Co-Diovan (valsartan and hydrochlorothiazide)
is a treatment for high blood pressure usually prescribed for those
patients who did not respond well to treatment with valsartan
The two active ingredients in Co-Diovan complement each other,
resulting in a more powerful medication:
blood pressure reduces the workload of the heart and decreases the
risk of risk of stroke and blood vessel damage.
- Valsartan blocks a hormone called
angiotensin II, which regulates blood pressure and fluid balances.
When the hormone is blocked, blood vessels naturally widen and
urine production increases, both actions which help lower blood
- Hydrochlorothiazide is a diuretic which further
increases urine output by filtering salts out of the bloodstream,
an action which also removes water from the blood. The end result
is a lower overall volume of blood, which reduces blood
Using Co-Diovan to Lower Blood Pressure
Co-Diovan tablets range in strength from 80 to 320 mg of valsartan
and 12.5 to 25 mg of hydrochlorothiazide. Dosage strength will
depend on the patient and the severity of the high blood pressure
and should only be determined by a doctor. The lowest possible dose
is desirable to prevent adverse effects.
Following a few simple guidelines, treatment with Co-Diovan is
of treatment is highly variable. This medication is often given
when valsartan alone is not effective, when the cause of the high
blood pressure is unknown, and when efforts to lower blood pressure
through lifestyle changes are ineffective; all situations which
generally call for long-term treatment.
Never take more of this medication than prescribed, or combine it
with other blood pressure reducing treatments unless specifically
approved by a doctor. Severely low blood pressure is every bit as
dangerous as high blood pressure and can be fatal. Warning signs
include extreme dizziness and fainting. If this occurs, call for
medical help and, if possible, lie down until it
