I’m Worried About My Mental Health Medication, What Questions Can I Ask My GP or Pharmacist

You do not need detailed medical knowledge to ask good questions about medication.

If something worries you, the aim is not to work out the answer before the appointment. It is to describe the concern clearly enough for a qualified healthcare professional to help you understand it.

Your GP or prescribing clinician can review treatment in the context of your health and diagnosis. A pharmacist can explain medicines, instructions, interactions and many common medication questions.

If you do not understand why you are taking it

You can ask:

• What is this medicine intended to help with?• What changes would suggest it is helping?• When will the treatment be reviewed?• Is there anything about my health or other medication that is particularly relevant?

These are questions about understanding your treatment, not challenging the fact that it was prescribed.

If you are worried about side effects

Describe what you are experiencing rather than trying to identify the cause yourself.

Useful information can include when the problem started, whether it is constant or intermittent, how it affects everyday life and whether anything else changed around the same time.

You can ask whether the symptom could be related to your medicine and what professional advice applies in your circumstances.

Do not alter the prescription while waiting for an answer unless an appropriate healthcare professional tells you to do so.

If you are worried the medicine is not helping

Explain what has and has not changed.

You might ask how the clinician assesses whether the treatment is helping, whether the current timeframe is what they expected and when another review is needed.

Avoid turning general internet timelines into a decision that your medicine has failed.

If you are worried about dependence or withdrawal

Ask directly.

You can ask whether your medicine is associated with dependence or withdrawal symptoms, what you should do if you ever want to stop it and who would oversee that process.

NICE specifically recommends open, non-judgemental conversations about dependence and withdrawal for relevant medicines.

MH360 does not provide dose-reduction schedules or withdrawal instructions.

If you have missed a dose or taken medication differently

Tell the pharmacist, GP or prescriber exactly what happened.

Different medicines have different missed-dose and safety instructions, so avoid relying on a generic rule or somebody else’s prescription experience.

If you think you may have taken more medicine than prescribed, seek medicine-specific professional advice promptly.

If you take several medicines

Bring or provide an up-to-date list of prescription medicines, over-the-counter products and supplements.

You can ask whether there are interactions you should know about and whether one professional is overseeing the overall medication picture.

Do not stop one medicine because you are worried about an interaction without obtaining appropriate advice.

If you feel embarrassed about asking

Medication questions are a normal part of healthcare.

You are allowed to say that you did not understand an earlier explanation, forgot what you were told, read something that frightened you or are worried about taking the medicine.

A useful appointment should leave you clearer about what happens next and who to contact if another concern arises.

Know which professional may help

A pharmacist can be particularly helpful with how medicines are used, common side effects, interactions and information supplied with a prescription.

Your GP or prescribing clinician is the appropriate person for decisions requiring assessment of your diagnosis, treatment plan, monitoring or whether a prescription should change.

Specialist mental-health teams may also be involved where treatment is being managed in secondary care.

When the concern is urgent

If you think you may be experiencing a serious reaction to medication, seek urgent medical advice.

If you or somebody else is in immediate danger or there is a life-threatening emergency, call 999 or go to A&E.

If you are experiencing a mental health crisis and need urgent help but it is not a life-threatening emergency, contact NHS 111 and select the mental health option, or use your local NHS urgent mental health service.
