I've taken my birth control pill (Gianvi) on a daily basis as directed and was wondering if my depression medicine (Effexor) could lower the effectiveness rate of it.
Hello. I do not see a drug interaction between the two. However, you should read the warnings regarding pregnancy., just in case.
To check medication interactions there is an alphabet at the top of the page with a search box. You can type in the name of your medication and review all side effects and drug interactions. If you have not done so already, be sure to check Effexor which has a number of interactions and side effects.
Good luck to you.

Applies to: Gianvi (drospirenone/ethinyl estradiol)
The coadministration with grapefruit juice may increase the bioavailability of oral estrogens. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall induced by certain compounds present in grapefruits. In a small, randomized, crossover study, the administration of ethinyl estradiol with grapefruit juice (compared to herbal tea) increased peak plasma drug concentration (Cmax) by 37% and area under the concentration-time curve (AUC) by 28%. Based on these findings, grapefruit juice is unlikely to affect the overall safety profile of ethinyl estradiol. However, as with other drug interactions involving grapefruit juice, the pharmacokinetic alterations are subject to a high degree of interpatient variability. Also, the effect on other estrogens has not been studied.
