What is the most important information I should know about Allerfin?

Injection: Allerfin is contraindicated in comatose states, in patients who have received large amounts of central-nervous-system depressants (alcohol, sedative hypnotics, including barbiturates, general anesthetics, narcotics, narcotic analgesics, tranquilizers, etc.), and in patients who have demonstrated an idiosyncrasy or hypersensitivity to promethazine.

Under no circumstances should promethazine be given by intra-arterial injection due to the likelihood of severe arteriospasm and the possibility of resultant gangrene

Allerfin HCl injection should not be given by the subcutaneous route; evidence of chemical irritation has been noted, and necrotic lesions have resulted on rare occasions following subcutaneous injection. The preferred parenteral route of administration is by deep intramuscular injection.

Syrup, Tablets and Suppositories: Phenergan Tablets and Suppositories are contraindicated for use in pediatric patients less than two years of age.

Phenergan Tablets and Suppositories are contraindicated in comatose states, and in individuals known to be hypersensitive or to have had an idiosyncratic reaction to promethazine or to other phenothiazines.

Antihistamines are contraindicated for use in the treatment of lower respiratory tract symptoms including asthma.

Use Allerfin as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Allerfin may be taken with or without food.
• If you miss a dose of Allerfin, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Allerfin.

What other drugs will affect Allerfin?

Activity increases when combined with beta-lactam antibiotics, aminoglycosides, vancomycin, clindamycin, metronidazole. Sukralfat, bismuth preparations, antacids containing aluminum ions, magnesium or calcium, cimetidine, ranitidine, vitamin and mineral supplement, iron sulfate, zinc, didanosine (recommended for 2 hours before or 4 hours after these drugs) reduce the suction. Probenecid, azlocillin increase the concentration in the blood. Decreases clearance and increases in plasma caffeine, aminophylline and theophylline (increased likelihood of side effects). Allerfin Citadel Fine Pharmaceuticals enhances the effect of warfarin and other oral anticoagulants (prolongs bleeding time). Increases nephrotoxicity of cyclosporine, increase the risk of CNS excitability and convulsive reactions against the background of NSAIDs. Medicines alkalinizing the urine (citrates, sodium bicarbonate, carbonic anhydrase inhibitors) reduce the solubility (increases the probability of crystalluria). Infusion solutions of ciprofloxacin ready to use can be combined with infusion solutions: 0.9% sodium chloride solution, Ringer's solution, Ringer lactate, 5 and 10% dextrose, 10% solution of fructose, and a solution containing 5% dextrose with 0,225 or 0.45% sodium chloride. Incompatible with solutions having a pH > 7.
