What are the possible side effects of Allertek?

Pediatric studies were conducted using Allertek hydrochloride. More than 1,300 pediatric patients aged 6 to 11 years with more than 900 receiving Allertec hydrochloride at doses of 1.25 to 10 mg per day were included in controlled and uncontrolled clinical trials conducted in the United States. The duration of treatment ranged from 2 to 12 weeks. Placebo-controlled trials lasting up to 4 weeks included 168 pediatric patients aged 2 to 5 years who received Allertek, most of whom received a single daily dose of 5 mg. An 18-month placebo-controlled trial included 399 patients aged 12 to 24 months treated with Allertek (0.25 mg / kg bid), and another 7-day placebo-controlled trial included 42 patients aged 6 to 11 months treated with Allertek (0.the rate is 25 mg / kg)

Most of the adverse reactions reported in pediatric patients aged 2 to 11 years with the use of Allertek hydrochloride were mild or moderate. In placebo-controlled trials, the frequency of interruptions due to adverse reactions in pediatric patients treated with up to 10 mg of Allertec hydrochloride was rare (0.4% for Allertec hydrochloride versus 1.0% for placebo).

Table 1 lists the side effects that were reported for Allertek hydrochloride 5 and 10 mg in pediatric patients aged 6 to 11 years in placebo-controlled clinical trials in the United States and were more frequent with Allertek hydrochloride than placebo. Of these, abdominal pain was considered treatment-related, and drowsiness appeared to be dose-related: 1.3% in placebo, 1.9% in 5 mg, and 4.2% in 10 mg. Adverse experiences reported in pediatric patients aged 2 to 5 years in placebo-controlled trials were qualitatively similar in nature and generally similar in frequency to those reported in studies with children aged 6 to 11 years

In placebo-controlled studies in pediatric patients aged 6 to 24 months, the frequency of adverse events was the same in the Allertec and placebo treatment groups in each study. Drowsiness was observed with almost the same frequency in patients treated with Allertek hydrochloride and in patients treated with placebo. In a 1-week study in children aged 6 to 11 months, patients treated with Allertek showed greater irritability/fussiness than patients treated with placebo. In an 18-month study in patients 12 months and older, insomnia was more common in patients treated with Allertek compared to patients treated with placebo (9.0% in. 5.3%). Those patients who received Allertek at a dose of 5 mg or more per day compared to patients who received placebo, fatigue was observed (3.6% v. 1.3%) and malaise (3.6% v. 1.8%) met more often
