Gepirone
Exxua
An extended-release antidepressant for adults. Heart checks are part of the treatment plan.
Draft for review · Clinical content has not been revalidated for this website.
Diagram: M means the 1-PP metabolite. Its alpha2 action is preclinical; a separate benefit is uncertain.
What it is used for
Exxua is approved to treat major depressive disorder in adults. It is not approved for children or bipolar depression. Ask what changes to watch for in daily life.
It is not interchangeable with buspirone, and a similar receptor action does not establish an anxiety indication. Your prescription should have a clear treatment goal.
How it works
Gepirone acts at a serotonin receptor called 5-HT1A. This activity is thought to help depression, although the full explanation for its benefit is not known.
It is not an SSRI. Even so, combining it with other medicines that affect serotonin can cause a dangerous reaction. Check new medicines and supplements first.
What to expect over time
BEFORE STARTING
An ECG checks heart rhythm. Your team will review medicines, health history, and blood salts such as potassium and magnesium.
EARLY DAYS
Dizziness or nausea may appear before benefit. Increases depend on tolerability and heart checks; never raise the dose yourself.
OVER WEEKS
Mood and daily function may improve gradually. Keep follow-up, and report worsening symptoms without waiting for the next visit.
Taking your medication
Take your prescribed dose once daily with food, at about the same time. Swallow the extended-release tablet whole; do not split, crush, chew, or dissolve it.
Use the strength on your prescription. Older age, kidney or liver problems and interacting medicines may limit the dose. Do not copy someone else's schedule.
Keep refills and follow-up on track. Rise slowly if dizzy, and do not drive or use machinery while impaired. Ask before adding a sleep or nausea medicine.
When to get help
Urgent heart assessment: fainting, marked lightheadedness, or a fast or irregular heartbeat. Collapse, chest pain, or severe symptoms: call 911.
Emergency care: fever with confusion, agitation, sweating, and stiff or twitching muscles; seizure, trouble breathing, or swelling of the face or throat.
Call promptly: suicidal thoughts, sudden mood worsening, agitation, or little sleep with unusual energy. Immediate danger: 911; U.S. crisis support: 988.
Early side effects
Dizziness, nausea, headache, insomnia, stomach pain, and indigestion may occur. Discuss persistent effects; a slower prescribed increase may help.
Other effects to discuss
Dry mouth, bowel changes, tiredness, sweating, appetite, or weight changes may occur. Sexual effects are possible; tell your team about changes.
What to keep track of
Keep ECG appointments before starting, during dose increases, and periodically afterward. Blood-salt checks depend on your risks and medicines; report prolonged vomiting or diarrhea. Review mood, sleep, function, and side effects, especially after changes. Mood checks matter at every age, particularly through age 24.
Before you start
Tell your team about fainting, heart rhythm problems, a personal or family history of long QT, kidney or liver disease, low potassium or magnesium, bipolar symptoms, pregnancy or breastfeeding. Some heart-rhythm findings, congenital long QT, and severe liver disease rule out this medicine. Bring a full list of prescriptions, nonprescription products, and supplements before starting or changing treatment.
Medicines & interactions
MAOIs, linezolid & IV methylene blue
Do not combine. At least 14 days are needed between an antidepressant MAOI and gepirone in either direction. Tell an urgent-care team you take gepirone.
Medicines that slow its breakdown
Strong CYP3A4 inhibitors cannot be combined. Moderate inhibitors require a prescribed dose change. Ask a pharmacist to check the combination; never cut an ER tablet to reduce the dose.
Medicines that speed its breakdown
Strong CYP3A4 inducers should be avoided because they can greatly lower exposure. Review seizure medicines, antibiotics, and herbal products before any change.
Other serotonin medicines
Other antidepressants, triptans, some opioids, and St. John's wort can add serotonin-syndrome risk. Check all pain, cough, migraine, and mood products with your team.
Heart-rhythm and fluid-balance medicines
Some medicines add heart-rhythm risk and require more ECGs. Water pills and steroid medicines can affect potassium or magnesium. Do not stop prescribed medicines yourself.
Everyday tips
Link your daily dose to a regular meal and use a reminder.
Keep a short record of mood, sleep, and troublesome effects.
Tell all clinicians and pharmacists that you take gepirone.
Use therapy and everyday supports alongside your prescription.
Your questions, answered
What if I miss a dose?
Take it when remembered unless it is time for the next dose; then skip it. Never take two doses together to catch up.
Can I stop when I feel better?
Make a plan with your prescriber. Stopping can bring symptoms back, and withdrawal symptoms may occur. There is no single label taper schedule; do not cut ER tablets.
Why not increase while I am still depressed?
Your ECG, other medicines, and side effects may limit increases. More is not automatically better. Discuss persistent symptoms rather than adjusting the dose yourself.
What about pregnancy or breastfeeding?
Discuss benefits and risks; do not stop on your own. Data are limited; late exposure may affect newborns. If breastfeeding, ask about checking the baby's alertness, feeding, and weight.
Storage & safety
Keep at room temperature in a dry place, securely away from children and pets. Never share; ask about pharmacy take-back. For overdose, call Poison Help at 1-800-222-1222 promptly. Collapse, seizure, breathing difficulty, or inability to wake: call 911.
