A: We would NEVER recommend that you give your parrot any medication that was meant for you. While some medications can be used effectively for both humans and birds, you should always rely on your Avian vet to prescribe medicine for your bird.
First, you have no idea what dosage your bird needs and even if you did, there is no way to ensure the proper dosage just by crushing the pill and mixing it with water. In addition, not all pills can be effectively mixed with water.
Second, not every injury requires an antibiotic and when an antibiotic IS necessary, it's important to have the right TYPE of antiobiotic.
Finally, if your parrot is injured or ill, it is extremely important that he be examined by your certified Avian vet. Bleeding and illness can cause your bird's health to deteriorate very quickly and medical care is urgently needed. Please do not take chances on advice that is questionable - it's simply not worth the risk.
Best wishes.
