Tivicay (dolutegravir sodium) Dosage and Side Effects
TIVICAY is a prescription oral tablet used for treatment of HIV (Human Immunodeficiency Virus) infection in adults and children aged 12 years and older who weigh at least 40 kg.
Warnings and Precautions
TIVICAY will not stop you from passing HIV to others through sexual contact or blood contamination. You should use appropriate precautions, such as using condoms when you have oral or penetrative sex, and not reusing or sharing needles.
BEFORE you use TIVICAY talk to your doctor or pharmacist if you:
- have liver problems, including hepatitis B or C
- are pregnant or planning to become pregnant; do not take TIVICAY without speaking with your doctor. Your doctor will consider the benefit to you and the risk to your baby when taking TIVICAY while pregnant. If you take TIVICAY while you are pregnant, talk to your doctor about enrolling in the Antiretroviral Pregnancy Registry.
- are breastfeeding or plan to breastfeed. Where possible, women who are HIV positive should not breast feed, because HIV infection can pass into breast milk and harm your baby.
- It is not known if TIVICAY can pass into breast milk and harm your baby. Talk to your doctor immediately, if you are breastfeeding, or thinking about breastfeeding. Do not breastfeed while taking TIVICAY.
- have any other medical condition
- are taking any other medications
The most common side effects of TIVICAY include:
- trouble sleeping (insomnia)
- feeling sick (nausea)
- lack of energy (fatigue)
Other side effects include, rash, itching (pruritus), being sick (vomiting), stomach pain (abdominal pain), stomach (abdominal) discomfort, intestinal gas (flatulence), dizziness, abnormal dreams, depression (feelings of deep sadness and unworthiness), and suicidal thoughts and behaviours (mainly in patients who have had depression or mental health problems before). If you have such feelings, talk to your doctor.
Side effects that may show up in blood tests include an increase in bilirubin (a substance produced by the liver), and/or an increase in the level of enzymes produced in the muscles (creatine phosphokinase, creatinine).
Changes in your immune system (Immune Reconstitution Inflammatory Syndrome) can happen when you start taking HIV medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time, or you could develop an autoimmune disease in which your immune system reacts against your own body (e.g. Graves' disease (which affects the thyroid gland), Guillain-Barré syndrome (which affects the nervous system) or polymyositis (which affects the muscles) and it may develop at any time, sometimes months later after the start of HIV therapy). Sometimes symptoms can be severe, so if you develop high temperature (fever), joint or muscle pain, redness, rash, swelling, or fatigue or any new symptoms contact your doctor immediately.
Changes in body fat have been seen in some patients taking antiretroviral therapy. These changes may include increased amounts of fat on the upper back and neck (“buffalo hump”), breasts, and around the trunk. Loss of fat from the legs, arms, and face may also happen. The cause and long-term health effects of these conditions are not known at this time.
