Yes he can hun. When Amelia was poorly she had the same medicine. My doc said to give it to her and give her Calpol and then 4 hours later Calprufen then another Calpol 4 hours later. I was to keep going like this if I thought she needed it (no more than 3 doses of calprufen in 24 hrs and no more than 4 doses of Calpol). I just gave her the anti-b's at regular times throughout the day and her painkillers when she needed them, sticking to the every 4 hour rule above. HTH xxx
