Flecainide causes or worsens heart failure in about 5% of people taking it because it tends to reduce the force and rate of each heartbeat.
Flecainide is extensively broken down in the liver. People with poor liver function should not take flecainide unless the benefits clearly outweigh the risks.
Changes in the pH of urine may affect the effectiveness of flecainide.
Possible Side Effects

Prescribed For
Infections of the lower respiratory system, sinuses, urinary tract, skin, bone and joints, lungs, and prostate; also prescribed for sexually transmitted diseases, prostatitis, infectious diarrhea, bronchitis, pneumonia, typhoid fever, anthrax, and traveler’s diarrhea. The eyedrops are used to treat ocular infections, the eardrops for ear infections.
General Information
Fluoroquinolone anti-infectives work against many organisms that traditional antibiotics have trouble killing. They do not work against the common cold, flu, or other viral infections. The fluoroquinolones were first used as treatment for urinary infections and then other uses developed over the years. The new uses depend on how well the specific drug penetrates different body tissues as well as on how they have been tested in the laboratory. Individual fluoroquinolones are not all equally effective in treating all infections.
Cautions and Warnings
Do not take a fluoroquinolone if you are allergic or sensitive to any of its ingredients, or to any drug in this group, or have had a reaction to related medications such as nalidixic acid. Severe, possibly fatal, allergic reactions can occur even after the very first dose. These reactions include cardiovascular collapse, loss of consciousness, tingling, swelling of the face or throat, breathing difficulties, itching, and rash. Stop taking the drug if you experience allergic symptoms and seek medical help at once.
Fluoroquinolones may cause increased pressure on parts of the brain, leading to convulsions and psychotic reactions. Other possiblp. tIWA include tremors, restlessness, lightheadedness, confusion, and hallucinations. Fluoroquinolones should be used with caution in people with head trauma, seizure disorders, or other nervous system conditions.
Moxifloxacin should not be used by people with liver disease.
Moxifloxacin should be avoided by people with heart rhythm problems or those taking drugs that can affect heart rhythm.
People with kidney disease require reduced dosage of these drugs, except in the case of moxifloxacin.
People taking fluoroquinolones may be unusually sensitive to the sun. Avoid the sun while taking this drug and for several days following therapy, even if you are using sunscreen.
People taking a fluoroquinolone may develop colitis that could range from mild to very serious. Contact your doctor if you develop diarrhea or cramps.
Fluroquinolones can worsen myasthenia gravis. Use with caution.
Prolonged fluoroquinolone use can lead to fungal overgrowth.
Patients taking a fluoroquinolone may experience ruptures of the shoulder, hand, Achilles tendon, or other tendons that may require surgery or lead to extended disability.
Possible Side Effects
Side effects are rarely serious.
♦ Common: nausea (most likely with ciprofloxacin and moxifloxacin), vomiting, and diarrhea (may be most likely with moxifloxacin and ofloxacin).
✓ Less common: dizziness, abdominal pain, headache, and liver inflammation.
✓ Rare: Rare side effects, including some severe drug reactions, can occur in almost any part of the body. In once-daily studies of ciprofloxacin eardrops, there were a few reports of nausea, formation of flaky scales, inflammation of the external ear, temporary hearing loss, ringing or buzzing in the ears, middle-ear inflammation, tremors, high blood pressure, and fungal infection. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Separate your fluoroquinolone dose from that of antacids, didanosine, iron supplements, or zinc by 2-6 hours. These drugs decrease the amount of fluoroquinolone absorbed. Moxifloxacin must be taken 4 hours before or 8 hours after antacids, iron, or zinc.
• Nitrofurantoin may antogonize norfloxacin’s antibacterial effects. Do not take these drugs together.
• Moxifloxacin can increase the risk of abnormal heart rhythms.
Combining this drug with astemizole, erythromycin, tricyclic
antidepressants, and antipsychotics increases the risk of ab-
normal heart rhythms associated with this drug.
• People taking drugs to correct abnormal heart rhythms should avoid Fluoroquinolones.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) and anti-inflammatory drugs should not be combined with fluoroquinolones because of the increased risk of stimulation and seizures.
• Sucralafate reduces the amount of fluoroquinolone absorbed in the blood. Take sucralafate at least 6 hours after taking a fluoroquinolone.
• Probenecid may increase the risk of some fluoroquinolone side effects. Cimetidine may also increase fluoroquinolone blood levels.
• Fluoroquinolones (except moxifloxacin) may increase the effect of oral anticoagulant drugs such as warfarin. Your anticoagulant dosage may have to be reduced.
• Fluoroquinolones may increase the toxic effects of cy-
closporine (used for organ transplants) on your kidneys.
• Fluoroquinolones (except moxifloxacin) may increase theophylline blood levels and the risk of side effects.
• Azlocillin may increase the risk of ciprofloxacin side effects.
• Ciprofloxacin and norfloxacin may increase caffeine’s effects.
Food Interactions
Levofloxacin, lomefloxacin, and moxifloxacin may be taken with or without food. Take ofloxacin and norfloxacin at least 2 hours before or 2 hours after meals or antacids. Ciprofloxacin is best taken 1 hour before or 2 hours after meals, but may be taken with food. Dairy products and calcium-fortified orange juice interfere with the absorption of ciprofloxacin and should be avoided.
Usual Dose

Brand Name
Dalmane
Type of Drug Benzodiazepine sedative.
Prescribed For
Insomnia and sleep disturbances.
General Information
Flurazepam is a member of the group of drugs known as benzodiazepines. Benzodiazepines work by a direct effect on the brain. They make it easier to go to sleep and decrease the number of times you wake up during the night. Flurazepam and quazepam remain in your bloodstream longer than other drugs in this class, thus resulting in the greatest incidence of morning “hangover.”
Cautions and Warnings
Do not use flurazepam if you are allergic or sensitive to any of its ingredients.
People with kidney or liver disease should be carefully monitored while taking flurazepam. Take the lowest possible dose to help you sleep.
People with respiratory disease may experience sleep apnea (intermittent cessation of breathing during sleep) while taking flurazepam.
Clinical depression may be increased by flurazepam, which can depress the nervous system. Intentional overdose is more common among depressed people who take sleeping pills than among those who do not.
Some people have experienced amnesia while taking flurazepam.
All benzodiazepines can be addictive if taken for long periods of time and can cause drug withdrawal symptoms if discontinued suddenly. It should be used with caution in people with a history of drug dependence. Withdrawal symptoms include tremors, muscle cramps, insomnia, agitation, diarrhea, vomiting, sweating, and convulsions.
Tapering the drug when stopping may help prevent withdrawal symptoms. People with a history of seizures should be particuarly cautious when stopping use of this drug.
Possible Side Effects

Drug Interactions
• As with all benzodiazepines, the effects of flurazepam are enhanced if it is taken with an alcoholic beverage, antihistamine, sedative, barbiturate, anticonvulsant medication, antidepressant, or monoamine oxidase inhibitor antidepressant.
• Contraceptive drugs, cimetidine, disulfiram, and isoniazid may increase the effect of flurazepam by reducing the drug’s breakdown in the liver. Probenecid also increases flurazepam’s effects.
• Cigarette smoking, rifampin, and theophylline may reduce the effect of flurazepam on your body by increasing the rate at which it is broken down by the liver.
• Levodopa + carbidopa’s effectiveness may be decreased by flurazepam.
• Flurazepam may increase the amount of zidaw-adwie tan HIV drug—also known as pnenytoin, or digoxin in your WZWMTeam, increasing the chances of side effects.
