Overdose of Proflaxin in details
In the event of acute overdosage, reversible renal toxicity has been reported in some cases. The stomach should be emptied by inducing vomiting or by gastric lavage. The patient should be carefully observed and given supportive treatment, including monitoring of renal function, urinary pH and acidify, if required, to prevent crystalluria and administration of magnesium, aluminum, or calcium containing antacids, which can reduce the absorption of Proflaxin. Adequate hydration must be maintained. Only a small amount of Proflaxin (< 10%) is removed from the body after hemodialysis or peritoneal dialysis.
Single doses of Proflaxin were relatively non-toxic via the oral route of administration in mice, rats, and dogs. No deaths occurred within a 14-day post treatment observation period at the highest oral doses tested; up to 5000 mg/kg in either rodent species, or up to 2500 mg/kg in the dog. Clinical signs observed included hypoactivity and cyanosis in both rodent species and severe vomiting in dogs. In rabbits, significant mortality was seen at doses of Proflaxin > 2500 mg/kg. Mortality was delayed in these animals, occurring 10 to 14 days after dosing.
In mice, rats, rabbits and dogs, significant toxicity including tonic/clonic convulsions was observed at intravenous doses of Proflaxin between 125 and 300 mg/kg.
What should I avoid while taking Proflaxin?
You may be taking certain other medicines that should not be taken at the same time as Proflaxin. Avoid taking the following medicines within 6 hours before or 2 hours after you take Proflaxin. These other medicines can make Proflaxin much less effective when taken at the same time:
-
antacids that contain magnesium or aluminum (such as Maalox, Mylanta, or Rolaids), or the ulcer medicine sucralfate (Carafate);
-
didanosine (Videx) powder or chewable tablets;
-
vitamin or mineral supplements that contain calcium, iron, or zinc.
Avoid caffeine while you are taking Proflaxin, because the medication can make the effects of caffeine stronger.
Avoid exposure to sunlight or tanning beds. Proflaxin can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors. Call your doctor if you have severe burning, redness, itching, rash, or swelling after being in the sun.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop taking Proflaxin and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Proflaxin may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Proflaxin warnings
Patients should be advised:
· that antibacterial drugs, including Proflaxin, should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Proflaxin is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Proflaxin or other antibacterial drugs in the future.
· that Proflaxin should only be used to treat uncomplicated urinary tract infections (also known as bladder infections). The safety and efficacy of Proflaxin to treat other urinary tract or non-urinary tract infections have not been studied.
· that Proflaxin should be taken with a main meal of the day, preferably the evening meal. The patient should not take more than one Proflaxin tablet per day, even if the patient misses a dose.
· that Proflaxin tablets should be taken whole and never split, crushed, or chewed.
· that concomitant administration of Proflaxin with aluminum or magnesium-containing antacids, sucralfate, VIDEX (didanosine) chewable buffered tablets or pediatric powder, metal cations such as iron and calcium, and multivitamin preparations containing zinc should be avoided. Proflaxin should be administered at least 4 hours before or 2 hours after these products.
· that Proflaxin should not be taken with dairy products (like milk or yogurt) or calcium-fortified juices alone, since the absorption of Proflaxin may be significantly reduced. However, Proflaxin may be taken with a meal that contains these products.
· that Proflaxin may be associated with hypersensitivity reactions, even following a single dose, and to discontinue Proflaxin at the first sign of a skin rash or other allergic reaction and contact their physician.
· to avoid excessive sunlight or artificial ultraviolet (UV) light while receiving Proflaxin and to discontinue therapy if phototoxicity occurs.
· that peripheral neuropathies have been associated with Proflaxin use. If symptoms of peripheral neuropathy including pain, burning, tingling, numbness and/or weakness develop, patients should discontinue treatment and contact their physician.
· that if they experience pain, inflammation, or rupture of a tendon to discontinue treatment, to inform their physician, and to rest and refrain from exercise.
· to contact their doctor if they do not feel better of if they develop fever and back pain while or after taking Proflaxin.
· that Proflaxin may cause dizziness and lightheadedness; therefore, patients should know how they react to this drug before they operate an automobile or machinery or engage in activities requiring mental alertness or coordination.
· that Proflaxin may increase the effects of theophylline and caffeine. There is a possibility of caffeine accumulation when products containing caffeine are consumed while taking quinolones.
· that convulsions have been reported in patients receiving quinolones, including Proflaxin, and to notify their physician before taking this drug if there is a history of this condition.

Proflaxin precautions
Tablet: Proflaxin should be used with caution in patients with epilepsy or a history of CNS disorders. Care is necessary in patients with impaired hepatic or renal function, glucose-6-phosphate dehydrogenase deficiency or myasthenia gravis. An adequate fluid intake should be maintained during treatment with Proflaxin and excessive alkalinity of the urine avoided because of the risk of crystalluria. Exposure to strong sunlight or sun lamps should also be avoided.
Effects on the Ability to Drive or Operate Machinery: The ability to drive or operate machinery may be impaired by Proflaxin, especially when alcohol is also taken.
Eye Drops: Proflaxin eye drops is not for injection into the eye.
In patients receiving systemic quinolone therapy, serious and occasionally fatal hypersensitivity reactions have been observed following the 1st dose. Some reactions were accompanied by cardiovascular collapse, loss of consciousness, tingling, pharyngeal or facial edema, dyspnea, urticaria and itching.
Prolonged use of any antibacterial preparation may result in overgrowth of nonsusceptible organisms including fungi; it also holds true with Proflaxin. In case of superinfection, appropriate therapy must be initiated. Proflaxin should be discontinued at the first appearance of a skin rash or any other sign of hypersensitivity reaction. Remove contact lenses before use.
Use in pregnancy & lactation: There are no adequate and well-controlled studies in pregnant women. Reproduction studies in rats and mice at doses up to 6 times the usual daily human oral dose have revealed no evidence of impaired fertility or harm to the fetus due to Proflaxin. In rabbits, as with most antimicrobial agents, Proflaxin (30 and 100 mg/kg orally) produced gastrointestinal disturbances resulting in maternal weight loss and an increased incidence of abortion. No teratogenicity was observed at either dose. Proflaxin ophthalmic solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Caution should be exercised when Proflaxin eye drops is administered to a nursing mother. It is, however, not known whether topically applied Proflaxin is excreted in human milk.
Use in children: Safety and efficacy of Proflaxin eye drops have not been established in pediatric patients <1 year.
What happens if I miss a dose of Proflaxin?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
