Before Using This Medicine

In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For topical tetracyclines, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to topical tetracyclines or to any related antibiotics, such as chlortetracycline for the eye (e.g., Aureomycin); demeclocycline (e.g., Declomycin); doxycycline (e.g., Vibramycin); methacycline (e.g., Rondomycin); minocycline (e.g., Minocin); oxytetracycline (e.g., Terramycin); or tetracycline by mouth or by injection (e.g., Achromycin). In addition, if you are to use the cream form of meclocycline, tell your doctor if you have ever had any unusual or allergic reaction to formaldehyde. Also tell your health care professional if you are allergic to any other substances, such as preservatives or dyes.

Pregnancy—Studies have not been done in humans. In studies in rats and rabbits, chlortetracycline and tetracycline topical preparations have not been shown to cause birth defects or other problems. However, studies in rabbits have shown meclocycline to cause a slight delay in bone formation.

Breast-feeding—It is not known whether tetracycline topical preparations pass into breast milk. Although most medicines pass into breast milk in small amounts, many of them may be used safely while breast-feeding. Mothers who are using any of these medicines and who wish to breast-feed should discuss this with their doctor.

Children—Tetracycline topical solution has been tested on a limited number of children 11 years of age or older and has not been shown to cause different side effects or problems in children than it does in adults. Although there is no specific information about the use of topical chlortetracycline or topical meclocycline in children, they are not expected to cause different side effects or problems in children than they do in adults.

Older adults—Many medicines have not been tested in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information about the use of topical tetracyclines in the elderly.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are using topical tetracyclines, it is important that your health care professional knows if you are using any other topical prescription or nonprescription (over-the-counter [OTC]) medicine that is to be applied to the same area of the skin.

Precautions While Using This Medicine

For patients using either the cream form or the topical liquid form of this medicine for acne:

• Some people may notice improvement in their acne within 4 to 6 weeks. However, if there is no improvement in your acne after you have used this medicine for 6 to 8 weeks or if it becomes worse, check with your health care professional. The treatment of acne may take up to 8 to 12 weeks before full improvement is seen.
• If your doctor has ordered another medicine to be applied to the skin along with this medicine, it is best to wait at least 1 hour before you apply the second medicine. This may help keep your skin from becoming too irritated. Also, if the medicines are used too close together, they may not work properly.
• The liquid form of this medicine may also cause the skin to become unusually dry, even with normal use. If this occurs, check with your doctor.
• This medicine may cause faint yellowing of the skin, especially around hair roots. This may be more easily seen in people with light complexions. The color may be removed by washing. However, the medicine should be left on the skin as long as possible. Do not wash immediately after applying the medicine. To do so will keep the medicine from working properly. If the yellow color is bothersome during the daytime, the medicine may be applied after school or work and again at bedtime, unless otherwise directed by your doctor.
• Treated areas of the skin may glow bright yellow under ``black"" (ultraviolet or UV) light such as that used in some discos. To help reduce or avoid this, apply the medicine later in the evening or wash it off before exposure to ``black"" light.
• You may continue to use cosmetics (make-up) while you are using this medicine for acne. However, it is best to use only ``water-base"" cosmetics. Also, it is best not to use cosmetics too heavily or too often. They may make your acne worse. If you have any questions about this, check with your doctor.

For patients using the topical ointment form of this medicine:

• If your skin infection does not improve within 2 weeks, or if it becomes worse, check with your health care professional.
