Check Drug Interactions: General Medicine Compatibility Info

All You Need To Know About Drug Interactions

You may notice that sometimes people on certain medications do not show any improvement. Instead, their condition worsens with time. They may develop a feeling of resentment against doctors or pharmaceutical authorities, believing they have failed to provide proper medication. 


In cases like this, there is a strong possibility that unforeseen drug interactions are at play. Although medications help us feel better and stay healthy, sometimes drug interactions can cause problems.

What Are Drug Interactions?

Interactions between prescription medication and over-the-counter (OTC) medications are very common. Drug interactions take place due to the combined reaction of medicine with another parallel intake. It can either be food, beverages, or any other medicine. 


Multiple drugs can amplify side effects and lead to situations where medication is non-effective. Some of these reactions can cause serious health issues. To protect yourself, it is extremely important to discuss with a doctor your health condition(s), possible interactions, and food allergies before starting any medication. 


Also, you can familiarize yourself with general drug compatibility best practices and utilize widely available drug interaction charts

Types Of Drug Interactions

Some of the most common types of drug interactions include:

Drug-Drug Interaction

This is one of the most common kinds of interactions that people experience. When multiple drugs are taken for different treatments, they decrease the impact of one another and mutually uplift the impact of adverse reactions. 


Cross-functional drugs can even nullify the actual benefit of medication, prolonging diseases and sickness. 

Drug-Food/Beverage Interaction

When a drug is consumed with certain foods or beverages, it can lower or worsen the impact of medication. For example, cholesterol patients are recommended to avoid grapefruit juice while they are on a medication regimen. 


The process behind this specific interaction has to do with statin medication (used to fight cholesterol) combining  with grapefruit juice. This causes skeletal muscle tissue to decompose and release harmful enzymes. There can be incredibly damaging negative effects on the liver and kidneys.

This is just one example that illustrates why it is so important to avoid any food or drink intake that counteracts medication you may be consuming. 

Drug-Disease Interaction

This kind of interaction generally arises when a patient does not fully cooperate and does not share a complete list of medical conditions with their doctor. Sometimes doctors recommend medication, but as soon as the process begins, the patient feels even worse. This usually happens when a prescription creates another complication inside the body. 


For example, a diabetic patient might be recommended Metformin medication which can adversely impact their kidneys. If they do not inform their doctor that they have pre-existing kidney issues or medication, there could be dire consequences.

Most people who do not take their multiple health issues seriously encounter this type of drug interaction. 

Common Drug Interactions And How To Avoid Them

Some common drug interactions and their solutions include:

OTC Interactions

All kinds of prescription and non-prescription medications come with a list of important information including ingredients, warnings, usage/dosage recommendations, and possible drug interactions. It’s important to pay special attention to any details outlined regarding adverse reactions due to interactions with other drugs, food, or alcohol. Multiple OTC medications can share common active ingredients. You need to cross-check all such tiny details or use a drug interaction checker to make the job easier.

Drug Interactions And Food Allergies

When your doctor puts you on any medication, discuss all the details about that drug, its usage, and the recommended food intake for your regimen. If you are already on other medications or herbal supplements, inform your doctor about them. 


Prepare a list of questions before accepting a prescription. You can also make a proper timetable and a diet plan. By preparing in advance to be mindful regarding medicine interactions, you can be aware of compatible and incompatible foods/beverages while taking OTC drugs.
