In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response.

These individuals convert tramadol into its active metabolite, The concomitant use of tramadol hydrochloride tablets with all cytochrome P450 2D6 inhibitors (e.g., amiodarone, quinidine) may result in an increase in tramadol plasma levels and a decrease in the levels of the active metabolite, M1. Evaluation of patients with hypertension or myocardial infarction should always include assessment of renal function.The frequency estimates in the following table were derived from controlled studies in hypertensive patients in which adverse reactions were either volunteered by the patient (US studies) or elicited, eg, by checklist (foreign studies). Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.With the prolonged half-life in these conditions, achievement of steady-state is delayed, so that it may take several days for elevated plasma concentrations to develop.All patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.Prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects.Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful, or potentially harmful, consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal.

(SeeBradycardia and heart block can occur and the left ventricular end diastolic pressure can rise when beta-blockers are administered with verapamil or diltiazem. Additionally, common effects associated with overdosage of any beta-adrenergic blocking agent and which might also be expected in Tenormin overdose are congestive heart failure, hypotension, bronchospasm and/or hypoglycemia.Treatment of overdose should be directed to the removal of any unabsorbed drug by induced emesis, gastric lavage, or administration of activated charcoal. (See Patients with coronary artery disease, who are being treated with Tenormin, should be advised against abrupt discontinuation of therapy.

The remainder is excreted either as unidentified or as unextractable metabolites.Metabolism of tramadol and is reduced in patients with severe hepatic impairment based on a study in patients with advanced cirrhosis of the liver, resulting in both a larger area under the concentration time curve for tramadol and longer tramadol and M1 elimination half-lives (13 hrs. Keep this medicine in a safe place to prevent theft, misuse, or abuse.

0 The mean ratio of serum tramadol in the umbilical veins compared to maternal veins was 0.83 for 40 women given tramadol during labor.The effect of tramadol hydrochloride tablets, if any, on the later growth, development, and functional maturation of the child is unknown.Tramadol has been shown to be embryotoxic and fetotoxic in mice, (120 mg/kg), rats (25 mg/kg) and rabbits (75 mg/kg) at maternally toxic dosages, but was not teratogenic at these dose levels. The clinical significance of this difference is unknown.The formation of the active metabolite, M1, is mediated by CYP2D6, a polymorphic enzyme. The dose range of Tenormin is narrow and increasing the dose beyond 100 mg once daily is not associated with increased antihypertensive effect.

You may report side effects to Health Canada at 1-866-234-2345.This drug may make you dizzy or drowsy. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised.Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.Tramadol hydrochloride tablets are intended for oral use only. (See Catecholamine-depleting drugs (eg, reserpine) may have an additive effect when given with beta-blocking agents.
