The following adverse reactions have been identified during post-approval use of BOTOX. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These reactions include: abdominal pain; alopecia , including madarosis; anorexia ; brachial plexopathy; denervation /muscle atrophy ; diarrhea; hyperhidrosis; hypoacusis; hypoaesthesia; malaise ; paresthesia ; peripheral neuropathy ; radiculopathy ; erythema multiforme , dermatitis psoriasiform, and psoriasiform eruption; strabismus; tinnitus ; and visual disturbances.
A variety of infectious agents may be transmitted by transfusion. Definitive evidence of transmission by transfusion requires demonstration of seroconversion or new infection in the recipient and isolation of an agent with genomic identity from both the recipient and the implicated donor. Strong presumptive evidence of transfusion transmission includes recipient seroconversion within an appropriate interval after transfusion, the recognition of appropriate infectious markers in an implicated donor on follow-up investigation, or both. Transfusion transmitted disease should be reported to the Australian Red Cross Blood Service.
