Precautions while using Myrac
It is very important for your doctor to check the progress of you or your child during regular visits. This allows your doctor to see if the medicine is working correctly and to decide if you should continue taking it. Blood and urine tests may be needed to check for unwanted effects.
If your or your child's symptoms do not improve or get worse after 12 weeks of treatment, contact your doctor.
Using this medicine while you are pregnant can harm your unborn baby. It may also cause birth defects if the father is using it when his sexual partner becomes pregnant. If you become pregnant while using this medicine, tell your doctor immediately.
Birth control pills may not work as well while you are using minocycline. To prevent pregnancy, use an additional form of birth control with your pills. Other forms include condoms, a diaphragm, or contraceptive foam or jelly.

Contact your doctor immediately if you experience fever, rash, joint pain, or tiredness. These could be signs of an autoimmune syndrome where the body attacks itself.
