Chlorpheniramine
CHLORPHENIRAMINE
Overview
Chlorpheniramine is commonly used to treat runny nose, sneezing, itchy eyes, watery eyes, and skin reactions caused by allergies, colds, or hay fever. It’s one of the older antihistamines and may cause drowsiness.
Classification
Antihistamine
Uses
Seasonal allergies (like pollen)
Dust or pet allergies
Cold-related symptoms such as sneezing or runny nose
Skin allergies, including hives or itchy rashes
How It Works
When your body comes in contact with allergens (like dust or pollen), it releases histamine, which causes symptoms like sneezing or itching. Chlorpheniramine blocks histamine, helping to relieve those symptoms and make you feel more comfortable.
Dosage
As prescribed by your doctor.
Side effects
Some common side effects may include:
Drowsiness or feeling sleepy
Dry mouth, nose, or throat
Dizziness or lightheadedness
Upset stomach
Blurred vision (in some cases)
Precautions
Use caution if you need to drive or operate machines, as it may cause drowsiness.
Avoid alcohol, which can increase sleepiness.
Let your doctor know if you have conditions like glaucoma, asthma, enlarged prostate, or urinary problems.
If you’re pregnant, breastfeeding, or giving it to a child or elderly person, consult a healthcare provider first.
Don’t take more than the recommended dose, as too much can increase side effects.

Phenylephrine
PHENYLEPHRINE
Overview
Phenylephrine is a medicine often used to relieve a stuffy or blocked nose. It works by shrinking swollen blood vessels in your nasal passages, helping you breathe more easily. You might find it in many cold, flu, or allergy medications.
Classification
Decongestants
Uses
Relieves nasal congestion due to colds, allergies, or sinus infections
Sometimes used to increase low blood pressure during surgery or in critical care
May be found in eye drops to dilate pupils during eye exams
How It Works
Phenylephrine works by narrowing the blood vessels in the nose. This reduces swelling and opens up your airways. When taken for blood pressure support, it tightens blood vessels throughout the body, which helps raise blood pressure.
Dosage
As prescribed by your doctor.
Side effects
Some common or possible side effects may include:
Headache
Dizziness
Nervousness or restlessness
Trouble sleeping (insomnia)
Increased heart rate or blood pressure
In rare cases, serious side effects like irregular heartbeat or chest pain can occur. Always report unusual symptoms to your doctor.
Precautions
Avoid it if you have high blood pressure, heart disease, thyroid problems, or glaucoma, unless your doctor says it’s safe.
Do not use more than the recommended dose – overuse can increase side effects.
Tell your doctor if you’re pregnant or breastfeeding before using.
If taken with other medications (especially for depression or blood pressure), it could interact negatively.
Not recommended for young children without medical advice.
