A '''therapy''' or '''medical treatment''' (often abbreviated '''tx''', '''Tx''', or '''T<sub>x</sub>''') is the attempted remediation of a [[health]] problem, usually following a [[medical diagnosis]].

As a rule, each therapy has [[indication (medicine)|indications]] and [[contraindication]]s. There are many different types of therapy. Not all therapies are [[Efficacy#Medicine|effective]]. Many therapies can produce unwanted [[adverse effect]]s.

''Medical treatment'' and ''therapy'' are generally considered synonyms. However, in the context of [[mental health]], the term ''therapy'' may refer specifically to [[psychotherapy]].

== History ==
{{Expand section|date=July 2021}}
Before the creating of therapy as a formal procedure, people told stories to one another to inform and assist about the world.<ref>{{cite web|url=https://www.talkspace.com/blog/psychotherapy-history-of-therapy/|title=A Brief History of Therapy|accessdate = 2 November 2022}}</ref> The term "healing through words" was used over 3,500 years ago in Greek and Egyptian writing.<ref>{{cite web|url=https://www.unk.com/blog/a-brief-history-of-psychotherapy/|title=A Brief History of Psychotherapy|accessdate = 2 November 2022}}</ref> The term [[psychotherapy]] was invented in the 19th century,<ref>{{cite journal|author= Shamdasani S. |year = 2005|title= Psychotherapy: The Invention of a Word|url=https://journals.sagepub.com/doi/10.1177/0952695105051123|accessdate = 2 November 2022}}</ref> and psychoanalysis was founded by [[Sigmund Freud]] under a decade later.

== Semantic field ==
The words '''''care''''', '''''therapy''''', '''''treatment''''', and '''''intervention''''' overlap in a [[semantic field]], and thus they can be [[synonym]]ous depending on [[context (language use)|context]]. Moving rightward through that order, the [[connotation|connotative]] level of [[holism]] decreases and the level of specificity (to [[wikt:concrete#Adjective|concrete]] instances) increases. Thus, in [[health care]] contexts (where its [[word sense|senses]] are always [[mass noun|noncount]]), the word ''care'' tends to imply a broad idea of everything done to protect or improve someone's health (for example, as in the terms ''[[preventive healthcare|preventive care]]'' and ''[[primary care]]'', which connote ongoing action), although it sometimes implies a narrower idea (for example, in the simplest cases of [[wound care]] or [[post-anesthesia care unit|postanesthesia care]], a few particular steps are sufficient, and the patient's interaction with that provider is soon finished). In contrast, the word ''intervention'' tends to be specific and concrete, and thus the word is often [[count noun|countable]]; for example, one instance of [[cardiac catheterization]] is one [[Medical procedure|intervention]] performed, and [[coronary care unit|coronary care]] (noncount) can require a series of interventions (count). At the extreme, the piling on of such countable interventions amounts to [[interventionism (medicine)|interventionism]], a flawed model of care lacking holistic [[wikt:circumspection#Noun|circumspection]]—merely treating [[wikt:discrete#Adjective|discrete]] problems (in billable increments) rather than maintaining health. ''Therapy'' and ''treatment'', in the middle of the semantic field, can connote either the holism of ''care'' or the discreteness of ''intervention'', with context conveying the intent in each use. Accordingly, they can be used in both noncount and count senses (for example, ''therapy for [[chronic kidney disease]] can involve several [[Kidney dialysis|dialysis]] treatments per week'').

The words ''aceology'' and ''iamatology'' are obscure and obsolete synonyms referring to the study of therapies.

The English word ''therapy'' comes via Latin ''therapīa'' from {{lang-grc-gre|θεραπεία}} and literally means "curing" or "healing".<ref>[http://www.etymonline.com/index.php?allowed_in_frame=0&search=therapy&searchmode=none Online Etymology Dictionary, ''Therapy'']</ref>

=== By chronology, priority, or intensity ===
==== Levels of care ====
Levels of care classify [[health care]] into categories of chronology, priority, or intensity, as follows:
* [[Emergency medicine|Emergency care]] handles [[medical emergency|medical emergencies]] and is a first point of contact or intake for less serious problems, which can be referred to other levels of care as appropriate.
* [[Intensive care medicine|Intensive care]], also called [[Critical care medicine|critical care]], is care for extremely ill or injured patients. It thus requires high resource intensity, knowledge, and skill, as well as quick [[decision making]].
* [[Ambulatory care]] is care provided on an [[patient#Outpatients and inpatients|outpatient]] basis. Typically patients can walk into and out of the clinic under their own power (hence "ambulatory"), usually on the same day.
* [[Home care]] is care at home, including care from providers (such as physicians, nurses, and home health aides) making [[house call]]s, care from [[caregiver]]s such as family members, and patient [[self care|self-care]].
* [[Primary care]] is meant to be the main kind of care in general, and ideally a [[medical home]] that unifies care across referred providers.
* [[Secondary care]] is care provided by medical specialists and other health professionals who generally do not have first contact with patients, for example, [[cardiologists]], [[urologists]] and [[dermatologists]]. A patient reaches secondary care as a next step from [[primary care]], typically by provider referral although sometimes by patient self-initiative.
* [[Tertiary care]] is specialized consultative care, usually for [[patient#Outpatients and inpatients|inpatients]] and on referral from a primary or secondary health professional, in a facility that has personnel and facilities for advanced medical investigation and treatment, such as a [[tertiary referral hospital]].
* Follow-up care is additional care during or after [[convalescence]]. Aftercare is generally synonymous with follow-up care.
* [[End-of-life care]] is care near the end of one's life. It often includes the following:
** [[Palliative care]] is [[#Supportive therapy|supportive care]], most especially (but not necessarily) near the end of life.
** [[Hospice]] care is palliative care very near the end of life when [[cure]] is very unlikely. Its main goal is comfort, both physical and mental.

==== Lines of therapy ====

Treatment decisions often follow formal or informal [[algorithm]]ic guidelines. Treatment options can often be ranked or prioritized into '''lines of therapy''': '''first-line therapy''', '''second-line therapy''', '''third-line therapy''', and so on. '''First-line therapy''' (sometimes referred to as '''induction therapy''', '''primary therapy''', or '''front-line therapy''')<ref>[http://www.cancer.gov/dictionary/?CdrID=346494 National Cancer Institute > Dictionary of Cancer Terms > first-line therapy] Retrieved July 2010</ref> is the first therapy that will be tried. Its priority over other options is usually either: (1) formally recommended on the basis of [[clinical trial]] evidence for its best-available combination of efficacy, safety, and tolerability or (2) chosen based on the clinical experience of the physician. If a first-line therapy either fails to resolve the issue or produces intolerable [[side effect]]s, additional (second-line) therapies may be substituted or added to the treatment regimen, followed by third-line therapies, and so on.

An example of a context in which the formalization of treatment algorithms and the ranking of lines of therapy is very extensive is [[chemotherapy regimens]]. Because of the great difficulty in successfully treating some forms of cancer, one line after another may be tried. In [[oncology]] the count of therapy lines may reach 10 or even 20.

Often multiple therapies may be tried simultaneously ([[combination therapy]] or polytherapy). Thus [[combination chemotherapy]] is also called polychemotherapy, whereas chemotherapy with one agent at a time is called single-agent therapy or monotherapy.

[[Adjuvant therapy]] is therapy given in addition to the primary, main, or initial treatment, but simultaneously (as opposed to second-line therapy). [[Neoadjuvant therapy]] is therapy that is begun before the main therapy. Thus one can consider surgical excision of a tumor as the first-line therapy for a certain type and stage of cancer even though radiotherapy is used before it; the radiotherapy is neoadjuvant (chronologically first but not primary in the sense of the main event). [[Premedication]] is conceptually not far from this, but the words are not interchangeable; cytotoxic drugs to put a tumor "on the ropes" before surgery delivers the "knockout punch" are called neoadjuvant chemotherapy, not premedication, whereas things like anesthetics or prophylactic antibiotics before dental surgery are called premedication.

[[Step therapy]] or stepladder therapy is a specific type of prioritization by lines of therapy. It is controversial in [[health care in the United States|American health care]] because unlike conventional [[decision-making]] about what constitutes first-line, second-line, and third-line therapy, which in the U.S. reflects safety and efficacy first and cost only according to the patient's wishes, step therapy attempts to mix cost containment by someone other than the patient (third-party payers) into the algorithm. [[Therapy freedom]] and the negotiation between [[individual and group rights]] are involved.

|- valign="top"
! scope="row" | {{Anchor|Abortive therapy}} abortive therapy
| A therapy that is intended to stop a medical condition from progressing any further. A medication taken at the earliest signs of a disease, such as an [[analgesic]] taken at the very first symptoms of a [[migraine headache]] to prevent it from getting worse, is an abortive therapy. Compare [[abortifacient]]s, which abort a pregnancy.
|- valign="top"
! scope="row" | {{Anchor|Bridge therapy}} [[bridge therapy]]
| A therapy that [[figurative analogy|figuratively]] provides a bridge to another step or phase, crossing over some immediate chasm (challenge), in contrast with [[destination therapy]], which is the final therapy in cases where clinically appropriate.
|- valign="top"
! scope="row" | {{Anchor|Consolidation therapy}} consolidation therapy
| A therapy given to consolidate the gains from [[#Lines of therapy|induction therapy]]. In cancer, this means chasing after any malignant cells that may be left.
|- valign="top"
! scope="row" | {{Anchor|Curative therapy}} curative therapy
| A therapy with ''curative intent'', that is, one that seeks to [[cure]] the root cause of a disorder. (also called etiotropic therapy)
|- valign="top"
! scope="row" | {{Anchor|Definitive therapy}} definitive therapy
| A therapy that may be final, superior to others, [[#Curative therapy|curative]], or all of those.
|- valign="top"
! scope="row" | {{Anchor|Destination therapy}} [[destination therapy]]
| A therapy that is the final destination rather than a [[bridge therapy|bridge]] to another therapy. Usually refers to [[ventricular assist device]]s to keep the existing heart going, not just until [[heart transplantation]] can occur, but for the rest of the patient's life expectancy.
|- valign="top"
! scope="row" | {{Anchor|Empiric therapy}} [[empiric therapy]]
| A therapy given on an empiric basis; that is, one given according to a clinician's educated guess despite uncertainty about the illness's causative factors. For example, empiric antibiotic therapy administers a [[broad-spectrum antibiotic]] immediately on the basis of a good chance (given the history, physical examination findings, and risk factors present) that the illness is bacterial and will respond to that drug (even though the bacterial species or variant is not yet known).
|- valign="top"
! scope="row" | {{Anchor|Gold standard therapy}} gold standard therapy
| A therapy that is [[#Definitive therapy|definitive]], just as a [[gold standard (test)|gold standard diagnostic test]] is a definitive test.
|- valign="top"
! scope="row" | {{Anchor|Investigational therapy}} investigational therapy
| An [[experiment]]al therapy. Use of experimental therapies must be ethically justified, because by definition they raise the question of [[standard of care]]. Physicians have autonomy to provide empirical care (such as [[off-label use|off-label]] care) according to their experience and clinical judgment, but the autonomy has limits that preclude [[quackery]]. Thus it may be necessary to design a [[clinical trial]] around the new therapy and to use the therapy only per a formal [[protocol (science)|protocol]]. Sometimes shorthand phrases such as "treated on protocol" imply not just "treated according to a plan" but specifically "treated with investigational therapy".
|- valign="top"

|- valign="top"
! scope="row" | {{Anchor|Preventive therapy}} preventive therapy<br />{{nowrap|(prophylactic therapy)}}
| A therapy that is intended to [[preventive healthcare|prevent a medical condition]] from occurring (also called prophylaxis). For example, many [[vaccine]]s prevent infectious diseases.
|- valign="top"
! scope="row" | {{Anchor|Salvage therapy}} [[salvage therapy]] (rescue therapy)
| A therapy tried after others have failed; it may be a "last-[[#Lines of therapy|line]]" therapy.
|- valign="top"
! scope="row" | {{Anchor|Stepdown therapy}} stepdown therapy
| Therapy that tapers the dosage gradually rather than abruptly cutting it off. For example, a switch from intravenous to oral antibiotics as an infection is brought under control steps down the intensity of therapy.
|- valign="top"
! scope="row" | {{Anchor|Supportive therapy}} supportive therapy
| A therapy that does not treat or improve the underlying condition, but rather increases the patient's comfort, also called [[symptomatic treatment]] (see there for more information).<ref>{{cite web |url=http://www.cfids.org/about-cfids/supportive-therapy.asp |title=CFIDS |publisher=CFIDS |access-date=2012-01-09 |url-status=dead |archive-url=https://web.archive.org/web/20120213075456/http://www.cfids.org/about-cfids/supportive-therapy.asp |archive-date=2012-02-13 }}</ref> For example, supportive care for flu, colds, or gastrointestinal upset can include rest, fluids, and [[over-the-counter drug|over the counter]] pain relievers; those things don't treat the cause, but they treat the symptoms and thus provide relief. Supportive therapy may be palliative therapy ([[palliative care]]). The two terms are sometimes synonymous, but palliative care often specifically refers to serious illness and [[end-of-life care]]. Therapy may be categorized as having [[#Curative therapy|curative intent]] (when it is possible to eliminate the disease) or ''palliative intent'' (when eliminating the disease is impossible and the focus shifts to minimizing the distress that it causes). The two are often [[wikt:contradistinguish#Verb|contradistinguished]] (mutually exclusive) in some contexts (such as the [[management of cancer|management of some cancers]]), but they are not inherently mutually exclusive; often therapy can be both curative and palliative simultaneously. [[Supportive psychotherapy]] aims to support the patient by alleviating the worst of the symptoms, with the expectation that [[#Definitive therapy|definitive therapy]] can follow later if possible.
|- valign="top"
! scope="row" | {{Anchor|Systemic therapy}} systemic therapy
| A therapy that is [[wikt:systemic#Adjective|systemic]]. In the physiological [[word sense|sense]], this means affecting the whole body (rather than being local or locoregional), whether via [[systemic administration]], systemic effect, or both. [[Systemic therapy (psychotherapy)|Systemic therapy in the psychotherapeutic sense]] seeks to address people not only on the individual level but also as people in relationships, dealing with the interactions of groups.
