The following adverse reactions associated with the use of Biltricide were identified in clinical studies, published literature or postmarketing reports. Because some of these reactions were 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 adverse reactions were observed in both adults and pediatric patients:
General disorders and administration site conditions: malaise, pyrexia
Nervous system disorders: headache, dizziness
Gastrointestinal disorders: abdominal discomfort, nausea
Skin and subcutaneous tissue disorders: urticaria
Such adverse reactions may be more frequent and/or serious in patients with a heavy worm burden.
Additional adverse reactions reported from worldwide post marketing experience and from publications with Biltricide and various formulations of praziquantel include:
Blood and lymphatic system disorders: eosinophilia
Cardiac disorders: arrhythmia (including bradycardia, ectopic rhythms, ventricular fibrillation, AV blocks)
Ear and labyrinth disorders: vertigo, tinnitus
Eye disorders: visual disturbance
Gastrointestinal disorders: abdominal pain, bloody diarrhea, vomiting
General disorders and administration site conditions: polyserositis, asthenia, fatigue, gait disturbance
Hepatobiliary disorders: hepatitis
Immune system disorders: allergic reaction, generalized hypersensitivity, anaphylactic reaction
Metabolism and nutrition disorders: anorexia
Musculoskeletal and connective tissue disorders: myalgia
Nervous system disorders: convulsion, somnolence, intention tremor
Respiratory, thoracic and mediastinal disorders: pneumonitis, dyspnea, wheezing
Skin and subcutaneous tissue disorders: pruritus, rash, Stevens-Johnson syndrome
Pediatric patients 1 to 17 years of age treated with Biltricide and various formulations of praziquantel experienced similar adverse reactions as those observed in adult patients.
