How to read a medicine leaflet: what the package insert tells you
The leaflet inside a medicine pack tells you what the medicine is for, how to take it, who should not take it, which other medicines or foods to avoid, its side effects and how to store it. Read the warnings and the "stop and get help" section first, and ask your pharmacist about anything unclear. A missing or badly printed leaflet is also worth noticing when you check a pack.
What the leaflet is
Most registered medicines in Pakistan come with a folded paper insert, often called the package insert, patient information leaflet or simply the "parcha". Some are written for patients in plain language; others are written for doctors and pharmacists and are full of technical terms. Many are in English, and some include Urdu. The content is based on the product information approved when the medicine was registered.
The main sections, and what to look for
| Section (common names) | What it tells you | Why it matters |
|---|---|---|
| Composition | Active ingredient and strength, plus other ingredients | Confirms it matches your prescription; lists ingredients you may be allergic to |
| Indications / uses | What the medicine treats | Check it fits why you were given it |
| Dosage and administration | Usual doses and how to take it | Your doctor's instructions come first; this is the general guide |
| Contraindications | Who must not take it | Allergies, pregnancy, kidney or liver disease, children |
| Warnings and precautions | Who needs extra care | Driving, alcohol, older age, other illnesses |
| Interactions | Medicines and foods to avoid together | Includes common painkillers, antacids and herbal products |
| Side effects / adverse reactions | Effects that may occur, often by how common they are | Know which ones need urgent help |
| Overdose | What happens and what to do | Keep the pack if you seek help |
| Storage | Temperature, light and moisture | Heat damages many medicines; see our hot weather guide |
Reading the side effects without panicking
Leaflets must list every side effect that has been reported, even very rarely. A long list does not mean the medicine is dangerous for you. Many leaflets group effects by frequency: "very common" (more than 1 in 10 people), "common" (up to 1 in 10), "uncommon" (up to 1 in 100), "rare" (up to 1 in 1,000) and "very rare". Focus on two things:
- the effects described as needing you to stop and get medical help, such as swelling of the face or throat, difficulty breathing, severe rash, yellow skin or eyes;
- common effects that you can manage, like mild stomach upset, which the leaflet may say usually settles.
Do not stop a prescribed medicine on your own because of something you read; talk to your doctor or pharmacist. If you have a side effect, you can report it; see reporting side effects to DRAP.
Terms you will see
Leaflets use abbreviations: "b.d." (twice a day), "t.d.s." (three times a day), "o.d." (once a day), "p.r.n." (when needed), "a.c." (before food), "p.c." (after food). Our medicine glossary explains these and pack terms such as B. No., MFG and EXP.
What the leaflet can tell you about a suspicious pack
Leaflets are not a reliable test on their own, but they can add to other clues. Be more careful if:
- there is no leaflet in a full, sealed box that normally has one;
- the leaflet names a different product, strength or company from the carton;
- the print is blurry, photocopied, or full of spelling mistakes;
- the leaflet looks very different from one in a pack you bought before.
If you notice these, check the rest of the pack using our fake medicine checklist, scan the code and ask the pharmacist. See also what a medicine label must show.
When the leaflet and your doctor disagree
Doctors sometimes prescribe a dose or use that differs from the leaflet, for good reasons based on your situation. If your instructions look different from the leaflet, it is sensible to ask, but do not change the dose yourself. Write the doctor's instructions on the box so everyone at home knows how it should be taken.
Keep the leaflet
Keep the leaflet with the medicine until you finish it. It is useful if you have a reaction, if another doctor asks what you take, or if you need to check storage or missed-dose advice later.
A worked example
Say you were given an antibiotic syrup for your child. On the leaflet, check the composition matches the carton and the strength per 5 ml. Under dosage, note how the powder is mixed and how long the mixed syrup lasts. Under contraindications, look for allergy warnings, especially if your child has reacted to an antibiotic before. Under side effects, note that mild diarrhoea is common but a rash, swelling or difficulty breathing means stop and get help. Under storage, see whether it needs the fridge after mixing. Five minutes of reading answers most questions parents ask afterwards.
Pregnancy, breastfeeding and older age
Leaflets have separate sections for pregnancy and breastfeeding, and often for older people and those with kidney or liver problems. The wording is usually cautious. If you are pregnant, may be pregnant or are breastfeeding, tell the doctor and pharmacist before starting any medicine, including those sold without a prescription and herbal products. Do not decide from the leaflet alone.
Reading leaflets for someone else
Many families in Pakistan have one person who reads and manages medicines for parents or grandparents. Writing the key points on the box in Urdu, such as "subah 1, raat 1, khane ke baad", and keeping a single list of all their medicines with generic names, prevents mix-ups and double doses.

Questions people ask
What is a medicine leaflet?
It is the folded paper inside the pack, also called the package insert or patient information leaflet. It describes what the medicine is for, how to take it, who should not take it, side effects and how to store it.
What if there is no leaflet in the pack?
Ask the pharmacist. A missing leaflet is not proof of a fake, as strips are sometimes sold without the box, but combined with other warning signs it is a reason to check the pack carefully.
The leaflet lists many side effects. Should I stop the medicine?
No. Leaflets list every side effect reported, including very rare ones. Read the "stop and get help" warnings carefully, and talk to your doctor or pharmacist before stopping a medicine on your own.
Dawa ke parche par kya dekhna chahiye?
Dawa kis liye hai, kitni aur kab leni hai, kaun na le, kin dawaon ke saath na lein, side effects, aur kaise rakhni hai. Samajh na aaye to pharmacist se poochein.
