Precautions & Warnings

  • Verify the specific type of intestinal worm infection with a healthcare provider.

Avoid Interactions

Avoid

  • Anthelmintics with overlapping mechanisms that could increase the risk of adverse reactions.

Use with caution

  • Any drug that may cause liver strain in patients with pre‑existing hepatic conditions.
