I appreciate that there are occasionally differences between brands but this is undoubtedly a topic which receives a excessive amount of attention. It is to be expected that people will believe that more expensive brands are superior. The immense impact that this perception has on patient response should not be underestimated. What people may not realise is that Zoloft, Prozac and other brands still only cost a few cents per box to manufacture, like any mass produced off-patent medication. The inflated price is mostly profit for the manufacturer. Eli Lilly currently sell branded Prozac in the UK for only £1.50 per pack of 30 capsules. How they can justify the US price I do not know.
The excipients used in generics are sometimes the same as the brand, sometimes different. In all cases, bioavailability will be tested. Excipients have a substantial affect on the absorption of some drugs (eg. ciclosporin) but the excipients used in SSRI formulations are mostly inert. Most brands of generic sertraline in the UK have the same or very similar excipients to Lustral/Zoloft.
>He sometimes prescribes double the dose of generic fluoxetine if his patient is switching to it from brand Prozac.
That is not very sensible! Doubling the dose is a very substantial increase and I cannot imagine that it would be appropriate.
