# Meftal-Spas
## Overview
Meftal-Spas is a combination medication containing **Mefenamic Acid** (250 mg), a non-steroidal anti-inflammatory drug (NSAID), and **Dicyclomine Hydrochloride** (10 mg), an antispasmodic/anticholinergic agent. It acts via prostaglandin inhibition and direct smooth muscle relaxation.
## Primary Indications
* Primary dysmenorrhea (menstrual cramps).
* Abdominal pain/cramping due to smooth muscle spasms.
## Adult Dosing
* **Standard dose:** 1 tablet (250 mg/10 mg) three to four times daily.
* **Maximum dose:** Do not exceed 4 tablets (1000 mg Mefenamic Acid) per 24 hours.
* **Duration:** Limit use to the shortest duration necessary, typically not exceeding 3 days for menstrual pain. Take with food to minimize GI irritation.
## Pediatric Dosing
* **Safety and efficacy are not established** for pediatric populations. Use is generally discouraged in children due to the Mefenamic Acid component and potential anticholinergic side effects of Dicyclomine. Consult local pediatric protocols or a specialist before use.
## Dose Adjustments
* **Renal Impairment:** Contraindicated in patients with moderate to severe renal impairment. Use with extreme caution in mild impairment; monitor serum creatinine.
* **Hepatic Impairment:** Avoid or use with extreme caution; Mefenamic acid is hepatically metabolized.
## Contraindications
* Hypersensitivity to Mefenamic acid, Dicyclomine, or other NSAIDs (including aspirin-sensitive asthma).
* Active peptic ulceration or inflammatory bowel disease.
* History of GI bleeding or perforation.
* Severe renal or hepatic failure.
* Conditions where anticholinergics are contraindicated: Glaucoma, obstructive uropathy, intestinal atony, myasthenia gravis, or unstable cardiovascular status in acute hemorrhage.
## Adverse Effects
* **Mefenamic Acid:** Nausea, abdominal pain, diarrhea, GI bleeding/ulceration, skin rash, edema.
* **Dicyclomine:** Dry mouth, blurred vision, dizziness, drowsiness, tachycardia, urinary retention, and constipation.
## Key Drug Interactions
* **Anticoagulants (e.g., Warfarin):** Increased risk of bleeding.
* **Other NSAIDs/Corticosteroids:** Increased risk of GI toxicity.
* **Antihistamines/Tricyclic Antidepressants:** May potentiate anticholinergic effects (dry mouth, urinary retention).
* **Antihypertensives/Diuretics:** NSAIDs may decrease the efficacy of ACE inhibitors, ARBs, and diuretics.
## Monitoring
* Monitor for signs of GI bleed (tarry stools, epigastric pain).
* Assess for renal function (BUN/Creatinine) during prolonged use.
* Observe for anticholinergic toxicity in the elderly (mental status changes/confusion).
## Clinical Pearls
* **Anticholinergic caution:** Dicyclomine can cause significant cognitive impairment in the elderly (Beers Criteria). Use with extreme caution in patients >65.
* **NSAID Risk:** Like all NSAIDs, it carries a potential increased risk of cardiovascular thrombotic events.
* **Not for chronic pain:** This formulation is intended for short-term symptomatic relief only.
