Use with caution in patients with respiratory, hepatic or renal dysfunction,

therapy should be observed; some preparations contain sulfites which may cause
allergic reactions; infants <3 months of age are more susceptible to
respiratory depression, use with caution and generally in reduced doses in this
age group; tolerance or drug dependence may result from extended
use |

Patient
Information |
|
Take exactly as directed; do not increase dosage. May cause dependence with
prolonged or excessive use. Avoid alcohol and all other prescription and OTC
medications that may cause sedation (sleeping medications, some cough/cold
remedies, antihistamines, etc). You may experience drowsiness, dizziness, or
impaired judgment (use caution when driving or engaging in tasks that require
alertness until response to drug is known) or postural hypotension (use caution
when rising from sitting or lying position or when climbing stairs). You may
experience nausea or loss of appetite (frequent small meals may help) or
constipation (a laxative may be necessary). Report unresolved nausea, vomiting,
respiratory difficulty (shortness of breath or decreased respirations), chest
pain, or palpitations. Breast-feeding precautions: If nursing, take
immediately after feeding or 4-6 hour before next feeding. |
