I am allergic to most antibiotics,but due to a UTI that ive had for over 3 years ,my dr decided to get me tested to see if im allergic to penicillans...Dr says im not and can take them safley...SO...I got prescribed amoxillan 500 mgs 3 times daily for 5 days...After i took the first one ,my mood changed,to feeling extremly anxious and hyper..A crawling out of my skin sensation..Also i felt really disconnected at the same time..I do have anxiety normally but this was like exxagerated after taking just one 500 mg amoxcil...Ive read that it can cause these reactions,my question is this..How serious is this reaction and does this mean its a precurser to an severe allergic reaction ,or other CNS reacvtions such as convulsions and seizures..I desperatley need help since this is my last chance antibitic!!I have developed shingles from having this chronic infection and my allergies are way worse , ears hurt and at times get heavy chest from them as well..So i desperatly need an antiobtioc,but am terrifed to take it...WOuld a lower dose be better??Any help would be helpful fro ive become highly depressed over my health and watching it get worrse and worse..I never feel good anymore,and this depression isnt helping..I feel hopeless now about getting better!!Thank you!!
