Doloact MR (Chlorzoxazone/Diclofenac/Paracetamol) in Kenya

Product Description

Product Summary

Doloact MR is a prescription combination medication containing:

• Chlorzoxazone (500mg): Muscle relaxant for spasms.
• Diclofenac Potassium (50mg): NSAID for pain/inflammation.
• Paracetamol (Acetaminophen) (325mg): Analgesic/antipyretic.
  Used for musculoskeletal pain (e.g., back pain, arthritis, sprains) with muscle spasms. The “MR” (Modified Release) formulation provides sustained relief over 8–12 hours. Available in Kenyan pharmacies with a prescription.

Composition

Inactive Ingredients:
Microcrystalline cellulose, magnesium stearate, colloidal silicon dioxide.

Key Uses

• Muscle Spasms with Pain: Lower back pain, neck stiffness, sports injuries.
• Inflammatory Conditions: Osteoarthritis, rheumatoid arthritis, tendonitis.
• Post-Traumatic Pain: Sprains, strains, fractures.

How to Use

Dosing Guidelines

• Adults: 1 tablet twice daily (morning/evening).
• Max Duration: 7–10 days (long-term use increases risks).
• Administration:
  • Take with food to reduce GI upset.
  • Swallow whole; do not crush/chew (alters MR release).

Special Populations

• Elderly: Start with 1 tablet daily; monitor renal function.
• Renal/Hepatic Impairment: Avoid or reduce dose (diclofenac/paracetamol risks).

Potential Side Effects

Common

• GI Issues: Nausea, dyspepsia, abdominal pain (diclofenac-related).
• Dizziness/Drowsiness: Chlorzoxazone CNS effects (avoid driving).
• Elevated Liver Enzymes: Paracetamol/diclofenac hepatotoxicity.

Serious Risks

• GI Bleeding: Ulcers/perforation (risk higher in elderly, history of ulcers).
• Hepatotoxicity: Paracetamol overdose (>4g/day) or chronic use.
• Renal Impairment: Diclofenac reduces blood flow to kidneys.
• Allergic Reactions: Rash, angioedema (discontinue immediately).

Precautions & Interactions

Avoid if:

• Active peptic ulcer, severe liver/kidney disease.
• Asthma, aspirin sensitivity, or bleeding disorders.
• Pregnancy (3rd trimester – diclofenac causes fetal harm).

Drug Interactions

• Anticoagulants (e.g., warfarin): Increased bleeding risk.
• Other NSAIDs/Paracetamol: Risk of overdose/toxicity.
• Alcohol: Accelerates liver damage.
• Antihypertensives: Diclofenac reduces efficacy.

Pregnancy/Breastfeeding

• Category C: Avoid unless essential (diclofenac risks fetal renal dysfunction).
• Breastfeeding: Paracetamol/diclofenac excreted in milk (avoid or use alternatives).

Frequently Asked Questions

1. Is Doloact MR available over-the-counter in Kenya?
   No – prescription-only. Available at pharmacies (e.g., Goodlife, Meds).

2. How much does it cost?
   ~KES 80–150 per tablet. Monthly cost (2/day): ~KES 4,800–9,000.

3. Why use a combination instead of single drugs?
   Targets pain + inflammation + spasms simultaneously; improves compliance.

4. Can I take it for headaches?
   Not ideal – reserved for musculoskeletal pain. Use paracetamol/ibuprofen instead.

5. What if I miss a dose?

6. Are there Kenyan alternatives?
   Yes – Myoril (chlorzoxazone alone), Voltaren (diclofenac), or Panadol (paracetamol).

7. Does it cause addiction?
   No – chlorzoxazone is not addictive; diclofenac/paracetamol have no abuse potential.
