I don't take Celexa, but I am on SSRIs, and I've had some trouble with my depression and anxiety since surgery. Okay, that's an understatement.
I have major depressive disorder and generalized anxiety disorder, along with panic attacks. I was diagnosed over ten years ago, and I've been on a variety of medications since diagnosis. Both the depression and anxiety have been treated to remission successfully on multiple occasions. Before surgery, they were problematic, but it was usually just a matter of finding the proper dosage of a drug.
After surgery, things got a lot more difficult for me. At about three months out (so the same stage as you), we bumped my dosage for the first time. I was on Paxil then. I think I was on 40 mg at the time of surgery, and, at three months out, we bumped up to 60 mg. No change. So, about two months later, we transitioned over to Zoloft. Cross-tapered until I was on 150 mg of Zoloft, which is the recommended max. dosage. Very little therapeutic effect. Before surgery, Zoloft had been one of the drugs that I had had the best luck with. I believe I was on it for four years at one point, which is the longest I'd ever lasted on a single drug. We eventually went up to 250 mg of Zoloft, but I had no luck with it.
For me, the issue is malabsorption. I do not absorb SSRIs in the same manner after surgery. I went off the 250 mg of Zoloft in a week. That is a ridiculously fast taper. If the drug had been making it into my bloodstream, I would have had some nasty side effects from going off it so fast. But, nothing happened. The pills were not making it into my bloodstream, and they were not helping with my depression.
Right now, I'm working with a different psychiatrist. We've used a liquid suspension of Zoloft, which did get better therapeutic effects, but I couldn't tolerate the formulation. So, now I'm crushing Zoloft and mixing it with applesauce. The theory is that the crushed pills are more bioavailable. And it is helping a bit more than taking the pills, which I would split in half. I've also added other medications. I currently take Abilify and Vyvanse, both of which help with my mood. But, my RNY will likely affect the treatment of my psychiatric issues for the rest of my life.
Okay, sorry for the book. Back to your questions. At your stage in the game, I wouldn't panic too much. You still have a lot of hormonal issues going on. You're in the rapid weight loss stage, so your fat cells are releasing stored hormones as they shrink. This can wreak havoc on your emotions, making you moody, anxious, and depressed. Your body is also still recovering from the trauma of surgery, as well as the changes that are occurring in your post-op life. It's very likely that things will normalize.
In the meantime, I'd suggest consulting with a qualified psychiatrist. While your PCP is a great place to start, if you're feeling like your depression is worsening, I'd see a specialist about adjusting your dosage or trying a different medication.
I wish you all the best. Depression sucks, and the process of finding what works for you is grueling.
