Uses of Disys: - Hypertension (high blood pressure) Hypertension, Diabetic nephropathy Hypersensitivity to valsartan, hydrochlorothiazide or sulphonamides. Severe hepatic impairment, creatinine clearance <30ml/min, anuria, cirrhosis, biliary obstruction, conditions where there is increased potassium loss (e.g. salt losing nephropathies and pre-renal impairment of kidney function), refractory hypokalaemia, hyponatraemia, hypercalcaemia, hyperuricaemia, history of gout and uric acid stones, untreated Addison's disease. Pregnancy and lactation.

How to use Hydrochlorothiazide + Valsartan: Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Hydrochlorothiazide + Valsartan may be taken with or without food, but it is better to take it at a fixed time. Adult Dose: Hypertension 1 tablet/day PO (80-160 mg valsartan/12.5-25 mg hydrochlorothiazide); may be titrated after 1-2 weeks of therapy; not to exceed 320 mg valsartan/25 mg hydrochlorothiazide daily Renal Dose: Renal impairment: CrCl (ml/min) Dosage Recommendation <30 Not recommended.

Increased antihypertensive effect with other antihypertensive drugs. Monitor potassium frequently if used with potassium supplements, potassium-sparing diuretics, salt substitutes containing potassium, or drugs that may affect potassium levels (e.g. heparin, ciclosporin, drospirenone, amphotericin, corticosteroids, carbenoxolone). Reduced antihypertensive effect of valsartan and increased risk of renal impairment with NSAIDs. May reduce renal clearance of cytotoxic drugs (e.g. cyclophosphamide, methotrexate). Increased serum calcium with vitamin D or calcium salts. Potentially Fatal: Increased lithium levels with valsartan, monitor lithium levels. Increased risk of cardiac arrhythmia with dofetilide, avoid use.

Precaution: DM, postsympathectomy patients. May exacerbate SLE. Monitor serum potassium regularly. Observe for signs of fluid or electrolyte imbalance. Discontinue before testing for parathyroid function. May affect ability to drive or operate machinery. Elderly. Lactation: Discontinue drug, or do not nurse

Valsartan is an angiotensin II receptor antagonist and reduces blood pressure by blocking the vasoconstrictive and aldosterone-secreting effects of angiotensin II. Hydrochlorothiazide is a thiazide diuretic.
