| Gesundheitsgefahren | SYMPTOMS: Symptoms of exposure to this compound include excitement, sleepiness, convulsions and rigidity. Other symptoms include leukopenia, agranulocytosis, drowsiness, confusion and stupor. Acute transitory myopia may occur. Central nervous system effects may also occur. It may cause an increase in blood pressure, mild hypotension, jaundice, extra-pyramidal reactions and photosensitivity. It may also cause dizziness, central nervous system depression, vomiting, local anesthesia, abdominal pain, diarrhea and dryness of the mouth, throat and nose. Symptoms of exposure to this type of compound include muscular weakness, tachycardia, nausea, sedation, tinnitus, lassitude, incoordination, fatigue, blurred vision, diplopia, euphoria, nervousness, insomnia, tremors, loss of appetite, epigastric distress, constipation, cough, urinary retention or frequency, dysuria, palpitation, headache, tightness of the chest, tingling, heaviness and weakness of the hands, allergic dermatitis, fever, hemolytic anemia (rare), fixed and dilated pupils, and flushing. In children, exposure can cause hallucinations, excitement, ataxia, incoordination, athetosis and convulsions. |

| Reactivity Profile | PROMETHAZINE HYDROCHLORIDE is sensitive to light. In aqueous solution, it is degraded by heat and light (more rapidly in air or oxygen). Incompatible with alkalis and alkaline solutions such as those of aminophylline, soluble barbiturates and phenytoin sodium. Iron(III) and copper(III) accelerate the degradation (NTP, 1992). |
|---|
| Air and Water Reactions | Slowly oxidizes in air, acquiring a blue color. Also turns blue on exposure to moisture. Water soluble. |

| Erste Hilfe | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. If symptoms (such as redness or irritation) develop, immediately transport the victim to a hospital. |
|---|
| Freisetung ohne Brand | SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. |
|---|
| Personal Protective Equipment (PPE) | RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. |

| Expositionspfade | On average, 88% of a promethazine dose is absorbed after oral administrationhowever, the absolute bioavailability is only 25% because of first-pass clearance. |
|---|
| Toxizitätsübersicht | Like other H1-antagonists, promethazine competes with free histamine for binding at H1-receptor sites in the GI tract, uterus, large blood vessels, and bronchial muscle. The relief of nausea appears to be related to central anticholinergic actions and may implicate activity on the medullary chemoreceptor trigger zone. |
|---|
| Signs and Symptoms | Symptoms of overdose include mild depression of the central nervous system and cardiovascular system to profound hypotension, respiratory depression, unconsciousness, and sudden death. Other reported reactions include hyperreflexia, hypertonia, ataxia, athetosis, and extensor-plantar reflexes (Babinski reflex). |
