Answer
it was difficult to read your question, so there are two answers.

if she was being listless and squirming before you gave her medication then possibly not, chances are fatigue and the infection killed her though honestly there is a reasonable chance that you did, sorry to be blunt, but it is never a good idea to cross human medication and pets, whats poisonous for some animals is a cure for others. humans are essentially animals and have a different make up to guinea pigs. however i do not beleive that many of the things we use would actually kill a guinea pig given that in terms of dietry requirements we are actually surpringly similar as both cannot produce vit c. which means that it was not so much the medicines you gave but rather the quantity. many human medicines are actually poisonous to us, but because we take them in small doses its okay. 2mls to us would be like a pint to a guinea pig, which means she would have drank a pint of poison.

sorry to hear about your pet
