I am currently taking carbamazepine for BP disorder type II, and I noticed it's getting hard to breath, l had the same symptom a few months back, went to several especialists but none of them found any respiratory or circular problem. It turned out to be zopiclone I was taking to sleeping. I am not taking zopiclone anymore.
Now the only medications I am taking are carbamazepine for BP II and anti inflammatory for my sciatica.
The only way to know if it's a medication or anxiety causing this is to stop using them. You should not stop carbazepine but diclofenac can be stopped a bit to see if it is the cause if even tho I don't think it can cause shortness of breath. I would have my blood pressure checked too. Mionevrix is okay to stop too to see if it's the cause.
The odds are very high that your problem is anxiety.
You cannot know for sure that it was not carbamazepine causing the problem. Sometimes, when you use two or more meds together, they interact and increase or decrease each other's effects. This happens with carbamazepine and diclofenace (I dont know about mionevrix). When you take both together, the level of carbamazepine in your blood increases. So, what may have happened is that once you stopped taking diclofenac, the level of carbamazepine in your blood went down. Maybe this relieved you of your symptoms.
You will still need to take some meds for the pain, isnt it? I think you should visit your doctor - he could prescribe medicines which have less interaction.
The interactions with carbamazepine are usually suggesting a decrease levels/effects in the drugs taken with carbamazepine (hepatic metabolic induced). Looks like it's not the case with carbamazepine and diclofenac. I checked interactions with carbamazepine + diclofenac epolamine topical/diclofenac ophtalmic/diclofenac potassium/diclofenac sodium/diclofenac topical.
You are correct. The usual interactions suggest a decrease in levels of the other drugs taken with carbamazepine.
Try searching for 'carbamazepine metabolism' and 'diclofenac metabolism'. It shows that both meds are metabolized by CYP3A4. Diclofenac may decrease levels of CYPA4 (search 'diclofenac inactivation CYP3A4); this could potentially lead to increased levels of carbamazepine.
I could not find any direct information regarding this interaction, so it seems that it is not something that happens very frequently. On the other hand, having shortness of breath is also rare with these meds; so it is possible that an infrequent interaction could be the cause.
Considering there is not much information on such an interaction, I think you were right in suggesting anxiety to be the most likely cause of the shortness of breath. What made me think otherwise was that on the previous occasion, it was when zopiclone (again metabolized by CYP3A4) was on that the symptoms occurred.
So the cause is likely to be one of the meds. Probably diclofenac, but we can’t rule out carbamazepine either.
Yes indeed if they use the same enzyme then it would suggest a slower breakdown into metabolites therefore it can increase the levels of both medications. If diclofenac interfere with the enzyme that is used to metabolize carbamazepine then yes increased levels are suggested.
