Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Alcohol and other medications that cause drowsiness: People taking this medication should not combine it with alcohol and avoid combining it with other medications, such as narcotic pain relievers, that cause drowsiness. Doing so can cause additive drowsiness and reduced breathing as well as other side effects, which can be dangerous and possibly fatal.
Dependence and withdrawal: Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with benzodiazepines such as S 901 pill. Severe withdrawal symptoms may be experienced if the dose is significantly reduced or suddenly discontinued. These symptoms include seizures, irritability, nervousness, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, memory impairment, headache, muscle pain, extreme anxiety, tension, restlessness, and confusion. Reducing the dose gradually, under medical supervision, can help prevent or decrease these withdrawal symptoms.
Because the treatment of panic disorder often requires the use of average daily doses of S 901 pill above 3 mg, the risk of dependence among people with panic disorder may be higher than that among those treated for less severe anxiety.
Drowsiness/reduced alertness: S 901 pill may affect the mental or physical abilities needed to drive or operate machinery. Do not engage in activities requiring mental alertness, judgment, and physical coordination until you have established how S 901 pill affects you. Alcohol can increase the drowsiness effects of S 901 pill and should be avoided.
Kidney function: Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have kidney problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Mood changes: Anxiety disorders are often associated with mood changes, such as depression, mania, or ideas of suicide or self-harm. If you have depression or a history of depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you experience symptoms of depression such as poor concentration, changes in weight, changes in sleep, decreased interest in activities, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.

Breast-feeding: S 901 pill may pass into breast milk. If you are a breast-feeding mother and are taking S 901 pill, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children and adolescents: The safety and efficacy of S 901 pill for children and adolescents under 18 years of age have not been established.
