Reaction to...?

Eyes swollen and red after using new eye drops and taking 1ml milk of magnesia this morning. Had poos within 1 hour of taking milk of magnesia. Gave 2 ml cetirizine antihistamine- George was coughing and coughing in a choking sort of way.

45 minutes later after antihistamine...

Update: George had another reaction like this on Monday 29th June. It was the milk of magnesia. Antihistamine was given again. Have started lactulose 5ml twice a day.
