Caffeine

CAFFEINE

Overview:

Caffeine is a natural substance that helps you feel less tired and more awake. You’ll find it in things like coffee, tea, cola, energy drinks, and even in some medications.

Classification: Central nervous system stimulants

Uses:
Fights sleepiness and helps keep you focused

Can help you stay mentally sharp during the day

Often added to pain relievers to make them work better (like in migraine treatment)

Sometimes used in newborns (especially premature babies) to help with breathing problems

How it works:
Caffeine helps you stay awake and focused by blocking a brain chemical called adenosine, which normally makes you feel drowsy.
By stopping adenosine, caffeine keeps your brain more active, helping you feel energized, alert, and a bit more awake. It can also slightly increase your heart rate and make you feel more awake physically and mentally.

Dosage: As prescribed by your doctor.

Side effects:
Having too much caffeine might cause:
Restlessness or shaky hands

Trouble falling asleep

Rapid heartbeat or a racing pulse

Stomach discomfort or acidity

Mild headaches, especially if you suddenly stop using it

Frequent urination

Feeling uneasy or anxious

Precautions:
Don’t have too much: Taking in large amounts of caffeine can make you feel nervous, interfere with sleep, or cause a fast heartbeat. It’s best to keep it moderate—about 1 to 3 cups of tea or coffee a day is usually safe.

If you’re sensitive, go slow: Some people react strongly to even small doses of caffeine, causing shakiness, headaches, or discomfort.

Avoid it before bedtime: Since caffeine keeps you alert, having it too late in the day (especially after the afternoon) can make it hard to fall asleep.

Pregnant or breastfeeding? Talk to your doctor. Too much caffeine might affect your baby, so it’s safer to limit your intake.

If you have heart issues, anxiety, or high blood pressure: Be careful—caffeine can sometimes worsen these problems.

Check food and medicine labels: Caffeine isn’t only in coffee—it’s also found in soft drinks, energy drinks, chocolate, and some pills like pain relievers or slimming products.

Chlorpheniramine Maleate

CHLORPHENIRAMINE MALEATE 

Overview:

Chlorpheniramine Maleate is an antihistamine medicine that helps reduce allergy symptoms like sneezing, runny nose, itchy or watery eyes, and hives. It works by blocking histamine, a chemical in the body that causes allergic reactions. Doctors commonly use it for allergic rhinitis, hay fever, urticaria, and other mild allergic conditions.It is available as tablets, syrups, and injections.

Classification: First-generation antihistamine

Uses:

• Relieves allergy symptoms like sneezing, runny nose, and itchy eyes
• Treats hay fever (allergic rhinitis)
• Sometimes used for cold symptoms like runny nose
• Reduces itching from insect bites or mild allergic reactions
• Helps with hives (urticaria) and skin rashes

How it works:

Chlorpheniramine Maleate works by blocking histamine, the chemical that causes allergy symptoms like sneezing, runny nose, itching, watery eyes, and rashes. By preventing histamine from attaching to H1 receptors, it reduces allergic reactions and helps you feel more comfortable. It may cause mild drowsiness because it can also affect the brain.

Dosage: As prescribed by your doctor.

Side Effects:

• Drowsiness or sleepiness
• Dry mouth, nose, or throat
• Dizziness or headache
• Nausea or mild stomach upset
• Blurred vision (rare)
• Excitability or restlessness in some children

Precautions:

Chlorpheniramine helps with allergies but should be used carefully. Avoid it if you’re allergic, and pregnant or breastfeeding women should only use it if advised by a doctor. Kids and older adults may get sleepy, and people with glaucoma, asthma, heart problems, or urinary issues should be cautious. It can cause drowsiness or dizziness, so avoid driving or operating machinery.

Paracetamol

PARACETAMOL

Overview

Paracetamol is a commonly used medication that helps relieve mild to moderate pain and reduce fever. It’s often used for:

Headaches

Toothaches

Muscle and back pain

Menstrual cramps

Cold and flu symptoms

It’s available over-the-counter and is considered safe when used as directed.

Classification

Analgesic and antipyretic agent

Uses

Paracetamol is used for pain relief and fever. It is used to relieve pain in conditions like headache, muscle pain, or dental pain.

How it works

When you produce a fever, your body’s internal thermostat — found in the hypothalamus portion of the brain — is raised to a higher temperature. This new set point is usually induced by pyrogens (substances made during infections) that tell the body to produce more heat as a form of immune defense.

Due to its effects in the brain, paracetamol reduces the production of reactive prostaglandins. Prostaglandins are disease-fighting chemicals released during infection that in turn, raise the body’s temperature set point. By decreasing prostaglandin levels, paracetamol enables the hypothalamus’ temperature control centre to bring the body’s temperature back down to normal, allowing the body to cool down and the fever to subside

Dosage

As directed by the physician

Precautions

Most people can take paracetamol safely, including:

pregnant women

breastfeeding women

children over 2 months of age – lower doses are recommended for young children

Phenylephrine Hydrochloride

PHENYLEPHRINE HYDROCHLORIDE

Overview

Phenylephrine is a nasal decongestant used to temporarily relieve nasal discomfort caused by colds, allergies, and hay fever. It works by reducing swelling in the nasal passages, making it easier to breathe. However, it does not address the underlying cause of the symptoms or speed up recovery

Classification
Nasal decongestants

Uses

Oral and nasal phenylephrine are used as nasal decongestants to temporarily unblock a nose or relieve sinus pressure in people with nasal and sinus congestion caused by colds, allergies, or hay fever. While phenylephrine can provide some symptom relief, it doesn’t treat the underlying cause or speed recovery

How it works

Phenylephrine Hydrochloride is a sympathomimetic amine used as a topical decongestant, systolic vasopressor, and mydriatic agent. Its mechanism of action works through various pathways with the mechanism of action primarily based on its ability to stimulate alpha-adrenergic receptors, particularly alpha-1 receptors, which are involved in vascular smooth muscle contraction.

Dosage

As directed by the physician
