Fair response with partial improvement was noted in 37% of male patients and 34% of female patients. No response was reported in 10% of male and 8% of female IBS patients. There were few side effects noted with 8% reporting dry mouth. Dosages were reduced in patients who reported drowsiness (10%) as well as 1 patient who reported visual disturbance. Otherwise, the formulation was well tolerated. Donnatal also is a common component of a GI cocktail used in emergency rooms. In 1976, Donnatal was one of the 25 most widely prescribed drugs in the U.S. It has since been displaced by H2 antagonists and proton pump inhibitors, which are more effective and lack many of the adverse effects of phenobarbital.A four-week multicenter, randomized placebo-controlled trial by Turner et al. compared Donnatal® tablets (hyoscyamine sulfate - 0.1037 mg; atropine sulfate - 0.0194 mg; scopolamine hydrobromide - 0.0065 mg and phenobarbital - 16.2 mg) to belladonna alkaloids alone (hyoscyamine sulfate - 0.1037 mg; atropine sulfate - 0.0194 mg; scopolamine hydrobromide - 0.0065 mg), phenobarbital alone (16.2 mg) and placebo. The intent-to-treat population of 204 IBS patients was evaluated for pain (cramping), nighttime and daytime pain severity, bowel movement frequency, and with a clinician global evaluation of improvement in response to treatment. The response for improvement of pain was mixed for all groups after 1 day.
Such symptoms include:
Increased thirst
Increased urination, especially waking up in the night to urinate
Tiredness and fatigue
Blurred vision
Slow healing of wounds
Altered sensation, such as numbness or tingling, particularly of the hands and feet
Recurrent, and difficult to clear infections, particularly of the urinary tract

Risk factors
As impaired fasting glucose is considered a precursor condition for type 2 diabetes, it shares the same environmental and genetic risk factors. Diagnosis
Different organisations use slightly differing levels before classifying a persons fasting blood glucose as "impaired", with the American Diabetes Association using a lower cutoff in its criteria than the World Health Organization. The upper limits remain the same, as fasting levels above this are almost universally accepted as indicative of full diabetes:

WHO criteria: fasting plasma glucose level from 6.1 mmol/L (110 mg/dL) to 6.9 mmol/L (125 mg/dL). ADA criteria: fasting plasma glucose level from 5.6 mmol/L (100 mg/dL) to 6.9 mmol/L (125 mg/dL). Prevention
The guidelines for preventing impaired fasting glucose are the same as those given for preventing type 2 diabetes in general. If these are adhered to, the progression to clinical diabetes can be slowed or halted. In some cases, a complete reversal of IFG can be achieved. Certain risk factors, such as being of Afro-Caribbean or South Asian ethnicity, as well as increasing age, are unavoidable, and such individuals may be advised to follow these guidelines, as well as monitor their blood glucose levels, more closely.
