is it a teratogen? | Widely distributed in the body and cross the placenta and enter the breast milk |
Fluoroquinolones: Pharmacokinetics: Caution with patients with? | renal and hepatic impairment, w/c could interfere w/ metabolism and excretion |
Fluoroquinolones: Contraindications and cautions: 1: | Known allergy to any fluoroquinolones, pregnant and lactating women because of unknown effects on fetuses and infants |
Fluoroquinolones: Contraindications and cautions: 2: Decrease the absorption & should not be given 2 hours following administration of the antibiotic | Antacids |
Fluoroquinolones: Contraindications and cautions: Caution with what?
w/c could interfere drug excretion and seizure, w/c could be exacerbated by the drugs effects on cell membrane channels | Renal dysfunction |
Fluoroquinolones: Adverse effects: 1: Generally associated with relatively mild adverse reactions: | Headache, dizziness, insomnia, and depression related to direct drug effects on the GI tract and possible stimulation of the chemoreceptor trigger zone in the CNS. |
