The status of the patients renal function and hepatic function must also be taken into consideration to avoid an accumulation that may lead to a fatal drug overdose. Ofloxacin is eliminated primarily by renal excretion. However, the drug is also metabolized and partially cleared through the liver. Modification of the dosage is required using the table found within the package insert for those with impaired liver or kidney function (particularly for patients with severe renal dysfunction). However, since the drug is known to be substantially excreted by the kidneys, the risk of toxic reactions to this drug may be greater in patients with impaired renal function. The duration of treatment depends upon the severity of infection and the usual duration is 7 to 14 days. Antibiotic use and bacterial resistance
Resistance to ofloxacin and other fluoroquinolones may evolve rapidly, even during a course of treatment. Numerous pathogens, including Staphylococcus aureus, enterococci, and Streptococcus pyogenes now exhibit resistance worldwide.Floxacin and other fluoroquinolones had become the most commonly prescribed class of antibiotics to adults in 2002. Nearly half (42%) of these prescriptions were for conditions not approved by the U.S. Food and Drug Administration (FDA), such as acute bronchitis, otitis media, and acute upper respiratory tract infection, according to a study that was supported in part by the Agency for Healthcare Research and Quality. Additionally they are commonly prescribed for medical conditions that are not even bacterial to begin with, such as viral infections, or those to which no proven benefit exists. References

Articular branches - There are three articular branches arises from the upper part of the fossa: superior medial genicular nerve (located on the surface of medial condyle of femur, middle genicular nerve (pierces the posterior capsule of the knee joint to supply the structures located in the intercondylar notch of the femur, and inferior genicular nerve (runs along the upper border of the popliteus to reach the medial condyle of tibia). Back of the leg
At the inferior angle of the popliteal fossa, tibial nerve passes deep to the tendinous arch of soleus to enter the back of the leg. In the leg, it runs downwards and medially to reach the posteromedial side of the ankle, midway between the medial malleolus and medial tubercle of the calcaneum. It terminates deep to the flexor retinaculum at the origin of the abductor hallucis by dividing into medial and lateral plantar nerves to supply the foot. The tibial nerve gives off several branches to supply the back of the leg:
Muscular branches - Supplies tibialis posterior, flexor digitorum longus, flexor hallucis longus, and deep part of soleus. Cutaneus branches - The medial calcaneal nerve pierces the flexor retinaculum to supply the skin of the back and lower surface of the heel. Articular branches - Supplies the ankle joint

Foot
In the foot, the nerve terminates by dividing into medial and lateral plantar branches. Medial plantar nerve - It is the larger terminal branch of the tibial nerve. It passes between the abductor hallucis and flexor digitorum brevis to divide further into branches.
