Definition

Merthiolate overdose is poisoning from an overdose of merthiolate.

Poisonous Ingredient

Thimerosal

Where Found

  • Merthiolate
  • Some eye drops
  • Some nasal drops

Symptoms

Home Treatment

Thimerosal is poorly absorbed from the intestinal tract and serious poisoning is unlikely. However, if you are concerned about a possible overdose, contact your local poison control center for advice.

Before Calling Emergency

Determine the following:

  • The patient's age, weight, and condition
  • The name of the product (ingredients and strengths if known)
  • When it was swallowed
  • The amount swallowed

Poison Control, or a local emergency number

If you are concerned about a Merthiolate overdose or poisoning, seek medical care at your nearest emergency room. See poison control centers for the national telephone number. Take the container with you to the emergency room.

What to expect at the emergency room

Some or all of the following may be performed or given:

  • Activated charcoal
  • A cathartic (a medication used to evacuate the bowels)
  • An antidote
  • Treatment of the symptoms

Expectations (prognosis)

Because a serious poisoning is unlikely, full recovery is very probable.
