If someone has taken two amoxicillin already with no side effects plus taken them b4 is it likely they could still have serious allergic reation?

Not likely: i would expect a reaction to happen fairly soon after the drug was taken. however delayed allergy reactions are not that common

Unlikely: There would be an extremely low likelihood. However people can develop allergies to medicines that they've take previously without a reaction.

Yes it is possible: Hi, It is possible to have an allergic reaction to a medicine that you have previously taken before without problems. In fact, it is more likely to occur with medicines you have taken before. Minor allergic reactions can be treated with OTC Benadryl(diphenhydramine). If you experience any lip or tongue swelling, difficulty breathing or wheezing, lightheadedness, please seek immediate treatment.

Possible: to develop an allergic reaction to penicillin even if you took it before without a problem. If you think you are having a reaction seek medical attention now.
