Why is this medication prescribed?

Brompheniramine treats allergies, hay fever, and the common cold by easing symptoms such as runny nose, itchy, watery eyes, and sneezing. Brompheniramine helps control symptoms, but does not treat the cause of the symptoms or speed recovery. Children shouldn’t be given brompheniramine to make them sleepy. The drug brompheniramine belongs to the antihistamine drug class. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

How should this medicine be used?

Brompheniramine comes in combination with other cough and cold medications as a chewable tablet, an extended-release (long-acting) capsule, an extended-release (long-acting) tablet, and a liquid to be taken by mouth. The chewable tablet and liquid are usually taken every 4 to 6 hours as needed. The extended-release tablets and capsules are usually taken every 8 or 12 hours as needed. Pay close attention to the instructions on the package label or the label on your prescription, and ask your doctor or pharmacist to clarify any instructions you do not understand. Take brompheniramine exactly as directed. Never take it in larger or less amounts or more frequently than recommended on the box label or by your doctor.

Brompheniramine comes in combination with other cough and cold medications. Find out which product is best for your symptoms by consulting your doctor or pharmacist. Before taking two or more non-prescription cough and cold medications at the same time, carefully read the labels. If you take these products together, you might experience an overdose because they might both contain the same active ingredient. This is especially important if you will be giving cough and cold medications to a child.

Brompheniramine-containing over-the-counter cough-and-cold remedies, in particular, have the potential to be fatal to young children. Do not give these products to children younger than 6 years of age. If you provide these goods to youngsters 6-11 years of age, use caution and follow the packaging guidelines carefully.

Be sure the product is appropriate for a child of that age by carefully reading the package label before feeding a child a product that includes brompheniramine. Products containing brompheniramine intended for adults should not be given to children.

Check the package label before giving a child a product containing brompheniramine to determine how much of the medication the child needs to take. Give the dose that matches the child’s age on the chart. Ask the child’s doctor if you don’t know how much medication to give the child.

If you are taking the liquid, do not use a household spoon to measure your dose. Use a spoon designed specifically for measuring medication, the measuring cup that came with it, or both.

If you are taking the extended-release tablets or capsules swallow them whole; do not crush, break, or chew them.

If your symptoms persist for more than 7 days or if you have a fever, stop taking brompheniramine and make an appointment with your doctor.

  • Inform your doctor and pharmacist what prescription and nonprescription drugs, vitamins, nutritional supplements, and herbal products you are taking or plan to use. Be sure to mention any of the following: monoamine oxidase (MAO) inhibitors like isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate); medications for colds, hay fever, or allergies; medications for depression or seizures; muscle relaxants; narcotic medications for pain; sedatives; sleeping pills; and tranquillizers.
  • Inform your doctor if you currently or ever had any of the following conditions: ulcers; difficulty urinating (due to an enlarged prostate gland); heart disease; high blood pressure; seizures; or an overactive thyroid gland. Glaucoma, a condition in which increased pressure in the eye can cause gradual loss of vision.
  • Inform your doctor if you are expecting, intend to become pregnant, or are nursing a baby. Call your doctor if you become pregnant while taking brompheniramine.
  • You should let your doctor or dentist know that you are taking brompheniramine if you are having surgery, including dental surgery.
  • You should know that this medication may make you drowsy. Prior to understanding how this drug affects you, avoid using machinery or driving a car.
  • See your doctor about drinking responsibly while taking brompheniramine. Drinking can exacerbate the negative effects of brompheniramine worse.

What special dietary instructions should I follow?

Unless your doctor instructs you otherwise, resume your normal diet.

What should I do if I forget a dose?

Typically, brompheniramine is consumed as needed. If your doctor has directed you to take brompheniramine regularly, take the missed dose as soon as you remember it. Nevertheless, if it is almost time for the next dose, skip the missed dose and follow your usual dosing plan. To make up for a missing dose, do not take a second one.

Brompheniramine may induce negative effects. Inform your doctor if any of these symptoms are severe or do not go away:

  • Drowsiness
  • Dry mouth, nose, and throat
  • Nausea
  • Headache
  • Chest congestion

Some side effects can be serious. Call your doctor right away if you experience any of the following symptoms:

  • Vision problems
  • Difficulty urinating

Other negative effects of brompheniramine are possible. If you have any strange side effects while taking this medicine, contact your doctor right once.

You or your doctor can submit a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting programme online or by phone if you have a serious side event (1-800-332-1088).

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).

Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at for additional information.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Moreover, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Ask any inquiries you may have regarding brompheniramine to your pharmacist.

It is vital for you to keep a documented list of all of the prescription and nonprescription (over-the-counter) drugs you are taking, as well as any items such as vitamins, minerals, or other dietary supplements. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
