[165] [166] [163] [164] In one study, which administered a mean total dosage of sublingual estradiol of 4.8 mg/day, estradiol levels remained elevated at about 130 pg/mL on average in the morning before the first dose of the day. [165] Oral micronized estradiol valerate tablets can be taken sublingually as well.
