# Meftal spas
## Overview
Meftal spas is a combination product containing **mefenamic acid**, a nonsteroidal anti-inflammatory drug (NSAID), and **dicyclomine hydrochloride**, an anticholinergic antispasmodic.
## Primary Indications
* Symptomatic relief of mild to moderate pain associated with smooth muscle spasms, particularly in gynecological conditions and gastrointestinal disorders.
## Adult Dosing
* **Mefenamic Acid:** Typically 500 mg every 8 hours as needed for pain. Maximum daily dose: 1500 mg.
* **Dicyclomine Hydrochloride:** Typically 10 mg every 8 hours as needed for spasms. Maximum daily dose: 40 mg.
* The specific dosing regimen for Meftal spas will depend on the formulation and intended use, and may differ from individual component dosing. Always refer to the product labeling or local protocol.
## Pediatric Dosing
* Data on the use of Meftal spas specifically in pediatric populations is limited. Dosing of individual components in children is available but extrapolation to the combination product requires caution and professional judgment.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Mefenamic acid is renally eliminated. Dosage reduction may be necessary.
* **Hepatic Impairment:** Use with caution. Mefenamic acid can affect liver function.
* **Elderly:** Increased risk of adverse effects, particularly gastrointestinal bleeding, renal events, and cardiovascular events. Use with caution and consider lower doses.
## Contraindications
* Hypersensitivity to mefenamic acid, dicyclomine, or other NSAIDs/anticholinergics.
* Patients with active gastrointestinal ulceration or inflammation.
* Patients with a history of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs.
* Severe renal or hepatic impairment.
* Glaucoma.
* Myasthenia gravis.
* Obstructive uropathy or gastrointestinal obstruction.
* Unstable heart failure.
## Adverse Effects
* **Mefenamic Acid:** Gastrointestinal upset (nausea, vomiting, diarrhea, abdominal pain), GI bleeding, peptic ulceration, renal toxicity, hypersensitivity reactions, headache, dizziness.
* **Dicyclomine Hydrochloride:** Anticholinergic effects (dry mouth, blurred vision, urinary retention, constipation, drowsiness, confusion), tachycardia.
* Combination may increase the risk of certain adverse effects.
## Key Drug Interactions
* **Mefenamic Acid:**
* Anticoagulants (e.g., warfarin): Increased risk of bleeding.
* Corticosteroids: Increased risk of GI ulceration and bleeding.
* Diuretics and antihypertensives: May reduce efficacy and increase risk of renal toxicity.
* Lithium: Increased lithium levels.
* Other NSAIDs/Aspirin: Increased risk of GI adverse effects.
* **Dicyclomine Hydrochloride:**
* Amantadine, other anticholinergics: Additive anticholinergic effects.
* Antacids: May decrease absorption of dicyclomine.
* MAO inhibitors: May potentiate anticholinergic effects.
* Opioid analgesics: Increased risk of severe constipation.
## Monitoring
* Monitor for signs and symptoms of GI bleeding (e.g., melena, hematemesis).
* Monitor renal and hepatic function, especially with prolonged use or in susceptible patients.
* Assess for efficacy in pain and spasm relief.
* Monitor for anticholinergic side effects.
## Clinical Pearls
* Meftal spas should be taken with food or milk to minimize gastrointestinal upset.
* Limit duration of use to the shortest effective period to reduce risks associated with NSAIDs.
* Caution patients about operating machinery or driving due to potential drowsiness and blurred vision from dicyclomine.
* The combination addresses both inflammatory pain and smooth muscle spasm, potentially offering broader symptomatic relief.
