Somnol

Venlafaxine (48) is a stmcturaHy novel phenylethylamine derivative that strongly inhibits both noradrenaline and serotonin reuptake. It lacks anticholinergic, antihistaminergic, and antiadrenergic side effects. As compared to placebo, most common adverse events are nausea, somnolence, dizziness, dry mouth, and sweating. Venlafaxine-treated patients also experienced more headaches and nausea, but less dry mouth, dizziness, and tremor than patients treated with comparator antidepressants. 

The unusual physical complaints and findings in workers overexposed to teUurium include somnolence, anorexia, nausea, perspiration, a metallic taste in the mouth and garlic-like odor on the breath (48). The unpleasant odor, attributed to the formation of dimethyl teUuride, has not been associated with any adverse health symptoms. Tellurium compounds and metaboUc products have been identified in exhaled breath, sweat, urine, and feces. Elimination is relatively slow and continuous exposure may result in some accumulation. No definite pathological effects have been observed beyond the physical complaints outlined. Unlike selenium, teUurium has not been proved to be an essential biological trace element. 

CNS (Central Nervous System). The brain and the spinal cord. CNS stimulant. A drug that counteracts fatigue and somnolence. 

Delirium, e.g. post-narcotic delirium, somnolence or coma, is a common complication involving dementia, with fluctuating attention and consciousness and considerable morbidity. It is not always reversible and there is no specific treatment. Some of the accompanying central cholinergic syndromes can be reversed by ChEIs.

The most common adverse reaction associated with phenobarbital is sedation, which can range from mild sleepiness or drowsiness to somnolence. These dru > may also cause nausea, vomiting, constipation, bradycardia, hypoventilation, skin rash, headache fever, and diarrhea Agitation, rather than sedation, may occur in some patients. Some of these adverse effects may be reduced or eliminated as therapy continues. Occasionally, a slight dosage reduction, without reducing the ability of the drug to control the seizures, will reduce or eliminate some of these adverse reactions. 

The adverse reactions most often associated with the administration of the COMT inhibitors include disorientation, confusion, light-headedness, dizziness, dyskinesias, hyperkinesias, nausea, vomiting, hallucinations, and fever. Other adverse reactions are orthostatic hypotension, sleep disorders, excessive dreaming, somnolence, and muscle cramps.

MANAGING LACTIC ACIDOSIS. When taking metformin, the patient is at risk for lactic acidosis. The nurse monitors die patient for symptoms of lactic acidosis, which include unexplained hyperventilation, myalgia, malaise, gastrointestinal symptoms, or unusual somnolence If the patient experiences these symptoms, the nurse should contact the primary care provider at once. Elevated blood lactate levels of greater than 5 mmol/L are associated with lactic acidosis and should be reported immediately. Once a patient s diabetes is stabilized on metformin therapy, the adverse GI reactions that often occur at the beginning of such therapy are unlikely to be related to the drug therapy. A later occurrence of GI symptoms is more likely to be related to lactic acidosis or other serious disease. 

Metformin—there is a risk of lactic acidosis when using this drug. Discontinue die drug therapy and notify the health care provider immediately if any of the following should occur respiratory distress, muscular aches, unusual somnolence, unexplained malaise, or nonspecific abdominal distress.
