Symptoms

In cases of accidental ingestion, acute intoxication symptoms may be observed such as nausea, vomiting and irritation of the buccal, oesophageal and gastric mucosa. Rare cases of loss of consciousness and seizure were reported. General measures to eliminate the drug and reduce its absorption should be undertaken.

The symptoms usually disappear following the discontinuation of the drug, but in severe cases treatment with methylene blue may be considered.
