Veozah vs Lynkuet: how the two non-hormonal hot flash pills compare

For years, women who couldn't or didn't want to take hormones had few good prescription options for hot flashes. Now there are two pills in a brand-new class, approved about two and a half years apart. They sound alike and work in similar ways, but they are not interchangeable. Here is what the FDA labels actually say.

Veozah vs Lynkuet at a glance

How they work

Both act on brain cells involved in temperature control, called KNDy neurons, by blocking neurokinin receptors on them. Veozah, the first drug of its kind, blocks the NK3 receptor. Lynkuet blocks NK3 and also NK1, which makes it the first dual neurokinin blocker. Neither contains hormones.

Veozah: the liver warning

In September 2024 the FDA warned about rare but serious liver injury in people taking Veozah, and in December 2024 it upgraded that to a boxed warning, its most prominent kind. The label now calls for liver blood tests before you start, monthly for the first three months, and then at months 6 and 9.

The FDA tells patients to stop Veozah right away and contact the prescriber if they notice signs of liver trouble: unusual tiredness, nausea or vomiting, unusual itching, light-colored stools, yellowing of the skin or eyes, dark urine, abdominal swelling, or pain in the upper right belly.

Veozah also can't be taken with medicines that block the CYP1A2 enzyme, such as the antidepressant fluvoxamine, because they raise Veozah levels in the blood. Bring your full medication list.

Lynkuet: drowsiness, liver tests and pregnancy

Lynkuet is taken at bedtime for a reason: sleepiness and related nervous system effects were more common than with placebo in trials. The label advises not driving or doing anything hazardous until you know how it affects you. Liver blood tests are needed before you start and again at 3 months, and you should stop it and call your clinician if you develop symptoms of liver injury.

Lynkuet must not be used in pregnancy. The label says to rule out pregnancy before starting and to use effective contraception during treatment and for 2 weeks after stopping. That matters more than it sounds: you can still get pregnant in perimenopause, until you have gone a full year without a period. Lynkuet is broken down by the CYP3A4 enzyme, so strong blockers of that enzyme and grapefruit should be avoided, and some other medicines change the dose or rule it out. It should also be used with caution in anyone with a history of seizures.

Which works better?

As of today, we found no head-to-head trial comparing them directly. One 2025 indirect analysis, which compared results across separate trials, concluded they had a similar effect on how often and how severely hot flashes happen. Indirect comparisons are useful but can't replace a direct trial.

In practice, the choice often comes down to your other medicines, your liver and kidney health, how you feel about frequent blood tests versus possible drowsiness, and what your insurance covers. Some clinicians are interested in whether Lynkuet's extra NK1 action helps with sleep, and some have flagged its large capsule size as a hassle for women who have trouble swallowing pills. Neither of those should decide it for you without a conversation.

How they compare with hormone therapy

The Menopause Society calls hormone therapy the most effective treatment for hot flashes, and for healthy women under 60 or within 10 years of menopause without contraindications, it concludes the benefits outweigh the risks. Hormone therapy also treats vaginal dryness and helps prevent bone loss. Veozah and Lynkuet are approved only for hot flashes and night sweats. The Menopause Society's 2023 nonhormone review recommended fezolinetant based on strong evidence; Lynkuet was approved after that review.

That makes these pills an important option for women who can't take estrogen or would rather not. Neither is currently FDA-approved specifically for hot flashes caused by breast cancer treatment. Bayer has asked the FDA to add that use for Lynkuet, and the FDA accepted the application for Priority Review in September 2026.

Questions to bring to your clinician

1. Given my liver, kidneys and medication list, is either one safe for me?
2. Who orders my liver tests, and how will I get the results?
3. If I am still having periods, what contraception do I need?
4. How will we know it is working, and when do we reassess?
5. How does this compare with hormone therapy for someone with my history?

Tracking how many hot flashes you have, and how much they disrupt sleep, makes this conversation far more productive. Our free Symptom Snapshot builds a one-page summary in three minutes, and our doctor visit playbook covers the rest. If night sweats are wrecking your sleep, see waking at 3am in perimenopause.

Questions

Is Lynkuet better than Veozah?

There is no head-to-head trial. One 2025 indirect analysis found similar effects on hot flash frequency and severity. They differ mainly in safety monitoring and side effects: Veozah has a boxed liver warning with more frequent liver tests, while Lynkuet can cause drowsiness and must not be used in pregnancy. Your clinician can help weigh them for your history.

Can I take Veozah or Lynkuet if I've had breast cancer?

Neither is currently FDA-approved specifically for hot flashes caused by breast cancer treatment. Bayer has applied to add that use for Lynkuet, and the FDA accepted the application for Priority Review in September 2026. Talk with your oncology team before starting any hot flash treatment.

How often do you need liver tests on Veozah?

According to the current label, before you start, monthly for the first three months, and then at months 6 and 9, plus any time you have symptoms of liver injury. Lynkuet requires liver tests before starting and at 3 months.
