ATC classification:
Otoclean is a formula devised for treating impacted ear wax, the most common reason for reduced hearing, discomfort, and sometimes pain and dizziness. Formula contains cerumenolytics which not only softens and disperse the cerumen but also reduce the need for, or facilitate syringing in the ears.
Pharmacological action:
Paradichlorobenzene is a chlorinated aromatic hydrocarbon that is used in ear preparations as ear wax softener and helps in the removal of wax. Benzocaine is a local anesthetic that numbs the area where it is applied topically so as to provide a quick and effective pain relief. In otoclean ear drops it serves to numb the ear pain associated with the impacted ear wax. Chlorbutol and turpentine oil in Otoclean work as counterirritants providing analgesic relief.
Otoclean relieves ear ache, improves aural hygiene and facilitates hearing. It disperses the excess impacted cerumen by emulsifying it and facilitates easy removal of wax before ear examination. It also exerts antibacterial and anti-fungal actions.

  • Otoclean is indicated to relieve pain and itching from certain ear conditions such as middle ear inflammation with congestion and/or fluid build-up, swimmer’s ear and outer ear inflammation.
  • It is indicated for treating impacted ear wax which causes stuffed up sensation, dulled hearing and associated ear pain.
  • Used as prophylaxis to reduce the need for syringing/ facilitate syringing.

As directed by physician.

  • Instill 5-10 drops of Otoclean into the ear canal.
  • Insert cotton plug into the meatus and allow it to remain for about 15-30 minutes.
  • Clean the ear canal of the softened cerumen using a cotton swab.
  • Flush the ear canal gently with luke warm water using a soft rubber syringe avoiding excess pressure.
