More than half of children taking the swine flu drug Tamiflu experience side-effects such as nausea and nightmares.
Studies of children attending four showed that 51 to 53 percent had one or more side-effects from the medication.
The most common side effect was nausea (29 percent), followed by stomach pain or cramps (20 percent) and problems sleeping (12 percent). Almost one in five had a “neuropsychiatric side-effect”, such as inability to think clearly, nightmares and “behaving strangely”.
