Warnings and precautions

Take special care with ADCO-LAMIVUDINE 300 mg TABLETS:

• If you are pregnant or breastfeeding.
• If you have, or previously have had, a hepatitis B infection of the liver. ADCO-LAMIVUDINE 300 mg TABLETS may make the infection worse.
• If you develop stomach pain, nausea or vomiting. Check with your doctor, as these could be signs of an inflamed pancreas.
• It may result in a condition called lactic acidosis. If you are feeling unwell, consult your doctor.
• Liver disease has been known to occur.
• If you have kidney disease.
• If you have lipodystrophy (a problem with the way your body uses and stores fat). This condition is characterised by being overweight (obesity), build-up of fat on the back of the neck between the shoulders (buffalo hump), loss of fat under the skin (making the face look thin), breast enlargement and high levels of fat and glucose (sugar) in the blood. If you have any of these signs, you should be thoroughly examined by your doctor.
• If you have advanced HIV infection, your immune system is weak, and you are more likely to develop serious infections (opportunistic infections). Such infections may have been “silent” and not detected by the weakened immune system before treatment was started. After starting treatment, the immune system becomes stronger, and may attack the infections, which can cause symptoms of infection or inflammation. Symptoms usually include fever, plus some of the following: headache, stomach ache or difficulty breathing.
• In rare cases, as your immune system becomes stronger, it can also attack healthy body tissue (autoimmune disorders). The symptoms of autoimmune disorders may develop many months after you start taking medicine to treat your HIV infection.
• If you notice any of these symptoms of osteonecrosis (where parts of the bone tissue die, because of reduced blood supply to the bone): joint aches and pain, joint stiffness or difficulty in movement, tell your doctor.
