Retin-A
is a Vitamin-A derivative used effectively in the treatment
of Acne Vulgaris. Although the exact mechanism of action is
unknown, Retin-A, used as a topical application, is thought
to loosen and expel existing acne plugs in the skin and prevent
new lesions from forming. Retin-A directly attacks the primary
cause of acne, the plug.
Patient
instructions are available with Retin-A. Read them carefully
before using. Apply a thin layer of Retin-A to affected
area at bedtime. Wash hands immediately after use. Using
Retin-A more frequently or in excessive amounts does not
improve the results, but may increase side effects. Avoid
applying Retin-A near the eyes, mouth, or open cuts since
this medication can irritate sensitive skin. Acne may appear
to worsen when Retin-A is first used; continue therapy.
It may take three to six weeks before the full benefits
of Retin-A are seen.
Side Effects
Immediately
after applying Retin-A, the skin may feel warm or mild stinging
or redness may occur. Some peeling of the skin may occur.
These effects should subside as your skin adjusts to Retin-A.
If they persist or become bothersome, inform your doctor.
Retin-A may also increase sun sensitivity.
Precautions
Retin-A can increase sensitivity to sunlight,
wind and cold. Avoid prolonged exposure to the sun and sunlamps.
Wear protective clothing and use an effective sunscreen.
Retin-A should be used during pregnancy only if clearly
needed. It is not known if tretinoin appears in breast milk.
Consult your doctor before breast-feeding. Use mild soap
when washing your face. Do not wash face excessively. Abrasive
soaps, cleansers, medicated creams or lotions can increase
skin irritation. Consult your doctor or pharmacist about
their use. Use other acne preparations with caution while
using Retin-A .
Drug Interactions
Inform your doctor about all the medicines
you take with and without a prescription.
Missed Dose
If you miss a dose of Retin-A, use it as
soon as remembered; do not use if it is almost time for
the next dose, instead, skip the missed dose and resume
your usual dosing schedule. Do not "double-up" the dose
of Retin-A to catch up.
Storage
Store Retin-A at room temperature away from
sunlight. Keep Retin-A and all medications out of the reach
of children.
Notes
Cosmetics may be used, but clean skin thoroughly
before applying Retin-A.
