Veozah Side Effects: What’s Common, What’s Serious, and When to Stop

What are the most common Veozah side effects?

In Veozah’s 52-week placebo-controlled study (Trial 3), the most common side effects were stomach pain (4.3%), diarrhea (3.9%), trouble sleeping (3.9%), back pain (3.0%), hot flashes (2.5%), and raised liver enzymes (2.3%) — each reported more often than with a placebo. “Common” doesn’t mean “always harmless,” though. Stomach pain is on this list AND on the liver-warning list, so it gets treated with extra care.

Below is The HRT Index Veozah Side-Effect Action Matrix.The percentages come straight from the label’s 52-week study (Trial 3, which included 609 women on Veozah 45 mg and 610 on placebo). We added the placebo column so you can see the difference between the two groups, and an action column so you know your next move.

Why we flagged stomach pain twice

Stomach pain was the single most common side effect in the study. It’s also on the FDA’s official list of “stop and seek care” liver-warning signs. That’s not a contradiction — it’s the exact reason you shouldn’t decide on your own that new belly pain is “nothing.” The page can’t tell the two apart by name alone, and neither can you. So new stomach pain gets the warning action, not a shrug.

Which Veozah side effects mean you should stop and get medical care?

Stop Veozah immediately and seek medical care — including a liver blood test — if you develop new fatigue, appetite loss, nausea, vomiting, itching, yellow skin or eyes (jaundice), pale stools, dark urine, or stomach pain. These are the label’s official signs of possible liver injury. Any one of them is enough. They are not “watch and wait a few days” symptoms.

Veozah can, in rare cases, cause serious liver injury. The FDA first warned about this on September 12, 2024, then on December 16, 2024 added a boxed warning — the most serious warning the FDA gives a medicine, printed in a black box at the top of the label.

Why “within 40 days” doesn’t mean you’re safe after day 40

You may read that the rare serious cases reported to the FDA happened within about 40 daysof starting Veozah. That’s true — and worth knowing. But it does not mean day 40 is a finish line. Keep watching for the warning signs the whole time you take it, and keep every scheduled blood test.

How rare is the serious kind?

The FDA describes serious liver injury as rare.We won’t put a hard percentage on it, because these are voluntary reports that come from an unknown number of users — you can’t calculate a reliable rate from them. What we can tell you is what the studies showed, which is the next section.

How can you tell a common Veozah side effect from a liver-warning symptom?

You often can’t tell by the symptom name alone — that’s the honest answer. Stomach pain is on both lists. Nausea and fatigue are warning signs even though they’re not on the “common side effects” table. So the safe rule is simple: match your symptom against the official warning list first, and when in doubt, stop and call.

The HRT Index overlap map (built from the current Trial 3 table and the label’s liver-warning list):

Raised liver enzymes sit in their own box — they’re a blood-test result, not something you feel.

Three things this map makes clear — and they’re the whole point:

1. Stomach pain is on both lists.So new belly pain never gets an automatic “that’s normal.” It gets the stop-and-seek-care action.
2. Nausea and fatigue are warning signs — even though they’re not on the common side-effects table. This surprises people. New nausea or new fatigue means stop and get care, not push through.
3. Feeling fine doesn’t mean your liver is fine.In the studies, women with raised liver enzymes were generally symptom-free. That single fact is why the blood tests aren’t optional.

How common are Veozah side effects, really?

In the 52-week study (Trial 3), the listed side effects showed up in 2.3% to 4.3% of women on Veozah — 0.9 to 2.2 percentage points above placebo. The serious liver injuries are rarer, and because they come from voluntary reports, there’s no reliable percentage for them — only that the FDA calls them rare.

Numbers calm nerves better than adjectives, so let’s put these in context. Take stomach pain, the most common one. It was reported in 4.3% of women on Veozah and 2.1% on placebo — an observed difference of 2.2 percentage points, or about 2 more reports per 100 women in this trial. Randomly splitting women into two groups lets us compare them fairly, but that subtraction still isn’t proof the drug caused every extra case, and it isn’t a prediction for you personally.

We’re also not going to say “double the risk.” Technically 4.3% versus 2.1% is roughly double — but “double” makes a small number sound bigger than it is. The observed difference is what matters, and it’s small.

What liver tests do you need on Veozah, and when?

Before you start Veozah, the label calls for a baseline liver blood panel — ALT, AST, alkaline phosphatase, and bilirubin (total and direct). After you start, you need blood tests monthly for the first 3 months, then again at month 6 and month 9, plus any time warning symptoms appear.

Think of it as a schedule, not a suggestion.

When Veozah should not be started

Your clinician won’t begin it if your baseline ALT or AST is already at least twice the normal limit, or your total bilirubin is at least twice the normal limit. Your clinician reads these values in context and checks for other possible causes — it’s not something to eyeball yourself.

When it should be stopped — the clinical thresholds

The label directs a clinician to stop Veozah if liver enzymes climb above five times the normal limit, or above three times the normal limit together with total bilirubin above twice the normal limit. If enzymes go above three times normal, the label calls for more frequent testing until they settle and a check for other causes. Your clinician reads the numbers and acts. Your job is to show up for the tests and report symptoms.

What if you miss a scheduled liver test?

Call your prescriber and reschedule it. Don’t assume the next one will cover it, and don’t decide on your own that feeling fine means you can skip it. Monitoring is designed to catch liver changes — including the silent kind — early.

Who should not take Veozah?

Veozah is contraindicated (a firm “no”) if you have known cirrhosis, severe kidney impairment or kidney failure, or if you take any CYP1A2-inhibitor medicine. It also shouldn’t be started if your baseline liver tests are already too high. Pregnancy is different — it’s not a contraindication, but there isn’t enough data to judge the risk.

What medicines interact with Veozah?

Veozah is a CYP1A2 substrate — your body clears it using an enzyme called CYP1A2. Any drug that blocks that enzyme makes Veozah levels rise, so the label says Veozah can’t be combined with weak, moderate, OR strong CYP1A2 inhibitors. The safe move is to have a pharmacist check your full list — not to rely on a short web list.

CYP1A2 is one of your liver’s cleanup crews. When inhibitor drugs slow it down, Veozah builds up higher than intended. That’s why this isn’t a “space them out” situation — it’s a “don’t combine” situation.

Why a short list is never enough on its own: drug lists change over time; the same drug has different brand and generic names; you might not realize an OTC product or supplement even counts; and the rule covers every CYP1A2 inhibitor, not just three famous ones.

And never stop another prescribed medicine on your own to make room for Veozah — let a clinician sort that out.

How long do Veozah side effects last?

The label doesn’t give one set timeline for how long side effects last, so be wary of any page that promises they’ll vanish in “a few days.” In everyday use, mild effects like diarrhea or back pain often ease over the first weeks. But warning signs are different — those need action now, not patience.

The label reports how often side effects happened, not how longthey lasted — and people differ. So here’s a better plan than guessing: write it down.A short log turns “I don’t feel right” into something your clinician can actually use.

Does Veozah cause weight gain, hair loss, headaches, nausea, or fatigue?

Weight gain, hair loss, and headaches are NOT listed among Veozah’s common side effects — but “not listed” isn’t the same as “impossible” for any one person. Nausea and fatigue are different: both are official liver-warning signs, so they get the stop-and-seek-care action, not a shrug.

Can you drink alcohol on Veozah?

The U.S. label does not set a “safe number of drinks” or name an alcohol interaction — so no honest page can hand you a limit. But because Veozah’s boxed safety concern is the liver, and alcohol can also affect the liver, the responsible answer is to ask your prescriber or pharmacist based on your own liver history and test results.

The absence of a stated limit is not the same as “alcohol is safe” — it just means the label doesn’t address it. Bring these questions to your clinician:

• Does my liver history change your advice?
• Should I skip alcohol until my early blood tests come back clear?
• Do any of my other medicines add liver risk?
• Which symptoms should send me in right away?

What should you do when a Veozah side effect starts?

Your next step depends on the symptom. Warning signs mean stop and get care right away. Ongoing but non-warning effects mean call your prescriber. Nobody should change, split, or restart Veozah based on a website, including this one.

1. Any warning sign?(Jaundice, dark urine, pale stools, nausea, vomiting, itching, unusual fatigue, appetite loss, stomach pain.) → Stop and seek medical care right away. Ask for a liver test.
2. Persistent or rough non-warning effect?(Insomnia that won’t quit, diarrhea wearing you down, back pain that’s severe, anything hurting your eating, sleep, or daily life.) → Call your prescriber.Don’t change the dose yourself.
3. Not sure which bucket you’re in?→ Write it down and, if there’s any doubt, treat it as a warning sign and call.
4. Started something new?→ Ask a pharmacist to screen it for CYP1A2 interactions.
5. Want to help future patients? → You can report a suspected side effect through FDA MedWatch (not a substitute for contacting your clinician).

What if the side effects aren’t worth it — or Veozah just isn’t right for you?

If you can’t tolerate Veozah, or a contraindication rules it out, you have good options — and the right one depends on your health history. A clinician can help tell a drug side effect apart from menopause itself, and talk through whether to stop or switch.

How to decide cleanly

• If reliable blood-test monitoring isn’t realistic, or you have a contraindication→ Veozah probably isn’t your best path, and that’s completely okay. An estradiol patch or pill (if you’re a candidate) doesn’t carry this liver-testing schedule — though it has a different risk profile and its own boxed warnings, so it’s a real conversation, not a free pass.
• If you can do the monitoring and want a non-hormonal option→ Veozah is a legitimate, FDA-approved choice worth discussing with your prescriber.

Your other options, briefly

• Systemic menopausal hormone therapy (estrogen) — for women who are candidates, usually paired with a progestogen if you still have your uterus. Different risk profile; no routine liver-testing requirement.
• Lynkuet (elinzanetant) — a newer FDA-approved non-hormonal pill (approved October 2025) that blocks two brain receptors (a dual NK1/NK3 antagonist), with its own label and risk profile. Fewer liver tests required.
• Brisdelle (low-dose paroxetine) — an FDA-approved non-hormonal option, plus other off-label approaches your clinician may raise.

What do real patients say about Veozah side effects?

Patient stories are useful for one thing: showing what women actually go through and worry about. They can’t tell you how often a side effect happens, whether Veozah caused it, or what you should do.

In menopause communities like Reddit’s r/Menopause and on drug-review sites, the questions that come up most are the same ones this page answers: Is this nausea normal or is it my liver? Should I stop, or wait? How long does the tiredness last? Can I take half a tablet?

What we want you to take from that: “tired and nauseous” maps directly onto the liver-warning list. The responsible response to those posts isn’t “that’s normal, push through.” It’s: new nausea or fatigue is a reason to stop and call, not to wait. Patient voices point you toward caution here, not away from it.
