Sometimes pharmacist will say there are no significant
interactions when there can be a minor interaction like additive efffect
interactions, increase/decrease, hepatic metab. inhibited, decr. conversion to active metabolite.
With Zoloft and BuSpar the interaction is a pharmacodynamic type interaction. There is an additive effect. Both increase serotonin levels. Contraindicated unless benefits outweigh risks and no alternatives available.
