<p><strong>Paediatric use</strong>: &nbsp;Efavirenz has not been studied in pediatric patients below 3 years of age or who weigh less than 10 kg.<br />
<br />
<strong>Women taking hormone-based birth control:&nbsp;</strong>Women should not rely only on hormone-based birth control, such as pills, injections, or implants, because Efavirenz may make these contraceptives ineffective.</p>
