What this medicine information covers
The Sialanar licence covers severe drooling due to chronic neurological disorders of childhood onset in patients aged 3 and older. It requires an experienced prescriber. Its solution contains 400 micrograms/ml glycopyrronium bromide, equivalent to 320 micrograms/ml glycopyrronium. These salt/base descriptions refer to the same solution, not two interchangeable dosing instructions.

An oral solution must be checked product by product
Sialanar must not be swapped with other glycopyrronium products on a microgram-for-microgram basis without the necessary dose adjustment. Tablets and oral solutions are also distinct preparations. Give the pharmacy the name, concentration and labelled volume from the current prescription. If the product offered differs, the pharmacist and prescriber must establish the correct instructions; do not calculate a replacement volume yourself.

Details to check on your current prescription
- The complete brand or manufacturer's name.
- Whether the prescription is for tablets or an oral solution.
- The concentration exactly as written, including units per ml or per 5 ml.
- The quantity needed and, for a liquid, the remaining volume.
- Whether the current bottle has an opening date or an after-opening expiry on its label.
Keep the original wording available. You do not need to upload a prescription or disclose a diagnosis to read this guide. If records are needed for a pharmacy discussion, the team will explain how to provide them.
Two labels appear to show different strengths
It is easy for a carer to copy a number from a carton while another person reads a different number from a prescription. Send neither number as a guess. Keep the original wording available and ask the pharmacist to check it. Once the clinical team confirms a plan, make sure all carers use the same current instructions and measuring device. A supply enquiry should never create a second, informal set of dosing directions.
Organising the next repeat
Before the next repeat request, check the usable supply rather than only whether a bottle is physically present. An open bottle may have an after-opening limit, and a medicine cabinet may contain an older concentration. Tell the pharmacy about the current product and ask how much time it needs to check the next prescription. If a care setting is involved, make sure its administration record and the dispensing label agree before the next supply is used.
Safety and clinical advice
When a clinical conversation comes first
Important anticholinergic effects include constipation, difficulty passing urine, dry mouth, fever and overheating. Follow the supplied safety plan. For constipation, urinary retention, pneumonia, fever or a significant behavioural change, the tablet product information advises stopping treatment and contacting the prescriber. Check the instructions for the actual product; severe breathing difficulty or a serious allergic reaction needs emergency help.

Prescription questions people ask
Are 320 micrograms/ml and 400 micrograms/ml always two different liquids?
For Sialanar, they describe glycopyrronium base and glycopyrronium bromide in the same solution. Other products still need individual checks; do not use those numbers to make a dose conversion.
Can tablets replace an oral solution?
Not on the basis of this page. A formulation change requires the appropriate clinical and prescription checks.
Does this guide cover glycopyrronium inhalers?
No. An inhaler is a different preparation. Make the route and formulation clear when you ask a pharmacy a question.
What should a carer have ready?
The current product name, concentration, dispensing label, remaining usable supply and prescription status. Share personal records only through the route agreed with the pharmacy.
Can I choose a larger bottle to reduce the number of deliveries?
The supplied quantity must follow a valid prescription and the product's storage and expiry requirements. Discuss practical arrangements with the pharmacy rather than changing the request yourself.
Are all tablets licensed for the same patients and uses?
Product licences must be checked individually. Do not assume that a generic ingredient name makes every product suitable for the same person.
UK prescription questions
Understanding supply and repeat arrangements in the UK
The formulation is essential to a UK supply check
The name glycopyrronium alone is not enough to identify the medicine. Copy the full product name, strength or concentration and pharmaceutical form from the current prescription. For a liquid, preserve the exact units. A different concentration is not a routine replacement to choose yourself.
Organising supplies with a patient or carer
Tell the pharmacy which team manages the existing prescription and whether a supply is already in progress. Ask how collection or delivery can be coordinated with the person receiving it. Product licences and instructions differ, so take questions about suitability or a changed product to the appropriate clinical team.
