The following antibiotics are used
to treat rosacea:
• Erythromycin
• Doxycycline
• Minocycline (Minocin®)
• Tetracycline
Isotretinoin (Accutane®) is a
retinoid or vitamin A analog, which means that its molecular
structure is similar to Vitamin A. It was first approved in
the US in 1982. Capsules come in either 10mg or 40mg doses.
You should take capsules as directed
with fat-containing food. (For example with 2% or whole milk)
The fat in the food helps the medication to be fully absorbed
so that enough can be delivered to your skin to make it effective.
Women who are of childbearing age need
to use two reliable forms of contraception while taking this
medication, and for one month after completing the treatment.
It works slower for rosacea, than
it does for acne treatment.
A larger dose is often required, compared to the dose requirements
when used for treating acne.
Generally not as effective in rosacea, compared to acne.
Isotretinoin basically helps the
sebaceous gland to mature. It does so in several ways. Testosterone
drives this oil gland to produce a number of different oils
that influence the lining of the hair follicle. Accutane®
brings the amount of oils to a more normal level and helps
to change the composition of the oil so that it does not allow
the pores to clog up. It prevents an excess of keratin from
being produced, which means that comedones are not so readily
formed.
This is the most effective therapy currently
available. It can be used to treat your acne, if it is severe,
and will reduce the risk of scarring. However, only doctors
who have experience in its use should prescribe this medication.
This is because regular monitoring, including periodic blood
testing, is necessary. Women and girls who are using this
medication must follow the manufacturer's Pregnancy Prevention
Program.
The following drug interactions have been reported:
• Isotretinoin may reduce the
level of Carbamazepine.
• Avoid isotretinoin if you are allergic to Parabens
(it is a preservative).
• Accutane® (Roche)
FDA-approved:
• Acne
• Severe recalcitrant nodular cystic acne that is not
responsive to other therapy.
