Abacavir can cause other serious side effects that may not be signs of an allergic reaction. Call your doctor at once if you have:

  • the first sign of any skin rash, no matter how mild;
  • signs of a new infection such as flu symptoms, chills, easy bruising or unusual bleeding, loss of appetite, mouth sores;
  • severe pain in your upper stomach spreading to your back;
  • itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes);
  • increased sweating, tremors in your hands, anxiety, feeling irritable, sleep problems (insomnia);
  • diarrhea, unexplained weight loss, menstrual changes, impotence, loss of interest in sex;
  • swelling in your neck or throat (enlarged thyroid);
  • weakness or prickly feeling in your fingers or toes;
  • problems with walking, breathing, speech, swallowing, or eye movement; or
  • severe lower back pain, loss of bladder or bowel control.

Less serious side effects may include:

  • strange dreams;
  • headache, ear pain;
  • cold symptoms such as stuffy nose, sneezing, sinus pain; or
  • changes in the shape or location of body fat (especially in your arms, legs, face, neck, breasts, and trunk).
