# Meftal-Spas
## Overview
Meftal-Spas is a combination medication containing **Mefenamic Acid** (an NSAID, 250 mg) and **Dicyclomine Hydrochloride** (an antispasmodic/anticholinergic, 10 mg). It is used for the symptomatic relief of pain associated with smooth muscle spasms.
## Primary Indications
* Primary dysmenorrhea (menstrual cramps).
* Abdominal cramps and gastrointestinal spasms.
* Spasmodic pain associated with pelvic conditions.
## Adult Dosing
* **Standard Dose:** 1 tablet (250 mg Mefenamic Acid / 10 mg Dicyclomine) taken 3 to 4 times daily.
* **Maximum Dose:** Do not exceed 4 tablets in 24 hours.
* **Duration:** Limit use to the shortest duration necessary, typically not exceeding 3–5 days for acute pain.
## Pediatric Dosing
* **Safety Note:** Use is generally **not recommended** in children due to the Mefenamic Acid component (risk of Reye-like syndrome, renal toxicity) and Dicyclomine (risk of anticholinergic side effects).
* **Local Protocols:** Pediatric use should be strictly restricted to specialist prescription only. If used, dosing is weight-based (Mefenamic Acid 25 mg/kg/day in divided doses). **Do not use in children < 6 months due to risk of fatal respiratory depression/apnea associated with Dicyclomine.**
## Dose Adjustments
* **Renal Impairment:** Contraindicated or requires extreme caution in severe renal impairment (CrCl < 30 mL/min) due to Mefenamic Acid.
* **Hepatic Impairment:** Use with caution; monitor liver enzymes.
* **Elderly:** Use lowest effective dose. Increased risk of anticholinergic side effects (confusion, urinary retention, constipation, falls).
## Contraindications
* Hypersensitivity to Mefenamic Acid, Dicyclomine, or aspirin/other NSAIDs.
* Active peptic ulceration or inflammatory bowel disease (IBD).
* Severe renal or hepatic impairment.
* History of GI bleeding or perforation.
* Glaucoma (narrow-angle), obstructive uropathy, or myasthenia gravis (Dicyclomine content).
* Peri-operative pain management in the setting of coronary artery bypass graft (CABG) surgery.
## Adverse Effects
* **NSAID-related:** Epigastric distress, GI ulceration/bleeding, peripheral edema, hypertension.
* **Anticholinergic-related:** Dry mouth, blurred vision, tachycardia, urinary hesitancy, constipation, dizziness.
* **Serious:** Anaphylaxis, Stevens-Johnson syndrome, cardiovascular thrombotic events.
## Key Drug Interactions
* **Anticoagulants (Warfarin/Heparin):** Increased risk of bleeding.
* **Diuretics/ACE Inhibitors:** Reduced antihypertensive effect and increased risk of acute kidney injury.
* **Methotrexate:** Increased risk of toxicity due to decreased renal clearance.
* **CNS Depressants/Alcohol:** May exacerbate sedation.
## Monitoring
* Monitor for signs of GI bleeding (tarry stools, hematemesis).
* Assess blood pressure periodically during chronic or repeated use.
* Monitor renal function (BUN/SCr) in vulnerable patients.
* Monitor for anticholinergic toxicity (especially in the elderly).
## Clinical Pearls
* Take with food or milk to minimize gastric irritation.
* Advise patients to avoid tasks requiring mental alertness (driving/machinery operation) until individual response to Dicyclomine is known.
* Avoid concomitant use of other NSAIDs to prevent overdose or toxicity.
* Discontinue immediately if skin rash or evidence of GI ulceration occurs.
