How does this medication work? What will it do for me?
Dolutegravir belongs to the class of medications called human immunodeficiency virus (HIV) integrase strand transfer inhibitors (INSTIs). It is used in combination with other medications to treat HIV infection for adults and children at least 6 years of age who weigh at least 15 kg and have not taken other INSTIs. Dolutegravir works by blocking an enzyme called integrase that is necessary for the HIV virus to reproduce. In doing so, it reduces the amount of HIV in the blood.
This medication does not cure AIDS and does not reduce the risk of passing HIV to others through sexual contact or blood contamination.

HEALTH CANADA ADVISORY
June 7, 2018
Health Canada has issued new restrictions concerning the use of dolutegravir. To read the full Health Canada Advisory, visit Health Canada's web site at www.hc-sc.gc.ca.
Hepatitis: Dolutegravir may cause liver function to worsen, particularly for people who also have hepatitis B or hepatitis C. If you have hepatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of liver problems (e.g., abdominal pain, persistent vomiting, feeling unwell, fever, itching, yellowing of the skin and eyes, dark urine), contact your doctor immediately.
Immune reconstitution syndrome: This medication may cause immune reconstitution syndrome, where signs and symptoms of inflammation from previous infections appear. These symptoms occur soon after starting anti-HIV medication and can vary. They are thought to occur as a result of the immune system improving and being able to fight infections that have been present without symptoms (such as pneumonia, herpes, or tuberculosis). Report any new symptoms to your doctor as soon as possible.
Kidney function: Kidney disease or reduced kidney function may affect how this medication works. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Stopping the medication: If you stop taking this medication, your HIV infection could get worse. Take the medication exactly as prescribed by your doctor, and do not stop taking the medication without checking with your doctor first.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if dolutegravir passes into breast milk. Women who have HIV infection are cautioned against breast-feeding because this increases the risk of passing HIV to a baby who does not have the infection.
Children: The safety and effectiveness of using this medication have not been established for children less than 6 years of age or who weigh less than 15 kg.
