Drug Interactions between dihydrocodeine / phenylephrine and hyaluronidase

GENERALLY AVOID: Hyaluronidase may enhance the absorption and dispersion of dopamine and/or other injectable alpha agonist drugs, resulting in cardiovascular effects such as increased blood pressure, increased vascular resistance and other alpha adrenergic-mediated adverse effects. Hyaluronidase is a dispersion agent, that can increase the permeability of connective tissue through the hydrolysis of hyaluronic acid. There are no clinical data available for this interaction.

MANAGEMENT: The manufacturer of hyaluronidase recommends avoiding the use of hyaluronidase to enhance the absorption and dispersion of dopamine and/or alpha agonist drugs. Some authorities consider this particular use of hyaluronidase as contraindicated. However, hyaluronidase used for other indications, may be administered to patients receiving dopamine and/or alpha agonist drugs. Consultation with product labeling and local or institutional guidelines may be appropriate for further recommendations.
