This represents an incidence of about 0.9% compared with an expected background rate of about 0.1% in infants born to women taking other antiretroviral medicines at the time of conception.<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<p>While this safety signal is being evaluated, the following measures are recommended:<span class=\"Apple-converted-space\">\u00a0<\/span><\/p>\n<ul>\n<li><strong>In women of child bearing potential (WOCBP) pregnancy testing should be performed and pregnancy should be excluded before initiation of treatment.<span class=\"Apple-converted-space\">\u00a0<\/span><\/strong><\/li>\n<li><strong>WOCBP who are taking dolutegravir should use effective contraception throughout treatment.<span class=\"Apple-converted-space\">\u00a0<\/span><\/strong><\/li>\n<li><strong>In WOCBP who are actively seeking to become pregnant, it is recommended to avoid dolutegravir.<span class=\"Apple-converted-space\">\u00a0<\/span><\/strong><\/li>\n<li><strong>In case a woman becomes pregnant while taking dolutegravir and the pregnancy is confirmed in the first trimester, it is recommended to switch to an alternative treatment unless there is no suitable alternative.<span class=\"Apple-converted-space\">\u00a0<\/span><\/strong><\/li>\n<\/ul>\n<p><b><i>Background\u00a0information<br \/>\n<\/i><\/b><\/p>\n<p>The issue has been identified from a preliminary unscheduled analysis of the ongoing Tsepamo study in Botswana.
