Pridinol Mesilate

High Risk

Poorly safe. Evaluate carefully. Use safer alternative or interrupt breastfeeding 3 to 7 T ½ (elimination half-lives). Read the Comment.

Centrally acting muscle relaxant with anticholinergic effects. Indicated for central and peripheral muscle spasms, lumbar pain, torticollis and generalized muscle pain. Oral administration in three daily doses.

At last update no published on excretion in breast milk data were found.

There are hardly any pharmacokinetic data in humans to predict its possible excretion in breast milk.

Its anticholinergic effect has a theoretical risk of inhibiting lactation especially during the early postpartum weeks.

Until more data about this drug regarding breastfeeding is available, safer known alternatives should be of choice, especially in the neonatal period and in case of prematurity.

If administered during breastfeeding, use small doses and monitor drowsiness and adequate feeding of the infants.

Not to be confused with the trademark Pridinol, which in some countries corresponds to Terfenadine.

Alternatives

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