Brethine

 
What is Brethine and why is it prescribed?
Brethine is a bronchodilator (a medication that opens the bronchial tubes), prescribed for the prevention and relief of bronchial spasms in asthma. Brethine is also used for the relief of bronchial spasm associated with bronchitis and emphysema. If you experience an immediate allergic reaction or a worsening of a bronchial spasm, notify your doctor immediately.

How should you take Brethine?
Follow your doctors directions for taking Brethine. The action of Brethine may last up to 8 hours. Do not use Brethine more frequently than recommended. If you miss a dose take it as soon as you remember. Then take the rest of your medication for that day in evenly spaced doses. Do not take two doses at once. Store Brethine at room temperature in a tightly closed container, away from light.

Are there any Brethine side effects?
Brethine side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. More common Brethine side effects may include chest discomfort, difficulty in breathing, dizziness, drowsiness, fast, fluttery heartbeat, flushed feeling, headache, increased heart rate, nausea, nervousness, pain at injection site, rapid heartbeat, sweating, tremors, vomiting, and weakness. Less common Brethine side effects may include anxiety, dry mouth, and muscle cramps. Rare Brethine side effects may include inflamed blood vessels.

What are the possible food and drug interactions when taking Brethine?
If Brethine is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. It is especially important to check with your doctor before combining Brethine with Antidepressant drugs known as MAO inhibitors (Nardil, Parnate, others), Beta blockers (blood pressure medications such as Inderal and Tenormin), Diuretics (such as Lasix or HydroDIURIL), Other bronchodilators (such as Proventil and Ventolin), or Tricyclic antidepressant drugs (such as Elavil and Tofranil).

Are there any special warnings about Brethine?
When taking Brethine, you should not use other asthma medications before checking with your doctor. Only your doctor can determine what is a sufficient amount of time between doses. If you find that Brethine is not working, tell your doctor immediately. Consult with your doctor before using Brethine if you have diabetes, high blood pressure, or an overactive thyroid gland, or if you have had seizures at any time. Unless you are directed to do so by your doctor, do not take Brethine if you have heart disease, especially if you also have an irregular heart rate.
