What does Bromfed DM syrup have in it?

Bromfed DM syrup is an over-the-counter cough medicine used to treat symptoms associated with the common cold and allergies. The active ingredients in Bromfed DM syrup are dextromethorphan hydrobromide, guaifenesin, and phenylephrine hydrochloride.

Quick answers

– Bromfed DM syrup contains the active ingredients dextromethorphan hydrobromide, guaifenesin, and phenylephrine hydrochloride.

– Dextromethorphan is a cough suppressant that works by inhibiting cough reflexes in the brain.

– Guaifenesin is an expectorant that helps loosen mucus and bronchial secretions to make coughs more productive.

– Phenylephrine is a nasal decongestant that constricts blood vessels in the nasal passages to relieve congestion.

Active ingredients in Bromfed DM

The three active ingredients in Bromfed DM syrup work together to treat multiple symptoms associated with colds, allergies, and upper respiratory infections.

Dextromethorphan hydrobromide

Dextromethorphan hydrobromide is an antitussive, meaning it suppresses coughing. It is one of the most common cough suppressing ingredients found in over-the-counter cold and cough medicines.

Dextromethorphan works by inhibiting cough reflexes in the brain. It targets the part of the brain that triggers the body’s urge to cough. When taken as directed, dextromethorphan reduces the frequency and severity of a cough.

The typical adult dose of dextromethorphan hydrobromide in cough syrup is 10-30 mg taken every 4-6 hours. No more than 120 mg should be taken in 24 hours.

Some common side effects of dextromethorphan include:

– Drowsiness
– Dizziness
– Nausea
– Vomiting
– Stomach pain
– Constipation
– Headache
– Euphoria

Dextromethorphan should not be taken by people with certain medical conditions or people taking certain medications. Conditions that may interact with dextromethorphan include:

– Liver or kidney disease
– Chronic obstructive pulmonary disease (COPD)
– Emphysema
– Asthma
– Whooping cough
– Seizures


Guaifenesin is an expectorant, meaning it helps loosen congestion in the airways and lungs to make coughs more productive. It works by thinning the mucus secretions in the airways, making it easier to cough up phlegm.

Guaifenesin has an antitussive effect in some individuals, meaning it may also suppress the urge to cough. However, its primary mechanism is as an expectorant.

The typical guaifenesin dose in cough syrup for adults is 100-400 mg taken every 4 hours as needed. No more than 2.4 grams should be consumed per day.

Potential side effects of guaifenesin may include:

– Nausea
– Vomiting
– Stomach pain
– Diarrhea
– Dizziness
– Rash
– Headache

Guaifenesin is considered safe for most adults when used as directed. It should be avoided by people with certain medical conditions, such as:

– Kidney stones
– Uric acid kidney stones
– Gastric ulcers

Phenylephrine hydrochloride

Phenylephrine hydrochloride is a nasal decongestant used to relieve congestion and sinus pressure associated with colds, allergies, and upper respiratory infections.

It works by constricting the blood vessels in the nasal passages, reducing swelling and congestion in the sinus cavities. This helps open up the airways and allows for easier breathing.

The typical phenylephrine dose for adults in cough and cold medicines is 5-10 mg every 4 hours as needed. No more than 40 mg should be taken in 24 hours.

Potential side effects of phenylephrine include:

– Increased blood pressure
– Anxiety
– Dizziness
– Restlessness
– Difficulty sleeping
– Upset stomach

People who should use phenylephrine with caution or avoid it altogether include those with:

– High blood pressure
– Heart disease
– Diabetes
– Glaucoma
– Prostate issues

Uses and benefits of Bromfed DM

Bromfed DM syrup is formulated to provide relief from multiple cold and allergy symptoms with the combination of the three active ingredients. Here are the main uses and benefits of this cough syrup:

Relieving coughs

The dextromethorphan in Bromfed DM suppresses the urge to cough, while the guaifenesin loosens mucus. Together, they can provide short-term relief for coughing caused by minor viral infections, allergies, or inhaled irritants.

Thinning mucus

The expectorant properties of guaifenesin help thin the mucus secretions in the chest and sinuses. This makes coughs more productive in expelling phlegm and mucus.

Clearing nasal congestion

By constricting blood vessels in the nasal passages, the phenylephrine in Bromfed DM helps open up sinus cavities and relieve congestion and pressure. This makes breathing easier.

Alleviating allergy symptoms

Bromfed DM can provide relief from coughing, congestion, runny nose, and postnasal drip caused by indoor and outdoor allergies. The combination of ingredients addresses multiple allergy symptoms.

Treating symptoms of the common cold

For upper respiratory symptoms associated with the common cold, Bromfed DM can suppress coughs, loosen phlegm, and clear nasal congestion to provide temporary relief.

Dosage and administration

It is important to follow the recommended dosage guidelines when taking Bromfed DM syrup:


– Adults and children 12 years and over: Take 20 mL every 4 hours. Do not exceed 6 doses in 24 hours.

– Children under 12 years: Do not use, consult a pediatrician.

Route of administration

Bromfed DM is taken orally by mouth. A dosing cup with measurements is included in the packaging.

The syrup should be measured to the correct dose amount and swallowed. For best results, avoid taking with food or milk as this can reduce absorption.

Duration of use

Bromfed DM should only be used for short periods of time to relieve acute cough and cold symptoms. It is meant for temporary relief and should not be used for more than 1 week unless directed by a doctor.

Prolonged use can lead to nasal congestion rebound and medication overuse headaches upon discontinuation. Seek medical advice if symptoms persist beyond 1 week or return after treatment.

Warnings and precautions

Bromfed DM syrup is generally safe when used occasionally as directed in healthy adults and children over 12 years old. However, there are some warnings and precautions to be aware of:

Age restrictions

Children under 12 years should not use Bromfed DM. Dextromethorphan use in young children has been associated with serious side effects.

Drug interactions

Bromfed DM may interact with certain prescription medications. These include antidepressants, anxiety medications, and cough suppressants containing dextromethorphan.

Medical conditions

People with high blood pressure, heart disease, diabetes, glaucoma, asthma, enlarged prostate, or urinary retention issues should consult a doctor before use. Bromfed DM can exacerbate these conditions.


Bromfed DM contains dextromethorphan which some people may be sensitive to. It also contains alcohol, fructose, and sodium benzoate.

Pregnancy and breastfeeding

Bromfed DM has not been studied for safety during pregnancy or breastfeeding. Usage is not recommended unless a doctor advises it.

Side effects

When taken occasionally as directed, Bromfed DM is generally well-tolerated. However, some side effects are possible:

Common side effects

– Drowsiness
– Dizziness
– Nausea
– Constipation
– Stomach pain
– Headache
– Nervousness

These tend to be mild and temporary. But if any persist or become severe, discontinue use.

Rare serious side effects

Rarely, serious side effects may occur with dextromethorphan overdose or abuse:

– Seizures
– Respiratory depression
– Psychosis
– Liver damage

Seek immediate medical attention if any serious side effects develop.


Taking too much Bromfed DM can result in dextromethorphan overdose. Symptoms may include:

– Agitation
– Confusion
– Vomiting
– Seizures
– Coma

An overdose can be fatal. Seek emergency help if an overdose is suspected. Do not take more than the recommended Bromfed DM dosage.

Abuse potential

Dextromethorphan (DXM) contained in Bromfed DM has the potential for recreational abuse. High doses can produce dissociative effects and hallucinations.

Seeking euphoria through Bromfed DM abuse can have dangerous health consequences like psychosis, organ damage, and death. Do not attempt to get high with this medicine.


There are some alternatives to consider if you want to relieve cold and cough symptoms but prefer not to use Bromfed DM:

Guaifenesin-only products

Single-ingredient guaifenesin expectorant syrups, such as Mucinex, can help thin mucus without suppressing coughs. This may be preferable for those trying to get phlegm out of their airways.

Phenylephrine-only nasal sprays

Nasal decongestant sprays with phenylephrine, such as Afrin, can relieve congestion symptoms without the other ingredients in Bromfed DM.

Cough drops and throat lozenges

For mild or intermittent coughing, cough drops and throat lozenges can provide relief without medication side effects. Products containing menthol, honey, or glycerin work to coat and soothe irritated throat and airway tissues.

Saline sprays and washes

Saline solutions made for rinsing the sinuses can thin out mucus while providing moisturization. This helps clear congestion and allows drainage.

Vapor rubs

Mentholated vapor rubs like Vicks VapoRub can relieve congestion when applied to the chest and throat area. Inhaling the vapors can help open nasal passages.

Hot drinks

Sipping on hot tea, coffee, or broth provides hydration and may help soothe a cough or runny nose. The steam can also help clear congestion.


Using a humidifier adds moisture to the air, which can ease coughs and provide sinus relief. Keeping nasal passages hydrated makes it easier to expel mucus.


Bromfed DM syrup for cough and cold relief contains a combination of the medications dextromethorphan, guaifenesin, and phenylephrine. When used as directed, it can temporarily alleviate symptoms like coughing, congestion, and mucus production associated with minor viral illnesses, allergies, and sinusitis. However, side effects are possible, particularly when exceeding dosage guidelines. Bromfed DM should be used with caution and only for short periods of time unless otherwise advised by a doctor. Alternative therapies may be preferable for those wanting to avoid medication side effects or interactions. But when used responsibly, Bromfed DM can provide effective short-term relief from coughs, congestion, and upper respiratory discomfort.
