Draft for review · Clinical content has not been revalidated for this website.
Your prescription determines the strength and schedule. Do not change doses on your own.
What it is used for
Treats schizophrenia in adults, including hallucinations and delusions.
The goal is less distress and better everyday functioning. It is not approved for children.
How it works
Xanomeline acts on muscarinic signals in the brain. It works differently from medicines that directly block dopamine receptors.
Trospium limits some effects elsewhere in the body. It does not prevent every side effect.
What to expect over time
FIRST DAYS
Your prescriber raises the dose in steps while checking tolerability.
OVER WEEKS
Track symptoms and daily life. Improvement is not always immediate.
ONGOING
Keep taking the prescribed dose even when you feel better; review changes together.
Taking your medication
Take one capsule twice daily: at least 1 hour before or 2 hours after a meal. Swallow it unopened.
Follow your written dose plan. Older adults may need slower changes and a lower maximum.
For a missed dose or several missed days, ask your pharmacist/prescriber. Do not double up.
When to get help
Emergency help: trouble breathing or face/throat swelling. Stop the medicine for this reaction. Inability to urinate also needs immediate care.
Urgent care: painful red eyes with halos or vision change; severe belly pain, swelling, or repeated vomiting.
Call promptly: yellow eyes/skin, dark urine, trouble peeing, a racing pulse, or new confusion. Do not simply wait these out.
Early side effects
Nausea, indigestion, constipation, vomiting, diarrhea, dizziness, and a faster pulse can occur. Tell your team if symptoms persist or interfere with eating or daily life.
Other effects to discuss
Movement and weight effects were relatively uncommon in short studies, but they are still worth checking. Report new movements, weight changes, dry mouth, or blurred vision.
What to keep track of
Your team checks liver tests and pulse before treatment and as needed afterward. Keep track of bowel movements, urination, alertness, and symptom changes; blood pressure and kidney health also matter.
Before you start
Tell your team about liver/kidney disease, gallstones, prostate, or bladder trouble, slow stomach emptying, severe constipation, glaucoma, ulcerative colitis, or myasthenia gravis. Some conditions make this medicine unsuitable. Discuss pregnancy, pregnancy plans, and breastfeeding before changing treatment.
Medicines & interactions
All medicines
Bring a full list, including vitamins, herbs, and nonprescription products. Some antidepressants and other medicines change Cobenfy levels or are affected by it.
Bladder, allergy & sleep aids
Some add dry mouth, constipation, or trouble urinating. Check before using these, including diphenhydramine or other sedating antihistamines.
Alcohol & sedatives
Ask before combining them. Avoid driving or machinery until you know how treatment affects alertness and vision.
Food timing
Food can change how the two ingredients are absorbed. Keep the meal window even if other medicines are taken with food; ask for a workable schedule.
Everyday tips
Use a written morning/evening dose-and-meal plan.
Tell your team early about bowel or bladder changes.
Track one or two goals, such as less distress or better sleep.
Include a trusted support person if you want help noticing changes.
Your questions, answered
Why are there two numbers?
They show the amounts of the two ingredients, not two separate prescriptions.
Can I open the capsule?
No. Do not open it or sprinkle the contents. Ask for advice if swallowing is difficult.
What if I feel better?
Keep the agreed plan. Discuss stopping or switching with your prescriber so symptoms are monitored.
What about pregnancy or nursing?
Human safety information is limited. Discuss benefits, risks, and the pregnancy exposure registry; do not stop on your own.
Storage & safety
Keep securely at room temperature, away from children; do not share. For overdose, call Poison Control at 1-800-222-1222 promptly. Call 911 for collapse, seizure, breathing trouble, or inability to wake.
