HelloPharmacist Editorial Team Bottom Line
Lynkuet is a non-hormonal once-daily capsule that helps reduce moderate to severe hot flashes caused by menopause by targeting brain signals that trigger them. It is not safe during pregnancy and requires liver monitoring before and during use. Take it at bedtime, be aware it can cause drowsiness, and avoid grapefruit and several common medications — ask your pharmacist to check your full medication list.

📖 Elinzanetant: Patient Information Guide

A plain-language walkthrough of Elinzanetant — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for

Elinzanetant is used to treat vasomotor symptoms (hot flashes and night sweats) caused by menopause.

  • Lynkuet capsules (oral): Approved for the treatment of moderate to severe vasomotor symptoms due to menopause
⚙️How it works

Elinzanetant works by blocking two receptors in the brain — neurokinin 1 (NK1) and neurokinin 3 (NK3). These receptors sit on a group of nerve cells that help regulate body temperature. During menopause, changing hormone levels can over-activate these nerve cells, setting off hot flashes. By blocking the NK1 and NK3 signals — carried by proteins called Substance P and Neurokinin B — elinzanetant helps quiet the misfiring temperature-control circuit and reduce the frequency and intensity of hot flashes.

💊How it's taken

Lynkuet comes as an oral capsule and is taken once a day at bedtime, at roughly the same time each night. It can be taken with or without food, but always swallow the capsules whole with water — do not cut, crush, or chew them.

  • If you miss a bedtime dose, skip it and take your next dose the following night as scheduled
  • Never take two doses in one day to make up for a missed one
  • If you are also taking a moderate CYP3A4 inhibitor, your prescriber may lower your Lynkuet dose — follow their specific instructions
🤒Side effects — in detail

The most commonly reported side effects with Lynkuet include:

  • Headache
  • Fatigue or tiredness
  • Dizziness (including balance problems and vertigo)
  • Drowsiness (somnolence)
  • Nausea
  • Abdominal pain
  • Diarrhea
  • Rash
  • Muscle spasms

More serious reactions include liver enzyme elevations and seizure — get medical help right away if you notice signs of liver injury (jaundice, dark urine, severe stomach pain) or if you have a seizure.

⚠️Warnings & precautions
  • Drowsiness and impairment: About 12% of people taking Lynkuet in trials experienced nervous system effects like drowsiness, dizziness, or lightheadedness. Do not drive or use heavy machinery until you know how the medicine affects you.
  • Liver injury risk: Liver enzyme elevations have been reported. Blood tests are required before you start Lynkuet and should be repeated 3 months into treatment. Stop immediately and seek care if you develop jaundice, dark urine, pale stools, unusual fatigue, or stomach pain.
  • Seizure risk: Seizures have been reported. Use Lynkuet cautiously if you have a history of seizures or conditions that lower your seizure threshold.
  • Pregnancy: Lynkuet must not be used during pregnancy — animal studies show it can cause pregnancy loss or stillbirth. Use effective contraception during treatment and for 2 weeks after stopping.
🔀What it interacts with

Elinzanetant is primarily broken down by a liver enzyme called CYP3A4, so drugs and foods that affect this enzyme can significantly change how much elinzanetant is in your body.

  • Strong CYP3A4 inhibitors (e.g., certain antifungals, some antibiotics, some HIV medications): Avoid — these raise elinzanetant levels and increase the chance of side effects
  • Grapefruit and grapefruit juice: Avoid — acts like a strong CYP3A4 inhibitor and can raise elinzanetant levels
  • Moderate CYP3A4 inhibitors: Can be used with a lower Lynkuet dose — your prescriber will adjust your regimen
  • Strong or moderate CYP3A4 inducers (e.g., certain anti-seizure or tuberculosis medications): Avoid — these lower elinzanetant levels and may make Lynkuet ineffective
  • CYP3A4 substrate medications: Lynkuet mildly inhibits CYP3A4, so it can raise the blood levels of other drugs processed by this enzyme — your prescriber or pharmacist should review your full medication list

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it
  • Pregnancy: Lynkuet is contraindicated (must not be used) during pregnancy due to risk of pregnancy loss or stillbirth — a negative pregnancy test is required before starting
  • Reproductive-age women: Use effective contraception during treatment and for 2 weeks after stopping; stop and tell your doctor immediately if you become pregnant
  • Breastfeeding: There are no human data on elinzanetant in breast milk; the drug is present in animal milk — discuss the risks with your doctor before breastfeeding
  • Liver impairment: Not recommended for people with moderate to severe hepatic (liver) impairment; liver blood tests are required before starting
  • End-stage kidney disease: Not recommended
  • History of seizures: Use with extra caution; inform your doctor
  • Children: Not approved for use in pediatric patients — safety and efficacy have not been established
  • Adults over 65: Limited data available; discuss any concerns with your prescriber
🚑If you take too much

There is no specific antidote for a Lynkuet overdose. If too much is taken, the person should be closely monitored and treated based on any symptoms that develop. If you suspect an overdose, seek emergency medical attention right away.

📡Pharmacodynamics — effects in the body

In clinical studies, single doses of elinzanetant at up to five times the maximum recommended dose did not cause a clinically meaningful prolongation of the QTc interval — a heart-rhythm measurement tracked in drug safety studies. However, the effect on heart rhythm when elinzanetant is combined with strong CYP3A4 inhibitor medications has not been fully studied, which is one reason that combination is to be avoided.

🔬Pharmacokinetics — how your body processes it

After daily dosing, elinzanetant reaches steady-state blood levels (a stable plateau in the body) within 5 to 14 days. Drug levels in the blood increase at a rate greater than proportional to the dose — meaning doubling the dose raises blood levels by more than double — so staying at the prescribed dose is important. Elinzanetant is primarily broken down by the CYP3A4 enzyme system in the liver, which is why drugs and foods that affect CYP3A4 can significantly change how much elinzanetant is active in the body.

📦How to store it

Store at 20°C to 25°C (68°F to 77°F) with excursions permitted from 15°C to 30°C (59°F to 86°F) . Store the remaining capsule in the original blister card in the carton until the next dose.

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Elinzanetant — the kind of thing our pharmacy team would talk through with you at the counter.

What exactly does Lynkuet do for hot flashes?
Lynkuet works differently from hormone therapy. Instead of replacing estrogen, it blocks specific receptors in your brain — called NK1 and NK3 — that are involved in triggering hot flashes and night sweats. By quieting those signals, it helps your body's temperature-control system work more calmly. It's taken once a day at bedtime, and it typically takes days to weeks to build up to a steady level in your body.
Can I take Lynkuet if I'm still having periods or could get pregnant?
No — Lynkuet must not be used during pregnancy. Animal studies show it can cause pregnancy loss or stillbirth. Before you start, your doctor will confirm you're not pregnant. If you're of reproductive age and could become pregnant, you'll need to use effective birth control the whole time you're on it and for 2 weeks after your last dose. If you do become pregnant while taking it, stop the medicine right away and call your doctor.
Will Lynkuet make me drowsy during the day?
It can. In clinical trials, about 12% of people taking Lynkuet had nervous system effects like drowsiness, dizziness, or lightheadedness, compared to about 4% on placebo. Taking it at bedtime helps reduce daytime sleepiness. Until you know how it affects you, be cautious about driving or doing anything that needs your full attention and steady balance.
I've heard this medicine can affect the liver — should I be worried?
It's worth being aware of, though serious liver problems were uncommon in trials. Your doctor is required to check your liver with blood tests before you start Lynkuet, and again at 3 months. Watch for warning signs like yellowing of your skin or eyes, very dark urine, pale stools, unexplained fatigue, or stomach pain. If any of those happen, stop Lynkuet immediately and get medical attention. Don't start it at all if your liver tests were already elevated before you began.
Are there any medicines or foods I need to avoid while taking Lynkuet?
Yes, a few important ones. Avoid grapefruit and grapefruit juice — they can raise the level of Lynkuet in your blood. Strong CYP3A4 inhibitors (a category that includes some antifungals, certain antibiotics, and some HIV medications) also need to be avoided for the same reason. Certain other drugs called CYP3A4 inducers — like some seizure medications — can make Lynkuet less effective and should also be avoided. Your pharmacist can check your full medication list for any conflicts.
Can I cut or crush the capsules if I have trouble swallowing them?
No — you need to swallow Lynkuet capsules whole with water. Do not cut, crush, or chew them. Take them at bedtime with or without food. If swallowing capsules is a real problem for you, talk to your prescriber — but do not alter the capsules on your own.
Is Elinzanetant available over the counter?
Elinzanetant is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Elinzanetant first available?
Elinzanetant has been available in the United States since at least 2025, based on FDA approval history (Drugs@FDA) and product marketing records.
