Dyazide (Hydrochlorothiazide / Triamterene) - Summary

 

-- advertisement --

BOX WARNING

Hyperkalemia

Abnormal elevation of serum potassium levels (greater than or equal to 5.5 mEq/liter) can occur with all potassium-sparing diuretic combinations, including DYAZIDE. Hyperkalemia is more likely to occur in patients with renal impairment and diabetes (even without evidence of renal impairment), and in the elderly or severely ill. Since uncorrected hyperkalemia may be fatal, serum potassium levels must be monitored at frequent intervals especially in patients first receiving DYAZIDE, when dosages are changed or with any illness that may influence renal function.

 

DYAZIDE SUMMARY

DYAZIDE®
(hydrochlorothiazide/triamterene)
Capsules

Each Dyazide capsule for oral use, with opaque red cap and opaque white body, contains hydrochlorothiazide 25 mg and triamterene 37.5 mg, and is imprinted with the product name DYAZIDE and SB. Hydrochlorothiazide is a diuretic/antihypertensive agent and triamterene is an antikaliuretic agent.

This fixed combination drug is not indicated for the initial therapy of edema or hypertension except in individuals in whom the development of hypokalemia cannot be risked.

Dyazide is indicated for the treatment of hypertension or edema in patients who develop hypokalemia on hydrochlorothiazide alone.

Dyazide is also indicated for those patients who require a thiazide diuretic and in whom the development of hypokalemia cannot be risked.

Dyazide may be used alone or as an adjunct to other antihypertensive drugs, such as beta-blockers. Since Dyazide may enhance the action of these agents, dosage adjustments may be necessary.
