Alerion review

Alerion 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 conjunctivitis.


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

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


Dosages of Alerion vary and are prescribed based on the condition being treated. For food allergies, Alerion is usually prescribed to adults as 200 mg tablets 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 patients with mastocytis, a 20 milligram dosage is taken 4 times a day. For patients with allergic conjunctivitis, Alerion is usually administered by instilling 2 drops of a 4% solution spray, taken four times a day.

Asthmatics may use Alerion 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. If 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 after the condition has improved.


Patients taking Alerion may experience side effects ranging from skin rashes, nausea, dizziness, headache, pain and swelling in the joints, and unpleasant taste in the mouth. Patients may also aggravate their asthma attacks, or suffer from pulmonary infiltrates. Other patients may also experience wheezing, nasal congestion, cough, and throat irritation especially after inhaling the dry powder. For patients who use eye drops, there is a risk of stinging and burning in the eyes.

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


Alerion 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 Alerion without the approval of their doctor or pharmacist.

Those who are using Alerion 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.


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