International prescribing information • Follow your local prescription and pack leaflet
What it is used for
The UK product treats depression and helps maintain improvement in people who respond. It is not an approved U.S. treatment.
Other uses need a separate evidence discussion. Sharing a norepinephrine target with another medicine does not mean equal benefit.
How it works
Reduces reuptake of norepinephrine, changing its availability between nerve cells. How this produces mood benefit is not fully known.
Dry mouth, constipation, and urinary difficulty can occur despite little direct muscarinic binding. Selective does not mean risk-free.
What to expect over time
EARLY DAYS
Dry mouth, sweating, dizziness, or sleep trouble may appear first. Tell your team if effects interfere with daily life.
OVER SEVERAL WEEKS
Improvement is not immediate. Review mood and daily function; do not increase the dose because one day feels worse.
KEEPING BENEFIT
Continue as prescribed after improvement. Review benefit and side effects regularly and make a plan before stopping.
Taking your medication
Take your prescribed dose twice daily, with or without food. Swallow with water; do not chew. The Edronax tablet can be halved.
Keep consistent times. If sleep is affected, ask about an earlier second dose; do not change the dose or schedule on your own.
Rise slowly and avoid driving until your response is known. Alcohol can impair safe functioning or worsen depression; discuss avoidance.
When to get help
Emergency care: seizure, fainting, severe allergic breathing trouble, or agitation/confusion with fever, sweating, and muscle jerks.
Call promptly for worsening mood, suicidal thoughts, marked agitation, or unusually high energy. Seek emergency help for immediate danger.
Get urgent care for inability to urinate, eye pain with sudden vision changes, severe palpitations, confusion, or new unsteadiness.
Early side effects
Insomnia, dizziness, dry mouth, constipation, nausea, and sweating are common. Restlessness, appetite loss, or a fast pulse can occur.
Other effects to discuss
Report urinary trouble, erection, or ejaculation problems, persistent dizziness, or blood-pressure changes. These deserve review.
What to keep track of
Track mood, sleep, pulse, blood pressure, bowel function, and urination. Your team may check electrolytes with diuretics, illness, or concerning symptoms. ECG and other tests depend on your medical risks. Do not assume a selective mechanism eliminates heart, urinary or serotonin-related risks.
Before you start
Discuss seizures, bipolar symptoms, self-harm risk, heart disease, blood-pressure problems, glaucoma, an enlarged prostate, or trouble urinating, and kidney/liver disease. List all medicines, supplements, and allergies. UK guidance does not recommend routine use in older adults or those under 18. Discuss pregnancy and breastfeeding.
Medicines & interactions
MAOIs / urgent treatments
Do not combine with an MAOI, including linezolid or methylene blue. A planned gap of at least two weeks after an antidepressant MAOI is needed, sometimes longer.
Drugs that raise reboxetine levels
Avoid interacting CYP3A4 inhibitors such as ketoconazole, erythromycin, nefazodone, or fluvoxamine. Ask before any new antibiotic or antifungal.
Drugs that lower levels
Carbamazepine, phenytoin, phenobarbital, rifampin, and St. John's wort can reduce exposure. Do not adjust your own dose to compensate.
Other serotonin-related medicines
Other antidepressants, lithium, buspirone, triptans, opioids, and tryptophan can add serotonin-syndrome risk. Check all combinations with your team.
Blood pressure / water tablets
Blood-pressure medicines can add standing dizziness; potassium-losing diuretics need review. Ergot medicines may raise blood pressure.
Everyday tips
Use a twice-daily reminder and bring your medication list to visits. Ask someone you trust to help notice new mood or behavior changes.
Try sugar-free gum, good dental care, appropriate fluids, fiber, and movement for mild dry mouth or constipation. Report persistent symptoms.
Report difficulty starting urination promptly. Do not add a bladder medicine yourself; inability to urinate is urgent, not a routine nuisance.
Keep early follow-ups and visits after dose changes. Suicidal thinking needs attention at any age; increased risk is documented under age 25.
Your questions, answered
What if I miss a dose?
The Edronax leaflet says to skip the missed dose and take the next at its normal time. Never double to catch up.
Can I stop once I feel better?
Agree on a stopping plan, often gradual. Headache, dizziness, nervousness, or nausea may follow stopping; depression can also return.
Why might my dose start lower?
Kidney or liver problems and tolerability can change the plan. Follow your own prescription, not the general adult dose in another leaflet.
Pregnancy or breastfeeding?
Discuss the benefits, risks, and alternatives promptly. Data are limited; low milk transfer does not prove infant safety. Do not stop abruptly.
Storage & safety
Keep away from children, at, or below 25°C and protected from moisture. Keep the bottle's drying cylinder inside; never swallow it. Suspected overdose needs immediate medical/poison-center advice, even without symptoms. In the U.S., call 1-800-222-1222; call emergency services for collapse, seizure, or breathing difficulty.
