Chlorpheniramine Maleate Side Effects

allergy medication

What side effects can be expected when taking chlorpheniramine maleate? Will it make me drowsy or affect my blood pressure?

Chlorpheniramine maleate is a first generation antihistamine or allergy medication. It blocks the effect of histamine in the body, which reduces the symptoms from allergies. It is most effective if taken before exposure to allergens.

The most common side effects include: drowsiness, dizziness, slowed reaction time, headache, constipation, difficulty urinating, drop in blood pressure, blurred vision, increased heart rate and sweating.Chlorpheniramine maleate side effects

Drowsiness does seem to be the most common side effect. Some people just use this allergy medication at night and use the drowsiness to their advantage.  It can also thicken lung secretions, and many people have good luck using it to reduce coughing from post nasal drip. Taking the proper dosage or even reducing the dosage can reduce the chance of side effects.

Those with glaucoma, asthma, COPD, difficulty urinating, bowel obstructions and prostate problems should talk to a doctor prior to using this medication. Even though this medication can be purchased without a prescription, side effects can and do occur. I’ve seen many people take chlorpheniramine without incident, however, if you are uncertain, be sure to speak with a doctor or pharmacist first.
