"July 13, 2015 -- Pyrethroids are chemicals commonly used in products aimed at killing insects, head lice, and fleas on pets. They were created to replace now-banned chemicals in insecticides and other products.
But new research is raising "...
Severe/Fatal: Anaphylactic reactions have been reported with the use of iron dextran injection; on occasions these reactions have been fatal. Such reactions, which occur most often within the first several minutes of administration, have been generally characterized by sudden onset of respiratory difficulty and/or cardiovascular collapse. Because fatal anaphylactic reactions have been reported after administration of iron dextran injection, the drug should be given only when resuscitation techniques and treatment of anaphylactic and anaphylactoid shock are readily available. (See BOXED WARNING and PRECAUTIONS: General, pertaining to immediate availability of epinephrine.)
Cardiovascular:Chest pain, chest tightness, shock, cardiac arrest, hypotension, hypertension, tachycardia, bradycardia, flushing, arrhythmias. (Flushing and hypotension may occur from too rapid injections by the intravenous route.)
Hematologic/lymphatic: Leucocytosis, lymphadenopathy.
Musculoskeletal/soft tissue: Arthralgia, arthritis (may represent reactivation in patients with quiescent rheumatoid arthritis - See PRECAUTIONS: General), myalgia; backache; sterile abscess, atrophy/ fibrosis (intramuscular injection site); brown skin and/or underlying tissue discoloration (staining), soreness or pain at or near intramuscular injection sites; cellulitis; swelling; inflammation; local phlebitis at or near intravenous injection site.
Miscellaneous: Febrile episodes, sweating, shivering, chills, malaise, altered taste.

Drug/Laboratory Test Interactions: Large doses of iron dextran (5 mL or more) have been reported to give a brown color to serum from a blood sample drawn 4 hours after administration.
The drug may cause falsely elevated values of serum bilirubin and falsely decreased values of serum calcium.
Serum iron determinations (especially by colorimetric assays) may not be meaningful for 3 weeks following the administration of iron dextran.
Serum ferritin peaks approximately 7 to 9 days after an intravenous dose of INFeD (iron dextran) and slowly returns to baseline after about 3 weeks.
Examination of the bone marrow for iron stores may not be meaningful for prolonged periods following iron dextran therapy because residual iron dextran may remain in the reticuloendothelial cells.
Bone scans involving 99m Tc-diphosphonate have been reported to show a dense, crescentic area of activity in the buttocks, following the contour of the iliac crest, 1 to 6 days after intramuscular injections of iron dextran.
Bone scans with 99m Tc-labeled bone seeking agents, in the presence of high serum ferritin levels or following iron dextran infusions, have been reported to show reduction of bony uptake, marked renal activity, and excessive blood pool and soft tissue accumulation.
