1. Active ingredient composition and purpose of the drug

Whether you're using prescription drugs, over-the-counter products, sunscreens, or supplements, it's a good idea to read product labels to make sure they're used correctly to get the most out of the product. and may help prevent harmful side effects. You can find information about the active ingredient and purpose at the top of the label on over-the-counter medicines. This section will specify the effects of the drug on the label. For example, sunscreen will say should be used for sun protection, while ibuprofen tablets will tell us what kind of pain or symptoms it is used for. Therefore, you will know what the product on hand is used for.
Prescription drugs will not have a purpose printed on the box, as the doctor will decide their purpose for the specific medical situation. That doesn't mean they should be used for other purposes. You should only use prescription drugs for the purpose discussed with your doctor and never share them with others and strictly follow your doctor's orders.

2. Instructions for drug use

All medicines will have instructions for use on the packaging or printed instructions leaflet inside. You should read these even if you have used this medicine before because it may have changed.
The instructions that come with the product will tell you how often to take the medicine like "take it once daily" or "apply every two hours" and they can even tell you what time of day you should use them. This can make a difference in how well the medicine works, so it's important that you follow the instructions on the label closely.
The instructions will also tell you how and for how long to take the medicine. You can take some medications long-term, while others can only be used for a few days at a time. Long-term use of certain medications can harm the body or reduce their effectiveness.
Some medicines will require a whole pack eg a course of antibiotics prescribed by a doctor. But others will require prolonged use depending on symptoms such as pain relievers.
If you do not understand the instructions or you are not sure exactly how to take or use the medicine, ask your pharmacist or doctor for specific explanations.
The usage section will also give you quick information about the symptoms or diseases that the drug can treat. For example, a painkiller label might say it helps with toothaches, headaches, joint pain, and menstrual cramps.

3. Warnings on drug labels

Sometimes drugs can cause side effects, which means they affect the body in a way that is not their intended purpose. This may be due to the body reacting to the drug or to a substance reacting to the drug.
The warning section on the medicine box or on the leaflet will instruct us what to do if we experience side effects when using the product. Side effects can range from a rash to feeling nauseous and can be mild or severe.

The warnings will also list what you should not do when using or using the product. For example, some drugs can interact with alcohol. Therefore, you must not drink alcohol while taking it, and combining these drugs with alcohol can have moderate to severe and sometimes fatal consequences.
It is very important to read any warnings before using a medication, even for simple products like sunscreen. As this can help you identify side effects quickly and will use the drug safer.

4. Expiration date information section

Although we can end the treatment chain of a drug or a product before they have expired. However, keeping them until past due is not a good idea because their effects are lost and can cause unwanted side effects that can be dangerous. Storing multiple medications can also lead to confusion and also increase the risk of misuse.

The lot number and supplier's name will be used to identify the drug if there is a problem with the medication. Occasionally, drugs must be recalled if they may not be as safe as a packaging defect. You can tell if your drug has been recalled by checking the lot number and provider name printed on the label.
