Is Losartan causing my Insomnia and other symptoms?

Typically when you get into a high dose of any one blood pressure medication is when side effects rear their ugly head. All could be from 100 mg losartan. Talk to your doctor about lowering losartan and adding a third medication of a different class. I hope this helps

Hi, Nicolas!
All your symptoms seem as if they could be related to the medications but side effects generally resolve within days to a couple of weeks.
"Common (1% to 10% of users): Nasal congestion"
"Common (1% to 10% of users): Abdominal pain, diarrhea, dyspepsia"
"Common (1% to 10% of users): Insomnia"
"Frequency not reported: Anxiety, anxiety disorder"
Bystolic could also be contributing to the diarrhea, insomnia, and anxiety:
"Uncommon (0.1% to 1% of users): Nightmares, insomnia, anxiety"
"Common (1% to 10% of users): Constipation, diarrhea"
I wonder if you shouldn't contact your doctor and get their professional advice about these medications and the combination.
Best regards and I hope you'll be getting your Zzzz's soon.
