Decreases in valproic acid levels that may fall below the therapeutic range have been reported when
valproic acid was co-administered with carbapenem agents. The lowered valproic acid levels can lead
to inadequate seizure control; therefore, concomitant use of ertapenem and valproic acid/sodium
valproate is not recommended and alternative antibacterial or anti-convulsant therapies should be
considered.

Furosemide and torasemide
Oral co-administration of aliskiren and furosemide had no effect on the pharmacokinetics of aliskiren
but reduced exposure to furosemide by 20-30% (the effect of aliskiren on furosemide administered
intramuscularly or intravenously has not been investigated). After multiple doses of furosemide
(60 mg/day) co-administered with aliskiren (300 mg/day) to patients with heart failure the urinary
sodium excretion and the urine volume were reduced during the first 4 hours by 31% and 24%,
respectively, as compared to furosemide alone. The mean weight of patients concomitantly treated
with furosemide and 300 mg aliskiren (84.6 kg) was higher than the weight of patients treated with
furosemide alone (83.4 kg). Smaller changes in furosemide pharmacokinetics and efficacy were
observed with aliskiren 150 mg/day.

There is no experience from controlled clinical trials with concomitant use of Samsca and other
treatments for hyponatremia such as hypertonic sodium chloride solution, oral sodium formulations,
and medicinal products that increase serum sodium concentration. Medicinal products with high
sodium content such as effervescent analgesic preparations and certain sodium containing treatments
for dyspepsia may also increase serum sodium concentration. Concomitant use of Samsca with other
treatments for hyponatremia or other medicinal products that increase serum sodium concentration
may result in a higher risk for developing rapid correction of serum sodium (see section 4.4) and is
therefore not recommended during initial treatment or for other patients with very low baseline serum
sodium concentrations where rapid correction may represent a risk for osmotic demyelination (see
section 4.4).

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 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

of lactic acidosis induced by possible functional renal
failure linked to hydrochlorothiazide.

diazoxide hydrochlorothiazide, with beta blockers may increase the
risk of hyperglycaemia. Thiazide diuretics, including
hydrochlorothiazide, may enhance the hyperglycaemic

Cytotoxic agents Thiazides, including hydrochlorothiazide, may reduce the
renal excretion of cytotoxic agents (e.g.

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.

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 Dafiro HCT and NSAIDs may lead to worsening of
cyclooxygenase-2 renal function and an increase in serum potassium.

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.
antidiabetic agents)
− 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
affecting serum sodium by concomitant administration of medicinal products such
level as antidepressants, antipsychotics, antiepileptics, etc.
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
de pointes medicinal products that could induce torsades de pointes,
in particular Class Ia and Class III antiarrhythmics and
some antipsychotics.

hydrochlorothiazide, may increase the incidence of
hypersensitivity reactions to allopurinol.
Methyldopa There have been isolated reports of haemolytic anaemia

As sodium zirconium cyclosilicate is not absorbed or metabolised by the body, and does not
meaningfully bind other medicinal products, there are limited effects on other medicinal products.
Sodium zirconium cyclosilicate can transiently increase gastric pH by absorbing hydrogen ions and
can lead to changes in solubility and absorption kinetics for co-administered medicinal products with
pH-dependent bioavailability. In a clinical drug-drug interaction study conducted in healthy subjects
co-administration of sodium zirconium cyclosilicate with amlodipine, clopidogrel, atorvastatin,
furosemide, glipizide, warfarin, losartan or levothyroxine did not result in clinically meaningful drug-
drug interactions. Consistent with co-administration of dabigatran with other gastric acid modifiers,
dabigatran Cmax and AUC values were approximately 40% lower when co-administered with sodium
zirconium cyclosilicate. No dose adjustments or separation of time of dosing are required for any of
these medicinal products. However, sodium zirconium cyclosilicate should be administered at least
2 hours before or 2 hours after oral medicinal products with clinically meaningful gastric pH
dependent bioavailability.
