During the placebo-controlled clinical trials, the following undesirable effects were observed, classified as follows: very often (≥1/10), often (≥1 / 100, <1/10) infrequently (≥1 / 1000, <1/100), rarely (≥1 / 10000, <1/1000) and very rarely (<1/10000), the frequency is not set:
From the digestive system:
Often: signs and symptoms of a disorder of the gastrointestinal tract (abdominal pain, nausea, vomiting, diarrhea, flatulence).
Infrequently: pancreatitis. *
From the liver and bile ducts:
Often: increased activity of serum transaminases.
Infrequently: cholelithiasis.
Rarely: hepatitis.
From the musculoskeletal system and connective tissue:
Infrequent: muscle damage (eg, diffuse myalgia, myositis, muscle spasm and muscle weakness).
Vascular disorders:
Infrequent: thromboembolism (pulmonary embolism and deep vein thrombosis of lower extremities). *
From the blood and lymphatic system:
Rarely: a decrease in hemoglobin and leukocytes.
From the nervous system:
Infrequently: a headache.
Rarely: increased fatigue, dizziness.
On the part of the genitals:
Infrequent: erectile dysfunction.
From the skin and subcutaneous fat:
Infrequent: skin reactions of hypersensitivity (for example, skin rash, dermal itching, urticaria).
Rarely: alopecia, photosensitivity reactions.
From the immune system:
Rarely: hypersensitivity reactions.
Laboratory indicators:
Infrequent: increased serum creatinine concentration.
Rarely: an increase in the concentration of urea nitrogen in the blood serum.
* In a clinical study in patients with type 2 diabetes mellitus who received fenofibrate, a statistically significant increase in the incidence of pancreatitis and pulmonary embolism was observed compared with placebo.In the same study, a statistically unreliable increase in cases of deep vein thrombosis was revealed.
In the period of post-marketing application there were spontaneous reports of a number of side effects. According to the available data, it is impossible to establish the exact frequency of these effects, therefore it is classified as "frequency not established".
On the part of the respiratory system: interstitial lung disease.
From the musculoskeletal system and connective tissue: rhabdomyolysis.
From the liver and bile ducts: jaundice, complications of cholelithiasis (for example, cholecystitis, cholangitis, biliary colic).
From the skin and subcutaneous fat: severe skin reactions (eg, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis).
