Chlorpheniramine is used to relive itchy, red, watery eyes, itchy nose and throat, sneezing, running nose due to allergies, common cold and hay fever. Chlorpheniramine is not used for treatment of cold and allergy symptoms, but it helps to control tem. Its generic name is Chlorpheniramine maleate. Here is some insight into this medication.
Basically Chlorpheniramine is an antihistamine. During an allergic reaction, the body produces histamine and this medication blocks it. It also blocks another substance produced by the body (acetylcholine). By doing so, it helps dry some fluid producing symptoms like runny nose and watery eyes.
Keenly follow the instructions for your dosage to avoid getting serious side effects. Since Chlorpheniramine maleate causes drowsiness, do not use it to make a child sleep. This is drug abuse. Make sure you do not administer another cold and cough medication with similar ingredients. Consult a doctor or pharmacist on other ways to control the symptoms. Some include drinking lots of water, saline nose drops or spray.
Inform the pharmacist or doctor of any medications you might be taking. Do not forget to include vitamin, mineral and any other nutritional supplements. Make sure you mention narcotic painkillers, cold medications, anxiety medication, depression medication, sedatives, muscle relaxants, hay fever medication and sleeping pills or tranquilizers.
Inform the doctor if you have had a history of asthma, chronic bronchitis, emphysema or any other form of lung infection, glaucoma, diabetes, ulcers, enlarged prostate, high blood pressure, heart disease, over reactive thyroid gland or seizures.
Inform the doctor of an existing pregnancy or a planned pregnancy if you are breastfeeding or get pregnant during the dose.
If you are to undergo any form of surgery, you need to inform the surgeon that you are taking this medication.
It causes drowsiness so avoid driving or operating machinery.
Consult your doctor about consuming alcohol. Alcohol could worsen the side effects.
If you get this medication over the counter, read all the instructions on the leaflet. If you do not understand, ask the pharmacist for clarification. If the doctor has prescribed the medication, then follow the prescription to the letter.
The liquid, capsule or tablet can be taken with food or without as per the dosage that is recommended. If the medication gives you stomach upsets, you can take it with milk or food.
If the drug is contained in an extended release capsule, then swallow it whole. Avoid crushing it or chewing it as this might worsen the side effects because of releasing the drug at once. If the tablet has a score line, you can break it if the doctor approves of it. Otherwise, do not break the capsule or the tablet.

Other products like long acting capsules/tablets are also not recommended for children below the age of 12. Before using such medication, ask a pediatrician for further advice.
