Adco-Dol is a compound painkiller containing paracetamol, caffeine, codeine and doxylamine. It is taken for tension headache, body aches and cold and flu pain. It is not an antibiotic, despite the category it appears in — it contains nothing that treats infection.
What is Adco Dol?
The South African Medicine Price Registry lists Adco-Dol as a Schedule 2 tablet — available from a pharmacy without a prescription, with the pharmacist involved:
| Ingredient | Amount | What it does |
|---|---|---|
| Paracetamol | 450 mg | Pain relief and fever reduction |
| Caffeine | 45 mg | Mild stimulant; enhances the painkillers |
| Codeine phosphate | 10 mg | Opioid pain relief |
| Doxylamine succinate | 5 mg | Sedating antihistamine; muscle relaxation |
A note on placement. This page sits among the antibiotic guides because of how the source catalogue was organised. That is misleading: Adco-Dol is a painkiller, and it contains no antibiotic and nothing that acts on infection. If you were given it for an infection, check the pack — the antibiotics and antimicrobials hub covers the medicines that genuinely treat one.
It is a compound analgesic of a type common in South Africa — Tensopyn, Codoxol, Mybulen and Stopayne are relatives with varying combinations.
Each ingredient contributes, and each brings its own cautions:
Paracetamol is the backbone, acting centrally on pain and fever.
Codeine is a weak opioid, converted by the liver into morphine — which is what actually relieves pain. How efficiently people convert it varies widely by genetics; some get little benefit, a few convert rapidly and experience marked opioid effects at ordinary doses.
Caffeine modestly enhances the painkillers and offsets some drowsiness.
Doxylamine is a sedating antihistamine adding muscle relaxation and sedation.
What is Adco Dol commonly used for?
- Tension headache — the commonest reason people buy it.
- Migraine, for symptom relief.
- Body aches and muscular pain, including spasm and backache.
- Cold and flu symptoms — aches, headache, fever and runny nose.
- Period pain.
- Toothache, as short-term relief while awaiting dental treatment.
- Pain after minor injury.
It suits pain with a tension or muscular component, which is where the combination earns its place over plain paracetamol.
It is for occasional, short-term use — a few days at most. Two problems follow from regular use:
Dependence. Codeine is an opioid, and daily use of codeine-containing painkillers produces physical dependence within weeks. This is common, it happens to ordinary people managing ordinary pain, and it is among the most frequent medicine problems South African pharmacists see.
Medication-overuse headache. Taking painkillers for headache more than about two or three days a week can itself cause headaches — a cycle in which the treatment sustains the problem. Codeine-containing products are particularly prone to it.
How Adco Dol fits into this medicine category
Adco-Dol belongs with the analgesics, not the antimicrobials:
| Group | Examples | Notes |
|---|---|---|
| Compound analgesics | Adco-Dol, Tensopyn, Codoxol, Mybulen | Several ingredients; codeine cautions apply |
| Simple analgesics | Paracetamol | No dependence risk; better for regular use |
| Anti-inflammatories | Ibuprofen, diclofenac | Better for inflammatory pain; stomach cautions |
| Antibiotics | Amoxicillin, azithromycin (Azrotrin) | Bacterial infection — a different problem entirely |
| Antiprotozoals | Metronidazole | Anaerobic and parasitic infections |
If your pain is occasional and mild, plain paracetamol carries none of the codeine problems.
What to check before using Adco Dol
Check everything else you take for paracetamol. It appears in a great many cold and flu remedies, sinus products and other painkillers. Taking Adco-Dol alongside one of them means taking paracetamol twice — the commonest route to serious accidental overdose.
Check for codeine too. Doubling up adds sedation and dependence risk.
Speak to a pharmacist or doctor if you:
- Have liver disease, or drink alcohol heavily.
- Have kidney disease, or weigh under 50 kg.
- Have breathing problems — asthma, COPD, sleep apnoea. Codeine suppresses breathing.
- Take sedating medicines — benzodiazepines, sleeping tablets, other opioids, gabapentin or pregabalin. These combinations meaningfully raise the risk of dangerously slowed breathing.
- Take MAOI antidepressants, or have in the past fortnight.
- Have glaucoma, an enlarged prostate or difficulty passing urine — relevant to doxylamine.
- Have a history of dependence on opioids, alcohol or other substances.
- Have constipation or a bowel condition.
- Are pregnant or breastfeeding. Codeine is generally avoided in breastfeeding, because a mother who converts it rapidly can pass unsafe amounts of morphine into her milk.
- Are elderly, where sedation and falls are a greater risk.
Do not give it to children. Codeine is not recommended in children. Do not drink alcohol with it, and do not drive until you know how it affects you.
Possible cautions and when to ask a pharmacist or doctor
Common effects are drowsiness, dizziness, dry mouth, constipation, nausea and difficulty concentrating. Constipation is very common with codeine and does not settle on its own.
Get emergency help for:
- Suspected paracetamol overdose. This is the most dangerous scenario and the least obvious — someone who has taken too much may feel entirely well for a day or more while serious liver damage develops. Go to an emergency department immediately with the packaging, even if they seem fine and even if it was accidental. There is an effective antidote and it works best given early.
- Very slow, shallow or difficult breathing, extreme drowsiness or unresponsiveness.
- Swelling of the face, lips or tongue, difficulty breathing, or a widespread blistering rash.
Contact a doctor if:
- You are using it more than two or three days a week, or for more than a few days at a time.
- You feel you cannot manage without it, or take more than the pack allows. This is common, treatable, and pharmacists deal with it without judgement.
- Headaches are becoming more frequent — possible medication-overuse headache.
- Pain persists beyond a few days, fever beyond three, or symptoms worsen after improving.
- You develop a sudden severe headache, headache with fever and a stiff neck, weakness, confusion, visual changes, or headache after a head injury.
- You were given it expecting an antibiotic — it is not one, and an infection needs different treatment.

Frequently asked questions
What are Adco-Dol tablets used for? Tension headache, migraine, body and muscular aches, period pain, toothache, and the pain and discomfort of colds and flu.
Is Adco-Dol an antibiotic? No. It contains paracetamol, caffeine, codeine and doxylamine — a painkiller combination with nothing that treats infection.
Do I need a prescription? No. It is Schedule 2 — available from a pharmacy without one, with the pharmacist’s involvement.
Is it addictive? It contains codeine, an opioid, and regular use leads to dependence. It is intended for short-term use only.
Why does it make me drowsy? Both the codeine and the doxylamine are sedating. Do not drive until you know how it affects you, and avoid alcohol.
Can I take it with another painkiller? Check the ingredients first. Many contain paracetamol or codeine already, and doubling up on either is dangerous.
Can I give it to my child? No. Codeine is not recommended for children.
How long can I take it for? A few days at most. Persistent pain needs a diagnosis rather than continued self-treatment.
