Digoxin

May reduce rate and extent of digoxin absorption; this may be offset by decreased digoxin metabolism.

Methotrexate

Decreased absorption of methotrexate.

Neuromuscular blockers

Increased action of both depolarizing and nondepolarizing neuromuscular blocking agents, may prolong need for respiratory support.

Neurotoxic, nephrotoxic, or ototoxic medications (eg, polypeptide antibiotics)

Neurotoxicity

Manifests as both auditory and vestibular ototoxicity, and primarily occurs in patients with pre-existing renal damage or with prolonged therapy. Partial or total irreversible deafness may continue to develop after drug is stopped. Other features of neurotoxicity include paresthesias, twitching, and seizures.

Nephrotoxicity

Usually reversible.

Paromomycin is teratogenic in pregnancy. Closely monitor renal and eighth nerve function in patients with suspected renal function impairment. Monitor peak and trough concentrations. Renal function impairment requires dosage adjustments.

Pregnancy

Category D .

Lactation

Excreted in breast milk.

Superinfection

Prolonged or repeated therapy may result in bacterial or fungal overgrowth of nonsusceptible organisms and secondary infections.

Muscular disorders

Patients with muscular disorders such as myasthenia gravis or parkinsonism may have worsening of their disease because of potential effect of aminoglycosides on neuromuscular junction.

Overdosage

Symptoms

Neurotoxicity, nephrotoxicity, ototoxicity.

Patient Information

  • Stress to patient the importance of taking full course of therapy.
  • Emphasize to patient the importance of personal hygiene, especially handwashing.
