Common Side Effects of OTC Medications in Kenya – What You Need to Know Before Your Next Dose

Introduction: Don't Let That "Simple" Pill Surprise You

Over-the-counter (OTC) medications are a staple in most Kenyan homes. Whether it's for headaches, colds, allergies, or minor pains, OTC drugs offer quick relief, no prescription needed.

But while they're convenient and accessible, they're not without risk.

Many people assume OTC medicines are completely harmless. Unfortunately, improper use or combining medications without guidance can lead to unwanted side effects, some mild, others potentially serious.

In this guide, we'll explore the common side effects of OTC medications in Kenya, explain how to avoid adverse reactions, and share how Zuri Health can help you make safer choices.

What Are OTC Medications?

OTC medications are drugs that you can buy without a doctor's prescription. In Kenya, they are available in pharmacies, supermarkets, and even small local shops.

Popular examples include:

• Paracetamol (Panadol) – for fever and mild pain
• Ibuprofen (Brufen) – for inflammation and menstrual pain
• Antihistamines (Piriton, Cetirizine) – for allergies and colds
• Antacids (Eno, Gaviscon) – for heartburn and indigestion
• Cough syrups – for dry or productive cough
• Multivitamins – for general wellness

While helpful when used correctly, these medications can cause side effects, especially when misused or overused.
