Tetracyclines (Systemic)
Precautions While Using This MedicineIf your
symptoms do not improve within a few days (or a few weeks or months for acne
patients), or if they become worse, check with your doctor.
Oral contraceptives (birth control pills) containing
estrogen may not work properly if you take them while you are taking tetracyclines.
Unplanned pregnancies may occur. You should use a different or additional
means of birth control while you are taking tetracyclines
. If you have
any questions about this, check with your health care professional.
Before having surgery (including dental surgery) with a general anesthetic,
tell the medical doctor or dentist in charge that you are taking a tetracycline.
This does not apply to doxycycline, however.
Tetracyclines may cause your skin to be more sensitive to sunlight than
it is normally. Exposure to sunlight, even for brief periods of time, may
cause a skin rash, itching, redness or other discoloration of the skin, or
a severe sunburn. When you begin taking this medicine:
-
Stay out of direct sunlight, especially between the hours of 10:00
a.m. and 3:00 p.m., if possible.
-
Wear protective clothing, including a hat. Also, wear sunglasses.
-
Apply a sun block product that has a skin protection factor (SPF)
of at least 15. Some patients may require a product with a higher SPF number,
especially if they have a fair complexion. If you have any questions about
this, check with your health care professional.
-
Apply a sun block lipstick that has an SPF of at least 15 to protect
your lips.
-
Do not use a sunlamp or tanning bed or booth.
You may still be more sensitive to sunlight or sunlamps for 2 weeks to
several months or more after stopping this medicine. If you have a severe reaction, check with your doctor
.
For patients taking minocycline
:
-
Minocycline may also cause some people to become dizzy, lightheaded,
or unsteady. Make sure you know how you react to this
medicine before you drive, use machines, or do anything else that could be
dangerous if you are dizzy or are not alert
. If these reactions are
especially bothersome, check with your doctor.
