Common side effects of Tamiflu and Relenza include dizziness, vomiting and diarrhea. Other, more serious adverse reactions are rare but can occur, including Stevens Johnson Syndrome, or SJS. SJS is a rare reaction to medication that begins with rashes on the skin that blister over, causing the skin to peel off in sheets. Blisters also can form on the eyes and mouth, which can lead to ocular problems, dehydration, infection and, in severe cases, death.

In Hong Kong in particular, pharmacists are urging the public not to stock up on the antiviral medications, as they say the Chinese government has plenty of the medicines in stock to combat a pandemic should one arise. The urgings come just six years after the deadly SARS virus struck that nation. About 400 Chinese pharmacies – or 95 percent of the market – have joined a campaign to keep residents’ fears at bay. There have been no swine flu cases reported in Hong Kong to date.

“The pharmacies will advise individuals whether the symptoms they have reflect a cold or something more serious such as flu,” head of Pharmacovigilance Kevin Cheung Kin-man told The Standard. “If the symptoms persist for days, people will be advised to consult a doctor. In the meantime, in the case of colds, pharmacists will be able to recommend appropriate over-the- counter medication.”

Health Canada recently updated its report of adverse reactions to some of the more common herbal products, including Echinacea, ginko and St. John’s Wort. According to the report, some people have reported experiencing rashes after taking St. John’s Wort. St. John’s Wort is an herbal treatment for major depression and is available over the counter in the U.S.

Ginseng is another common herb readily available in the U.S. Ginseng is a stimulant taken orally to treat type II diabetes and sexual dysfunction in men. Ginseng also can be found in some popular energy drinks and foods. Studies show that ginseng has been linked to at least one occurrence of Stevens Johnson Syndrome (SJS), a severe adverse reaction to medication.

SJS usually begins with a fever and sore throat and progresses to rashes that cover the skin and mucous membranes. As the condition progresses, the rashes can blister over and cause the skin to fall off in sheets. The mouth and eyes also can blister, which can lead to dehydration, infection and serious eye problems and even blindness.

The International Journal of Pediatric Dentistry also reports that a 10-year-old Indian boy developed severe mouth and eye ulcers and was subsequently diagnosed with SJS after taking an “herbal medication of plant origin” prescribed by a traditional healer for treatment of a fever. According to the book, traditional therapy with herbal preparation (Ayurvedic medicine) is not uncommon in India.

Doctors advise those who experience symptoms of SJS to go immediately to the emergency room.

Chung Wen-hung with Chang Gung Memorial Hospital in Taipei, has discovered that granulysin, a naturally occurring substance in the human body, can attack foreign substances or organisms. This discovery may lead to a therapeutic target for further development of an effective treatment for severe immune-mediated disorders that currently have no satisfactory treatment, according to the report. The report is published in last week’s edition of the biomedical research journal Nature Medicine.

SJS accounts for about half of the cases handled by the Taiwan Drug Relief Foundation. It is a rare and sometimes fatal skin disorder that often is caused by medication. SJS and its more severe form, toxic epidermal necrolysis (TEN), are characterized by painful blistering of the skin and skin lesions.

As the condition evolves and skin cells begin to die, skin can literally slough off. Treatment usually focuses on eliminating the underlying cause, if possible, and controlling the symptoms. Recovery can take several weeks to several months.

Chung’s research also appeared in Nature Medicine four years ago when he discovered a link between carbamazepine, an anti-seizure medicine, and patients with SJS. His discovery prompted the Taiwan Department of Health as well as the U.S. Food and Drug Administration to alert healthcare providers of the possible link and recommend genetic screening for the gene before prescribing the medication.
