Effexor/Wellbutrin/Vyvanse

I have to wait 3-6 months to see a psychiatrist, so I’m hoping someone can help me with drug interactions.

I’ve been on Citalopram (40mg) and Wellbutrin XL (300 mg) for about 8 years (PTSD/MDD/OCD/Bulimia). I recently added Vyvanse (40 mg) because I was diagnosed with ADHD - it’s been amazing for focus and improved my work ethic. Unfortunately, my MDD is worse than ever over the past 8 months. I can’t live like this anymore, and I need something to change. My NP suggested trying Effexor instead of the Citalopram, so that’s where I’m at.

I’m a little scared because she said there could be bad side effects (serotonin syndrome, seizures, etc.), but it might be worth trying.

Anyone else on this combo or have advice/knowledge on these drugs combined?
