Side-effects

Derek Thaczuk

Side-effects can be divided into two main types. Toxic side-effects are a direct result of the drug itself. For instance, some antibiotics are known to cause gastrointestinal problems in many individuals. Allergic side-effects are those brought on by the individual's reaction (sometimes called hypersensitivity) to a drug. These side-effects are sometimes referred to by doctors as type A and type B reactions.
