Dosage Guide

Quick Answer

Bupropion dose varies by formulation and indication — SR/XL formulations are preferred because they produce lower peak concentrations (reduced seizure risk). Always take in the morning or early afternoon — never at night (insomnia). Never crush or split XL tablets. For smoking cessation, start 1–2 weeks before the quit date. Always take the dose your doctor prescribes — never exceed the prescribed limit.

Dose at a Glance

Adult Dose

As prescribed — SR/XL formulations preferred; start low and titrate

Once or twice daily — NEVER at night (insomnia); follow doctor's schedule

Max: Do not exceed prescribed maximum — seizure risk is dose-dependent

Child Dose (As per doctor's advice)

Weight-based dose — consult your doctor

As directed by your doctor

Missed Dose

If you miss a dose, take it as soon as you remember. If the next dose is close, skip the missed dose. NEVER take a double dose — a double dose is dangerous due to seizure risk. Avoid taking a dose at night — it will cause insomnia.

Overdose

Bupropion overdose is serious and can cause seizures, cardiac arrhythmias, or CNS depression. If an excessive dose is taken, contact a doctor or emergency room IMMEDIATELY. Bupropion overdose is potentially life-threatening.

Bupropion Tablet Dosage (Kitni leni hai)

Bupropion Tablet — correct dose and timing are critically important for seizure prevention. Always follow your doctor's prescribed dose — never adjust it yourself.

Adult Dose (Baalgon ke liye)

As prescribed — depending on formulation (SR/XL) and indication
Morning or early afternoon — NEVER AT NIGHT (insomnia)
Never exceed the prescribed maximum — seizure risk is dose-dependent

Starting Dose: As prescribed — start low, titrate gradually

Usual Dose: As prescribed by doctor

Max Daily Dose: Never exceed the prescribed limit — seizure risk

CRITICAL TIMING RULE

Taking Bupropion at night guarantees insomnia. Take it in the morning or early afternoon. If two doses are prescribed, take both during the day, before evening.

XL Tablets — Special Rule

Never crush or split XL tablets. Crushing releases the full dose at once — seizure risk increases dramatically. Swallow the tablet intact.

Child Dose (Bachon ke liye)

Weight-based dose — consult your doctor

A child's dose is always decided by the doctor based on weight and age.

How to Take (Kaise lena hai)

Morning or early afternoon
XL tablets intact — never crush/split
Avoid alcohol
Maintain a consistent daily schedule

Best Time to Take (Kab lena chahiye)

Morning — primary dose
Early afternoon — second dose (if prescribed); before evening

With Food or Empty Stomach (Khali pait ya khane ke baad)

Both are acceptable. Taking XL tablets with food can improve consistency of absorption. Take with food if nausea occurs.

Missed Dose (Dose chhoot jaye to kya karein)

If you miss a dose, take it as soon as you remember. If the next dose is close, skip it. NEVER take a double dose — dangerous due to seizure risk.

Overdose (Zyada Dose)

Bupropion overdose is a serious emergency — seizures and cardiac effects can occur. Go to the emergency room IMMEDIATELY.

Frequently Asked Questions

Bupropion SR aur XL mein kya farq hai?

SR (Sustained Release) is given twice daily; XL (Extended Release) usually once daily. Both are safer than immediate-release because peak blood levels are lower — seizure risk is reduced. Never crush or split XL tablets.

Bupropion subah kyun leni chahiye?

Bupropion blocks norepinephrine and dopamine reuptake — it has an activating effect that causes insomnia if taken at night. Taking it in the morning or early afternoon prevents insomnia. Taking it at night is a common dosing mistake.

Smoking cessation ke liye Bupropion kab shuru karein?

For smoking cessation, bupropion (Zyban) is started 1–2 weeks before the quit date. This allows blood levels to establish, which helps control cravings when you stop smoking. Complete the 12-week course — stopping early increases the chance of relapse.

Bupropion mein dose kabhi increase na karein — kyun?

Bupropion's seizure risk is dose-dependent. Exceeding the maximum therapeutic dose significantly increases seizure probability. Dose changes can only be made under a doctor's supervision.

Kya Bupropion ke sath koi khaas khaana parhez zaroori hai?

Avoid alcohol with Bupropion — it further lowers the seizure threshold. With or without food — both are acceptable. Taking XL tablets with food keeps absorption consistent.
