Raxar FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

Adverse reactions were assessed in clinical trials involving approximately 2500 patients receiving single-dose or multiple-dose regimens of grepafloxacin.

Multiple dose Regimens

Most of the adverse reactions reported in clinical trials were transient in nature, mild to moderate in severity, and required no treatment. Twenty of 1069 patients (1.9%) receiving grepafloxacin 400 mg daily and 50 of 925 patients (5.4%) receiving grepafloxacin 600 mg daily discontinued RAXAR (grepafloxacin) Tablets due to an adverse reaction thought by the investigator to be drug-related.

Table 3 lists adverse events that occurred with frequencies of 1% or greater. These events were thought by the investigators to be drug-related in patients treated with grepafloxacin in multiple dose clinical trials.

Table 4 lists the adverse events which occurred with frequencies of 1% or greater. These events were thought by the investigators to be drug related in patients treated with RAXAR (grepafloxacin) Tablets in single-dose clinical trials.

Observed During Clinical Practice

In addition to adverse reactions reported from clinical trials the following events have been identified during post-approval use of grepafloxacin formulations. Because they are reported voluntarily from a population of unknown size estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal connection to grepafloxacin.

    Eye: Disturbances in vision.
    Non Site specific: Allergic reactions, including anaphylactoid reaction/anaphylactic shock, angioedema, laryngeal edema.
