    About Bupropion

    Bupropion inhibits the reuptake of norepinephrine and dopamine. It tends to be energising rather than sedating, does not usually cause the sexual side effects or weight gain associated with SSRIs, and is often added to an SSRI when that is not enough on its own. It is also an effective aid to stopping smoking, and it is one of the two ingredients in the weight-management drug Contrave.

    The formulation matters. Immediate-release tablets are taken up to three times a day; sustained-release (SR) twice a day; extended-release (XL) once a day. The same daily milligram total in different forms is not the same treatment, and pharmacies cannot substitute between them. Bupropion lowers the seizure threshold in a dose-dependent way, which is why the release form, the maximum dose and the spacing of doses are set carefully and why it is avoided in people with seizure disorders or eating disorders.

    Insomnia, dry mouth, headache and agitation are the common side effects. Taking the last dose earlier in the day helps with sleep. The class boxed warning about suicidal thinking in young people applies.

    Why the cash price for Bupropion differs from pharmacy to pharmacy

    The three release forms have very different acquisition costs. Immediate-release and SR tablets are inexpensive generics; XL tablets cost pharmacies more, and the 450 mg XL strength more again. A pharmacy’s cash price for bupropion therefore depends heavily on which form and strength is written, before any difference in mark-up.

    Generic XL tablets from different manufacturers have historically shown enough variation that the FDA withdrew approval from some versions years ago. Pharmacies that stock one manufacturer’s XL product may price it above another’s, and some patients have a preference. It is reasonable to ask which manufacturer you are getting.

    Ways to pay less for Bupropion without insurance

    • Ask your prescriber whether the SR form taken twice daily is acceptable for you; it is usually cheaper than XL.
    • If you are on XL, ask whether two tablets of a lower strength or one tablet of a higher strength is cheaper at your pharmacy; the answer varies.
    • Ask for a ninety-day prescription once your dose is stable.
    • Ask which manufacturer’s generic the pharmacy stocks and whether it can order an alternative.
    • Upload your prescription to Script Unlock so licensed pharmacies can quote their cash price for the exact form. You pay the pharmacy directly.

    How Script Unlock gets you a cash price for Bupropion

      You compare the responses, pick a pharmacy, and pay that pharmacy directly when you collect. Script Unlock never takes a patient payment and never sets the price.
