Hi, I have gone through your question and understand your concerns.
You are having
photosensitive rash , it is very common side effect of hydrocholorothiazide.
Treatment with escitalopram may occasionally cause blood sodium levels to get too low, a condition known as
hyponatremia, and using it with
hydroCHLOROthiazide can increase that risk. You should seek medical attention if you experience nausea,
vomiting, headache, lethargy, irritability, difficulty concentrating, memory impairment, confusion, muscle spasm, weakness or unsteadiness, as these may be symptoms of hyponatremia. More severe cases may lead to
hallucination, fainting, seizure, coma, and even death. Escitalopram can also affect your blood pressure and
heart rate. You may need a dose adjustment or more frequent monitoring of your blood pressure and pulse to safely use both medications. You should avoid rising abruptly from a sitting or lying position while taking these medications, especially at the beginning of treatment or after an increase in dose.
I suggest you to consult your physician and get some other class of anti-
hypertension like ACE i, CCbs.
Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate to ask. I will be happy to answer your questions.
Wishing you good health.
