Why a Medicine May Be Reduced or Stopped

A medicine can be right when it starts and still need review later. Reducing or stopping treatment is not automatically safer than continuing it. The decision should be shared, medicine specific and supported by monitoring.

Reviewing a medicine is part of good care A medicine can be appropriate when it starts and still need review later. Health conditions, evidence, goals and other treatments can change over time. A medication review checks whether each medicine is still needed, effective, safe and acceptable. The result may be to continue, adjust, switch or stop it. Deprescribing is the planned and supervised reduction or stopping of a medicine that may be causing harm or no longer providing enough benefit. It is not simply an attempt to reduce prescription numbers. The purpose is to improve care while protecting benefits that still matter. This lesson uses a practical five question teaching framework. It is not a universal deprescribing checklist and does not replace medicine specific guidance. Five questions shape the review First, what is the indication for the medicine? An indication is the health problem or preventive aim that explains why it is being used. Second, what benefit is it providing now or expected to provide later? Some preventive medicines have no noticeable daily effect but reduce future risk. Third, what harms or burdens could continuing create? These can include an adverse effect, an interaction, monitoring demands, treatment complexity or difficulty taking the medicine. Fourth, what matters to the person? Their priorities, previous experiences, support, ability to manage the treatment and willingness to change all matter. Fifth, how could the medicine be changed safely? The plan needs the right method, review timing, responsible clinician and action thresholds. Polypharmacy can be appropriate Polypharmacy means using several medicines. It can be appropriate when each medicine has a clear purpose and the overall combination provides worthwhile benefit. Problematic polypharmacy occurs when the total treatment no longer fits the person's needs. Examples include unclear indications, duplication, unacceptable burden or harms outweighing likely benefits. The number of medicines alone does not decide whether treatment is appropriate. One poorly chosen medicine can cause harm, while several well chosen medicines may be necessary. Interactions also vary. Some combinations are deliberately used, while others change medicine effects or increase risk and require adjustment or monitoring. Why a medicine may be reduced or stopped The original indication may have resolved, or the medicine may not have achieved its intended outcome. Another treatment may now offer a better balance. An adverse effect can become more important after a new illness, reduced kidney or liver function, frailty or another medicine is added. The expected time to benefit may no longer fit the person's circumstances or priorities. This is especially relevant for some preventive medicines. The person may also prefer fewer tablets, simpler dosing or a different treatment after discussing the likely consequences. None of these reasons makes stopping automatic. The review must consider what could be lost as well as what harm might be avoided. Why continuing may be the right decision A medicine may still control symptoms, prevent relapse or reduce the risk of a serious complication. Stopping could cause more harm than continuing. A medication review can therefore conclude that the current treatment should continue unchanged. Reviewing a medicine does not mean the clinician has already decided to stop it. Some long term treatments remain essential even when the person feels well. The absence of symptoms may show that the medicine is working rather than no longer needed. The decision should also account for the person's preferences. However, preferences need accurate information about expected benefits, risks and alternatives. Stopping methods differ between medicines Some medicines can be stopped directly. Others need a gradual dose reduction, sometimes called tapering, because sudden stopping can cause withdrawal or dangerous worsening. The correct method depends on the medicine, dose, duration, reason for use and individual response. There is no single schedule that is safe for every medicine. Serious or intolerable harm can sometimes require a faster change. The prescriber still considers the medicine's specific risks and arranges suitable support. Do not reduce, skip or stop a prescribed medicine independently. Check with the prescriber or pharmacist responsible for the treatment. Withdrawal, rebound and relapse are different A withdrawal symptom results from the body adapting to a medicine and then responding to a dose reduction or stopping. A rebound effect is a temporary return of symptoms that can be stronger than before treatment. It is linked to removing the medicine's effect. A relapse is the return of the underlying condition after improvement or remission. It may require renewed or different treatment. These patterns can overlap and may be difficult to distinguish. Timing, symptom type, previous illness and response to dose changes all provide clues. New symptoms during reduction should not be dismissed as expected withdrawal. The plan should explain who to contact and whether the next reduction should pause. What a safe plan contains The plan records which medicine is changing, why it is changing and whether it will stop directly or reduce in stages. It states what will be monitored, when review occurs and who is responsible. Monitoring can include symptoms, function, blood pressure, blood tests or other medicine specific measures. It also explains what would prompt a slower reduction, a pause, a return to the previous dose or another treatment discussion. Management of the original condition should continue when needed. Removing one medicine should not leave an important health problem without a plan. When several non urgent changes are possible, clinicians may separate them so each effect is easier to interpret. Urgent safety needs can require a different approach. An antidepressant example Antidepressants can prevent relapse for some people who have recovered from depression. Continuing treatment may be particularly valuable when relapse risk remains high. NICE recommends reviewing antidepressant treatment used for relapse prevention at least every six months. The review includes mood, adverse effects, circumstances and whether the person wishes to continue. When stopping is agreed, antidepressants usually need staged dose reductions. The schedule should reflect the medicine, treatment duration, previous withdrawal and the person's response. Withdrawal symptoms can include dizziness, altered sensations, anxiety, low mood, sleep problems and nausea. They vary greatly between people. The clinician also monitors for relapse of depression. A rapid unfamiliar symptom after a dose reduction may suggest withdrawal, but the full pattern still needs assessment. Taking part in the decision Ask why the medicine was started and whether that indication still applies. Ask what benefit continuing is expected to provide. Ask about adverse effects, interactions, alternatives and what could happen after a dose change. Confirm whether the medicine needs tapering. Ask who will review the plan, when review will occur and what symptoms require earlier contact. Request written instructions when several dose changes are involved. Call 999 or go to A&E if someone is in immediate danger, has seriously harmed themselves or has taken an overdose. In England, call 111 and select the mental health option for urgent help that is not an emergency. Follow the urgent mental health route for the UK nation where you are. Seek prompt clinical advice if mood worsens or suicidal thoughts appear during an antidepressant reduction. This lesson explains professional medication review and deprescribing. It cannot tell you whether your medicine should be changed or stopped.

Deprescribing is not simply using fewer medicines. It is a person centred decision about whether each treatment remains needed, effective, safe and worthwhile. Some medicines can stop directly, while others require a flexible taper and close review.
