"buPROPion and rasagiline (Major Drug-Drug)

CONTRAINDICATED: According to the manufacturer, the acute toxicity of bupropion may be potentiated by coadministration of monoamine oxidase inhibitors (MAOIs). The mechanism of interaction has not been described.

MANAGEMENT: Concurrent use of bupropion with MAOIs or other agents that possess MAOI activity (e.g., furazolidone, linezolid, procarbazine) is considered contraindicated. At least 14 days should elapse between discontinuation of MAOI therapy and initiation of treatment with bupropion

Most pharmacies have FDA guidelines for drug interactions in their pharmacy computer program For each of the pharmacy customers, the program will automatically search the interactions of a new prescription with the customers current prescriptions and if it discovers an adverse interaction, by law, they are unable to fill the order until they have advised the prescribing physician of the interaction and suggest other possiblities.

I understand the above to say wait until your doctor gets back and has a chance to speak to your pharmacist. If you cannot wait, get a second opinion.
