Hydrochlorothiazideinteractions
hydrochlorothiazide 800 MG Powder for Oral Suspension [Inzirqo]
This is the interactions section of this product’s FDA label — what the manufacturer documented for this drug. It is not a check of your medication list, and a drug missing from it has not been cleared: licensed clinical databases list far more interactions than any single label does. Before combining medicines, ask a pharmacist, who can check everything you take at once and will do it for free.

Drug interactions
NSAID: May lead to increased risk of renal impairment and loss of diuretic and antihypertensive effect.
Cholestyramine and colestipol: Reduced absorption of thiazides Lithium: Increased lithium concentrations and lithium toxicity Antidiabetic drugs: Dosage adjustment of antidiabetic may be required
7.1 Potential for
Other Drugs to Affect INZIRQO Non-Steroidal Anti-Inflammatory Agents: Administration of a nonsteroidal anti-inflammatory agent, including a selective COX-2 inhibitor can reduce the diuretic, natriuretic, and antihypertensive effects of thiazide diuretics. Therefore, when INZIRQO and nonsteroidal anti-inflammatory agents are used concomitantly, check to determine if the desired effect of the diuretic is obtained.
Cholestyramine and Colestipol: Absorption of hydrochlorothiazide is impaired in the presence of anionic exchange resins. Stagger the dosage of INZIRQO and the resin such that INZIRQO is administered at least 4 hours before or 4 to 6 hours after the administration of the resin.
7.2 Potential for INZIRQO to
Affect Other Drugs Lithium: Increases in serum lithium concentrations and lithium toxicity have been reported during concomitant administration of hydrochlorothiazide. Monitor serum lithium levels during concomitant use and adjust the lithium dose during concomitant administration or discontinuation of hydrochlorothiazide. Antidiabetic Drugs (oral agents and insulin): Dosage adjustment of the antidiabetic drug may be required when coadministered with hydrochlorothiazide.
