[|Human|] Hi there, I wanted to ask a question about the patch as a method of birth control. I started my period on May 5th, and applied the patch last friday (May 16th). Is it going to be affective in 7 days, even though I didn t apply it the day my period started, or the Sunday afterwards? I am worried because the Ortho Evra instructions only provide those two days as starting points.
[|AI|]  Hello, Thanks for trusting us with your health concern. Your current cycle may not be well protected since you started using the patch well after the last period. So, you need to use additional protection. Also, you have to continue using the three courses of the patch followed by a patch-free week. This means your cycle is rescheduled. Do not use grapefruit and grapefruit juice while using the patch as norelgestromin and ethanol estradiol have interactions. Avoid using skin creams, lotions etc., to the area of the skin where the patch is applied since this may lead to detachment of the patch. Hope this helps.
