If your prescription label says Bromphen-PSE-DM, Brom PSE DM SYP, or Bromphen-PSE-DM 2-30-10mg, it usually refers to a combination cough and cold syrup. The name looks confusing, but each part stands for one ingredient.
Bromphen means brompheniramine, an antihistamine.
PSE means pseudoephedrine, a nasal decongestant.
DM means dextromethorphan, a cough suppressant.
SYP usually means syrup.
So, if you are asking what is Brom PSE DM SYP, the simple answer is: it is a prescription cough, cold, and allergy syrup used for symptoms like cough, stuffy nose, runny nose, sneezing, and upper respiratory congestion.
Cleveland Clinic describes brompheniramine, pseudoephedrine, and dextromethorphan oral solution as a combination of an antihistamine, cough suppressant, and decongestant used for symptoms of the common cold, allergies, or flu.
Quick Answer: What Is Bromphen PSE DM?
Bromphen-PSE-DM is a 3-in-1 medicine for cough and upper respiratory symptoms. It is commonly prescribed when a person has cold or allergy symptoms with a cough and nasal congestion.
The standard Bromphen-PSE-DM 2-30-10mg strength means each 5 mL teaspoonful contains:
| Ingredient | Amount in 5 mL | What It Does |
| Brompheniramine maleate | 2 mg | Helps allergy-type symptoms like runny nose and sneezing |
| Pseudoephedrine HCl | 30 mg | Helps nasal and sinus congestion |
| Dextromethorphan HBr | 10 mg | Helps suppress cough |
DailyMed lists this syrup as containing brompheniramine 2 mg, pseudoephedrine 30 mg, and dextromethorphan 10 mg per 5 mL.
What Is Bromphen PSE DM Used For?
If you are asking what is Bromphen PSE DM used for, it is mainly used for coughs and upper respiratory symptoms linked with a cold or allergies.
It may be prescribed for:
Cough
Nasal congestion
Sinus congestion
Runny nose
Sneezing
Watery or itchy eyes
Cold symptoms
Allergy symptoms
DailyMed says brompheniramine, pseudoephedrine, and dextromethorphan syrup is indicated for relief of coughs and upper respiratory symptoms, including nasal congestion, associated with allergy or the common cold.
How Each Ingredient Works
This medicine works because the three ingredients target different symptoms.
Brompheniramine is an antihistamine. It helps dry up allergy-type symptoms such as runny nose, sneezing, and watery eyes. It may also cause drowsiness because older antihistamines can affect alertness.
Pseudoephedrine is a decongestant. It works by narrowing swollen blood vessels in the nasal passages, which can make breathing through the nose easier. DailyMed notes that pseudoephedrine’s nasal decongestant effect is related to vasoconstriction of dilated nasal arterioles.
Dextromethorphan is a cough suppressant. It acts in the brain to raise the cough threshold, which can reduce the urge to cough. DailyMed states that dextromethorphan acts centrally to elevate the threshold for coughing.
Bromphen-PSE-DM 2-30-10mg Dosage
The phrase Bromphen PSE DM 2-30-10mg dosage usually refers to the syrup strength, not one full dose by itself. The common strength is 2 mg / 30 mg / 10 mg per 5 mL.
DailyMed gives this dosing schedule for one brompheniramine-pseudoephedrine-dextromethorphan syrup label:
| Age Group | Listed Dose |
| Adults and children 12 years and older | 10 mL every 4 hours |
| Children 6 to under 12 years | 5 mL every 4 hours |
| Children 2 to under 6 years | 2.5 mL every 4 hours |
| Infants 6 months to under 2 years | Dosage must be established by a physician |
The same label says do not exceed 6 doses in 24 hours.
Do not use this table as a reason to self-dose a child. For children, follow the exact prescription label or ask a pediatrician or pharmacist. Cough and cold medicines can be risky in young children, especially if the dose is guessed.
Is Bromphen-PSE-DM a Controlled Substance?
A common question is is Bromphen PSE DM a controlled substance? In the usual U.S. legal meaning, Bromphen-PSE-DM is not typically treated like opioid cough syrups such as codeine products, but it is still a prescription medication in many formulations.
DailyMed labels this brompheniramine, pseudoephedrine, and dextromethorphan oral solution as “Rx only.”
The DM ingredient, dextromethorphan, is not controlled under the federal Controlled Substances Act according to the DEA’s dextromethorphan information. However, pseudoephedrine is regulated because it can be used illegally to make methamphetamine. FDA explains that medicines containing pseudoephedrine are kept behind the counter for OTC sales, monthly purchase amounts are limited, and buyers may need photo identification.
So the plain answer is:
Bromphen-PSE-DM is not usually a DEA-controlled narcotic, but it may be prescription-only, and its pseudoephedrine ingredient is legally regulated.
Is Bromphen-PSE-DM the Same as Bromfed DM?
Many people use Bromphen-PSE-DM and Bromfed DM as similar terms because Bromfed DM is a brand name associated with this combination. Generic bottles may simply list the ingredients instead of a brand name.
The names may look different on labels:
Bromphen-PSE-DM
Brompheniramine / Pseudoephedrine / Dextromethorphan
Bromfed DM
Brom PSE DM SYP
Bromphen-PSE-DM 2-30-10mg/5mL
Always check the active ingredients and strength because not every cough syrup has the same formula.
Common Side Effects
Because this medicine combines three ingredients, side effects can come from any part of the formula.
Common side effects may include:
Drowsiness
Dizziness
Dry mouth, nose, or throat
Thickened mucus
Nervousness
Trouble sleeping
Nausea
Upset stomach
Constipation or diarrhea
Fast heartbeat or palpitations
DailyMed lists the most frequent adverse reactions as sedation, dryness of mouth, nose and throat, thickening of bronchial secretions, and dizziness, with other possible effects involving the skin, heart, nervous system, urinary system, stomach, and breathing.
Who Should Be Careful With This Medicine?
Bromphen-PSE-DM is not right for everyone. You should tell your doctor or pharmacist about your health history before taking it.
Extra caution may be needed if you have:
High blood pressure
Heart disease
Diabetes
Thyroid disease
Glaucoma
Asthma or chronic lung disease
Trouble urinating or prostate problems
Severe coronary artery disease
A cough with a lot of mucus
A long-term cough from smoking, asthma, emphysema, or COPD
DailyMed says the syrup should be used with caution in people with bronchial asthma, narrow-angle glaucoma, gastrointestinal obstruction, urinary bladder neck obstruction, diabetes, hypertension, heart disease, or thyroid disease. It also says not to use it in patients with severe hypertension or severe coronary artery disease.
Important Drug Interactions
One of the biggest warnings involves MAO inhibitors, a type of medicine used for depression, Parkinson’s disease, and other conditions.
Do not take Bromphen-PSE-DM if you have used an MAOI recently unless your doctor specifically says it is safe. DailyMed warns that serious reactions, including hyperpyrexia, hypotension, and death, have been reported when MAOIs are taken with products containing dextromethorphan, and it says the combination should be avoided.
Also be careful with:
Alcohol
Sleeping pills
Anxiety medicines
Sedatives
Other antihistamines
Other decongestants
Other cough medicines with dextromethorphan
Blood pressure medicines
Brompheniramine can add to drowsiness from alcohol and sedatives, while pseudoephedrine may work against some blood pressure medicines. DailyMed notes that antihistamines can have additive effects with alcohol and CNS depressants, and sympathomimetics may reduce the effects of antihypertensive drugs.
Can It Make You Sleepy?
Yes. Brompheniramine can cause drowsiness and reduce mental alertness. This is why you should be careful with driving, machinery, school, work, or anything that requires focus until you know how it affects you.
DailyMed warns patients about activities requiring mental alertness, such as driving or operating dangerous machinery.
Can It Make You Hyper?
It can. Although antihistamines often make adults sleepy, some children may become excited, restless, or unusually active. Pseudoephedrine can also cause nervousness, fast heartbeat, or insomnia in some people.
This is one reason dosing children needs extra care and should follow the prescriber’s instructions exactly.
Pregnancy and Breastfeeding
If you are pregnant, planning pregnancy, or breastfeeding, ask your healthcare provider before using this medicine.
DailyMed says it is not known whether this combination can cause fetal harm and that it should be given to a pregnant woman only if clearly needed. The same label states that it is contraindicated in nursing mothers because of higher intolerance risk of antihistamines in small infants, especially newborns and premature infants.
What If You Miss a Dose?
If this medicine was prescribed on a schedule and you miss a dose, follow the instructions from your doctor or pharmacist. In many cough-and-cold situations, it is taken only when needed for symptoms.
Do not double up to “catch up.” Taking too much can increase the risk of drowsiness, fast heartbeat, high blood pressure, agitation, confusion, breathing problems, or overdose symptoms.
Signs of Overdose or Serious Reaction
Get medical help quickly if someone takes too much or develops serious symptoms.
Warning signs may include:
Severe drowsiness
Confusion
Hallucinations
Seizures
Very fast heartbeat
Severe dizziness
Trouble breathing
Severe agitation
Very high blood pressure symptoms
Blue lips or extreme weakness
DailyMed warns that overdose effects may include CNS depression or stimulation, anticholinergic effects, tachycardia, hypertension, cardiac arrhythmias, drowsiness, ataxia, and convulsive seizures.
Storage Tips
Store the medicine exactly as the label says. DailyMed lists storage at 20°C to 25°C, keeping the bottle tightly closed and dispensing it in a tight, light-resistant container.
Also keep it away from children. Cough syrups can be dangerous if a child drinks from the bottle or receives an incorrect dose.
When to Call a Doctor
Call your doctor or pharmacist if:
The cough lasts more than a few days
Symptoms are getting worse
Fever is high or persistent
You have shortness of breath or wheezing
You have chest pain
You cough up blood
You have severe dizziness or fast heartbeat
A child becomes unusually sleepy, agitated, or confused
You are not sure about the dose
Also ask before using it with other cold, flu, allergy, or sleep medicines because many products contain overlapping ingredients.
