Meprobamate is an older medicine that slows down activity in the brain and nervous system. It has been used for anxiety, tension, sleep problems, and muscle-related discomfort, but today it is used much less often because it can cause drowsiness, dependence, withdrawal, and overdose risk.
In South Africa, meprobamate may also be found in some combination pain tablets, often together with ingredients such as paracetamol, codeine, and caffeine.
Is meprobamate legal in South Africa?
Yes, but it is controlled. Meprobamate is listed as a Schedule 5 medicine in South Africa, which means it should only be used under medical supervision and according to a valid prescription.
Why do people need to be careful with it?
Meprobamate can make a person feel calm or sleepy, but it can also affect judgement, balance, breathing, and alertness. People using meprobamate should be careful when driving, operating machinery, or doing any activity that requires full concentration.
A major concern is that the body can get used to meprobamate. This means a person may need more to feel the same effect, and stopping suddenly after regular use can cause withdrawal symptoms.
Common side effects
Possible side effects include:
- Sleepiness or tiredness
- Dizziness or poor coordination
- Confusion or slowed thinking
- Nausea or stomach discomfort
- Skin rash or itching
- Constipation, especially if the tablet also contains codeine
Rare but serious side effects can include severe allergic reactions and blood-related problems. Any unusual bruising, bleeding, fever, sore throat, severe rash, or trouble breathing should be treated as urgent.
Who should be extra careful?
Speak to a doctor or pharmacist before using meprobamate, especially if you:
- Are elderly or frail
- Are pregnant, planning pregnancy, or breastfeeding
- Have liver or kidney problems
- Have depression, substance-use problems, or a history of dependence
- Take sleeping tablets, anxiety medicines, strong pain medicines, antihistamines, antidepressants, alcohol, or other sedating medicines
- Need to drive, operate machinery, or do safety-sensitive work
Do not mix with alcohol
Avoid alcohol while using meprobamate. Alcohol can increase sleepiness, poor coordination, impaired judgement, and breathing problems.
This is especially important because some South African combination pain tablets may also contain codeine, which can also cause drowsiness and breathing problems when misused or combined with alcohol.
Overdose warning
An overdose of meprobamate can be dangerous. Warning signs may include:
- Extreme sleepiness
- Confusion
- Loss of balance
- Slow or difficult breathing
- Collapse
- Unconsciousness or coma
In South Africa, for a suspected overdose or poisoning, seek urgent medical help immediately. You can call emergency services or go to the nearest emergency unit.
Safe-use tips
Use meprobamate only if it was prescribed for you. Do not share it with anyone else. Do not take extra tablets to “make it work better.”
Do not stop long-term use suddenly unless your doctor tells you how to reduce it safely.
Store it in a locked place, away from children, teenagers, and anyone who may misuse medicines. Combination pain tablets can look harmless, but ingredients like paracetamol, codeine, caffeine, and meprobamate can be risky when taken incorrectly.
Reporting side effects in South Africa
Report serious or unusual side effects to your doctor or pharmacist. Side effects can also be reported through South Africa’s medicine safety reporting channels.
Key message
Meprobamate is not an everyday “simple painkiller” or harmless calming tablet. In South Africa, it is a controlled medicine and should be used only under professional guidance.
The biggest risks are sleepiness, accidents, dependence, withdrawal, dangerous interactions, and overdose.
