Hello? Am david a 24 years male. I was sick some three days ago and treated of pneumoniae. I was took under dosage as follows. -amoxyclav 625 mg 5/7 one tab two times a day -meloxicam 15 mg. 5/7 one tab a day. -cetrizine. 5/7 one tab a day. I realized this evening that I took an overdose on meloxicam and cetrizine after depleting them. I took them one tab in the morning and the other in the evening. Today evening I took only one tab of amoxyclav and am experiencing difficulties in sleep as am experiencing some sudden gnawing pain in the left cerebral cortex just superior of the ear. Am also having some convulsions. What could be the problem. Thanks for the feedback and concern.
