Having a family history of a drug allergy may increase the risk of one developing an allergy after taking the same drug. However, do note there are other factors that play a role in allergies, such as the presence of other allergies, history of medical conditions such as asthma, as well as environmental factors. Hence, having a family member with a drug allergy does not mean one will definitely have the same allergy.

Most drug allergies are only discovered when an individual consumed the drug and developed an allergy. Alternatively, you may wish to discuss with a doctor regarding the use of skin prick tests to determine whether you have an allergy. Do note that skin prick tests may not always be accurate. It may indicate an allergy that you do not have, or may not trigger a reaction when you are exposed to something that you are allergic to.

The expiry date of the medicine can be found on the medicine packaging or label. It may say:

• expiry
• expiry date
• exp
• use by

Most medicines can be taken safely until the expiry date. However, do note that some medicines may have a limited shelf-life after opening. You may wish to check the packaging or labels for more information. Alternatively, you may wish to see a pharmacist and request for his/her help to help to determine the shelf-lives of your medicines.

Medicines may lose their effectiveness and safety over time. The expiry date is the last day that the manufacturer guarantees the full safety and effectiveness of the medicine. Hence, it is not advisable to consume medicines after their expiry date.

Heat and moisture may damage medicines. Improper storage places, such as damp bathroom cabinets, may reduce the effectiveness of medicines before their expiry dates. Always ensure that medicines are stored away from sunlight, at a cool, dry place such as the bedroom drawers.

In summary, always store your medicines properly and throw away any expired products. 

Grapefruits contain a type of chemical called furanocoumarins which reduces the clearing of certain medicines, such as simvastatin, from the body. This may in turn lead to more side effects. One glass of grapefruit juice was reported to increase simvastatin level in the body by 2 to 3 fold. Hence, grapefruits should be avoided in people taking simvastatin.

Certain citrus fruits such as Seville oranges and pomelos also contain furanocoumarins. However, there is a lack of studies done on these fruits to determine the magnitude of their effects on simvastatin. Hence, you may wish to avoid pomelo if you are concerned about the possibility of increased side effects.
