Can I Use Susten SR 300 Tablets Vaginally After My IUI, Or Should I Replace Them With Susten 300 Capsules?

My gynecologist suggested me to take Susten SR 300 vaginally after my IUI procedure. Previously, I was pregnant with IUI and miscarried in 8 weeks but at that time doctor gave me Susten 300 capsule to take vaginally . Now I am confused whether I can use Susten SR 300 vaginally as it comes in the form of tablet instead of capsule. Would it be okay if I use it internally? If not can I replace it with Susten 300 capsules?
