Can I use topical Caladryl Clear (pramoxine HCI 1% + zinc acetate 0.1%), topical hydrocortisone (1%), oral Zyrtec (cetirizine HCI 10mg), and oral Advil (ibuprofen 200mg) at the SAME TIME? Please let me know, I have really bad mosquito bites and can t stop itching. Some bites I ve scratched to the point of open sores. The bites are everywhere, so I d be applying the topical ointments (hydrocortisone and Caladryl) over large parts of my body.
