Cromolyn is a medicine that is usually applied to stabilize the mast cells (called mastocystes), responsible for the release of certain mediators. It can be prescribed to treat asthma manifestations and gastrointestinal diseases. In both conditions, the production of this mediator causes a local inflammation, leading to systemic allergic reaction. Cromolyn has no antihistaminic or anti inflammatory activity.
Cromolyn or Cromolyn is prescribed to prevent the symptoms of asthma. When it is prescribed properly, it acts by reducing the number and the severity of asthma attacks by reducing the inflammation located into the patient's lungs. The medicine can also be prescribed to treat certain exposures to diseases or substances such as allergens, pollen, Aspirin, chemicals, or other pollutants, that can lead to wheezing or difficult breathing. Cromolyn is applied to prevent the asthmatic attacks and not to relieve the attacks that have already started. The use of this clinical remedy can also provide a certain individual with other beneficial effects and / or actions. For further information, contact your health care specialist.


It is very important not to take excessive amounts of Cromolyn if the patient is pregnant or plans to become pregnant because its ingredients can affect the unborn baby. There are other warnings that the patient should consider while taking the medicine and can include the dosage (because high doses of Cromolyn can cause life threatening complications). Before you start taking Cromolyn, you should inform your personal physician if you are suffering from any other medical conditions, especially one or more of the following: chronic or active bacterial, viral, or fungal infection. The patient must also be careful if he is currently receiving phototherapy or he/she is suffering from a suppressed immune system. If you present any of the medical conditions that we have listed here, you might not be allowed to start taking Cromolyn.

Intake Guidelines

Cromolyn is generally prescribed to prevent any attacks of asthma, and to treat certain gastrointestinal disorders. It is important to take the medicine at scheduled times, which have been directed by your personal health care provider. Do not take overdoses and do not use it more often than the doctor indicated, because you can increase the risk of developing side effects. Cromolyn usually has strict indications about applying it, and it is better to read them carefully before using the medicine; if you do not fully understand them, or you are not sure how to use the inhaler, you should ask your pharmacist or the health care professional for extra instructions. Do not stop your treatment with Cromolyn without your personal physician's consent, as this could have severe consequences.


The dosage of Cromolyn depends on the patient's disease and the severity of the present manifestations. Usually, for the tablet form of the medicine, the initial dose consists in two capsules which should be taken after main meals, four times a day. To maintain a proper health status, the doses can be increased with other two tablets. The dosage is applied differently in young patients, which are administered only half of the adult prescribed dose. After the patient achieves a favorable improvement, the doses of Cromolyn can be reduced to a minimum, depending on the patient's symptoms. You should not alter the dosage of Cromolyn that your personal physician has given you because this may alter the drug's benefic effects and it also might lead to an accidental and unwanted overdose.


Usually, an overdose of Cromolyn does not cause any severe manifestations but, it depends on the patient's age, sex and immune system resistance, because some persons can develop severe side effects. If you suspect an overdose with Cromolyn it is recommended to contact the health care provider as soon as possible.

Missed Dose

If the patient is using Cromolyn and he/she misses a dose, it is recommended to take it as soon as possible. Do not take double doses, because you can easily develop serious side effects that can worsen your condition. If it is already about time for another scheduled dose, skip the one that you have missed and continue your normal dosing program. But it is recommended to contact the doctor for further instructions.

Side Effects

Cromolyn, like other medicines, in addition to its benefic effects, can cause certain side effects that can appear depending on each person. The most common side effects that the patient can develop during the treatment with this kind of medicine include hives, difficulty in swallowing, increased wheezing, difficulty in breathing, itching of skin, low blood pressure, shortness of breath, swelling of the face, lips, or eyelids, and tightness inside the chest. There are other less common side effects, but they do not usually require any medical attention. These manifestations can go away on their own during the treatment, as the patient's body accommodates with Cromolyn. It is recommended to contact the individual's personal doctor as soon as the patient experiences any abnormal changes. Some side effects can appear as nausea, coughing, throat irritation and dryness. When a patient is using Cromolyn inhalation aerosols, he/she can experience a bad mouth taste that can go away after the end of the individual's therapy with Cromolyn.
