<s>[INST] hi I have Sinitus and before using the NeilMed nasual rinse I had a perfect blood pressure. Now when I visit the doctor on the last vist my blood pressure was high could the NeilMed nasual wash be the reason. I have never has high blood pressure before. [/INST] Hi and thanks for this query. I am so sorry to hear about this increased blood pressure that you have reported. A single increased blood pressure is no reason to freak out. Follow up and get more measurements to see if this is a permanent increase or not. If it were just a one time increase, it needs no further attention. It is unlikely for this product to cause increased blood pressure. I hope this helps. I wish you well. Thank you so much for using our services and do feel free to ask for more information and clarifications if need be. </s>
