Contraindications
Hypersensitivity
Cautions
Not for status asthmaticus
Use caution in patients with a history of cardiac arrhythmias
Use caution in renal or hepatic impairment; may require dose adjustment
Some reports of bronchospasm or cough after administration
Patients who develop bronchospasm may not be able to continue therapy despite prior bronchodilator administration; rarely, very severe bronchospasm has been encountered
Not useful in acute situations
Symptoms of asthma may recur if cromolyn sodium reduced below recommended dosage or discontinued
Because it is preventive medication, may take up to four weeks before patient experiences maximum benefit
Stability and safety when mixed with other drugs in a nebulizer not established
Should be administered in a power-driven nebulizer with an adequate airflow rate equipped with a suitable face mask or mouthpiece
Pregnancy & Lactation
Pregnancy
No adequate and well-controlled studies in pregnant women
Animal data
- Reproduction studies with drug administered subcutaneously to pregnant mice and rats at maximum daily doses of 540 mg/kg and 164 mg/kg, respectively, and intravenously to rabbits at a maximum daily dose of 485 mg/kg produced no evidence of fetal malformations; the doses represent approximately 27, 17, and 98 times, respectively, the maximum recommended adult human daily inhalation dose on a mg/m2 basis; adverse fetal effects (increased resorption and decreased fetal weight) were noted only at very high parenteral doses that produced maternal toxicity
Lactation
Not known whether this drug is excreted in human milk; because many drugs are excreted in human milk, exercise caution when cromolyn sodium administered to a nursing woman
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

Patient Handout
cromolyn ophthalmic (eye)
CROMOLYN - OPHTHALMIC
(CROW-mow-lin)
COMMON BRAND NAME(S): Opticrom
USES: This medication is used to treat certain allergic eye conditions (vernal keratoconjunctivitis, vernal conjunctivitis, vernal keratitis). It prevents itching of the eyes that can occur with these conditions. Cromolyn is known as a mast cell stabilizer. It works by blocking certain natural substances (histamine, SRS-A) that cause allergic symptoms.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start using cromolyn and each time you get a refill. If you have any questions, ask your doctor or pharmacist.To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.It is best to avoid wearing contact lenses while using this medication.Use this medication in the affected eye(s) as directed by your doctor, usually 4 times daily. Treatment may be continued for as long as 3 months.Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over the eye and place 1 drop into the pouch. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure. This will prevent the medication from draining away from the eye. Try not to blink and do not rub the eye. Repeat these steps if your dose is for more than 1 drop and for the other eye if so directed.Do not rinse the dropper. Replace the dropper cap tightly after each use.If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Continue using it for the full time prescribed.It may take up to several days of continued use to see a relief in symptoms and up to 6 weeks for full benefit. If immediate relief of symptoms (itching) is needed, use other quick-relief medication (such as eye drops containing antihistamines, decongestants, or nonsteroidal anti-inflammatory drugs-NSAIDs) along with cromolyn as directed by your doctor. Tell your doctor if your condition lasts or gets worse.

If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects.
