Neonatal alprazolam withdrawal--possible effects of breast feeding

Alprazolam: Good for Some, Not Good for All!

BACKGROUND

Although alprazolam is approved only for use in panic disorder and generalized anxiety disorder, it is used for numerous other conditions, not only by psychiatrists but also by medical professionals in general. This commentary critically analyzes the use of alprazolam.

METHODS

A narrative review approach was adopted, using relevant articles and textbooks, to compile pertinent literature for the aforementioned topic.

RESULTS

Among all its adverse reactions, the most bothersome concern about the use of alprazolam is its potential for abuse and dependence. This can be attributed to certain unique pharmacokinetic and pharmacodynamic properties of this benzodiazepine. Also, the withdrawal triggered by use of alprazolam is challenging to treat. Alternate pharmacological and non-pharmacological strategies for use in anxiety and insomnia are available, which might be safer than alprazolam. Also, policy changes can serve as an answer to curb alprazolam abuse to some extent. Alprazolam might still be a good choice for individuals who do not have a history of abuse of other substances, with adequate psychoeducation and close monitoring of their usage pattern.

CONCLUSION

There is a need to reconsider the need for long-term use of benzodiazepines in general, and alprazolam in particular. However, they still might be an appropriate choice in individuals where abuse and dependence are less likely.

Medications and Breast-Feeding: A Guide for Pharmacists, Pharmacy Technicians, and other Healthcare Professionals Part III

Objective:

To provide a guide for practicing pharmacists, pharmacy technicians, and other healthcare professionals so that they are able to counsel and advise breast-feeding mothers and fellow healthcare professionals on the safety and use of antiinfectives, vaccines, antiepileptics, benzodiazepines, psychotherapeutic drugs, and radiopharmaceuticals during breast-feeding.

Data Sources:

Primary texts used by the breast-feeding community ( Medications and Mothers' Milk, Drugs in Pregnancy and Lactation, Drugs and Human Lactation) were searched, as well as Micromedex, MEDLINE, PubMed, EMBASE, and EMBASE2 (1984–February 2004).

Study Selection/Data Extraction:

Multiple sources were used wherever available to validate the data, and primary articles were used to verify all tertiary source information. Search terms included breast-feeding, lactation, nursing, and medications, as well as specific drug names.

Data Synthesis:

Concerns regarding medication use during breast-feeding have caused mothers to either discontinue nursing or not take necessary medications. Complete avoidance of medications or cessation of breast-feeding is often unnecessary. Although there are drugs that can be harmful to nursing infants, breast-milk concentrations of most drugs are insufficient to cause any harm.

Conclusions:

Having objective and reliable information on medications enables pharmacists, pharmacy technicians, other healthcare providers, and mothers to make educated decisions regarding drug therapy and breast-feeding.

Use of common migraine treatments in breast-feeding women: a summary of recommendations

BACKGROUND

Breast-feeding has important health and emotional benefits for both mother and infant, and should be encouraged. While there are some data to suggest migraine may improve during breast-feeding, more than half of women experience migraine recurrence with 1 month of delivery. Thus, a thorough knowledge base of the safety and recommended use of common acute and preventive migraine drugs during breast-feeding is vital to clinicians treating migraine sufferers. Choice of treatment should take into account the balance of benefit and risk of medication. For some of the medications commonly used during breast-feeding, there is not good evidence about benefits.

METHODS

A list of commonly used migraine medications was agreed upon by the 6 authors, who treat migraine and other headaches on a regular basis and are members of the Women's Special Interest Section of the American Headache Society. Each medication was researched by the first author utilizing widely accepted data sources, such as the American Academy of Pediatrics publication "The Transfer of Drugs and Other Chemicals Into Human Milk; Thomas Hale's manual Medications and Mothers Milk; Briggs, Freeman, and Yaffe's reference book Drugs in Pregnancy and Lactation; and the National Library of Medicine's Drugs and Lactation Database (LactMed) - a peer-reviewed and fully referenced database available online.

RESULTS

Many commonly used migraine medications may be compatible with breast-feeding based on expert recommendations. Ibuprofen, diclofenac, and eletriptan are among acute medications with low levels in breast milk, but studies of triptans are limited. Toxicity is a concern with aspirin due to an association with Reye's syndrome; sedation or apnea is a concern with opioids. Finally, preventive medications not recommended include zonisamide, atenolol, and tizanidine.

CONCLUSIONS

Several excellent resources are available for clinicians making treatment decisions in breast-feeding women. Clinicians treating migraine should discuss both acute and preventive treatment options shortly before and within a few months after delivery, keeping in mind the clinical features of the individual patient, and in consultation with their obstetrician and pediatrician. An awareness of the pharmacological data that are currently available and how to access that data may be helpful in making treatment decisions in this population.

Confirmation of gestational exposure to alprazolam by analysis of biological matrices in a newborn with neonatal sepsis

BACKGROUND

Different biological matrices are suitable for drug testing in newborns presenting with an acute withdrawal syndrome.

CASE REPORT

The newborn of a mother reporting alprazolam use during pregnancy presented with respiratory distress and clinical features consistent with neonatal withdrawal syndrome or neonatal sepsis of vertical transmission. Alprazolam and its main metabolite (alpha-hydroxyalprazolam) were detected in cord serum, neonatal urine and also in neonatal hair, meconium and placenta, accounting for both acute and chronic exposure to this benzodiazepine during intrauterine life. At the same time, the clinical diagnosis of neonatal sepsis was confirmed by isolation of Streptococcus agalactiae from otic cultures. The infant received oxygen therapy and antibiotic treatment and recovered completely at the age of 11 days. Although no congenital anomalies or behavioral alterations were diagnosed during hospitalization, periodic follow-ups were requested to check for potential long-term effects of prenatal exposure to alprazolam.

Adverse drug reactions in breastfed infants: less than imagined

Medication use during breastfeeding shortens the duration of breastfeeding often because of overly cautious information given by healthcare providers. No comprehensive review of the literature on infant adverse reactions from drugs in breastmilk has been published. All published studies and case reports on adverse events in infants caused by medications (excluding drugs of abuse) in breastmilk were identified and analyzed. Of 100 case reports evaluated, none were considered to be "definite" using a standard ranking scale; 47% were "probable" and 53% were "possible." Drugs with central nervous system activity accounted for half of all reports. All 3 reported fatalities involved central nervous system depressants, but each had extenuating circumstances. At least 63% of reported cases were in neonates and 78% were in infants 2 months or younger; only 4% of adverse reactions occurred in infants older than 6 months of age. Published studies expand on and generally reinforce the analysis of case reports. By taking a few simple precautions in drug selection and considering the infant's age, breastfeeding rarely needs to be discouraged or discontinued when a mother needs drug therapy.
