What Is Intal?

Intal (cromolyn) is a prescription medication used to manage asthma by preventing bronchospasm and allergic airway reactions. It works by stabilizing mast cells in the airways, blocking the release of histamine and other inflammatory mediators that trigger asthma symptoms. With the right dose and ongoing monitoring, many patients experience fewer asthma attacks and reduced reliance on rescue inhalers.

Is Online Intal Treatment Right for You?

Intal may be appropriate for adults with persistent asthma, particularly those whose symptoms are triggered by allergens, exercise, or environmental irritants. It is used as a preventive (controller) medication and is not intended to relieve an acute asthma attack already in progress.

Because cromolyn acts directly on the respiratory system, candidates should have a confirmed asthma diagnosis and no history of hypersensitivity to cromolyn sodium. Your physician will review your breathing history and current asthma control to determine whether Intal is the right controller therapy for you.

Frequently asked questions

Intal contains cromolyn sodium, a mast cell stabilizer. When inhaled before exposure to a known trigger such as an allergen or exercise, it prevents mast cells in the airways from releasing histamine and other inflammatory chemicals. This blocks the chain of events that would otherwise cause bronchospasm and asthma symptoms.

No. Intal is a preventive medication and does not relax airway smooth muscle. It will not relieve an acute bronchospasm. You should continue to keep a short-acting rescue inhaler such as albuterol available for sudden symptoms.

Intal generally requires several weeks of regular use before its full preventive benefit is seen. Some patients notice gradual improvement in symptom frequency and severity over two to four weeks of consistent daily therapy.

For ongoing asthma control, cromolyn is typically inhaled three to four times daily at regular intervals. For exercise-induced bronchospasm, it can be inhaled 10 to 15 minutes before physical activity. Your prescribing physician will tailor the dosing schedule to your specific situation.

Cromolyn is generally well tolerated. The most commonly reported side effects include throat irritation, cough, and an unpleasant taste after inhalation. Serious allergic reactions are rare. Contact your doctor if you notice wheezing, rash, or swelling after use.

Intal is contraindicated in people with a known hypersensitivity to cromolyn sodium. It is not appropriate as monotherapy for patients who need immediate bronchodilation. People with severely compromised lung function should discuss all controller options with their physician before starting cromolyn.
