How is Skyla different from Mirena?

<p>Skyla and Mirena are pretty similar, but Skyla lasts for up to 3 years while Mirena lasts for up to 8 years. Also, Skyla is slightly smaller than Mirena and was FDA-approved for women who&rsquo;ve never had a child, though both IUDs are totally safe for most women to use, regardless of their parental status.</p>
