TL;DR – How to Dispose of Old Medication in Singapore
- Best & safest option: Return unused or expired medicines to any medical clinic – it’s free.
- Controlled drugs (strong painkillers, sleeping pills, etc.): Must be returned to a medical clinic.
- Never flush medicines down the toilet or pour them down the sink – it harms the environment and contributes to AMR.
- Home disposal (only if you can’t return): Mix tablets with coffee grounds or cat litter, seal in a bag, and throw in regular trash.
- Sharps/needles & inhalers: Use a sharps container (available at pharmacies) and return for safe disposal.
- Bring them to MMC Clinic: We accept returns during operating hours – no appointment needed.
At MMC, we often see patients with leftover or expired medications cluttering their cabinets. Proper disposal of old medication is crucial to prevent accidental misuse, protect children and pets, and safeguard Singapore’s environment from pharmaceutical pollution.
Why should you Dispose of Old Medication properly?
Improper disposal of medicines can lead to water contamination and contribute to antimicrobial resistance (AMR). It’s a growing public health threat in Singapore.
According to Singapore’s National Strategic Action Plan on AMR (NSAPv2, launched November 2025), responsible disposal helps preserve the effectiveness of antibiotics and other antimicrobials.
When Should I dispose Expired/Unused Medication?
You should consider disposing of your medications immediately if:
- They are expired or if the expiration date is uncertain, such as when the packaging is damaged or a section of the blister pack is missing.
- Their shelf life has been compromised, for instance, due to inappropriate storage conditions.
- They exhibit signs of degradation like changes in color, odor, or texture.
- The medication is no longer needed by the prescribed individual and isn’t intended for occasional use as needed.
What to do with most Non-Controlled Medications
For tablets, capsules, syrups, creams, and ointments that are not controlled drugs (over the counter medication):
- Return them to any participating pharmacy (most community pharmacies accept them free of charge).
- Pharmacies send them for safe, high-temperature incineration, which is the most environmentally responsible method in Singapore.
What to do with Controlled Drugs and Special Cases
Controlled drugs (e.g., strong painkillers like morphine, codeine, or certain sleeping pills) must be returned to a pharmacy, hospital pharmacy or clinic for secure disposal under the Misuse of Drugs Act. Do not throw them in the trash or flush them.
What to do with Inhalers, needles, and other items
- Inhalers:
Do not throw them in the bin—residual propellant and medication can harm the environment.
Return to a pharmacy or use a designated collection point.
- Needles/syringes:
If you have needles at home, place them in a puncture-proof sharps container (available from pharmacies or Amazon) and return to a clinic or pharmacy for safe disposal.
Where to return Medications in Singapore
- Most community pharmacies (Guardian, Watsons, Unity, etc.) accept unwanted medicines.
- Public hospitals and polyclinics often have dedicated drop-off points.
- Best is to return it to the clinic that prescribed it to you. (Check with them just in case.)
- Mission Medical Clinic also accepts medicine disposal during operating hours.
What if I need to Dispose at home?
If returning is not possible:
- Remove medicines from original packaging.
- Mix tablets/capsules with an unpalatable substance (e.g., used coffee grounds, cat litter, or dishwashing liquid).
- Place the mixture in a sealed plastic bag or container.
- Throw in your household trash (not the recycling bin or toilet).
- Remove personal information from packaging before disposal.
Never flush medicines down the toilet or pour liquids down the sink—this contaminates water sources and contributes to AMR.
