Pharmacy Sold You Expired, Duplicate or Wrong Medicine? Complaint and Refund Guide

Who this guide is for

This guide is for anyone in India who bought medicine from a pharmacy or chemist and discovered something wrong with it. The most common situations are:

• Expired medicine: The expiry date on the strip or box had already passed when the chemist sold it to you.
• Duplicate or counterfeit medicine: The pack looks fake, the printing is poor, the batch number is missing, or the medicine behaves strangely.
• Wrong medicine dispensed: The chemist gave you a different drug, the wrong strength, or a different brand than your prescription stated.
• Tampered or spoiled medicine: The seal was broken, tablets were loose, or a liquid had changed colour or smell.

It is written for the patient or the family member who bought the medicine. If you took the medicine and feel unwell, your first step is medical, not legal — see a doctor or go to a hospital, and only then deal with the complaint. The amount you paid may be small, but a bad batch of medicine can affect many people, so reporting it matters beyond your own refund.

This guide covers private pharmacies and chemists. The shop is a private business, so the main routes are the consumer commission and the State drug regulator, not RTI against the shop itself. We explain where RTI does and does not help further down.

What you can do this weekend

Friday evening

Stop using the medicine immediately. Do not throw away the strip, the box, the cotton, the leaflet, or anything that came with it. These are your evidence. If you have already taken a dose and feel any symptom, treat that as the priority and seek medical help.

Find your bill or cash receipt. If the chemist did not give you a bill, write down the date, time, amount paid, and the shop's name and address while it is fresh in your memory. Note who served you if you can.

Photograph everything clearly. Take close-up photos of the expiry date, the batch number, the manufacturing date, the manufacturer name, the price, and any damage or odd printing. Lay the strip next to the bill in one photo so the link is obvious. Save these photos in a folder you will not lose.

Saturday

Read your prescription again and compare it word for word with what you were given. Check the drug name, the strength in milligrams, the form (tablet, syrup, injection), and the quantity. A small difference in strength can matter a great deal, so do not assume it is fine.

Go back to the pharmacy in person, calmly, with the medicine and the bill. Tell them exactly what is wrong. Most genuine chemists will refund or replace expired or wrong medicine on the spot. Ask for the refund or replacement and a written acknowledgement of the return. If they refuse, do not argue at length — note the name of the person, the date and time, and what was said.

If you suspect a duplicate or counterfeit, do not return the only pack and walk away with nothing in writing. Keep at least your photos and bill copy. A genuine pack and bill are what let the drug inspector trace the batch.

Sunday

Draft your written complaint. Use the template in this guide as a starting point. Keep it factual: what you bought, when, the batch number, what was wrong, and what you want (refund, replacement, action against the shop).

Find the right offices. Look up your State Drugs Control department or Food and Drugs Administration online and note the district or zonal drug inspector's contact. Note your district consumer commission as well. You can also note the manufacturer's customer care, printed on the pack, to report a suspected fake batch directly to them.

Organise your evidence into one bundle: bill, photos, prescription, the medicine itself in a safe bag, and a short timeline of what happened. Keep the originals safe and use copies for submissions. You are now ready to send the complaints on Monday.

Documents and evidence checklist

Step-by-step action plan

Step 1 — Stop using it and preserve the evidence

The single most important action is to stop taking the medicine and keep everything. Place the strip, box and leaflet in a clean bag. Do not wash, peel or damage the pack. Photograph the expiry date, the batch number and any defect from several angles. If you discard the pack, you lose the ability to prove the defect and to trace the batch.

Step 2 — Confirm what exactly is wrong

Be precise about the problem. For expiry, read the printed expiry date and compare it to your purchase date. For a wrong medicine, line up the prescription against the pack name, strength and form. For a suspected duplicate, look for spelling errors, blurred or smudged printing, a missing or odd batch number, an unusually low price, loose tablets, or a strange smell. A clear description of the exact defect makes every later complaint stronger.

Step 3 — Approach the pharmacy for a refund or replacement

Return to the shop with the medicine and the bill. Ask for a refund or a correct replacement and a written acknowledgement that you returned the defective item. Selling expired or fake medicine is a serious offence, so most chemists settle quickly to avoid a complaint. Keep your photos and a bill copy even if you hand back the pack. If the chemist cooperates fully, you may not need to escalate — but still consider reporting an expired or fake batch so the rest of that lot is checked.

Step 4 — Report to the drug inspector / State Drugs Control

If the shop refuses, or if the medicine was expired, tampered or appears counterfeit, report it to the drug regulator. Each State has a Drugs Control department or Food and Drugs Administration, with drug inspectors for each district or zone. Submit a written complaint with your bill copy, the batch number and your photographs. The drug inspector can inspect the shop, draw samples of the batch for testing, check the shop's purchase records, and act against the licence if the law was broken. This is the route that protects other patients, because the inspector can have the whole batch tested and recalled.

Step 5 — Verify a suspected duplicate with the manufacturer

If you suspect a counterfeit, contact the manufacturer using the customer-care details on the pack. Give them the batch number and product name. The manufacturer can often confirm whether that batch is genuine and whether it was actually produced by them. Their written reply is powerful evidence for the drug inspector and the consumer commission. For background on how fake-medicine networks operate and how India tackles them, see our explainer on pharmacy fraud and fake medicines in India.

Step 6 — Send a written demand for refund and compensation

If the shop did not refund you, send a written demand (the template below helps). State what you bought, the defect, the batch number, and what you want — refund, and compensation if you were harmed. Send it by a method that gives proof of delivery, and keep a copy. A written demand often gets a response where a verbal request did not, and it is also a useful step before approaching the consumer commission.

Step 7 — File a consumer complaint if needed

If you are not refunded or compensated, you can file a complaint before the consumer commission against the pharmacy for selling defective goods or deficient service. Complaints can usually be filed at the district, state or national level depending on the value claimed, and online filing is available through the national consumer portal. Attach your bill, photos, prescription, the manufacturer's reply if any, and medical records if you fell ill. For health harm, take legal advice on the compensation you can claim.

Step 8 — Follow up and keep records

Track every complaint by its reference or ticket number. Note the dates you sent each letter and the dates of any reply. If the drug inspector does not respond, follow up in writing and escalate to the senior drug controller of your State. Keep your evidence bag and all copies until the matter is fully closed.

When RTI can help

The Right to Information Act, 2005 applies to public authorities. Your local pharmacy is a private business, so you cannot file RTI against the shop. But the drug regulator is a public authority, and that is where RTI becomes useful once you have already complained. RTI can help you in these specific situations:

• Finding out what action was taken: If you complained to the drug inspector and heard nothing, file an RTI with the State Public Information Officer of the State Drugs Control department. Ask what action was taken on your complaint, whether samples of the batch were drawn, and the result of any test.
• Checking the pharmacy's licence: Ask whether the shop holds a valid drug sale licence, and whether any action, suspension or cancellation has been recorded against it. This shows whether the shop was even allowed to sell medicine.
• Batch testing and recall status: If you suspect a wider problem, ask whether the batch number was tested anywhere in the State and whether any recall or warning was issued for it.

To file an RTI, see our step-by-step guide on how to file an RTI online in India. The public information officer must reply within the timeline set by the RTI Act, generally 30 days. If you get no reply or an unsatisfactory one, you can use our guide to file a first appeal under RTI Section 19. For deeper strategy on combining RTI with other complaints, see The RTI Playbook and our overview of CPGRAMS and RTI used together.

When RTI will not help

RTI has clear limits in a medicine dispute:

• RTI cannot get your refund: RTI only gives you information from the government. It cannot order the pharmacy to refund you or pay compensation. For that, use the pharmacy directly, then the consumer commission.
• RTI does not apply to the shop or the manufacturer: These are private bodies. You cannot demand their internal records through RTI. Deal with the shop directly and write to the manufacturer's customer care.
• RTI is slower than the direct routes: If your priority is a quick refund or stopping a dangerous batch, the pharmacy, the drug inspector and the manufacturer are faster than waiting for an RTI reply. Use RTI to track and confirm action, not as your first move.

Common mistakes to avoid

• Throwing away the strip or box: Without the pack and the batch number, the defect cannot be proven and the batch cannot be traced. Keep everything.
• Not getting a bill: Always insist on a bill. Without proof of purchase, both the refund and the complaint become much harder. If you have no bill, note every detail you remember at once.
• Continuing to take the medicine: If it is expired, fake or wrong, stop immediately. Your health comes before any refund.
• Only chasing the small refund: The few rupees you paid matter less than the safety of the whole batch. Report expired or fake medicine to the drug inspector so others are protected.
• Returning your only evidence with nothing in writing: If you hand back the pack, keep your photos and a bill copy, and get the return acknowledged in writing.
• Ignoring symptoms: If you feel unwell after taking the medicine, see a doctor and keep the records before worrying about the complaint.
• Assuming a low price is a bargain: A medicine sold far below market price can be a sign of a duplicate or a diverted, expired stock. Be cautious and check the pack.
• Filing RTI against the pharmacy: RTI does not apply to private shops. Use it only with the State drug regulator to track action.
