Nalcrom (sodium cromoglycate) is a mast cell stabilizer used to treat or prevent a range of allergic reactions, most notably food allergies, but it can be used in a range of other allergies as well. The medication should not be relied on to prevent a life-threatening reaction to food or any other substance.

Nalcrom will have no influence on food intolerances, such as lactose intolerance, which are their own category. There is a lot of uncertainty and crossover, however; it may be unclear if a certain food triggers an intolerant or allergic reaction, while others may do both.

The medication can be used in patients aged 2 and up, though younger patients require modified doses.

How to Take Nalcrom

Nalcrom comes in 100 mg tablets; it is not available in other strengths. It is typically prescribed to prevent allergic reactions in patients who suffer from disruptive, but not life-threatening, reactions to food or other items. For example, the medication may be used to treat:

  • Allergic eczema
  • Tiredness
  • Vomiting
  • Loose and/or frequent stools
  • Pallor
  • Mucous in stools
  • Nausea

Symptoms that generally aren't treated with Nalcrom include:

  • Weak, rapid pulse
  • Severe dizziness
  • Fainting
  • Difficulty breathing
  • Hives, severe itching
  • Swelling of tongue, face, or throat

The above symptoms, also known collectively as anaphylaxis, present a serious and life-threatening situation. They typically occur within moments of encountering the allergen, and warrant immediate, emergency medical attention. Patients who are at risk of anaphylaxis are typically prescribed an EpiPen for use in such scenarios; even if an EpiPen is used and the patient seems better, still seek medical attention---the EpiPen will wear off eventually and problems may resume.

Treatment with Nalcrom occurs when the allergen is unavoidable, either because the patient can't avoid it or because the patient doesn't want to avoid it. In the latter case the allergic reactions is typically mild.

Treatment is roughly similar in all uses, but some variance is not unusual:

  • Take 200 mg 4 times per day, ideally spaced evenly apart.
  • If taking for food allergies, administration should occur 30 to 60 minutes prior to a meal if possible; all 4 daily doses should still be taken, however, even without food.
  • If, after 2 weeks of treatment, there is no improvement, dosage may be doubled.
  • Continue treatment for as long as it provides benefit.

Discuss dosage amounts for children with a doctor.

Potential Side Effects

The most common side effects with Nalcrom are typically mild and not cause for concern. These effects are often transient; speak with a doctor if they become severe enough to be disruptive:

  • Cough
  • Nausea
  • Vomiting
  • Headache
  • Diarrhea
  • Sneezing
  • Unpleasant taste
  • Difficulty sleeping

The medication is very unlikely to produce more serious side effects, although, ironically, some individuals will experience an allergic reaction to it. Warning signs include swelling of the face or throat, hives, low blood pressure, weak and/or rapid heartbeat, and hives. An allergic reaction warrants emergency medical attention.

Nalcrom can interact with a range of other medications. Always check with a doctor or pharmacist before mixing treatments while taking Nalcrom.

    For a long time I thought I had irritable bowel syndrome. Finally had skin prick testing done to find out I'm allergic to eggs, fish and shellfish.... easy to avoid these things themselves but wow, eggs especially are in so much prepared food, and eating out food is often contaminated with traces of it. Started on Nalcrom a couple months ago and my stomach has settled down a lot. Hopefully it will continue to do so. I'm happy with it so far.
