Confusion methadone

True narcotic allergies are rare and should not be confused with pruritus associated with opiate use. Cross-sensitivity between morphine-like, meperidine-like, and methadone-like agents is unlikely. Therefore, when an individual is allergic to one drug in a chemical class of opioids, it is reasonable to select... 

Methadone is not a tranquilizer patients may react to problems and stresses with the same anxiety symptoms as others do. Do not confuse such symptoms with narcotic abstinence do not treat anxiety by increasing the methadone dose. 

After drugs are approved, the FDA tracks reports of errors due to drug name confusion and spreads the word to health professionals, along with recommendations for avoiding future problems. For example, the FDA has reported errors involving the inadvertent administration of methadone, a drug used to treat opiate dependence, rather than the intended Metadate ER (methylphenidate) for the treatment of attention-deficit/hyperactivity... 

Methadone 16 mg/day was effective in 29 patients with restless legs syndrome that had not responded to dopamine receptor agonists (9). Most (n = 17) were still taking methadone at follow-up and reported a 75% reduction in symptoms. Of 27 patients, 17 reported at least one adverse event while taking methadone, including constipation (n = 11), fatigue (n = 2), and insomnia, sedation, rash, reduced libido, confusion, and hypertension (one each). Five patients stopped treatment because of adverse events. 

It has X 2.5 the strength of Methadone Linctus, for cough (yellow or brown) they must not be confused. 

Ciprofloxacin, given to a patient who had been successfully treated with methadone for more than 6 years, caused profound sedation, confusion, and respiratory depression (73). This may have been due to inhibition of CYP1A2 and CYP3A4, two of the isozymes involved in the metabolism of methadone. 

Another of the important analgesics developed at the Hoechst Laboratories was Hoechst 10820 now known in the U.S.A. as methadone (8, 9). While methadone is an excellent analgesic, its numerous aliases have produced unnecessary confusion in the study of analgesics. 

An isolated case describes sedation, confusion and respiratoiy depression, which was attributed to the inhibition of methadone metabolism by ciprofloxacin. 

A woman taking methadone 140 mg daily for 6 years to manage pain due to chronic intestinal pseudo-obstruction was admitted to hospital because of a urinary tract infection and given ciprofloxacin 750 mg twice daily. Two days later she became sedated and confused. Ciprofloxacin was replaced with co-trimoxazole and the patient recovered within 48 hours. She was treated with ciprofloxacin for recurrent urinary-tract infections a further three times and on each occasion the patient bwame sedated, with her normal alertness regained on discontinuing ciprofloxacin. On the last oc-... 

In an open study in 21 opioid-tolerant patients with severe cancer pain who were switched to methadone, the switch was generally well tolerated only one patient required treatment withdrawal, because of respiratory depression [85 ]. Drowsiness was one of the most frequent adverse effects (in six patients) but it was of moderate intensity and responded to dosage reduction. Constipation was problematic in six. Other effects included nausea and vomiting (n = 2), sweating (n = 2), and confusion (n = 1).
