Orphenadrine

Low Risk

Moderately safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.

Anti-muscarinic analogue agent similar to Diphenhydramine with no sedative effect. Used for the treatment of muscle spasms and Parkinson Disease.

At latest update, relevant published data on excretion into breast milk were not found.

Its pharmacokinetics (moderately high molecular weight and high protein-binding capacity) makes excretion into breast milk in significant amount be unlikely.

Until more data on this medication is available, safer alternative drugs are preferred especially in premature babies or during the neonatal period.

Whenever used while breastfeeding take the lowest dose as possible along with a follow-up for somnolence and troubles of the infant with feeding.

It is not commercially available in Spain.

Alternatives

  • Baclofen ( Safe. Compatible. Minimal risk for breastfeeding and infant.)
  • Methocarbamol (Moderately safe. Probably compatible. Mild risk possible. Follow up recommended. Read the Comment.)

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.

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
