Why is this medication prescribed?

Brompheniramine is an antihistamine medication commonly prescribed to relieve symptoms associated with allergies, hay fever, and the common cold. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms like sneezing, itching, watery eyes, and runny nose.

Brompheniramine is typically used to alleviate symptoms such as:

  • Sneezing
  • Runny nose
  • Itchy or watery eyes
  • Itching of the nose or throat
  • Nasal congestion

It may also be used to alleviate symptoms of other conditions, such as allergic reactions to insect bites and stings, as well as allergic skin reactions.

How should this medicine be used?

Brompheniramine is typically taken orally as directed by your healthcare provider or as indicated on the medication label. Here are some general guidelines for using brompheniramine:

  • Follow Dosage Instructions: Take brompheniramine exactly as prescribed by your healthcare provider or as directed on the medication label. Do not take more or less of it or take it more frequently than recommended.
  • Take with or without Food: Brompheniramine can usually be taken with or without food. Follow the instructions provided by your healthcare provider or on the medication label.
  • Do Not Crush or Chew Sustained-Release Tablets: If you’re prescribed sustained-release tablets, swallow them whole without crushing or chewing. Doing so ensures that the medication is released into your system gradually over time.
  • Use a Measuring Device: When taking liquid forms of brompheniramine, use a proper measuring device to ensure you’re getting the correct dose. Household teaspoons are not accurate for measuring medications and may lead to dosing errors.
  • Avoid Alcohol: Limit or avoid alcohol consumption while taking brompheniramine, as it can enhance drowsiness and other side effects.
  • Store Properly: Store brompheniramine at room temperature away from moisture, heat, and light. Follow any specific storage instructions provided by your pharmacist.
  • Stay Hydrated: Drink plenty of fluids while taking brompheniramine to help alleviate symptoms and prevent dehydration, especially if you have a cold or allergies.
  • Consult Your Healthcare Provider: If you have any questions or concerns about how to use brompheniramine or if you’re unsure about its proper administration, consult your healthcare provider or pharmacist for personalized guidance.

Always remember to inform your healthcare provider about any other medications, supplements, or medical conditions you have before starting brompheniramine to avoid potential interactions or complications.

Other uses for this medicine

Some off-label uses of brompheniramine may include:

  • Relief of symptoms related to allergic reactions to insect bites and stings.

What special precautions should I follow?

As for special precautions to consider when using brompheniramine:

  • Medical History: Inform your healthcare provider about your complete medical history, including any allergies, existing medical conditions, and medications (prescription, non-prescription, herbal, or dietary supplements) you’re currently taking.
  • Pregnancy and Breastfeeding: If you are pregnant, planning to become pregnant, or breastfeeding, discuss the risks and benefits of using brompheniramine with your healthcare provider. It’s important to weigh the potential risks to the fetus or infant against the benefits of treatment.
  • Children and Elderly: Use caution when giving brompheniramine to children and older adults, as they may be more sensitive to its effects. Dosage adjustments may be necessary based on age and weight.
  • Driving and Operating Machinery: Brompheniramine may cause drowsiness, dizziness, or blurred vision, which can impair your ability to drive or operate machinery safely. Avoid these activities until you know how brompheniramine affects you.
  • Alcohol and Other CNS Depressants: Avoid consuming alcohol or taking other central nervous system (CNS) depressants (such as sedatives or tranquilizers) while using brompheniramine, as it may increase the risk of sedation and other side effects.
  • Allergic Reactions: If you experience signs of an allergic reaction, such as rash, itching, swelling, dizziness, or difficulty breathing, seek immediate medical attention and discontinue use of brompheniramine.

Always consult your healthcare provider or pharmacist for personalized advice regarding the use of brompheniramine, especially if you have any concerns or questions about its safety or potential interactions with other medications or medical conditions.

What special dietary instructions should I follow?

Regarding special dietary instructions, there are no specific dietary restrictions associated with brompheniramine. However, it’s always a good idea to maintain a balanced diet and stay hydrated, especially if you are experiencing symptoms like nasal congestion or a runny nose.

What should I do if I forget a dose?

If you forget to take a dose of brompheniramine, take it as soon as you remember. However, if it’s almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you’re unsure about what to do, consult your healthcare provider or pharmacist for advice.

What side effects can this medication cause?

Brompheniramine, like any medication, can cause side effects, although not everyone experiences them. Common side effects may include:

  • Blurred vision
  • Dry mouth, nose, or throat
  • Constipation
  • Upset stomach
  • Difficulty urinating (especially for men with prostate problems)
