Patients may comply less well with their prescribed antidepressant regimens than they do with treatments for their physical disorders.¹
What follows is an algorithm for addressing a variety of non-pharmacologic barriers to good response in the acute pharmacologic treatment of depression. Recognition and management of non-compliance is one factor which receives extended consideration. Non-compliance is also an issue in maintenance treatment and this section may be helpful for that, as well. Other causes of frequent relapse are addressed in a separate "Place to Go" entitled "Frequent relapses..."

uestion:
Is the patient taking the medication as prescribed?
Help: Suspect non-compliance or partial compliance if any of the following apply:
uestion:
Has sufficient time been spent with the patient to assess subjective
response to the medication, and address concerns about side effects?
Comment: The education process must be ongoing and ideally should involve the family.¹ Use of a multidisciplinary team approach results in the best compliance, with oral and written information given by nurses, pharmacists, and psychotherapists supplementing and reinforcing the information provided by the physician.² When the prescriber is a primary care physician working in a general medical practice, the above is much less likely to occur.³ Physicians may spend even less time with patients who are in pre-paid insurance plans vs. fee-for-service plans.³

uestion:
What is the patient's understanding of the causes of their depressive
illness?
Comment: Lack of insight is very common and has been established as a factor in treatment non-compliance in patients with schizophrenia.¹ Although it has received less attention in depression, the patient's "explanatory model" of the illness is probably a significant factor in non-compliance with treatment.² The clinician should elicit the patient's self-formulation and look for irrational beliefs.

Sufficient time should be spent to define the illness, describe target symptoms for medication, suggest expected time course of response, review side effects of medication, sequence of doses and what to do if problems arise, and encourage the patient to ask questions. Patients should be given a patient information sheet about the medication to take with them. Review all the side effects listed on the sheet during the session and refer back to it in subsequent meetings if necessary. An appointment in one week is recommended after starting antidepressant medication, to check for possible deterioration, early side effects, or other reasons for early non-compliance.¹
Sexual side effects seem to be underemphasized by clinicians. They occur in as high as 75% of patients taking SSRI antidepressants² such as fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil), and have been described as the "Achilles Heel" of these medications. Patients are often not clearly informed about them, and even if they are informed, they may be reluctant to bring them up with their physician. They must contribute to non-compliance more than has been generally appreciated.

The patient may need more counseling and negotiation to resolve the differing formulations of the problem. The clinician should offer a more comprehensive model of the factors (biological and psychosocial) that are contributing to the depression and how different treatments address the different factors. This should be tailored to the patients experience by incorporating some aspect of the patient's explanation if possible. For example, if the patient believes that insomnia is the cause of everything, the patient should be told that inability to sleep is, in fact, an important symptom of the depression syndrome, and improvement in sleep would be a good indicator of when the depression is starting to improve. Then, sleep would be monitored closely.¹

uestion:
Does the patient have a complicated medication treatment regimen that
could be simplified?
Comment: Even if the patient is only on one, relatively uncomplicated pharmacotherapeutic agent, he/she may be on other non-psychiatric medications which make the overall task of keeping them organized rather difficult. This is especially common in the elderly, where non-compliance rates have been reported to be as high as 75%.¹ Patients with organicity, attention-deficit disorder, or long and demanding work schedules often forget or confuse their medication schedules. Actually, it is probably the exceptional patient who is compulsively reliable with oral medication compliance.

To help patients with complicated medication regimens, the following might be tried:
uestion:
Does the patient have significant others who are not supportive of the
pharmacotherapy? (e.g. - spouse, parents, AA sponsor)
Comment: "Not supportive" could mean overt opposition ("There's nothing wrong with you, you don't need that crutch.") However, it could also mean excessive (albeit well-motivated) reminders ("nagging") that stimulates oppositional behavior. Sometimes pill-pushing by significant others is motivated in part by their own resistance to accepting any responsibility for contributing to the stress in the patient's life that is fueling the depression. The patient may feel that taking the medication is equivalent to admitting that the problem is all theirs and that the significant other does not need to change in any way.
Consider having a family compliance counseling session.¹ Explore what the significant other's understanding of the illness is, and what they think the patient's needs are. Psychoeducational work may be helpful.² Sometimes, more complicated and multidetermined undermining of the treatment plan may be going on, which may require a series of meetings to address.

uestion:
Does the patient have certain personality traits that might call for a
particular individualized approach to improving compliance? [This is the
last question in the compliance algorithm]
Comment: A paper by Ward was the source of the suggestions found in the links to the three trait categories listed.¹

For dependent patients: These patients are generally compliant but if they are not, they may hide this fact so as to not displease the clinician, family members, or significant others. Supportively explore possible reasons for non-compliance: explanatory model, cost, side effects, etc.
For the compulsive/paranoid patient: These patients require more extensive discussion and reassurance than others. They particularly appreciate being offered different treatment choices or alternatives so they can actively make choices and feel in control. Allow more options and go over contingencies in advance when presenting the titration schedule.
Passive-aggressive/hostile-dependent patients: These patients are particularly prone to poor compliance. They require detailed explanations of the medication, indications, target symptoms, side effects, etc., and yet they may still refuse to try it on a minor point. The best approach is to be very clear about the limitations of drug therapy. Avoid excessive claims for benefits and undue reassurance about side effects. These patients report more side effects than other patients, and this should be responded to with sober professionalism. Sometimes a "counterprojective approach" of slightly exaggerating the problems with medication and anticipating their negative appraisal of the medication may allow them to feel more comfortable with going ahead with an adequate trial.
