Estradiol — pill, patch, gel, or spray — can be taken any time of day; pick a time you will remember and stay consistent. Oral micronized progesterone (Prometrium and generics) should always be taken at bedtime. It is metabolized to allopregnanolone, which acts on GABA-A receptors and causes mild sedation — taken at night this improves sleep; taken in the morning it causes daytime drowsiness. Vaginal estrogen is typically used at bedtime. Testosterone cream is applied in the morning to mirror the natural diurnal pattern.
