Side Effects
Losartan: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice (Cozaar XQ).
Losartan has been found to be generally well-tolerated in controlled clinical trials for hypertension; side effects have usually been mild and transient in nature and have not required discontinuation of therapy. The overall incidence of side effects reported with losartan was comparable to placebo.
In controlled clinical trials for essential hypertension, dizziness was the only side effect reported as drug related that occurred with an incidence greater than placebo in one percent or more of patients treated with losartan. In addition, dose-related orthostatic effects were seen in less than one percent of patients. Rarely, rash was reported, although the incidence in controlled clinical trials was less than placebo.
In these double-blind controlled clinical trials for essential hypertension, the following adverse experiences reported with losartan occurred in ≥ 1 percent of patients, regardless of drug relationship: (see Table 4).

Losartan was generally well-tolerated in a controlled clinical trial in hypertensive patients with left ventricular hypertrophy. The most common drug-related side effects were dizziness, asthenia/fatigue, and vertigo.
In the LIFE study, among patients without diabetes at baseline, there was a lower incidence of new onset diabetes mellitus with losartan as compared to atenolol (242 patients vs 320 patients, respectively, p<;0.001). Because there was no placebo group included in the study, it is not known if this represents a beneficial effect of losartan or an adverse effect of atenolol.
Losartan was generally well-tolerated in a controlled clinical trial in type 2 diabetic patients with proteinuria. The most common drug-related side effects were asthenia/fatigue, dizziness, hypotension and hyperkalemia (see Hypotension and Electrolyte/Fluid Imbalance under PRECAUTIONS).
The following additional adverse reactions have been reported in post-marketing experience: Hypersensitivity: Anaphylactic reactions, angioedema including swelling of the larynx and glottis causing airway obstruction and/or swelling of the face, lips, pharynx and/or tongue has been reported rarely in patients treated with losartan; some of these patients previously experienced angioedema with other drugs including ACE inhibitors. Vasculitis, including Henoch-Schoenlein purpura, has been reported rarely.
Gastrointestinal: Hepatitis (reported rarely), liver function abnormalities, vomiting.
General disorders and administration site conditions: Malaise.
Hematologic: Anemia, thrombocytopenia (reported rarely).
Musculoskeletal: Myalgia, arthralgia.
Nervous System/Psychiatric: Migraine, dysgeusia.
Reproductive system and breast disorders: Erectile dysfunction/impotence.
Respiratory: Cough.
Skin: Urticaria, pruritus, erythroderma, photosensitivity.
Cozaar XQ: Amlodipine besylate: Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Amlodipine besylate has been evaluated for safety in more than 11,000 patients in worldwide clinical trials. In general, treatment with amlodipine besylate was well-tolerated at doses up to 10 mg daily. Most adverse reactions reported during therapy with amlodipine besylate were of mild or moderate severity. In controlled clinical trials directly comparing amlodipine besylate (N=1730) at doses up to 10 mg to placebo (N=1250), discontinuation of amlodipine besylate due to adverse reactions was required in only about 1.5% of patients and was not significantly different from placebo (about 1%). The most common side effects are headache and edema. The incidence (%) of side effects that occurred in a dose related manner are as follows: (See Table 5.)

Other adverse experiences that were not clearly dose related but were reported with an incidence greater than 1.0% in placebo-controlled clinical trials include the following: (See Table 6.)

The following events occurred in <1% but >0.1% of patients in controlled clinical trials or under conditions of open trials or marketing experience where a causal relationship is uncertain; they are listed to alert the physician to a possible relationship:
Cardiovascular: arrhythmia (including ventricular tachycardia and atrial fibrillation), bradycardia, chest pain, hypotension, peripheral ischemia, syncope, tachycardia, postural dizziness, postural hypotension, vasculitis.
Central and Peripheral Nervous System: hypoesthesia, neuropathy peripheral, paresthesia, tremor, vertigo.
Gastrointestinal: anorexia, constipation, dyspepsia1, dysphagia, diarrhea, flatulence, pancreatitis, vomiting, gingival hyperplasia.
General: allergic reaction, asthenia1, back pain, hot flushes, malaise, pain, rigors, weight gain, weight decrease.
Musculoskeletal System: arthralgia, arthrosis, muscle cramps1, myalgia.
Psychiatric: sexual dysfunction (male1 and female), insomnia, nervousness, depression, abnormal dreams, anxiety, depersonalization.
Respiratory System: dyspnea1, epistaxis.
Skin and Appendages: angioedema, erythema multiforme, pruritus1, rash1, rash erythematous and rash maculopapular.
Special Senses: abnormal vision, conjunctivitis, diplopia, eye pain, tinnitus.
Urinary System: micturition frequency, micturition disorder, nocturia.
Autonomic Nervous System: dry mouth, sweating increased.
Metabolic and Nutritional: hyperglycemia, thirst.
Hemopoietic: leukopenia, purpura, thrombocytopenia.
1These events occurred in less than 1% in placebo-controlled trials, but the incidence of these side effects was between 1% and 2% in all multiple dose studies.
The following events occurred in <0.1% of patients: cardiac failure, pulse irregularity, extrasystoles, skin discoloration, urticaria, skin dryness, alopecia, dermatitis, muscle weakness, twitching, ataxia, hypertonia, migraine, cold and clammy skin, apathy, agitation, amnesia, gastritis, increased appetite, loose stools, coughing, rhinitis, dysuria, polyuria, parosmia, taste perversion, abnormal visual accommodation, and xerophthalmia.
Other reactions occurred sporadically and cannot be distinguished from medications or concurrent disease states such as myocardial infarction and angina.
The following additional adverse reactions have been reported in post-marketing experience: Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The following postmarketing event has been reported infrequently where a causal relationship is uncertain: gynecomastia. In postmarketing experience, jaundice and hepatic enzyme elevations (mostly consistent with cholestasis or hepatitis), in some cases severe enough to require hospitalization, have been reported in association with use of amlodipine besylate.
Amlodipine besylate has been used safely in patients with chronic obstructive pulmonary disease, well-compensated congestive heart failure, coronary artery disease, peripheral vascular disease, diabetes mellitus, and abnormal lipid profiles.
COZAAR XQ: The safety of COZAAR XQ has been evaluated in 325 patients treated with losartan/amlodipine combination therapy among 646 essential hypertension patients in 3 clinical trials (study 201, study 301 and study 302) for 8 weeks. Adverse reactions have been ranked under headings of frequency using the following convention: very common (≥ 1/10); common (≥ 1/100, <1/10); uncommon (≥ 1/1,000, <1/100); rare (≥ 1/10,000, <1/1,000); very rare (<1/10,000). (See Table 8.)

Additional information for each active ingredient.
The following adverse reactions have been reported with the components of COZAAR XQ.
Laboratory Test Findings: Cozaar: In controlled clinical trials, clinically important changes in standard laboratory parameters were rarely associated with administration of COZAAR. Hyperkalemia (serum potassium >5.5 mEq/L) occurred in 1.5% of patients in the hypertension clinical trials. In a clinical study conducted in type 2 diabetic patients with proteinuria, 9.9% of patients treated with COZAAR and 3.4% of patients treated with placebo developed hyperkalemia (see Hypotension and Electrolyte/Fluid Imbalance under PRECAUTIONS). Serum potassium should be monitored, particularly in the elderly and patients with renal impairment. Elevations of ALT occurred rarely and usually resolved upon discontinuation of therapy.
Cozaar XQ: Slowed heart rate was observed in some patients 8 weeks after administration of losartan/amlodipine, but the change in heart rate was not clinically significant.
Increased blood creatinine and increased hepatic enzyme were reported in some patients but specific laboratory monitoring is not required.
