If you have the extra money, great- take her to the vet, if you don' t, of course you do the best you can with what you have. Both what you have in hand, and what you can find out by asking.
What ever you take is NOT good enough for the animals. If you gave a cat a piece of tylenol for it's arthritis, you would likely kill it. Giving tylenol to a dog is not the safest anti-inflammatory, but it is not outright poison. It works fine, but they do not metabolize it as well as a person would. Good old aspirin can be a safe and super cheap med for an old stiff dog- as long as you use the right amount for it's size. There are certain classes of antibiotics that are fine for people, but usually end up killing the pet that the person was trying to help by giving. People meds and pet meds do not always mesh well. Often they do, most veterinary meds are re-labled people meds. But you do know that different species react differently to different chemicals- I think most everyone knows the 'chocolate is toxic to pets' thing. I love chocolate, but don't feed it to my dog when he is depressed.
You have access to the wonderful internet as evidenced by your presence here in BYC. You have the right motive, you are trying to help your bird, you just need to do your homework better.
Tylenol and birds are a NO. You asked here, and the kind folks recommended aspirin.
I hope your bird does well, jess
