Preface
The purpose of this book is to clarify the use of antibiotics in the
management of the eommon respiratory illnesses seen in general
practiee. The underlying philosophy, whieh embraees the avoidanee of
unneeessary use, is that proper use entails a full understanding of the
nature of the illness.
The eoneept of seleetive antibiotie use reeognizes that respiratory
illnesses eommonly eomprise multiple illness features, and that some of
these features have a viral cause and some a bacterial one. In assessing
antibiotic need, eaeh feature or eomponent part of an illness may be
evaluated individually, so enabling adecision for antibiotie use in the
illness as a whole.
The nature of eaeh individual illness feature with its antibiotic
indication is diseussed in sueeessive ehapters, and this aecumulated
knowledge is of value in managing the more eomplex PUO and flu-like
illnesses whieh are diseussed at the end of the book.
The first two ehapters eneompass the principles of antibiotic use and
the relationship between antibiotie preseribing and various states of the
patient, e.g. allergy, pregnaney ete.
An attempt has been made to justify every reeommendation or
decision, and non-antibiotic management is diseussed where relevant.

pregnancy long before its publication, and Professor D. Vere of the
Department of Pharmacology and Therapeutics, The London Hospital
Medical College, for correspondence relating to the absorption of anti
convulsant drugs. I acknowledge the contribution made by two past
Editors of the Journal 0/ the Royal College 0/ General Practitioners,
Dr D. J. Pereira Gray and Dr S. L. Barley, in stimulating thought.
I am grateful to Searle & Co. Ltd. for information relating to inter
action between antibiotics and progesterone-only pills. A colleague and
her son very kindly sat for the photographs in Chapter 5. Miss Sue

Antibiotics and the Patient
Allergy - Antibiotic Diarrhoea - The Contraceptive Pill-Pregnancy -
Lactation - Neonates - Children - The Elderly - Hepatic and Renal
Impairment - Drug Interactions - Absorption
The use of any drug entails more than a consideration of the disease
itself. When prescribing an antibiotic, the possibility of inducing an
allergic reaction and of inducing antibiotic diarrhoea is borne in mind,
and of the many states of the patient, the possibility of pregnancy is
never far from the general praetitioner's thoughts.
ALLERGY
Allergy to Penicillin
Allergie reactions are caused more commonly by penicillin than by
other antibiotics, and a story of allergy to one type of penicillin must be
assumed to refleet allergy to all types. This is because all penicillins
contain the 6-aminopenicillanic acid nucleus from which the res
ponsible major and minor determinants are derived. Enquiry of known
allergy should be made when the use of penicillin is proposed, and this
serves to prevent some reactions, but many instances of allergy occur
despite previous safe use.
Anaphylactic Shock
This, the most severe reaction, develops between three and 30 minutes
after dosage and may be fatal. This type of reaction is rare and has
1

occurred usually after parenteral dosage, but instances following the
use of oral penieillin are described (Simmonds et al. 1978, Schwartz and
Sher 1984). If a general practitioner has had the experience of a patient
'collapsing on the end of the needle', he will probably never give intra
muscular penieillin again; fortunately patients needing antibioties in
general practiee can invariably be managed using the oral route.
The clinieal features of anaphylactic shock comprise hypotension,
tachycardia, loss of consciousness, and in addition, there may be other
allergie features, e.g. laryngeal oedema or asthma, and the patient may
become severely cyanosed.
Emergency treatment comprises intra-muscular adrenaline (0.5 ml of
1 in 1(00) whieh may need to be repeated at quarter-hourly intervals,
and intravenous hydrocortisone in a dose of 100 or 200mg, and
intravenous chlorpheniramine in a dose of 10 or 20mg. The establish
ment of an artificial airway may be necessary, e.g. a large-bore needle
through the cricothyroid membrane or a laryngotomy, again through
the cricothyroid membrane (Chapter 7).
Other Allergie Reaetions
Cutaneous urtiearia is unquestionably an allergie reaction and can be
managed by oral antihistamines, but the urticaria may involve the
mouth and pharynx, and sometimes the larynx, when a life-threatening
situation develops. Management then follows the same lines as for
anaphylactie shock. Severe asthma will also be helped by intravenous
hydrocortisone, but now, nebulized salbutamol would be used as well.
The most common allergie reaction is the maculo-papular rash which
can develop up to several days after antibiotic use. There is no life
threatening situation, and the use of oral antihistamines plus stopping
the penicillin is adequate management. The problem is that many such
instances may not represent allergy but reflect the illness itself. This
dilemma invariably occurs in children, and the diagnostie difficulties
can be caused by rubella, modified measles (Le. modified by
immunization) and the less well-known enterovirus rashes. Although a
typieal exanthem progresses from the neck downwards while an allergie
rash appears everywhere at once, the distinction in clinieal practice is
often difficult.
Arnpicillin Allergy in Glandular Fever
It is now well-known that the common maculo-papular rash following
