Unifen 200 is ibuprofen 200 mg, an anti-inflammatory painkiller. It is used for period pain, headache, backache, muscular and joint pain, dental pain, sprains and fever. Period pain is where it works particularly well, and the reason is worth understanding.
What is Unifen 200?
The South African Medicine Price Registry lists Unifen as a tablet containing ibuprofen:
| Product | Schedule | Strength |
|---|---|---|
| Unifen | S3 | Ibuprofen 200 mg |
| Unifen | S4 | Ibuprofen 400 mg |
The 200 mg strength is the standard lower dose; 400 mg is a higher-strength prescription version.
Ibuprofen is an NSAID — a non-steroidal anti-inflammatory. It blocks the cyclo-oxygenase enzymes that produce prostaglandins, the chemicals responsible for pain, swelling and fever at a site of inflammation.
Why it suits period pain specifically. Menstrual cramps are caused by prostaglandins driving the uterus to contract, and prostaglandin levels also correlate with how heavy the bleeding is. Ibuprofen reduces prostaglandin production, so it eases the cramping at its source rather than merely masking the pain — and it typically reduces menstrual blood loss as well.
Timing decides how well it works. Start it at the first sign of pain, or the day before a period is due if your cycle is predictable. Prostaglandins are far easier to prevent than to catch up with, and this single change makes more difference than the dose for most people.
The same mechanism produces its cautions. Prostaglandins also protect the stomach lining, support kidney blood flow and affect platelets — which is why NSAIDs carry stomach, kidney and cardiovascular risks. These are not incidental side effects but the direct consequence of how the medicine works.
What is Unifen 200 commonly used for?
- Period pain (dysmenorrhoea) — one of its best uses, and the one most searched.
- Heavy menstrual bleeding, where it reduces blood loss as well as pain.
- Headache and tension headache.
- Back, neck, muscular and joint pain.
- Sprains, strains and soft tissue injuries.
- Dental pain, including after extractions.
- Osteoarthritis and rheumatoid arthritis pain.
- Fever in adults.
- Cold and flu aches.
It is for short-term use unless a doctor has decided otherwise. Use the lowest dose that works, for the shortest time.
Persistently heavy or painful periods deserve a diagnosis, not indefinite symptom control. Fibroids, endometriosis, polyps, thyroid problems and clotting disorders are all treatable causes — and a painkiller that works well enough is a common reason they go unexamined for years. If period pain stops you working or studying, or is worsening month by month, that is worth investigating.
Medication-overuse headache is also worth knowing about: taking painkillers for headache more than about two or three days a week can itself cause headaches.
How Unifen 200 fits into this medicine category
| Group | Examples | Notes |
|---|---|---|
| NSAIDs | Ibuprofen (Unifen 200), diclofenac, naproxen, mefenamic acid | Pain with inflammation; particularly good for period pain |
| Simple analgesics | Paracetamol (Donapan) | Gentler; no anti-inflammatory effect |
| COX-2 selective | Celecoxib, etoricoxib | Anti-inflammatory, easier on the stomach |
| Antifibrinolytics | Tranexamic acid | Reduces menstrual bleeding without relieving pain |
| Hormonal treatment | Combined pill, hormonal IUD | Reduce pain and bleeding over the longer term |
| Corticosteroids | Prednisone | Inflammatory conditions, in courses |
For heavy painful periods, an NSAID and tranexamic acid are sometimes used together — one for the pain, one for the bleeding. See the pain, inflammation and musculoskeletal medicines hub.
What to check before using Unifen 200
Check every other product you take for an anti-inflammatory. Combination painkillers and cold remedies frequently contain ibuprofen, and doubling up substantially raises the risk of stomach bleeding.
Speak to a pharmacist or doctor if you:
- Have or have had a stomach ulcer, gastritis or bleeding in the digestive tract.
- Have asthma. A proportion of people with asthma react badly to NSAIDs, sometimes severely.
- Have heart disease, heart failure, high blood pressure or a history of stroke.
- Have kidney or liver disease.
- Take blood thinners, aspirin, another NSAID, steroids, SSRIs, diuretics, ACE inhibitors or lithium.
- Are pregnant. NSAIDs are generally avoided, and specifically avoided from 20 weeks. Tell your doctor if you are trying to conceive — NSAIDs can interfere with ovulation.
- Are breastfeeding, where ibuprofen is generally one of the more suitable options.
- Are over 65, where stomach and kidney risks rise.
- Are dehydrated, or have a vomiting or diarrhoea illness — NSAIDs and dehydration together are hard on the kidneys.
Practical points: take it with or after food; start early in a period and take it regularly through the worst days rather than sporadically; use the lowest effective dose; drink enough fluid; and if you take low-dose aspirin for your heart, ask a pharmacist about timing — ibuprofen can interfere with its protective effect.
Possible cautions and when to ask a pharmacist or doctor
Common effects are indigestion, heartburn, nausea, abdominal discomfort, headache and dizziness.
Get emergency help for:
- Vomiting blood, or material like coffee grounds.
- Black, tarry stools, or severe stomach pain.
- Sudden worsening of asthma, wheezing or breathlessness.
- Chest pain, breathlessness, or signs of a stroke — sudden weakness, facial droop, slurred speech or a severe unusual headache.
- Swelling of the face, lips or tongue, difficulty breathing, or a widespread blistering rash.
Contact a doctor if:
- Period pain is not controlled, or is worsening month by month.
- Bleeding is heavy enough to soak through protection hourly, you pass large clots, or you feel faint, breathless or exhausted — those suggest blood loss worth investigating for anaemia and its cause.
- You have bleeding between periods or after sex, or pelvic pain outside your period.
- Pain persists beyond a few days, or fever beyond three.
- You develop swollen ankles, reduced urine output or unexplained tiredness.
- Headaches are becoming more frequent — possible medication-overuse headache.
- You need it most days, or for ongoing pain.

Frequently asked questions
What is Unifen 200 used for? Period pain, headache, back and muscular pain, dental pain, sprains, arthritis pain and fever. It contains ibuprofen 200 mg.
Is Unifen 200 used for periods? Yes, and it works particularly well there. Period cramps are driven by prostaglandins, which ibuprofen reduces — so it eases the cramping at its source and typically reduces bleeding too.
When should I start taking it for period pain? At the first sign of pain, or the day before your period is due if your cycle is predictable. Starting early works considerably better.
What is the difference between Unifen 200 and 400? Only the amount of ibuprofen. The 400 mg version is a higher-strength prescription product.
Should I take it with food? Yes. Food reduces stomach irritation.
Can I take it with paracetamol? They are different medicines and are often used together on advice. Check that no other product you take already contains either.
Can I take it in pregnancy? Generally not. NSAIDs are avoided in pregnancy, particularly from 20 weeks. Ask your doctor about paracetamol instead.
Can I take it with asthma? Ask a pharmacist first. A proportion of people with asthma react badly to NSAIDs.
