Zithromax and Sudden Death

At one time or another, most of us have taken the antibiotic, Zithromax.  It is one of the most commonly prescribed medications for conditions including bronchitis, pharyngitis, sinusitis, and others.  The discussion that follows has to do with Zithromax's side-effects, some of which are potentially life-threatening.  Recently, I have seen a case in my emergency room of sudden cardiac arrest secondary to the cardiac effects of Zithromax.  The FDA has recently warned of this phenomenon.

FDA Warning Regarding Sodium Oxybate for daytime drowsiness

The US Food and Drug Administration (FDA) has issued a warning against use of alcohol and central nervous system depressant drugs (CNS), such as benzodiazepines and opioids, with sodium oxybate ( Xyrem, Jazz Pharmaceuticals) because of the risk for impaired consciousness and respiratory depression.

The drug, used to reduce episodes of cataplexy and treat daytime sleepiness in patients with narcolepsy, is already contraindicated for use with insomnia drugs. The new contraindications are reflected in labeling changes for the drug.

FDA Adds New Potentially Hazardous Drugs to its Watch List

The US Food and Drug Administration (FDA) has added several drugs to its list of products to monitor because of possible signs of serious risks or new safety information. The drugs treat conditions that include cancer, epilepsy, hypertension, and malaria.

The agency spotted yellow flags for these drugs in the FDA Adverse Event Reporting System (FAERS) database during April, May, and June 2012.

Making the FDA's watch list does not mean that the agency has concluded that the drug actually poses the health risk reported through FAERS, formerly known as AERS. Rather, the agency will study the drug to determine whether there is truly a causal link. If it establishes a link, the FDA then would consider a regulatory response such as gathering more data to better characterize the risk, revising the drug's label, or requiring a risk-evaluation and mitigation strategy.

The FDA also is not suggesting that clinicians should stop prescribing watch-list drugs, or that patients should stop taking them, according to an agency press release.

New Practice Guidelines on Carbon Monoxide Poisoning

The first consensus guidelines on how to evaluate, treat, and prevent carbon monoxide poisoning has recently been released and published in the American Journal of Repiratory and Critical Care Medicine.  These guidelines standardize management of carbon monoxide poisoning for clinician, toxicologist, and public health worker, and offer a road map to attorneys prosecuting or defending a carbon monoxide exposure legal action.  You can read more about  these guidelines by obtaining the actual article from the journal.  The citation is Hampson et al, Am J Respir Crit Care Med. 2012, October 18. epub, (ahead of print).  The title of the article is: Practice Recommendation in the Diagnosis, Management, and Prevention of Carbon Monoxide Poisoning.

Death from Oxymorphone

Deaths due to narcotic abuse typically occur by overdose, and consequent respiratory failure.  New data demonstrates a novel cause of death associated with narcotic abuse.  On October 12, 2012 the US Food and Drug Administration (FDA) warned that individuals who abuse the prescription pain medication oxymorphone hydrochloride extended-release tablets (Opana ER, Endo Pharmaceuticals) are at serious risk of developing thrombotic thrombocytopenic purpura (TTP), a blood disorder that can result in kidney failure and death.

According to the FDA, cases of TTP linked to Opana appear to occur only when the drug is injected intravenously.

The FDA notes that in TTP, blood clots form in small blood vessels throughout the body. The clots can limit or block blood flow to the body’s organs, such as the kidneys, brain, and heart.

Platelets help the blood to clot. In TTP, as platelets form blood clots, fewer of them are available to assist with clotting in other parts of the body. This can lead to bleeding under the skin and internal bleeding.

TTP can cause death or lead to other complications with permanent damage, such as kidney failure, brain damage, or stroke.
