HRT Dosage: The Real Numbers by Patch, Pill, Gel, and Progesterone

The HRT dosage chart: estrogen by route, plus progesterone

"HRT dosage" isn't one number the way a single-molecule drug's dosing schedule is. Estrogen comes in at least four delivery methods — patch, gel, pill, and spray — and each has its own FDA-approved dose range. Progesterone, when you need it, is dosed differently depending on whether your regimen is cyclic or continuous. Here's the at-a-glance version; the brand-specific detail follows below.

This page is about the numbers themselves — what's typical, what the range looks like, and how it gets adjusted. For the separate question of whether hormone therapy is safe or right for you in the first place, hormone therapy in perimenopause covers the candidacy and risk conversation in full.

Estrogen dosing by delivery method — patch, gel, pill, and spray

The route matters as much as the milligram number, because the same dose printed on two different products doesn't behave the same way once it's in your body. A patch or gel delivers estradiol straight into your bloodstream through skin; a tablet passes through your liver first, which is one reason oral and transdermal numbers aren't directly comparable to each other.

Among the patches, Vivelle-Dot, Alora, and Minivelle all come in several graduated strengths, which lets a prescriber move you up in smaller increments than a two-strength product would allow. Climara is the outlier in this group — it's changed once a week instead of twice, which some women prefer simply because it's less to remember.

There's also a vaginal ring version of systemic estrogen, Femring, which is a different device from the low-dose local rings used only for vaginal dryness. Femring starts at 0.05 mg/day and is changed every three months rather than daily or weekly.

One more distinction worth knowing before you compare numbers across providers: not every estrogen patch or cream on the market is one of the FDA-approved brands above. Some telehealth providers dispense compounded formulations instead, made at a licensed pharmacy rather than manufactured to a fixed FDA-set strength. HRT patches: what's legit and what's a scam covers that distinction, along with placement mechanics, in more depth.

Progesterone dosing: cyclic vs. continuous, and why it's paired with estrogen at all

Progesterone isn't there to relieve hot flashes — estrogen does that work. Its job, when you're also taking estrogen and still have a uterus, is to protect the uterine lining from the overgrowth that estrogen alone can cause over time. Women who've had a hysterectomy typically don't need progesterone at all and are prescribed estrogen alone.

The two regimens produce different bleeding patterns, which is often the deciding factor for which one you're prescribed. Cyclic dosing tends to produce a predictable, period-like withdrawal bleed each month — a reasonable trade-off for a woman still in perimenopause whose body already expects a monthly rhythm. Continuous dosing aims for no scheduled bleeding at all, though some spotting in the first few months is common while your body adjusts.

How titration actually works — why nobody gets "the" dose on day one

Contrast this with a drug like semaglutide, where the FDA prints out a fixed, week-by-week escalation schedule that applies to nearly everyone. HRT doesn't work that way. There's no printed ladder that says week four moves to this dose and week eight moves to the next — because the right dose depends on your starting symptom severity, your medical history, your chosen route, and how your body responds, none of which a printed schedule can account for in advance.

In practice, most women notice some initial change within four to eight weeks of starting a new dose — sleep evening out, hot flashes softening — while a fuller picture of whether the dose is actually enough tends to take closer to three months to become clear. That's the general window prescribers use before deciding whether to hold, raise, or adjust the formulation altogether. This is symptom-based dosing you work out with a licensed prescriber over that follow-up window, not a number you land on once and never revisit.

Is there a real "HRT dose calculator"?

Not in the way a calorie or BMI calculator works. A real dose depends on variables no formula can weigh on its own — your symptom pattern, your personal and family health history, which delivery route you and your prescriber choose, and how your body actually responds once you start. A quiz can point you toward a starting conversation, which is useful, but the number that ends up on your prescription comes from a licensed prescriber reviewing your specific situation, not a plugged-in equation.

What happens if you miss a dose of HRT

The answer depends on which form you're using, since a skipped patch behaves differently in your body than a skipped tablet.

Missed patch

Apply the patch as soon as you remember. If it's already close to your next scheduled change day, skip the missed one and apply your next patch on the regular schedule instead. Never wear two patches at once to make up for lost time.

Missed oral tablet — estrogen or progesterone

Take it as soon as you remember that day. If it's nearly time for your next scheduled tablet, skip the missed one and continue your regular schedule from there. Don't double up the next dose to compensate.

Missed gel or spray application

Apply it as soon as you remember, on the same day if possible. If you don't catch it until the next day's application is nearly due, skip the missed one rather than applying two doses close together.

Missed progesterone specifically

A single missed night is generally handled the same way as any other tablet — take it when you remember, skip it if it's nearly time for the next one. If you miss several days in a row during a cyclic 12-day course, call your prescriber rather than trying to reconstruct the schedule yourself, since the day count is what protects the uterine lining.

Signs your dose might be wrong

Both directions show up in fairly recognizable ways, which is exactly what your prescriber is listening for at a follow-up visit.

Signs your estrogen dose may be too high

• Breast tenderness that's new or more pronounced than usual
• Bloating or fluid retention that wasn't there before starting
• Breakthrough bleeding outside of what your regimen is designed to produce
• Headaches or mood swings that track with when you take your dose

Signs your estrogen dose may be too low

• Hot flashes or night sweats that haven't meaningfully improved after several weeks
• Sleep still fragmented by temperature swings
• Vaginal dryness that hasn't responded
• No noticeable change at all since starting — a real signal worth reporting rather than waiting out

Where dosing actually gets set

A prescriber reviews your symptoms and history, picks a starting dose and route, and then adjusts based on how you respond over the following weeks.
