5. Risks & Inconveniences. Virtually all forms of medication, including oral sedatives, have some risks and possible side effects. Pain medication or sedative agents can, among other things, alter your judgment and work performance, and you should plan accordingly. With sedation, you may experience relaxation or drowsiness, a reduced sense of fear or anxiety, increased tolerance to discomfort, an altered perception of time, tingling sensations, giddiness or lightheadedness, clumsiness, or unsteadiness, nausea, hallucinations or dreams. Less common side effects include blurred vision, memory loss (which many people deem desirable for dental treatment), or “rebound insomnia'” for several days. Rare side effects include agitation, behavior changes, convulsions, hypotension, skin rash or itching, sore throat, fever, chills, unusual tiredness, increased heart rate, hyperactivity or weakness may occur. If you experience any unpleasant affects, before or after your procedure, please inform the doctor or assistant as soon as possible. There is also a chance of an allergic reaction to the sedation medication which may include: itching, hives, redness of the skin, swelling or sweating. If you notice any of the symptoms you must contact your dentist or other medical professionals immediately.
