I am aware that antibiotics, pain medication and other medications may cause adverse reactions such as redness and swelling of tissues, pain, itching, nausea, vomiting, dizziness coordination. Miscarriage, cardiac arrest, which can be increased by use of alcohol or other drugs, blood clot in the legs, heart, lungs, or brain, low blood pressure, heart attack, stroke, paralysis, and brain damage. After injection, I may have prolonged numbness or irritation in the area of injection. If I use Nitrous Oxide, Atarax, Xanax, Halcion, Versed, Demerol, Fentanyl, or other sedative more risks including but exclusive of passing out, severe shock, stopped breathing, or stopped heartbeat are possible. I will arrange for someone to drive me home in addition and have someone watch me closely for 10 hours after my dental appointment to observe for side effects such as breathing or passing out.
