Losartan potassium and hydrochlorothiazide
has been evaluated for safety in 858 patients treated for essential
hypertension and 3889 patients treated for hypertension and left
ventricular hypertrophy. In clinical trials with losartan potassium and
hydrochlorothiazide, no adverse experiences peculiar to this
combination have been observed. Adverse experiences have been limited
to those that were reported previously with losartan potassium and/or
hydrochlorothiazide. The overall incidence of adverse experiences
reported with the combination was comparable to placebo. In
general, treatment with losartan potassium and hydrochlorothiazide was
well tolerated. For the most part, adverse experiences have been mild
and transient in nature and have not required discontinuation of
therapy. In controlled clinical trials, discontinuation of therapy due
to clinical adverse experiences was required in only 2.8% and 2.3% of
patients treated with the combination and placebo, respectively. In
these double-blind controlled clinical trials, the following adverse
experiences reported with losartan-hydrochlorothiazide occurred in ≥1
percent of patients, and more often on drug than placebo, regardless of
drug relationship:

The
following adverse events were also reported at a rate of 1 % or
greater, but were as, or more, common in the placebo group in studies
of essential hypertension: asthenia/fatigue, diarrhea, nausea,
headache, bronchitis, pharyngitis. Adverse events occurred at
about the same rates in men and women. Adverse events were somewhat
more frequent in the elderly compared to non-elderly patients and
somewhat more frequent in Blacks compared to non-Blacks for both the
losartan and hydrochlorothiazide and the control groups. A
patient with known hypersensitivity to aspirin and penicillin, when
treated with losartan potassium, was withdrawn from study due to
swelling of the lips and eyelids and facial rash, reported as
angioedema, which returned to normal 5 days after therapy was
discontinued. Superficial peeling of palms and hemolysis were reported in one subject treated with losartan potassium.
