What to do if you think you’ve been given the wrong dose of a medication

Advice for people living with aspergillosis

Most of the time, prescriptions are correct and safe. However, people with aspergillosis often have complex medical needs, and it is not unusual for treatment to differ from standard “one-size-fits-all” dosing. This means that occasionally, a prescription may not match what you usually receive or what your specialist has recommended.

If something doesn’t look right, it is reasonable — and responsible — to pause and check.

Why this can happen

Prescribing in GP surgeries and hospitals is usually done using electronic systems with preset doses and durations. These defaults are designed for the average patient and for common infections.

People with aspergillosis may:

• need longer or higher-dose treatment

• be taking interacting medicines (for example antifungals or steroids)

• have been advised by a specialist to follow a non-standard plan

If this information is not clearly visible at the time of prescribing, the prescriber may reasonably select a default option that is not quite right for you. This is a system issue, not a personal failure.

Signs that a prescription may need checking

You might want to query a prescription if:

• the dose or duration is different from what you usually receive

• it does not match what your specialist discussed

• it seems very short for a significant infection

• the pharmacist queries it

• you feel significantly worse after starting it

You do not need to know what the “correct” dose should be to ask for a review.

What to do — step by step

1. Do not ignore your concern
If something feels wrong, it is appropriate to pause and ask for clarification.

2. Speak to the pharmacist
Pharmacists are trained to spot dosing and duration issues. Ask:

• “Does this look right for someone with my condition?”

• “Could you check this against my previous prescriptions or clinic letters?”

Pharmacists can often contact the prescriber directly.

3. Contact the prescriber for a check
You can say:

• “I have a long-term lung condition and usually need non-standard dosing.”

• “Could this be checked against my specialist advice?”

This is a safety check, not a complaint.

4. Use trusted information sources
In the UK, the British National Formulary (BNF) lists usual doses and important side effects. You are not expected to interpret this alone, but it can help you explain your concern clearly.

5. If you are unsure, do not start or continue without advice
If you are worried about dose, duration, or side effects, seek medical advice urgently rather than continuing in uncertainty.

Why this matters for aspergillosis patients

In people with chronic lung disease:

• under-dosing can lead to treatment failure or relapse

• short courses may increase the risk of resistance

• symptoms may worsen and be misinterpreted as disease progression

From an antimicrobial stewardship (AMS) perspective, the right dose and duration are just as important as avoiding unnecessary antibiotics.

This is about partnership, not blame

Most prescribing issues happen because:

• systems default to standard settings

• clinicians work under extreme time pressure

• complex information is not always easy to see

Good care depends on patients, prescribers and pharmacists working together.

If safety depends on the patient spotting an error, the system needs improving — not the patient.

Key take-home message

If a prescription doesn’t look right for you, it is reasonable to ask for it to be checked.

Asking for clarification protects you and supports safer care for everyone.
