Synaleve is a prescription medication widely used in South Africa to treat moderate to severe pain. It is a combination drug that contains three active ingredients:
Active Ingredient | Strength per Capsule | Role |
---|---|---|
Paracetamol | 400 mg | Pain relief and fever reduction |
Codeine Phosphate | 8 mg | Mild opioid for enhanced pain relief |
Meprobamate | 200 mg | Tranquilizer with sedative and muscle relaxant properties |
Each of these components works synergistically to alleviate pain while addressing the associated symptoms of tension and discomfort.
Uses of Synaleve

Synaleve is primarily prescribed for the following:
- Acute Pain Relief:
- Suitable for conditions like headaches, migraines, and dental pain.
- Used post-surgically to manage moderate to severe pain.
- Chronic Pain Management:
- Provides relief for conditions such as arthritis, musculoskeletal pain, and back pain.
- Tension Relief:
- The meprobamate component helps reduce anxiety and tension often associated with pain.
- Adjunct Therapy:
- Can be used alongside other medications for comprehensive pain management, provided there are no overlapping ingredients that could lead to overdose.
How Synaleve Works
Component | Mechanism of Action |
---|---|
Paracetamol | Inhibits the production of prostaglandins in the brain, reducing pain signals and lowering fever. |
Codeine Phosphate | Converts to morphine in the body to bind opioid receptors, providing analgesic effects for moderate pain. |
Meprobamate | Acts on the central nervous system to produce calming effects, reducing muscle tension and promoting relaxation. |
Dosage and Administration Synaleve
Parameter | Details |
---|---|
Typical Dosage | 1-2 capsules every 4-6 hours as needed, not exceeding 8 capsules per day. |
Route of Administration | Oral, taken with or after food to reduce stomach upset. |
Duration | Use as directed by a healthcare professional. Avoid prolonged use without medical supervision. |
Precautions Before Use Synaleve
1. Medical History
- Liver or Kidney Disease: Avoid Synaleve if you have severe liver or kidney impairments due to the risk of toxicity, especially from paracetamol.
- Respiratory Conditions: Conditions such as asthma or chronic obstructive pulmonary disease (COPD) may be exacerbated by codeine, which can depress respiration.
- Substance Abuse History: Codeine can be habit-forming; avoid in individuals with a history of addiction.
2. Pregnancy and Breastfeeding
- Not recommended during pregnancy due to potential risks to the fetus, including respiratory depression.
- Codeine passes into breast milk, potentially causing drowsiness or breathing difficulties in the infant.
3. Drug Interactions
- Avoid combining Synaleve with:
- Other CNS Depressants: Alcohol, sedatives, or tranquilizers can amplify drowsiness and respiratory depression.
- Medications Containing Paracetamol: Increases the risk of liver damage due to cumulative doses.
- Monoamine Oxidase Inhibitors (MAOIs): May result in dangerous interactions.
4. Driving and Machinery Operation
- Avoid activities requiring alertness, as Synaleve may cause drowsiness, dizziness, or impaired coordination.
Side Effects Synaleve
Category | Side Effect | Frequency |
---|---|---|
Common | Nausea, vomiting, drowsiness, constipation | Frequent |
Less Common | Dizziness, dry mouth, mild skin rash | Occasional |
Serious | Respiratory depression, severe liver damage | Rare but critical |
Allergic Reactions | Swelling, itching, difficulty breathing (anaphylaxis) | Very rare |
Managing Side Effects
- Nausea or Vomiting: Take Synaleve with food or a glass of milk.
- Constipation: Increase fiber intake and stay hydrated.
- Drowsiness or Dizziness: Avoid operating heavy machinery and rest in a safe environment.
- Signs of Liver Damage: Jaundice (yellowing of the skin/eyes), dark urine, or persistent fatigue warrants immediate medical attention.
Overdose Risks Synaleve
Taking more than the prescribed dose can result in serious health complications:
Overdose Symptom | Likely Cause | Action Required |
---|---|---|

- Severe Liver or Kidney Dysfunction: Risk of toxicity is heightened.
- Known Allergy: To any of the active ingredients or excipients.
- Respiratory Depression: Conditions that impair breathing.

Drug Interactions Synaleve
1. Central Nervous System Depressants
- Combining Synaleve with alcohol, benzodiazepines, or other sedatives can dangerously suppress breathing and alertness.
2. Medications Containing Paracetamol
