# 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
* Pain and spasms associated with irritable bowel syndrome (IBS).
* Abdominal cramps and pain.
## Adult Dosing
* **Mefenamic Acid:** 500 mg every 8 hours as needed. Maximum daily dose: 1500 mg.
* **Dicyclomine Hydrochloride:** 20 mg every 8 hours as needed. Maximum daily dose: 80 mg.
*Note: Specific dosing may vary based on local protocol and individual patient response.*
## Pediatric Dosing
Dosing for pediatric patients has not been established for this combination product. Mefenamic acid and dicyclomine may be dosed individually in pediatric patients under strict medical supervision, but this specific combination is not typically recommended.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Mefenamic acid is renally excreted.
* **Hepatic Impairment:** Use with caution. Mefenamic acid can affect liver function.
* **Elderly:** Increased risk of adverse effects, particularly GI bleeding and renal toxicity with mefenamic acid.
## Contraindications
* Hypersensitivity to mefenamic acid, dicyclomine, or other NSAIDs.
* History of asthma, urticaria, or allergic-type reactions after taking aspirin or other NSAIDs.
* Intestinal obstruction, paralytic ileus, pyloric or duodenal obstruction, achalasia, glaucoma, myasthenia gravis, severe renal or liver disease, severe ulcerative colitis.
* Infants less than 6 months of age (due to dicyclomine).
## Adverse Effects
* **Common (Mefenamic Acid):** Diarrhea, nausea, vomiting, abdominal pain, dyspepsia, constipation, headache, dizziness.
* **Common (Dicyclomine):** Dry mouth, blurred vision, urinary retention, constipation, drowsiness, confusion, dizziness.
* **Serious:** Gastrointestinal bleeding, ulceration, perforation; renal failure; hepatic failure; cardiovascular thrombotic events; Stevens-Johnson syndrome, toxic epidermal necrolysis.
## Key Drug Interactions
* **NSAIDs:** Increased risk of GI toxicity, renal toxicity.
* **Anticoagulants (e.g., Warfarin):** Increased risk of bleeding.
* **Corticosteroids:** Increased risk of GI bleeding.
* **Diuretics, ACE inhibitors, ARBs:** Increased risk of renal impairment.
* **Lithium, Methotrexate:** Increased serum levels and toxicity.
* **Other Anticholinergics:** Additive anticholinergic effects.
* **Amantadine, Quinidine, Tricyclic Antidepressants:** Additive anticholinergic effects.
## Monitoring
* Monitor for signs and symptoms of gastrointestinal bleeding (e.g., melena, hematemesis).
* Monitor renal and hepatic function, especially with prolonged use or in patients with pre-existing impairment.
* Monitor for anticholinergic adverse effects.
## Clinical Pearls
* Meftal Spas should be taken with food or milk to minimize gastrointestinal upset.
* Due to anticholinergic effects, caution is advised in hot environments, with activities requiring mental alertness, and in patients with prostatic hypertrophy or urinary retention.
* Avoid concurrent use with other NSAIDs.
* Dicyclomine's use in infants is generally discouraged due to risk of respiratory depression.
