About Dimetapp – What is it?
Dimetapp, which is commonly known as Dimetapp Cold & Allergy is a medication that is made from a combination of two substances; brompheniramine and phenylephrine.1https://www.dimetapp.com/products/
Dimetapp belongs to a drug class known as upper respiratory combinations which are products that may contain one or more medicines, which relieve cough, act as decongestants or relieve allergy or hay fever symptoms.
Dimetapp also belongs to the Antihistamine + antitussive + sympathomimetic drug class.
Dimetapp is mainly for children aged 6–12 years of age and above, and it is normally prescribed by the doctor for colds, allergies, coughs, flu, and night-time congestion (nasal).
Constituents or Ingredients of Dimetapp
As mentioned earlier, Dimetapp is made up of two substances, which are:
- Brompheniramine: An antihistamine that reduces the effects of the natural chemical, histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
- Phenylephrine: A decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

How Does Dimetapp Work?
Dimetapp is usually prescribed by doctors for colds, allergies, and nasal congestion because it works by inducing an antihistamine effect to reduce histamine levels since histamine is responsible for symptoms of colds and allergies.
It also works to inhibit nasal congestion by shrinking dilated blood vessels in the nasal passages because dilated blood vessels can lead to nasal congestion.
Dimetapp Dosage – How to Use Dimetapp
If you are taking the over-the-counter product, read all directions on the product package before taking this medication. If you have any questions, consult your pharmacist. If your doctor has prescribed this medication, take it as directed.
Take this medication by mouth with or without food with a full glass of water (8 ounces or 240 milliliters) or as directed by your doctor. This medication may be taken with food or milk if stomach upset occurs.
Use Dimetapp exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Cold medicine is usually taken only for a short time until your symptoms clear up.
Do not give Dimetapp Cold & Allergy to a child younger than 4 years old. Always ask a doctor before giving a cough or cold medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.
Measure Dimetapp Cold & Allergy with a special dose-measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
If you are using the liquid form, use a medication measuring device to carefully measure the prescribed dose. Do not use a household spoon. If your liquid form is a suspension, shake the bottle well before each dose.
If you are taking the extended-release capsules, swallow them whole. Do not crush or chew extended-release capsules or tablets. Doing so can release all of the drugs at once, increasing the risk of side effects.
Also, do not split extended-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
Chewable forms of this medication should be chewed thoroughly before swallowing.2https://www.webmd.com/drugs/2/drug-144117/dimetapp-dm-cold-cough-pe-oral/details If you are taking the powder, mix it thoroughly in the proper amount of liquid and stir well. Drink all of the liquid right away. Do not prepare a supply for future use.
The dosage is based on your age, medical condition, and response to therapy. If you are taking this medication for allergy or hay fever symptoms, take it regularly in order to get the most benefit from it.
Improper use of this medication (abuse) may result in serious harm (such as brain damage, seizure, and death). Do not increase your dose, take it more frequently, or use it for a longer time than directed.
Tell your doctor if your condition lasts or gets worse. Call your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache, cough, or skin rash.

Benefits of Taking Dimetapp
Dimetapp is beneficial, as it is used to treat symptoms caused by the common cold, flu, allergies, hay fever, or other breathing illnesses (such as sinusitis, and bronchitis).
Dimetapp also acts as a cough suppressant that affects a certain part of the brain (cough center), reducing the urge to cough.
It helps relieve stuffy nose symptoms, and relieve watery eyes, itchy eyes/nose/throat, runny nose, and sneezing.
Side Effects of Taking Dimetapp
Drowsiness, dizziness, headache, blurred vision, upset stomach, nausea, constipation, or dry mouth/nose/throat may occur. If any of these effects last or get worse, notify your doctor or pharmacist promptly.
To relieve dry mouth, suck on (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute. Dimetapp can dry up and thicken mucus in your lungs, making it more difficult to breathe and clear your lungs. To help prevent this effect, drink plenty of fluids unless otherwise directed by your doctor.
To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. If your doctor has prescribed this medication, remember that your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including mental/mood changes (such as confusion, hallucinations), ringing in the ears, shaking (tremors), trouble urinating, weakness, easy bruising/bleeding, fast/slow/irregular heartbeat, or seizure.
