[/INST] Hello, I couldn't make a decision without a thorough evaluation of your condition, but it sounds like 320/25 is a little too much for me. We usually don't change the dosage even if the blood pressure is lower than desired when the patient has no symptoms. When the patient feels tired or dizzy or weak and there is no good explanation for these symptoms besides the Chat Doctor.  In patients like you, I prefer to move slowly - for example by changing the dosage to 320/12,5. Please keep in mind that you shouldn't change your regimen without your doctors' approval. Also, please consider that these blood pressure excursions may be transient due to pain or anti-inflammatory  </s>
