If the delirium involves alcohol withdrawal, benzodiazepine withdrawal, or contraindications to antipsychotics (e.g. in Parkinsons disease or neuroleptic malignant syndrome), then benzodiazepines are recommended. Similarly, people with dementia with Lewy bodies may have significant side effects to antipsychotics, and should either be treated with a none or small doses of benzodiazepines.The antidepressant trazodone is occasionally used in the treatment of delirium, but it carries a risk of over-sedation, and its use has not been well studied.For adults with delirium that are in the ICU, medications are used commonly to improve the symptoms. Dexmedetomidine may shorten the length of the delirium in adults who are critically ill and rivastigmine is not suggested. For adults with delirium who are near the end of their life (on palliative care) high quality evidence to support or refute the use of most medications to treat delirium is not available. Low quality evidence indicates that the antipsychotic medications risperidone or haloperidol may make the delirium slightly worse in people who are terminially ill, when compared to a placebo treatment. There is also moderate to low quality evidence to suggest that haloperidol and risperidone may be associated with a slight increase in side effects, specifically extrapyramidol symptoms, if the person near the end of their life has delirium that is mild to moderate in severity. Prognosis
There is substantial evidence that delirium results in long-term poor outcomes in older persons admitted to hospital.
Varicella - Small ulcers on the back of the oral cavity and vesicular lesions on the scalp and trunk are common for Varicella. It is ruled out as the location of the infections are unilateral, unlike herpetic gingivostomatitis which is bilateral. Treatment
The aim of treatment is mostly supportive such as pain control, duration of symptoms, viral shedding and in some cases, preventing outbreak. Antibiotics are rarely prescribed to treat bacterial superinfection of oral lesions. Antiviral drugs are used to treat herpetic gingivostomatitis such as aciclovir, valaciclovir, famciclovir, and in resistance cases foscarnet can be used. Treatment does not prevent recurrence. Most individuals who are immunocompetent will fully recover from recurrent herpes labialis in 7 to 14 days. However treatment with antipyretics, oral anaesthetics and analgesics is often needed. In severe cases of herpetic gingivostomatitis, mouth rinses are useful in relieving oral discomfort. These contain topical anaesthetic agents such as lidocaine and diphenhydramine as well as coating agents such as magnesium-containing antacids. In order to prevent dehydration, oral fluid intake is encouraged. Other treatment options include good oral hygiene and gentle debridement of the mouth. A number of precautions can be taken to reduce the risk of infection of HSV including;

Avoid saliva exchange with those with active HSV
Avoid direct contact with active lesions (if contact occurred, ensure area is washed adequately)
Those with recurrent HSV can apply sunscreen lip balm as ultraviolet light is a stimulus for the infection
