Hello,
Thank you for your query at DoctorSpring.com
You should avoid, but if the pain is unbearable, then you can take one more panadol provided you have had your breakfast. I know it's too eaely for you in the morning, but if you have a meal, or at least a cup of milk, the chances of gastric irritation will be considerably lesser. If you take one more tablet now, avoid taking any more tablets for the next 12 hours.
Hope this was helpful,
Regards.
