Side Effects Of Melatonin With Autism

Health professionals with Autism Speaks report that an estimated 44 percent to 83 percent of autistic children struggle with sleep problems, such as insomnia. Treatment with melatonin supplements may help children with autism fall asleep more quickly and stay asleep longer than children who do not take melatonin, according to an April 2009 study published in the "Journal of Clinical Sleep Medicine." The side effects of melatonin in children with autism are similar to those experienced by children and adults with insomnia. Discuss these side effects with your child's pediatrician before initiating treatment with melatonin supplements.

Increased Daytime Fatigue

You may notice that your autistic child appears unusually tired or lethargic during the day while receiving treatment with melatonin supplements. Increased daytime fatigue may make it difficult for your child to remain alert or physically active throughout the day. Your child may take frequent naps or may go to bed earlier than usual. Seek additional guidance from your child's doctor if daytime fatigue becomes bothersome or interferes with your child's normal routine.

Unusually Vivid Dreams

Treatment with melatonin supplements may cause your child to experience unusually vivid dreams while sleeping, BC Children's Hospital explains. These dreams may be disturbing and may cause your child to wake during the night. If your autistic child is troubled by these dreams, consult your pediatrician.

Stomach Pain

Stomach pain may occur as a side effect of melatonin in children with autism. You may notice that your child holds or rubs her stomach or refuses to eat or drink. Seek prompt care from your child's physician if stomach pain becomes severe or persists.

Seizures

Taking 1 mg to 5 mg doses of melatonin may increase your child's risk of experiencing a seizure as a side effect of this supplement, the University of Maryland Medical Center warns. Melatonin should only be given to your autistic child as directed by a medical professional. If your child exhibits signs of a seizure, such as loss of consciousness or unusual body spasms, contact your doctor.
