Side effects observed in association with the use of MAXZIDE, other combination products containing triamterene/hydrochlorothiazide, and products containing triamterene or hydrochlorothiazide include the following:
Renal: acute renal failure, acute interstitial nephritis, renal stones composed of triamterene in association with other calculus materials, urine discoloration.
Ophthalmic: xanthopsia, transient blurred vision.
Other: muscle cramps and weakness, decreased sexual performance and sialadenitis.
Whenever adverse reactions are moderate to severe, therapy should be reduced or withdrawn.
Altered Laboratory Findings
Creatinine, Blood Urea Nitrogen: Reversible elevations in BUN and serum creatinine have been observed in hypertensive patients treated with MAXZIDE.
Serum Uric Acid, PBI and Calcium: (see PRECAUTIONS).
Other: Elevated liver enzymes have been reported in patients receiving MAXZIDE.

Thiazides may add to or potentiate the action of other antihypertensive drugs.
The thiazides may decrease arterial responsiveness to norepinephrine. This diminution is not sufficient to preclude effectiveness of the pressor agent for therapeutic use. Thiazides have also been shown to increase the responsiveness to tubocurarine.
Lithium generally should not be given with diuretics because they reduce its renal clearance and add a high risk of lithium toxicity. Refer to the package insert on lithium before use of such concomitant therapy.
Acute renal failure has been reported in a few patients receiving indomethacin and formulations containing triamterene and hydrochlorothiazide. Caution is therefore advised when administering non-steroidal anti-inflammatory agents with MAXZIDE (triamterene and hydrochlorothiazide).
Potassium-sparing agents should be used very cautiously, if at all, in conjunction with angiotensin-converting enzyme (ACE) inhibitors due to a greatly increased risk of hyperkalemia. Serum potassium should be monitored frequently.
Drug/Laboratory Test Interactions
Triamterene and quinidine have similar fluorescence spectra; thus MAXZIDE (triamterene and hydrochlorothiazide) may interfere with the measurement of quinidine.
