What would cause lightheadedness, muscle cramps and some anxiety while on Atenolol, Olmesartan, Diazepam, Alprazolam and Doxylamine Succinate?
Problems are that at the halfway point of the medication switch I was feeling great. The tiredness almost gone and energy to do things (that was the reason for the change), but now at the lowest dose of atenolol/highest of olmesartan I am feeling awful. Tired again, some lightheadedness, muscle cramps, feeling some anxiety. What of what I've been doing would be the likely cause? Too little atenolol? Too much olmestartin? One of them interacting with the benzos and causing symptoms because the benzos are not as effective? It didn't start until a couple of days after the last cuts to the doses I'm stating as current. Any help please?
Not because of Atenolol or Olmesartan
This is Dr Sameer, cardiologist.
Our sweet cardiac medications (Atenolol and Olmesartan) does not generally cause light headedness, tiredness or weakness untill your bp is not getting low.
So please tell me what bp are you maintaining with the above medications.
The symptoms you are telling seems to corelate with low bp. So kindly monitor it.
Benzodiazapines can also cause such symptoms. I am not a specialist with neurology, but if you can decrease the dose to thrice daily or so, than kindly do it.
Rest this is not the side effect of atenolol or olmesartan. You can continue them as usual but kindly monitor the bp.
Thanks and take care
Detailed answer as follows
If your bp is in good range than yes this possibly could be side effects of olmesartan (which are actually seen in <1% patients).
Benzodiazapines are actually enzyme inducer, means they increase the metabolism of other drug and decrease its patency. So Olmesartan should work less with it.
So one thing you can do is change olmesartan to another drug of same catagory which has relatively less adverse effect profile. You can change Olmesartan 20mg to Telmisartan 20mg once daily. Both have similar effect on bp and equally good.
So try this and I hope you should be better.
Thanks and take care
