Information about Tivicay▼
What is it and what is it used for?
- In patients whose virus is not resistant to integrase inhibitors, the usual dose is one 50-mg tablet a day; however, when given with certain medicines that decrease the effectiveness of Tivicay the dose is increased to one 50 mg tablet twice a day.
- The dose is one 50-mg tablet twice a day in patients whose virus is known or suspected to be resistant to integrase inhibitors; in these patients, giving Tivicay with medicines that decrease its effectiveness should be avoided.

- Women who can become pregnant should use effective contraception while taking dolutegravir medicines.
What studies have been done?
- In the first of these, involving 822 patients, Tivicay once daily was compared with raltegravir (another integrase inhibitor), both given in combination with two other HIV medicines of a different class (known as nucleoside reverse transcriptase inhibitors or NRTIs): 88% (361 of 411 patients) given Tivicay and 85% (351 of 411) given raltegravir responded after 48 weeks of treatment.
- The second study involved 833 patients given either a combination of Tivicay with two NRTIs or a different three-drug combination (Atripla) that did not include an integrase inhibitor. The response rate at 48 weeks was 88% (364 of 414 patients) in those given Tivicay-based treatment compared with 81% (338 of 419 patients) in those given Atripla.
- The first of these involved 715 patients whose previous treatment had not included an integrase inhibitor and whose infection was therefore not expected to be resistant to this class of medicines. Patients were treated with a combination of HIV medicines that included either Tivicay or raltegravir. Response rate at 48 weeks was 71% in patients given treatment based on Tivicay, and 64% in those given treatment based on raltegravir.
- The second study in previously treated patients involved 183 patients with infection resistant to previous treatment that had involved an integrase inhibitor (i.e. their infection was resistant to several classes of medicine, including previous integrase inhibitors): adding Tivicay twice daily to other treatment resulted in a response rate of 69% after 24 weeks of therapy.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions (side effects) after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals or patients are asked to report any suspected adverse reactions via the Yellow Card Scheme at yellowcard.mhra.gov.uk or search for MHRA Yellow Card in the Google Play or Apple App Store.
