Contraindications are super important for using medications safely and effectively.

These are specific situations where a medication shouldn't be used because it might cause harm or make a person's health worse.

It's really important for healthcare providers to know about these contraindications so they can avoid any bad reactions.

Let’s look at aspirin as an example. People often use it to relieve pain and reduce inflammation.

But, it shouldn’t be given to someone who has active peptic ulcer disease, as it could make them bleed more.

Another example is beta-blockers. These are common medicines for high blood pressure, but they should not be used by patients with asthma because they can cause breathing problems.

Here are some more examples:

Common Medications and Their Contraindications
