Warnings and precautions
Consult your doctor or pharmacist before starting to take this medicine.
This medicine may affect your kidneys. Before starting treatment, your doctor may ask you to have blood tests to check your kidney function. Your doctor may also ask you to have blood tests during treatment to monitor your kidneys.
This medicine is not normally taken with other medications that can harm your kidneys (see Taking Efavirenz/Emtricitabine/Tenofovir disoproxil Macleods with other medications). If this is unavoidable, your doctor will monitor your kidney function once a week.
If you have a hepatitis B infection, your doctor will carefully consider the best treatment plan for you. Tenofovir disoproxil and emtricitabine, two of the active ingredients in this medicine, show some activity against the hepatitis B virus, although emtricitabine is not authorized for the treatment of hepatitis B infection. Your hepatitis symptoms may worsen after stopping this medicine. Your doctor may perform blood tests at regular intervals to monitor your liver (see section 3, If you stop treatment with Efavirenz/Emtricitabine/Tenofovir disoproxil Macleods).
In addition to opportunistic infections, autoimmune disorders (a condition that occurs when the immune system attacks healthy body tissue) may also appear after you have started taking medications for the treatment of your HIV infection. Autoimmune disorders may appear many months after starting treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, weakness that starts in the hands and feet and moves up towards the trunk of the body, palpitations, tremors, or hyperactivity, inform your doctor immediately to receive the necessary treatment.
Bone problems (which manifest as persistent or worsening bone pain and sometimes end in fractures) due to damage to the renal tubule cells (see section 4, Possible side effects) may also occur. Inform your doctor if you have bone pain or fractures.
Tenofovir disoproxil may also cause bone mass loss. The most pronounced bone loss was observed in clinical studies when patients were treated with tenofovir disoproxil in combination with a boosted protease inhibitor.
In general, the effects of tenofovir disoproxil on long-term bone health and the future risk of fractures in adult and pediatric patients are unclear.
Inform your doctor if you know you have osteoporosis. Patients with osteoporosis have a higher risk of suffering fractures.

You may need blood tests to check liver function in the four months following treatment discontinuation. In some patients with advanced liver disease or cirrhosis, it is not recommended to stop treatment since this can cause worsening of hepatitis, which can be life-threatening.
→ Talk to your doctor immediately about new or unusual symptoms after stopping your treatment, particularly symptoms that you associate with hepatitis B virus infection.
