4. Serious Skin Reactions

Rarely, severe skin reactions may occur, even weeks after you start using this medicine. Be aware of a rash that appears along with a fever or chills. These rashes may turn red or purple, then blister and the skin may start to peel. Also, seek medical advice immediately if you notice swelling of the face, lips, or a rash on the neck or armpits.

5. Be especially careful during pregnancy

If you are pregnant, be sure to talk to your doctor about this medication.

  • Taking this medicine after 20 weeks of pregnancy can cause serious birth defects in the baby.
  • It is not recommended to take this medicine after 30 weeks .
