Is the medicine suitable for me?
Before starting a medicine, you should check that the selected medicine is the right one for the purpose in question. This is particularly important when using over-the-counter medications.
- Is the medicine intended for the ailment in question?
- Is there something that prevents the use of the medicine, such as an allergy to a medicinal substance, other medication, or a chronic illness? Liver and kidney conditions, in particular, may prevent the use of certain medicines.
All medicines have factors that may prevent their use. You can be allergic to a medicinal substance or an excipient – for example, someone with a penicillin allergy cannot take penicillin (e.g. phenoxymethylpenicillin), or certain other antibiotics. Various chronic illnesses can also prevent the use of certain medicines. Liver and kidney conditions, in particular, must be taken into consideration when using several kinds of medicines because the medicines are excreted via the liver or the kidneys. Medicines you are already using may sometimes prevent the use of a new medicine because some medicines are not suitable for simultaneous use.
Pregnant and breast-feeding mothers are a special group with regard to the use of medicines. The primary rule is that you should avoid using medicines during pregnancy and breast-feeding. On the other hand, a relapse in an illness caused by the interruption of long-term medication may also pose a risk to the health of the mother or the child, so you must agree on medication during pregnancy and breast-feeding with your doctor. Special characteristics are also involved in the medication of children, and they must be taken into consideration before beginning to use the medicine. Facors preventing the use of a medicine can always be found on the package leaflet.
