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.”

The disease is a contagious respiratory illness. Symptoms usually start suddenly and may include a high fever, headache, tiredness, cough, sore throat, runny or stuffy nose, body aches and diarrhea and vomiting.

One way doctors help patients treat and prevent the flu is with TAMIFLU. Roache Laboratories, the company that makes TAMIFLU, says it is the No. 1 doctor-prescribed flu medication for the treatment of the flu for patients who have been symptomatic for no more than two days.

The medication is approved for both adults and children aged 1 year and older. But according to its safety labeling, and an announcement by the U.S. Chamber of Commerce, during post-marketing rare cases of Stevens Johnson Syndrome (SYS) and toxic epidermal necrolysis (TEN) have been reported by patients using TAMIFLU.

SJS and TEN are serious adverse reactions to medication. There are more than 200 types of medications that have been linked to SJS/TEN, most commonly ibuprofen, antibiotics and anti-seizure medication. The reaction begins with a rash on the skin that blisters over and causes the skin to peel off in sheets. Mucus membranes, such as the eyes and mouth, can blister over leading to serious health concerns such as dehydration, infection, blindness and even death. TEN is the most severe form of SJS, and carries a fatality risk of up to 30-40 percent.

Patients who experience a severe adverse reaction to medication they are taking are encouraged to contact their healthcare provider immediately or go to the emergency room.
