C10H14O3

Limited compatibility

Unsafe. Moderate/severe adverse effects. Compatible under certain circumstances. Follow-up recommended. Use safer alternative or discontinue breastfeeding from 5 to 7 T ½ . Read Commentary.

Mephenesin is a centrally acting skeletal muscle relaxant used for the symptomatic treatment of painful muscle spasm in some musculoskeletal diseases (Parkinson's, multiple sclerosis, cerebral palsy). Oral or topical cutaneous administration in several daily doses.

Since the last update we have not found published data on its excretion in breastmilk.

The few known pharmacokinetic data do not allow to predict its possible extraction in breast milk.

The potential side effects are serious (sedation, vomiting and respiratory arrest) and there is a risk of abuse and dependency. (Fanton 2007, Prescrire 2013)

The literature on this drug is scarce, and it is sold in few countries.

Can be used topically but avoid applying it on the breast.

Until more published data is known about this drug in relation to breastfeeding, known safer alternatives are preferable, especially during the neonatal period and in the event of prematurity.

Alternatives

  • Baclofen (Safe substance and/or breastfeeding is the best option.)
  • Carisoprodol (Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.)
  • Methocarbamol (Fairly safe. Mild or unlikely adverse effects. Compatible under certain circumstances. Follow-up recommended. Read Commentary.)

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.
