Admittedly, they are a bit annoying, these small, thin leaflets in the drug package, but it is still advisable to take a closer look. Because the leaflet contains important information that you should pay attention to before and when you take it.


At this point, drugs are listed by their type and amount. Other ingredients such as flavor enhancers, ointment bases, dyes and fillers must be listed by the manufacturer, but should not be quantified.

Instruction of dosage and kind of usage

This is not only about the amount of the dose to be taken, the frequency of ingestion, but also about the duration of an application. Some medications are only taken as needed (eg painkillers) while others are consumed throughout (eg antibiotics).

Time of application

Often there is an additional indication of when they should ideally be taken. Some people only fully develop their effects when taken with some liquid or with meals. It is therefore very important to read the package leaflet carefully, otherwise the effect of the medication may be impaired. What do the times of the application instructions mean?

  • Before eating: about half an hour before eating.
  • To eat: about the middle of the meal.
  • Immediately after eating: within 30 minutes after eating.
  • After the meal: two hours after the meal.
  • Once a day: every day at the same time. The best time can be found in the leaflet. If there is nothing, the time of taking it does not matter.
  • Twice a day: every twelve hours.
  • Three times a day: every eight hours.


This refers to diseases and other circumstances under which the drug may not be used. So z. As pregnancy, lactation, chronic underlying diseases or immunodeficiency contraindications for certain drugs.


A medicine can affect, partially cancel, or increase the potency and duration of other preparations. Drugs that require special care include blood thinners, antidepressants, oral contraceptives (pill), analgesics, some antibiotics, antiepileptic drugs or antidiabetics. In order to avoid possible interactions, it is advisable to tell the doctor during a visit to the doctor (especially during the first visit) which medications you are currently or currently taking.

In case of uncertainties, the pharmacy can also provide information about the so-called interactions. Incidentally, even food can interact with a drug such. As coffee, grapefruit juice, milk, liquorice and not to forget alcohol.

side effects

All unwanted effects of the product are listed here - if known. However, this does not necessarily mean that side effects have to occur - none of which you will "inevitably"! The legal requirements oblige the manufacturer, however, to identify all side effects that have occurred. What actually mean the frequency information in the side effects?

  • Very common = more than 10%
  • common = less than 10%, more than 1%
  • occasionally = 0.1 - 1%
  • rare = less than 0.1%, more than 0.01%
  • very rare = less than 0, 01%
  • Individual cases = individual cases, not yet evaluable

A side effect is therefore a normally unwanted effect of a drug, a so-called undesirable drug effect. The spectrum is very wide, ranging from mild nausea to life-threatening reactions such. Anaphylactic shock. Side effects are not only caused by the active ingredient, but also by the user himself. For example, incorrect dosage, ingestion errors or non-observance of possible interactions are possible causes of side effects.


If you have any uncertainties about individual items on the leaflet, talk to your doctor or pharmacist. The more information you have, the more targeted and safer you can use your medication.
