Dear friend, welcome and thanks for entrusting your query here at Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
Since you had increased urine amount due to the
water pill (diuretic) HCTZ, you likely have developed severe
electrolyte imbalance.
Low sodium (
hyponatremia) is a common side-effect along with low potassium.
It can cause all these crazy sensations and sometimes
drowsiness and later seizures (fits).
Please consult your doctor and check sodium and potassium levels.
Lisinopril may contribute little. You can take it till things are evaluated. Or switch to an ARB category of anti-hypertensives on doctor’s prescription.
Stop the HCTZ combination. The symptoms may take variable time of few days to normalize.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this answer.
Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
Good Luck! Thank you!!
