Respiratory Bronchospasm may be a consequence of penicillin allergy. Acute severe dyspnea with cyanosis has also been observed without symptoms of bronchial obstruction or pulmonary edema. Specific mechanisms for such cases have yet to be identified. Allergic pneumonitis and transient eosinophilic pulmonary infiltrate (Loeffler’s syndrome) are rare. These syndromes have also been observed with penicillin hypersensitivity. In one case, an alveolar allergic reaction, probably due to ampicillin, showed features of an adult respiratory distress syndrome. Nervous system High doses of penicillins, …

Type I reactions Anaphylactic shock can occur, even after oral administration of penicillin and skin testing. However, anaphylactic shock is less common after oral than parenteral administration. In one study the incidence of anaphylactic shock was 0.04% of all patients treated with penicillin. It is also low in patients receiving long-term benzathine penicillin (1.2 million units every 4 weeks). Four episodes of anaphylaxis occurred in 0.012% of injections (1.2 reactions to 10 000 injections). Anaphylactic shock resulting in death occurred in 0.002% of all patients treated with penicillin and in 0.003% of those treated with benzathine penicillin. In …

Penicillin-contaminated milk or meat can cause itching or generalized skin reactions or even anaphylaxis. Incidence The overall annual incidence of severe erythema multi-forme (toxic epidermal necrolysis and Stevens-Johnson syndrome) is about one case per million, antibiotics being involved in 30-40%. The clinical differentiation between these syndromes can be difficult. Allergic contact dermatitis is usually caused by topical drugs, but is also seen in connection with ingestion, injection, or inhalation. The increased frequency of contact eczema due to cloxacillin and bacampicillin may be because they are intensely irritant and …

The first was a comparison of the assessment of drug-induced liver injury obtained by two different methods, the Council for International Organizations of Medical Sciences (CIOMS) scale and the Maria & Victorino (M&V) clinical scale. Three independent experts evaluated 215 cases of hepatotoxicity reported using a structured reporting form. There was absolute agreement between the two scales in 18% of cases, but there was no agreement in cases of fulminant hepatitis or death. The authors concluded that the CIOMS instrument is more likely …

Information on this association has come predominantly from case series and hospital surveys (38^. Some evidence can be extracted from population-based studies that have focused on aplastic anemia and agranulocytosis and their association with many drugs, including antimicrobial drugs. The incidence rates of blood dyscrasias in the general population have been estimated in a cohort study with a nested case-control analysis, using data from a General …
