Call your doctor when

  • Your child’s condition worsens.
  • Your child experiences an allergic reaction (shortness of breath, swelling in the face, itchiness, pain or pressure in the chest or a rapid pulse). Take your child to the ER immediately.
  • If your child experiences side effects that include a change in color of the teeth, sensitivity to sunlight or ultraviolet light (rash on the skin, or severe sunburns), vaginal infection, severe skin reactions, strong headaches, vision problems, lupus, ulcers or inflammation of the airways, lower blood pressure, joint or muscular pain, drowsiness, abnormalities in blood tests, jaundice, difficulty swallowing, swollen tongue, or tinnitus.

Doxycyline may cause increased sensitivity to sunlight. Avoid taking your child out into the sun and if you do, make sure he is properly protected. If the medication is given to treat syphilis, doctors need to continue monitoring the case even after the child no longer needs the medication. Tell your doctor if your child will be getting anesthesia for upcoming procedures (including dental work).

If your daughter is taking birth control pills while taking medication, she should use additional protection to avoid getting pregnant. Doxycyline reduces the effectiveness of birth control pills.
