Ever questioned why some medications stop working after being used for a few days? Those who have encountered this typically come to the conclusion that the medication is a fake, expired, or even a mistaken prescription.

Some will even go so far as to blame their village residents for being world-class athletes. But did you know that some meals and medications shouldn’t be combined?

Yes. We’ve compiled 6 foods that can stop your drugs from working or, even worse, result in harmful side effects. Share this to save a life because most people are probably unaware of it.

1. Banana and Anti-hypertensive drugs

Although bananas are a good source of potassium, anti-hypertensive medications raise blood potassium levels.

Bananas plus antihypertensive medications result in an excess of potassium, which can induce heart palpitations, irregular pulse, and disorders like arrhythmia. Embrace your heart.

2. Drugs to prevent malaria and vitamin C

The liver is where all medications are processed. Iron is necessary for the life cycle of malaria parasites, and the liver is rich in iron (plasmodium). Iron is absorbed by the liver with the aid of vitamin C.

As the liver has an excess of the iron they require to thrive, malaria parasites gather there and grow. This negates the effects of any anti-malarial medications you may be taking. So when you’re treating malaria, hold off on eating citrus fruits or taking vitamins.

3. Medications for pain and soft drinks

There is carbonated water in soft drinks. I mean, it’s written in big letters on the can or bottle label. Carbon dioxide gas with water produces carbonated water (LOL, no, you do not just add carbon dioxide and water together, it has to be dissolved under pressure and all). Since carbon dioxide and the acid it contains to enhance the concentration of medicines in the blood, taking painkillers and soft drinks together can result in toxicity that could be fatal.

4. Antibiotics and dairy products

Drugs called antibiotics are used to treat and prevent bacterial infections. Tetracycline and penicillin are two examples. Calcium-rich dairy products stop the body from absorbing these antibiotics. This lessens the drug’s effectiveness.

5. Statins and grapefruit

Statins are a class of medication used to decrease cholesterol levels, and like most medications, they have negative effects. A substance or molecule found in grapefruit prevents statins from being broken down in the intestine. It results in an elevated medication level, which increases the chance of negative effects.

6. Anti-Coagulants and Leafy Vegetables (Blood Thinner)

Blood coagulation is slowed down by drugs known as anticoagulants (Blood Thinners). No, they don’t really thin your blood; instead, they stop blood clots from getting bigger and are used to treat heart disease and avoid stroke. Aspirin and warfarin are two examples.

Leafy vegetables include a lot of vitamin K, which helps the blood coagulate. So what occurs? The drug’s effects are offset.
