (Pradaxa, Boehringer Ingelheim)
Bleeding events, including hemorrhage with fatal outcome
The Dosage and Administration section of the labeling for dabigatran was updated January 2012 to include information about monitoring renal function in patients taking dabigatran and adjusting dose if necessary because dabigatran's anticoagulant activity and half-life are increased in patients with renal impairment.FDA is continuing to evaluate this issue to determine the need for any further regulatory action.
Diazepam injection (Valium)Propylene glycol toxicity
Infliximab (Remicade, Janssen Biotech)
Sarcoidosis

The European Medicines Agency is also evaluating orlistat for this potential risk.

In reply to 16 Meds on FDA Watchlist includes Savella, Gabapen, posted by Phillipa on April 18, 2012, at 20:53:51
Most manufactured chemical meds are toxic to the human body in one way or another. Add to that the undesired consequences of side effects, the drug impacting other areas besides the target area, and of course risk and danger is involved.
In most cases of reported toxic effects from meds I personally think the problem is in the dosing not the med itself. Doses are much too high with many meds, but most especially in the early stages of treatment. My opinion anyway.
Also opinion, the FDA is pretty much worthless. Except maybe for keeping outright fraudulent meds or outright deadly meds out of the open market. Well, based on recent news of past weeks, maybe that's not even true. They also prevent perfectly good meds with long track records around the world from entering the USA. Example amisulpride.
I don't think the meds should be on a FDA watchlist, the FDA itself should be on a watchlist.

What bothers me and it's not even on a watchlist already declared unsafe is meds like motrin, asa, then say tynelol of arthritis pain but it's not anti inflammatory and It's inflammation. So what do you take? When taking motrin at low doses seems this wierd eczema like rash on parts of body also reacts positively. I'm in a quandry. Heart disease even from calcium/magnesium. So if now tramadol is on the list and it's being given for arthritic pains and fibromyalgia will this be the same as the Cox 2 meds? Phillipa

"I don't think the meds should be on a FDA watchlist, the FDA itself should be on a watchlist."
amen! sometimes i wonder who, if anyone, is trying to change how much control the FDA has.
i just believe many people in the FDA and many doctors need to be locked up in prison. they are nothing but bad for society.

What bothers me is stuff like this example....
Lots of hoopla and attention on newer meds that are beginning to show some risks...when in reality all meds have these risks and what the heck did you expect anyway?....but....the meds that have already killed thousands, tens of thousands of people, or more, are available without a prescription and are common as candy....
I'm talking about Tylenol.
Here is a med that kills people, has killed a lot of people, and yet the focus is on a different med that doesn't have nearly the deadly track record as that one?
Whatever. Anyone who tells me government knows what they are doing, well, that scares me.
