Dantrolene (infusion) In animals, lethal ventricular fibrillation and
cardiovascular collapse are observed in association with
hyperkalaemia after administration of verapamil and
intravenous dantrolene. Due to risk of hyperkalaemia, it is
recommended that the co-administration of calcium
channel blockers such as amlodipine be avoided in
patients susceptible to malignant hyperthermia and in the
management of malignant hyperthermia.
Tacrolimus There is a risk of increased tacrolimus blood levels when
co-administered with amlodipine. In order to avoid
toxicity of tacrolimus, administration of amlodipine in a
patient treated with tacrolimus requires monitoring of
tacrolimus blood levels and dose adjustment of tacrolimus
when appropriate.
Valsartan Non-steroidal anti- NSAIDS can attenuate the antihypertensive effect of both
and HCT inflammatory drugs angiotensin II antagonists and hydrochlorothiazide when
(NSAIDs), including administered simultaneously. Furthermore, concomitant
selective use of Copalia HCT and NSAIDs may lead to worsening
cyclooxygenase-2 of renal function and an increase in serum potassium.

inhibitors), the treatment is recommended, as well as adequate
acetylsalicylic acid hydration of the patient.

selective NSAIDs
Valsartan Inhibitors of the uptake The results of an in vitro study with human liver tissue
transporter (rifampicin, indicate that valsartan is a substrate of the hepatic uptake
ciclosporin) or efflux transporter OATP1B1 and of the hepatic efflux transporter
transporter (ritonavir) MRP2. Co-administration of inhibitors of the uptake
transporter (rifampicin, ciclosporin) or efflux transporter
(ritonavir) may increase the systemic exposure to
valsartan.
HCT Alcohol, barbiturates Concomitant administration of thiazide diuretics with
or narcotics substances that also have a blood pressure lowering effect
(e.g. by reducing sympathetic central nervous system
activity or direct vasodilatation) may potentiate orthostatic
hypotension.
Amantadine Thiazides, including hydrochlorothiazide, may increase
the risk of adverse reactions caused by amantadine.
Anticholinergic agents The bioavailability of thiazide-type diuretics may be
and other medicinal increased by anticholinergic agents (e.g. atropine,
products affecting biperiden), apparently due to a decrease in gastrointestinal
gastric motility motility and the stomach emptying rate. Conversely, it is
anticipated that prokinetic substances such as cisapride
may decrease the bioavailability of thiazide-type diuretics.
Antidiabetic agents Thiazides may alter glucose tolerance. Dose adjustment of
(e.g. insulin and oral the antidiabetic medicinal product may be necessary.

− Metformin Metformin should be used with caution because of the risk
of lactic acidosis induced by possible functional renal
failure linked to hydrochlorothiazide.
Beta blockers and Concomitant use of thiazide diuretics, including
diazoxide hydrochlorothiazide, with beta blockers may increase the
risk of hyperglycaemia. Thiazide diuretics, including
hydrochlorothiazide, may enhance the hyperglycaemic
effect of diazoxide.
Ciclosporin Concomitant treatment with ciclosporin may increase the
risk of hyperuricaemia and gout-type complications.

Cytotoxic agents Thiazides, including hydrochlorothiazide, may reduce the
renal excretion of cytotoxic agents (e.g.
cyclophosphamide, methotrexate) and potentiate their
myelosuppressive effects.
Digitalis glycosides Thiazide-induced hypokalaemia or hypomagnesaemia may
occur as undesirable effects, favouring the onset of
digitalis-induced cardiac arrhythmias.
Iodine contrasting In case of diuretic-induced dehydration, there is an
agents increased risk of acute renal failure, especially with high
doses of iodine products. Patients should be re-hydrated
before the administration.
Ion exchange resins Absorption of thiazide diuretics, including
hydrochlorothiazide, is decreased by cholestyramine or
colestipol. This could result in sub-therapeutic effects of
thiazide diuretics. However, staggering the dosage of
hydrochlorothiazide and resin such that
hydrochlorothiazide is administered at least 4 hours before
or 4-6 hours after the administration of resins would
potentially minimise the interaction.
Medicinal products The hypokalaemic effect of hydrochlorothiazide may be
affecting serum increased by concomitant administration of kaliuretic
potassium level diuretics, corticosteroids, laxatives, adrenocorticotropic
hormone (ACTH), amphotericin, carbenoxolone,
penicillin G and salicylic acid derivatives or
antiarrhythmics. If these medicinal products are to be
prescribed with the amlodipine /valsartan
/hydrochlorothiazide combination, monitoring of
potassium plasma levels is advised.
Medicinal products The hyponatraemic effect of diuretics may be intensified

Caution is indicated in long-term administration of these
medicinal products.
Medicinal products that Due to the risk of hypokalaemia, hydrochlorothiazide
could induce torsades should be administered with caution when associated with

some antipsychotics.

hydrochlorothiazide, may increase the incidence of
hypersensitivity reactions to allopurinol.

Medicinal products affecting potassium:
The potassium-depleting effect of hydrochlorothiazide is attenuated by the potassium-sparing effect of
irbesartan. However, this effect of hydrochlorothiazide on serum potassium would be expected to be
potentiated by other medicinal products associated with potassium loss and hypokalaemia (e.g. other
kaliuretic diuretics, laxatives, amphotericin, carbenoxolone, penicillin G sodium). Conversely, based
on the experience with the use of other medicinal products that blunt the renin-angiotensin system,
concomitant use of potassium-sparing diuretics, potassium supplements, salt substitutes containing
potassium or other medicinal products that may increase serum potassium levels (e.g. heparin sodium)
may lead to increases in serum potassium. Adequate monitoring of serum potassium in patients at risk
is recommended (see section 4.4).
