If you’ve ever taken medication alongside food, alcohol, or mixed different drugs—even herbal remedies—you might not realize the risks involved. In Nigeria, it’s common to self-prescribe, whether it’s painkillers or antibiotics mixed with herbal concoctions, often without understanding the consequences. But drug interactions can make your medication less effective—or worse, lead to dangerous complications. So, why should you care about these interactions?
What are drug interactions?
Drug interactions occur when a medication’s effect changes due to alcohol, food, or other drugs you’re consuming. They can either weaken the effect of your medication or make it too strong, sometimes leading to dangerous side effects.
Why is understanding drug interactions important?
In Nigeria, we tend to self-medicate without realising that mixing drugs, herbal treatments, or alcohol can have unintended consequences. Taking medications without proper guidance could reduce their effectiveness, or even lead to severe health risks. Knowing how different substances interact ensures your treatments work as they should and helps prevent complications that could harm your health.
Types of drug interactions
- Drug-alcohol interactions: Combining alcohol with certain medications, like antibiotics or painkillers, can reduce effectiveness or increase side effects such as nausea, dizziness, or liver damage.
- Drug-drug interactions: This happens when two or more drugs react negatively with each other. For example, combining blood thinners with NSAIDs (like ibuprofen) can cause internal bleeding.
- Drug-food interactions: Some foods, like grapefruit, can interfere with how your body processes certain medications, making them either less effective or more potent than intended.
- Drug-herbal interactions: Herbal remedies, such as aloe vera or ginseng, may seem harmless, but when combined with prescription drugs, they can either lessen the medication’s impact or cause harmful side effects.
How do these drug interactions affect you?
Drug interactions can change the way medications work in your body.
- Reduced effectiveness of medications: The drugs may not work as well, meaning they won’t treat your condition properly. For instance, taking antacids with antibiotics can make the antibiotics less effective.
- Increased or unexpected side effects: You could experience stronger or new side effects than usual. Mixing alcohol with painkillers like ibuprofen may cause dizziness or stomach issues.
- Risk of overdose: Combining certain drugs can raise their levels in your body, leading to an accidental overdose. Combining sedatives and alcohol can dangerously slow down breathing, leading to overdose.
- Dangerous changes in blood pressure or heart rate: Some interactions can cause your heart rate to spike or drop. Some cold medicines can raise blood pressure, especially when mixed with heart medication.
- Organ damage: Long-term misuse may harm vital organs, especially the liver and kidneys. Long-term use of alcohol with paracetamol can harm the liver.
5 ways to avoid drug interactions
You can avoid bad reactions to drug interactions by doing the following things:?
- Always read labels: Before taking any medication, whether prescribed or over-the-counter, read the label to understand potential interactions. Pay attention to warnings about alcohol, food, or other medications.
- Avoid mixing medications without guidance: Never combine drugs, herbal treatments, or supplements without consulting a healthcare provider. Just because something is natural doesn’t mean it’s safe with prescription meds.
- Limit alcohol consumption: If you’re on medication, especially antibiotics, painkillers, or blood pressure meds, avoid alcohol entirely. Alcohol can worsen side effects or make drugs less effective.
- Be mindful of food: Certain foods can interfere with medication absorption. For example, dairy products can affect how antibiotics work. Stick to your doctor’s advice on when and what to eat.
- Consult your doctor or pharmacist: Always ask your healthcare provider or pharmacist about potential interactions when you’re prescribed new meds, especially if you’re already taking other drugs or herbal remedies.
In a country where self-medication is the norm, knowing how to avoid harmful drug interactions is essential for protecting your health. Make informed decisions, consult your healthcare providers, and be cautious of mixing meds with food, alcohol, or herbal treatments.
