Fosinopril and Hydrochlorothiazide (Fosinopril Sodium / Hydrochlorothiazide) - Side Effects and Adverse Reactions

 
 



ADVERSE REACTIONS

Fosinopril sodium and hydrochlorothiazide tablets has been evaluated for safety in over 660 patients with hypertension; approximately 137 of these patients were treated for more than one year. The observed adverse events were generally mild, transient, and similar to those seen with fosinopril and hydrochlorothiazide taken separately. There was no relationship between the incidence of side effects and age.

In placebo-controlled clinical trials of fosinopril sodium and hydrochlorothiazide, the usual duration of therapy was two months. Adverse clinical or laboratory events led to discontinuation of therapy by 4.3% of 368 placebo- treated patients and by 3.5% of 660 fosinopril sodium and hydrochlorothiazide-treated patients.

The most common reasons for discontinuation of therapy with fosinopril sodium and hydrochlorothiazide in U.S. studies were headache (0.3%), cough (0.3%; see PRECAUTIONS), and fatigue (0.2%).

The side effects considered probably or possibly related to study drug that occurred in placebo-controlled trials in more than 2% of patients treated with fosinopril sodium and hydrochlorothiazide are shown in the table below.

Reactions Possibly or Probably Drug-Related (Incidence in Placebo Controlled Studies)
Fosinopril sodium and hydrochlorothiazide (N = 660) % Placebo (N = 368) %
Headache 7 12.8
Cough 5.6 1.1
Fatigue 3.9 2.4
Dizziness 3.2 2.2
Upper Respiratory Infection 2.3 2.7
Musculoskeletal Pain 2 1.9

Other side effects considered possibly or probably related to study drug that occurred in controlled trials in 0.5% to < 2% of patients treated with fosinopril sodium and hydrochlorothiazide, and rarer but clinically significant events regardless of causal relationship were:

General: Chest pain, weakness, fever, viral infection.

Cardiovascular: Orthostatic hypotension (seen in 1.8% of fosinopril sodium and hydrochlorothiazide patients and 0.3% of placebo patients; no patients discontinued therapy due to orthostatic hypotension), edema, flushing, rhythm disturbance, syncope.

Dermatologic: Pruritus, rash.

Endocrine/Metabolic: Sexual dysfunction, change in libido, breast mass.

Gastrointestinal: Nausea/vomiting, diarrhea, dyspepsia/heartburn, abdominal pain, gastritis/ esophagitis.

Immunologic: Angioedema (see WARNINGS: Head and Neck Angioedema and Intestinal Angioedema).

Musculoskeletal: Myalgia/muscle cramps.

Neurologic/Psychiatric: Somnolence, depression, numbness/paresthesia.

Respiratory: Sinus congestion, pharyngitis, rhinitis.

Special Senses: Tinnitus.

Urogenital: Urinary tract infection, urinary frequency, dysuria.

Laboratory Test Abnormalities: Serum electrolytes, uric acid, glucose, magnesium, cholesterol, triglycerides, and calcium (see PRECAUTIONS). Neutropenia.

Antihypertensive monotherapy with fosinopril has been evaluated for safety in more than 1500 patients, of whom approximately 450 patients were treated for a year or more. The observed adverse events included events similar to those seen with fosinopril sodium and hydrochlorothiazide; in addition, the following others have also been reported with fosinopril:

Cardiovascular: Angina, myocardial infarction, cerebrovascular accident, hypertensive crisis, hypotension, claudication.

Dermatologic: Urticaria, photosensitivity.

Endocrine/Metabolic: Gout.

Gastrointestinal: Pancreatitis, hepatitis, dysphagia, abdominal distention, flatulence, appetite/weight change, dry mouth.

Hematologic: Lymphadenopathy.

Musculoskeletal: Arthralgia.

Neurologic/Psychiatric: Memory disturbance, tremor, confusion, mood change, sleep disturbance.

Respiratory: Bronchospasm, laryngitis/hoarseness, epistaxis, and (in two patients) a symptom-complex of cough, bronchospasm, and eosinophilia.

Special Senses: Vision disturbance, taste disturbance, eye irritation.

Urogenital: Renal insufficiency.

Laboratory Test Abnormalities: Elevations (usually transient and minor) of BUN and creatinine have been observed, but these have not been more frequent than in parallel patients treated with placebo. The hemoglobin in fosinopril-treated patients generally decreases by an average of 0.1 g/dL, but this nonprogressive change has never been symptomatic. Leukopenia and eosinophilia have also been reported.

Serum levels of liver function tests (transaminases, LDH, alkaline phosphatase and serum bilirubin) have occasionally been found to be elevated, and these elevations have lead to discontinuation of therapy in 0.7% of patients. Other risk factors for liver dysfunction have often been present in these cases; in any event the elevations generally have resolved after discontinuation of therapy with fosinopril.

Other Adverse Events Reported with ACE Inhibitors

Other adverse effects reported with ACE inhibitors include cardiac arrest; pancytopenia, hemolytic anemia; aplastic anemia; thrombocytopenia; bullous pemphigus, exfoliative dermatitis; and a syndrome that may include one or more of arthralgia/arthritis, vasculitis, serositis, myalgia, fever, rash or other dermopathy, positive ANA titer, leukocytosis, eosinophilia, and elevated ESR.

Hydrochlorothiazide has now been extensively prescribed for many years, but there has not been enough systematic collection of data to support an estimate of the frequency of the observed adverse reactions. Within organ-system groups, the reported reactions are listed here in decreasing order of severity, without regard to frequency.

Cardiovascular: Orthostatic hypotension (may be potentiated by alcohol, barbiturates, or narcotics).

Gastrointestinal: Pancreatitis, jaundice (intrahepatic cholestatic), sialadenitis, vomiting, diarrhea, cramping, nausea, gastric irritation, constipation, and anorexia.

Hematologic: Aplastic anemia, agranulocytosis, leukopenia, thrombocytopenia, and hemolytic anemia.

Immunologic: Necrotizing angiitis, Stevens-Johnson syndrome, respiratory distress (including pneumonitis and pulmonary edema), anaphylactic reactions, purpura, urticaria, rash, and photosensitivity.

Metabolic: Hyperglycemia, glycosuria, and hyperuricemia.

Musculoskeletal: Muscle spasm.

Neurologic: Vertigo, lightheadedness, transient blurred vision, headache, paresthesia, xanthopsia, weakness, and restlessness.
