Self-medication

Self-medication is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Self-medication rather than just read about it. In short: Self-medication, sometimes called do-it-yourself (DIY) medicine, is a human behavior in which an individual uses a substance or any exogenous influence to self-administer treatment for physical or psychological conditions, for example headaches or fatigue. The substances most widely used in self-medication are over-the-counter drugs and dietary supplements, which are used to treat common health issues at home.

Key takeaways

  • Self-medication belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Self-medication to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Self-medication from memory before moving on to harder problems.

Reference excerpt

Self-medication, sometimes called do-it-yourself (DIY) medicine, is a human behavior in which an individual uses a substance or any exogenous influence to self-administer treatment for physical or psychological conditions, for example headaches or fatigue. The substances most widely used in self-medication are over-the-counter drugs and dietary supplements, which are used to treat common health issues at home. These do not require a doctor's prescription to obtain and, in some countries, are available in supermarkets and convenience stores. The field of psychology surrounding the use of psychoactive drugs is often specifically in relation to the use of recreational drugs, alcohol, comfort food, and other forms of behavior to alleviate symptoms of mental distress, stress and anxiety, including mental illnesses or psychological trauma. Such treatment may cause serious detriment to physical and mental health if motivated by addictive mechanisms. In postsecondary (university and college) students, self-medication with "study drugs" such as Adderall, Ritalin, and Concerta has been widely reported and discussed in literature. Products are marketed by manufacturers as useful for self-medication, sometimes on the basis of questionable evidence. Claims that nicotine has medicinal value have been used to market cigarettes as self-administered medicines. These claims have been criticized as inaccurate by independent researchers. Unverified and unregulated third-party health claims are used to market dietary supplements. Self-medication is often seen as gaining personal independence from established medicine, and it can be seen as a human right, implicit in, or closely related to the right to refuse professional medical treatment. Self-medication can cause unintentional self-harm. Self-medication with antibiotics has been identified as one of the primary reasons for the evolution of antimicrobial resistance. Sometimes self-medication or DIY medicine occurs because patients disagree with a doctor's interpretation of their condition, to access experimental therapies that are not available to the public, or because of legal bans on healthcare, as in the case of some transgender people or women seeking self-induced abortion. Other reasons for relying on DIY medical care is to avoid health care prices in the United States and anarchist beliefs.

Definition Generally speaking, self-medication is defined as "the use of drugs to treat self-diagnosed disorders or symptoms, or the intermittent or continued use of a prescribed drug for chronic or recurrent disease or symptoms". Self-medication can be defined as the use of drugs to treat an illness or symptom when the user is not a medically qualified professional. The term is also used to include the use of drugs outside their license or off-label.

Worked examples

Example 1 — a first encounter with Self-medication

Start with the simplest possible case. Write down what Self-medication claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Self-medication before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Self-medication ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Self-medication

In research
Self-medication appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Self-medication in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Self-medication is common in secondary-school and first-year university syllabi. It links to neighbouring topics Addiction, Alcohol and health, Anxiety, so understanding it makes those chapters shorter.
In everyday life
Look for Self-medication outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Self-medication matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Self-medication?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
