4.First-aid measures
4.1 Description of necessary first-aid measures
General advice
Consult a physician. Show this safety data sheet to the doctor in attendance.
If inhaled
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
In case of skin contact
Wash off with soap and plenty of water. Consult a physician.
In case of eye contact
Rinse thoroughly with plenty of water for at least 15 minutes and consult a physician.
If swallowed
Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
4.2 Most important symptoms/effects, acute and delayed
no data available
4.3 Indication of immediate medical attention and special treatment needed, if necessary
Emergency and supportive measures: Maintain an open airway and assist ventilation if necessary. Treat coma, seizures, hyperthermia, and atypical ventricular tachycardia if they occur. Monitor the patient for at least 6 to 8 hours after ingestion. Specific drugs and antidotes: There is no specific antidote for antihistamine overdose. As for anticholinergic poisoning, physostigmine has been used for treatment of severe delirium or tachycardia. However because antihistamine overdose carry a greater risk for seizures physostigmine is not recommended routinely. Sodium bicarbonate may be useful for myocardial depression ... . Decontamination: Administer activated charcoal orally if conditions are appropriate. Gastric lavage is not necessary after small to moderate ingestions if activated charcoal can be given promptly. Because of slowed gastrointestinal motility, gut decontamination procedures may be helpful even in late-presenting patients. Enhanced elimination: Hemodialysis, hemoperfusion, peritoneal dialysis, and repeat dose activated charcoal are not effective in removing antihistamines. /Antihistamines/

- Toxicity to daphnia and other aquatic invertebrates: no data available
- Toxicity to algae: no data available
- Toxicity to microorganisms: no data available
12.2 Persistence and degradability
no data available
12.3 Bioaccumulative potential
The pKa of diphenhydramine is 8.98(1), indicating that diphenhydramine will exist almost entirely in the cation form at pH values of 5 to 9 and, therefore, bioconcentration in fish is not expected to be an important fate process(SRC).
12.4 Mobility in soil
The Koc of diphenhydramine is estimated as 380(SRC), using a log Kow of 3.27(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diphenhydramine is expected to have moderate mobility in soil. Using a soil column study, diphenhydramine, present at 0.112 ug/L in added treated effluent, was detected at 0.081 ug/L in the outflow 23 days later(4). The pKa of diphenhydramine is 8.98(5), indicating that this compound will exist partially in the cation form in the environment and cations generally adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(6).
12.5 Other adverse effects
no data available
13.Disposal considerations
13.1 Disposal methods
Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
