allergic rhinitis
"My 12 year old son was presented Montelukast in February 2015 for Allergies. It helped really well with controlling reactions and I was happy with it. In Sept 2015 I started noticing that me son was becoming anxious about everything. He stopped playing out with his friends, going to youth clubs and scouts and we even had tears when he had to go to school. He developed a separation anxiety with me and began to have bad night terrors and sleep walking EVERY night, sometimes more than once. The last straw was when he developed a phobia of being sick after a tummy bug to the point that he was avoiding eating incase he bought it back up, he lost 7 pounds in 4 weeks. Hes now under a mental health service for support. This drug has ruined our lives!"
