"The US Food and Drug Administration (FDA) is investigating the "rare but serious" risk for slowed or difficult breathing in children 17 and younger treated with the opioid analgesic tramadol.
"This risk may be increased in children tr"...
The following serious adverse reactions are discussed in greater detail in other sections of the labeling:
- Hypoglycemia and related events, like hypoglycemic seizure [see WARNINGS AND PRECAUTIONS].
- Bronchospasm [see WARNINGS AND PRECAUTIONS].
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in clinical practice.
Clinical Trials Experience with HEMANGEOL in Infants with proliferating infantile hemangioma
In clinical trials for proliferating infantile hemangioma, the most frequently reported adverse reactions ( > 10%) in infants treated with HEMANGEOL were sleep disorders, aggravated respiratory tract infections such as bronchitis and bronchiolitis associated with cough and fever, diarrhea, and vomiting. Adverse reactions led to treatment discontinuation in fewer than 2% of treated patients.
Overall, 479 patients in the pooled safety population were exposed to study drug in the clinical study program (456 in placebo-controlled trials). A total of 424 patients were treated with HEMANGEOL at doses 1.2 mg/kg/day or 3.4 mg/kg/day for 3 or 6 months. Of these, 63% of patients were aged 91-150 days and 37% were aged 35-90 days at randomization.
The following table lists according to the dosage the most common adverse reactions (treatment-emergent adverse events with an incidence at least 3% greater on one of the two doses than on placebo).
Table 2: Treatment-emergent adverse events occurring
at least 3% more often on HEMANGEOL than on placebo.
|HEMANGEOL 1.2 mg/kg/day
|HEMANGEOL 3.4 mg/kg/day
The following adverse events have been observed during clinical studies, with an incidence of less than 1%:
Investigations: Decreased blood glucose, decreased heart rate
Compassionate Use Program
More than 600 infants received HEMANGEOL in a compassionate use program (CUP). Mean age at treatment initiation was 3.6 months. Mean dose of HEMANGEOL was 2.2 mg/kg/day and mean treatment duration was 7.1 months.
The adverse reactions reported in the CUP were similar to the ADRs observed during clinical trials but some were more severe.
The following adverse reactions have been identified during post-approval use of propranolol. 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.
These adverse reactions are as follows:
Blood and lymphatic system disorders: Agranulocytosis
Psychiatric disorders: Hallucination
Skin and subcutaneous tissues disorders: Purpura
Read the Hemangeol (propranolol hydrochloride oral solution) Side Effects Center for a complete guide to possible side effects
In the absence of specific studies in children, the drug interactions with propranolol are those known in adults. Consider both the infant's medications and those of a nursing mother.
Pharmacokinetic drug interactions
Impact of co-administered drugs on propranolol: CYP2D6, CYP1A2 or CYP2C19 inhibitors increase propranolol plasma concentration. CYP1A2 inducers (phenytoin, phenobarbital) or CYP2C19 inducers (rifampin) decrease propranolol plasma concentration when co-administered.
Pharmacodynamic drug interactions
Corticosteroids: Patients on corticosteroids may be at increased risk of hypoglycemia because of loss of the counter-regulatory cortisol response; monitor patients for signs of hypoglycemia.This monograph has been modified to include the generic and brand name in many instances.
