Primary Physical and Health Hazards: Not hazardous if intact.  Corrosive (eyes).  Nervous System and Liver Effects.  

Caution Statement: Intact Duloxetine Hydrochloride Capsules are not considered to be a health hazard. The contents of Duloxetine Hydrochloride Capsules may cause burns or permanent tissue damage to the eyes. Effects of exposure may include dizziness, nausea, drowsiness, fatigue, and liver effects.  

Routes of Entry: Inhalation and skin contact.  

Effects of Overexposure: Capsules are intended for human consumption under guidance of a physician.  Intact capsules are not considered hazardous under normal handling procedures.  Adverse events commonly observed during therapeutic administration include nausea, dry mouth, constipation, decreased appetite, fatigue, dizziness, drowsiness, headache, insomnia, and increased sweating.

Duloxetine, the active ingredient, is harmful if swallowed, may cause burns or permanent tissue damage to the eyes, and may be slightly irritating to the skin.  In animal studies, the major signs of overdose toxicity would be related to the central nervous (tremors, clonic convulsions, ataxia) and gastrointestinal (emesis, decreased appetite) systems.  Liver effects have been reported in long-term animal studies at high doses.  

Medical Conditions Aggravated by Exposure: None known.  

Duloxetine hydrochloride - Not listed by IARC, NTP, ACGIH, or OSHA.  

Section 4 - First Aid Measures

Eyes: Hold eyelids open and flush with a steady, gentle stream of water for 15 minutes.  See an ophthalmologist (eye doctor) or other physician immediately.  

Skin: Remove contaminated clothing and clean before reuse.  Wash all exposed areas of skin with plenty of soap and water.  Get medical attention if irritation develops.  

Inhalation: Move individual to fresh air.  Get medical attention if breathing difficulty occurs.  If not breathing, provide artificial respiration assistance (mouth-to-mouth) and call a physician immediately.  

Ingestion: Do not induce vomiting.  Call a physician or poison control center.  If available, administer activated charcoal (6-8 heaping teaspoons) with two to three glasses of water.  Do not give anything by mouth to an unconscious person.  Immediately transport to a medical care facility and see a physician.  

Notes to Physician:
Duloxetine - No specific antidote is known. An airway should be established. Monitoring of cardiac and vital signs is recommended, along with appropriate symptomatic and supportive measures. Gastric lavage may be indicated if performed soon after ingestion or in symptomatic patients. Activated charcoal may be useful in limiting absorption. Duloxetine has a large volume of distribution and forced diuresis, hemoperfusion, and exchange perfusion are unlikely to be beneficial.   

Section 5 - Fire Fighting Measures

Flash Point: No applicable information found
UEL: No applicable information found
LEL: No applicable information found

Extinguishing Media: Use water, carbon dioxide, dry chemical, foam, or Halon.  

Unusual Fire and Explosion Hazards: As a finely divided material, may form dust mixtures in air which could explode if subjected to an ignition source.  

Hazardous Combustion Products: May emit toxic fumes when exposed to heat or fire.  

Section 6 - Accidental Release Measures

The following are recommended for manufacturing or other situations where exposure to the contents may occur.  

Spills: Vacuum material with appropriate dust collection filter in place.  Be aware of potential for dust explosion when using electrical equipment.��If vacuum is not available, lightly mist material and remove by sweeping or wet wiping.  Wear protective equipment, including eye protection, to avoid exposure (see Section 8 for specific handling precautions).  

Section 7 - Handling and Storage

Storage Conditions: Controlled Room Temperature:  15 to 30 C (59 to 86 F).  

Section 8 - Exposure Controls / Personal Protection

See Section 2 for Exposure Guideline information.  

  Intact capsules are not considered hazardous under normal handling procedures and protective equipment is not required.  The following are recommended for manufacturing or other situations where exposure to contents may occur.  

Respiratory Protection: Use an approved respirator.  

Eye Protection: Chemical goggles and/or face shield.  

Ventilation: Laboratory fume hood or local exhaust ventilation.  

Other Protective Equipment: Chemical-resistant gloves and body covering to minimize skin contact.  If handled in a ventilated enclosure, as in a laboratory setting, respirator and goggles or face shield may not be required.  Safety glasses are always required.  

Additional Exposure Precautions: In production settings, airline-supplied, hood-type respirators are preferred.  Shower and change clothing if skin contact occurs.

Section 11 - Toxicological Information

Acute Exposure
Data for the active ingredient, duloxetine hydrochloride, are reported.  

Duloxetine hydrochloride - Rat, median lethal dose 491 mg/kg for males and 279 mg/kg for females, tremors, convulsions.
Dog, 100 mg/kg, no deaths, reduced activity, slow pupillary response, intermittent tremors, rigidity.  

Duloxetine hydrochloride - Rabbit, 1000 mg/kg, no deaths or toxicity.  

Inhalation: No applicable information found.  

Skin Contact:
Duloxetine hydrochloride - Rabbit, slight irritant  

Eye Contact:
Duloxetine hydrochloride - Rabbit, corrosive  

Chronic Exposure
Data for the active ingredient, duloxetine hydrochloride, are reported.  

Target Organ Effects:
Duloxetine hydrochloride - Dilation of the pupil and slow pupillary light response reported in dogs administered 3, 10, and 30 mg/kg orally for 1 year.  Slight increase in liver enzymes reported in the mid- and high-dose animals.  Liver effects (tissue changes, enzyme induction) reported in rats administered up to 0.08% in diet (47 mg/kg/day) for 6 months.  

Duloxetine - Reproductive performance was not affected in male rats (45 mg/kg/day). In female rats (45 mg/kg/day), reproductive toxicity was demonstrated by a decrease in maternal food consumption and body weight, estrous cycle disruption, depressions in live birth indices and progeny survival, and progeny growth retardation. The no-observed- effect level (NOEL) for maternal toxicity, reproductive toxicity, and developmental toxicity in the female fertility study was 10 mg/kg/day. There was no evidence of teratogenicity in animal studies. Duloxetine and/or its metabolites are excreted into the milk of lactating rats.   

Duloxetine hydrochloride - Guinea pig, negative in active systemic anaphylaxis and passive cutaneous anaphylaxis tests.  

Duloxetine - Demonstrated no mutagenic potential in a battery of in vitro and in vivo genotoxicity tests.   

Duloxetine - Administered in the diet to rats and mice for 2 years. In rats, did not cause any increase in incidence of expected or unusual neoplasms or decrease in the latency for any tumor type. In female mice, there was an increased incidence of hepatocellular adenomas and carcinomas at the high dose only (144 mg/kg/day), but these were considered to be secondary to hepatic enzyme induction with associated centrilobular hypertrophy and vacuolation.
