Paroxetine
Paxil / Paxil CR / Brisdelle
An SSRI used for depression and several anxiety conditions. The exact product matters, and stopping needs a careful plan.
Draft for review · Clinical content has not been revalidated for this website.
Paxil and Paxil CR have different doses and uses • Brisdelle 7.5 mg is for menopausal hot flashes, not depression
What it is used for
Paxil treats adult depression, panic disorder, social anxiety, generalized anxiety, OCD, and PTSD. Ask which symptom you are targeting.
Paxil CR treats depression, panic, social anxiety, and PMDD. Brisdelle treats menopausal hot flashes. These products are not interchangeable.
How it works
Slows serotonin reuptake between nerve cells. Mood and anxiety benefit builds over time; it is not simply correcting a proven deficiency.
Other actions may contribute to dry mouth, constipation, or sleepiness. The diagram does not prove a separate benefit from every target.
What to expect over time
EARLY DAYS
Nausea, sleepiness, or restlessness may precede improvement. Report troublesome effects rather than waiting them out.
OVER SEVERAL WEEKS
Mood and anxiety may improve gradually; some symptoms take longer. Keep follow-ups and agree on goals for the trial.
WHEN CHANGING DOSES
Track mood, sleep, and withdrawal symptoms. Do not rush a taper or assume a missed dose is harmless.
Taking your medication
Follow your prescription. Paxil and Paxil CR labels use morning dosing; Brisdelle is taken at bedtime. Ask before changing timing.
Take with or without food. Swallow CR tablets whole. PMDD schedules can differ; follow the specific days your prescriber gives you.
Avoid alcohol. Do not drive until effects are clear. Keep a refill plan: abrupt stopping or repeated misses can cause withdrawal.
When to get help
Get emergency care for fever with confusion or stiff/twitching muscles, seizure, fainting, severe allergy, or major bleeding.
Report new suicidal thoughts, marked agitation, or unusually high energy with little sleep promptly. Call 911 for immediate danger.
Get urgent advice for black stools, severe headache with confusion/weakness, or eye pain with vision changes; do not wait for a visit.
Early side effects
Nausea, bowel changes, dry mouth, sweating, dizziness, sleepiness, or insomnia can occur. Report effects that worsen or interfere with daily life.
Other effects to discuss
Sexual difficulties and weight gain can occur. Emotional flatness deserves a review, not an automatic assumption that your dose is too high.
What to keep track of
Review mood, sleep, weight, sexual function, and side effects, especially early and after dose changes. Sodium testing depends on symptoms and risk, including older age or water pills. Most people do not need routine drug levels. Warfarin users may need closer INR checks when treatment changes.
Before you start
Share all medicines and allergies, bipolar, or suicidal symptoms, seizures, glaucoma, bleeding, low sodium, bone problems, and kidney/liver or heart disease. Discuss pregnancy, breastfeeding, and fertility concerns. Do not add another paroxetine product. Ask before starting any new over-the-counter medicine or supplement.
Medicines & interactions
MAOIs / prohibited combinations
Do not combine with MAOIs; allow at least 14 days either way. Pimozide and thioridazine are contraindicated. Linezolid and IV methylene blue need urgent specialist review.
Tamoxifen
Paroxetine can reduce its active metabolite. Ask both prescribers about an alternative antidepressant; do not stop cancer treatment yourself.
Serotonin-raising products
Check other antidepressants, tramadol, triptans, lithium, buspirone, stimulants, St. John's wort and dextromethorphan cough products before use.
Bleeding / other medicine levels
Aspirin, ibuprofen, naproxen, and blood thinners increase bleeding risk. Paroxetine changes many drug levels; codeine or tramadol pain relief may decrease.
Alcohol / sedating medicines
Avoid alcohol. Sleep, allergy, anxiety, and opioid medicines may worsen impairment. Ask your pharmacist to review the full list, including water pills.
Everyday tips
Use reminders and arrange refills early. Ask for help with missed doses rather than skipping, doubling, or changing the schedule yourself.
Report worsening mood at any age. The antidepressant boxed warning includes increased risk through age 24, especially early or after changes.
Discuss sexual changes or weight concerns openly; treatment can be adjusted. Do not stop on your own or assume every symptom is from the drug.
Keep a current medicine list. Tell your care team promptly if pregnancy occurs; urgent safety problems should not wait for routine follow-up.
Your questions, answered
What if I miss a dose?
Take it when remembered unless the next dose is nearly due; then skip it. Never double. Repeated misses can cause dizziness, shocks, or flu-like feelings.
Can I stop once I feel better?
Arrange a gradual taper, sometimes over months with smaller reductions near the end. Withdrawal and relapse differ; report symptoms so the plan can be adjusted.
Pregnancy or breastfeeding?
Discuss benefits and risks; do not abruptly stop psychiatric treatment. Early heart-defect and late newborn risks need review. Brisdelle is contraindicated in pregnancy. If nursing, report infant feeding or weight problems.
Are all versions the same?
No. Doses and approved uses differ. Brisdelle is not an antidepressant-dose substitute. If prescribed liquid for tapering, shake and measure the exact prescribed amount.
Storage & safety
Store securely in the original container and follow its temperature instructions; never share. Suspected overdose: call U.S. Poison Help 1-800-222-1222 even if initially well. Call 911 for collapse, seizure, breathing difficulty, inability to wake, or imminent self-harm.
