Psychiatrist Questions Antidepressants

Can antidepressants cause low BP?

My father is 74 years old. He has been on antidepressants, and yesterday his BP went down very badly. Could this be a result of the antidepressant medicines that he is having?

This is possible with certain antidepressants.
Possibly, it depends on the antidepressant. I would advise discussing with his provider.
Some could, but no usually, especially if he has been on the same one for a while. Trazodone and the old TCA antidpressants can. Some antipsychotics that they use can cause it. Seroquel or Quetiapine and most any of them.

This is not a question that can be well answered by yes or no. It is best answered by his medical doctor who can evaluate the many variables that can be involved.

The question was answered.
It depends which anti-depressant he is taking. Some can, but most don't. You should call the doctor who prescribed it for him and ask him.

Yes, some antidepressants can cause BP fluctuations. Also, at that age, hydration is important and can be a frequent cause of hypotension or low BP.
It depends on what kind of antidepressant he is on and what other medical condition he has. Particularly at this age, it becomes a little more complicated as our liver and kidneys are not as efficient as they were before. Some antidepressants actually increase the blood pressure and some tend to decrease it, but not much.
Antidepressants can have varied side effects depending on which one. I recommend reaching out to his prescribing medical provider and address your concerns as well as have him be evaluated by his primary care provider for other causes.
Most probably it may not be due to antidepressant medications, he needs medical evaluation.
