Summary
How the two Zopisign strengths differ, why a doctor might choose one over the other, and what that means for you.
On this page
Zopisign comes in two strengths in Australia, Zopisign 7.5mg and Zopisign 10mg, both containing the active ingredient zopiclone. The obvious question is why two strengths exist and how a doctor decides which one is right for a given patient.
The Core Difference Is Dose, Not the Medicine
Both tablets contain the same active ingredient and work through the identical mechanism, enhancing the calming effect of GABA in the brain to help with insomnia. The difference between them is simply the amount of zopiclone in each tablet, which affects the intensity of the sedating effect for a given person.
Neither strength is inherently "better". They exist to let a doctor tailor treatment to the individual, rather than applying a single dose to everyone regardless of age, sensitivity or how severe the insomnia is.
Why a Doctor Might Choose the Lower Strength
The 7.5mg strength is often the more conservative starting point, particularly for people who haven't taken zopiclone before, older adults, or anyone more sensitive to sedating medicines generally. Starting lower allows a doctor to see how a patient responds before considering any adjustment, which fits with the broader principle in prescribing sedatives of using the lowest effective dose for the shortest appropriate time.
People with reduced liver or kidney function, or those taking other medicines that might interact with zopiclone, are also more likely to be started on the lower strength as a precaution.
Why a Doctor Might Choose the Higher Strength
The 10mg strength may be considered when a lower dose hasn't provided adequate relief, or when a doctor judges from the outset that a stronger effect is clinically appropriate for a particular patient. This decision always sits with the prescriber, based on an individual assessment, not something to self-select based on how a previous course felt.
Never Switch Strengths on Your Own
Because zopiclone is a sedative with real risks around tolerance and dependence when used beyond a short course, moving between the 7.5mg and 10mg strengths should always be done under medical guidance rather than independently, even if you've used one strength before.
What Stays the Same Regardless of Strength
The general side effect profile, the advice to avoid alcohol, and the recommendation to use it for a short course rather than indefinitely all apply equally to both strengths, and both are covered on the zopiclone ingredient page.
Both strengths are supplied only against a valid prescription, and your pharmacist can talk you through exactly what's been prescribed and why, if anything is unclear.
Making the Right Choice for You
If you're unsure whether 7.5mg or 10mg is right for your situation, that's a conversation for your doctor, who will consider your age, health history, other medicines and the severity of your insomnia. You can browse both options and general information via the sleep aids category.
Always read the patient information leaflet for the specific strength you've been prescribed, and speak with your doctor or pharmacist if you have questions about your dose.
Frequently asked questions
Is Zopisign 10mg stronger than Zopisign 7.5mg?+
Yes, 10mg contains a higher dose of the same active ingredient, zopiclone, and generally produces a more pronounced sedating effect. The right strength depends on individual assessment by a doctor.
Can I switch from 7.5mg to 10mg on my own if 7.5mg isn't working?+
No, any change in strength should be discussed with and directed by your doctor, who can assess whether a higher dose is appropriate or whether another approach makes more sense.
Do older adults usually start on the lower strength?+
Often yes, since older adults and people more sensitive to sedatives are commonly started on a lower dose as a precaution, with adjustment only if a doctor decides it's needed.
