Drug interaction
Hydrochlorothiazide increases plasma concentration fluconazole. Increased hypotensive effect with: ACE inhibitors, alcohol, adrenergic neurone blockers, aldesleukin, α-blockers, alprostadil, general anaesthetics, antipsychotics, anxiolytics and hypnotics, baclofen, β-blockers, calcium-channel blockers, clonidine, diazoxide, epoetin, hydralazine, levodopa, MAOIs, methyldopa, minoxidil, monoxidine, nitrates, NSAIDs, oestrogens, sodium nitroprusside, tizanidine, phenothiazines. Increased risk of renal impairment with aspirin (in doses >300 mg daily), NSAIDs. Hypotensive effect antagonised by aspirin, corticosteroids, indomethacin, ketorolac. Increased risk of hyperkalaemia with potassium-sparing and aldosterone antagonists, drospirenone (monitor serum potassium during 1st cycle), epoetin, heparin, ketorolac, potassium salts. Increased risk of hypersensitivity with allopurinol (especially in renal impairment). May antagonise hypoglycaemic effects of antidiabetics. Increased risk of hypercalcaemia with calcium salts and vitamin D. Increased risk of hyponatraemia with chlorpropamide. Increased risk of hypermagnesaemia with ciclosporin. Absorption may be reduced by colestipol and colestyramine (take at least 2 hr apart). Potentially Fatal: Increased risk of nephrotoxicity and ototoxicity with platinum compounds, aminoglycosides. Hypokalaemia caused by diuretics may cause cardiac toxicity with amiodarone (interaction may occur for several weeks or months due to long halflife of amiodarone). Increased risk of nephrotoxicity and hyperkalaemia with ciclosporin. Reduced excretion of lithium (risk of lithium toxicity with diuretics).
