Brief Answer:
investigation for seconday hypertension and titration
Detailed Answer:
Hello,
in a newly encountered hypertension (or worsening of hypertension) concerns are raised about secondary hypertension (endocrinological disorders, renovascular hypertension, etc). In such cases investigation for such causes should be done.
Regarding treatment, you should follow instructions for proper measurement (2-3 measurements each time, the lowest should be recorded) and if the blood pressure is still out of control then the treatment has to be escalated. Valsartan can be given in higher doses (up to 320mg per day) and a diuretic can also be added. Adding a second drug will be more efficacious than increasing the dose of a single drug.
Remember that most drugs require about a month to show their full potential so you'll have to be patient.
I hope it helps!
Kind Regards!
