Alercom review

Alercom is a mast cell stabilizer that prevents the release of inflammation-inducing chemicals including histamine. It is used to control various conditions including asthma and allergic madras eye.


Alercom is marketed as sodium cromoglicate and cromolyn sodium. It is available as a nasal spray under the brand names Nasalcrom and Rynacrom, which people suffering from allergic rhinitis can use. Patients who have asthma can also buy it under the brand name Intal, while those who have allergic madras eye can purchase it under the brand name Crolom, Opticrom, or Optrex. Patients who have ulcerative colitis and mastocytosis can purchase it under the brand name Gastrocrom.

Alercom has been proven effective in reducing symptoms of various food allergies, and in some cases, chronic migraines.


Dosages of Alercom vary and are prescribed according to the condition being treated. For food allergies, Alercom is usually prescribed to adults as 200 mg pills taken four times a day. The dosage is typically 100 mg for children. Dosage may be increased if the medication is not effective after 2 weeks.

For those with mastocytis, a 20 milligram dosage is taken 4 times a day. For those with allergic madras eye, Alercom is usually administered by instilling 2 drops of a 4% solution spray, taken four times a day.

Asthmatics may use Alercom as a dry powder taking a 20 milligram dosage four times a day. For the aerosol form, the dosage is 10 milligrams taken four times a day. In case the condition does not improve, the intake can be increased up to 8 times a day. This can be lowered to 5 milligrams taken 4 times a day once the condition has improved.


Users of Alercom may experience side effect ranging from rashes, nausea, dizziness, cephalalgia, pain and swelling in the joints, and unpleasant taste in the mouth. Users may also aggravate their asthma attacks, or suffer from pulmonary infiltrates. Others may also experience wheezing, nasal congestion, cough, and throat irritation especially after inhaling the dry powder. For those who use eye drops, there is a risk of stinging and burning in the eyes.

Users may also develop allergic reaction to Alercom. They are advised to immediately inform a physician in case they experience symptoms of allergic reaction such as pruritus, rashes, swelling, difficulty breathing and severe dizziness.


Alercom may interfere when taken with other medications. Users should tell their doctors or physicians if they are taking any medications, whether prescription or non-prescription. They are also advised not to change the dosage of Alercom without the approval of their doctor or pharmacist.

Those who are using Alercom for self-treatment should first clear with their physicians if they are experiencing any of these symptoms: fever, sinus pain, discolored fluid discharged from the nose, and wheezing.


Alercom can also affect pregnant women, although the chances are low. Users should discuss the risks and the benefits of Alercom before taking the medication.
