Acne Medication May Raise Risk of Eye
Infections
Large study found teens taking Accutane were more likely to get
pink eye, styes
Teens who take
the acne medication commonly known as Accutane (isotretinoin) appear to face
twice the risk of eye infections, including conjunctivitis (pink eye) and
styes, a new study says.
Researchers in
Israel collected data on nearly 15,000 teens and young adults taking
isotretinoin to treat acne and compared their rates of eye infections to an
age- and gender-matched group that had acne but was not taking the drugs and to
a third group that didn't take the drugs and didn't have acne. Isotretinoin is
also sold under the brand names Roaccutane, Amnesteem, Claravis, Myorisan and
Sotret.
Within a year
of starting the medication, nearly 14 percent of those in the acne medication
group developed an eye infection or dry eyes, compared with almost 10 percent
in the group that had acne but did not take the medications and about 7 percent
in the group that didn't have acne.
Compared to
the acne-free group, those taking isotretinoin were at 70 percent increased
risk of an eye infection over the course of a year. The mean age of
participants was about 16.5 years old.
The most
common problem was conjunctivitis, an inflammation or infection of the membrane
lining the eyelids. About 4 percent of teens taking isotretinoin developed
conjunctivitis, compared with 2 percent of those without acne and not taking
the medication.
Other problems
included hordeolum (or stye, an inflamed oil gland on the edge of the eyelid);
chalazion (a tender, swollen lump in the eyelid due to a blocked oil gland);
blepharitis (inflammation of the eyelash follicles), dry eyes or eye pain, the
researchers said.
Isotretinoin
treats acne by reducing oil production from the sebaceous glands, among other
effects. But isotretinoin also disrupts function of the meibomian glands, or
oil glands inside the eyelids, explained study co-author Gabriel Chodick, head
of the epidemiology and database research unit at Maccabi Institute for
Healthcare Services Research in Tel Aviv, Israel.
The meibomian
glands help keep the eyes lubricated. Less lubrication may mean the eyes are
irritated, itching and burning, prompting people to rub them and introduce
bacteria. It's also possible that less lubrication makes it easier for bacteria
to take hold, said Dr. Jonette Keri, an associate professor of dermatology and
cutaneous surgery at the University of Miami Miller School of Medicine.
The good news
is that most side effects of the drugs can be prevented using artificial tears
to keep the eyes lubricated, experts said.
"In case
of any meaningful side effect, such as significant eye irritation, itching,
redness, pain, tearing, excessive tearing, patients are advised to consult with
their physician before making any decisions regarding therapy
discontinuation," Chodick said.
The study was
published recently in the Archives of Dermatology.
Keri said
vision side effects from acne medications are well known to most dermatologists.
She tells patients who wear contacts and are starting the medications to use
eye drops to combat dry eyes, but that they may have to discontinue wearing
contacts while they're on the drug if that doesn't help enough.
"What's
interesting is that the researchers found eye problems associated with the
drugs peak at about four months after starting the medication, so I'm going to
tell my patients to really watch their eyes around month four," she added.
Patients
usually take isotretinoin for about five to eight months, she noted.
