# Meftal spas
## Overview
Meftal spas is a combination product containing mefenamic acid and dicyclomine hydrochloride. Mefenamic acid is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits prostaglandin synthesis. Dicyclomine is an anticholinergic and antispasmodic agent used to relieve smooth muscle spasms.
## Primary Indications
* Management of abdominal pain associated with smooth muscle spasms, particularly in conditions like irritable bowel syndrome (IBS) or dysmenorrhea.
## Adult Dosing
* **Typical dose:** 1 tablet (mefenamic acid 250 mg, dicyclomine HCl 20 mg) orally every 8 hours as needed.
* **Maximum dose:** Generally not to exceed 4 tablets per day. The duration of use should be limited to a few days.
## Pediatric Dosing
* **Children:** Safety and efficacy have not been established in pediatric patients. Use is generally not recommended.
## Dose Adjustments
* **Renal Impairment:** Use with caution. Mefenamic acid is renally excreted.
* **Hepatic Impairment:** Use with caution.
## Contraindications
* Hypersensitivity to mefenamic acid, dicyclomine, or other NSAIDs.
* Patients with inflammatory bowel disease.
* Obstructive uropathy or gastrointestinal obstruction.
* Severe renal or hepatic impairment.
* Myasthenia gravis.
* Uncontrolled asthma.
* Glaucoma.
* Lactation.
## Adverse Effects
* **Common:** Nausea, vomiting, diarrhea, constipation, abdominal pain, dizziness, drowsiness, dry mouth, blurred vision.
* **Serious:** Gastrointestinal bleeding, ulceration, perforation; renal failure; hepatic impairment; cardiovascular thrombotic events; anaphylaxis; exacerbation of glaucoma; urinary retention.
## Key Drug Interactions
* **Anticoagulants (e.g., warfarin):** Increased risk of bleeding.
* **Corticosteroids:** Increased risk of gastrointestinal ulceration and bleeding.
* **Other NSAIDs or Aspirin:** Increased risk of adverse effects, particularly gastrointestinal.
* **ACE inhibitors/ARBs:** Reduced antihypertensive effect, increased risk of renal impairment.
* **Diuretics:** Reduced diuretic effect, increased risk of renal impairment.
* **Anticholinergics:** Additive anticholinergic effects.
## Monitoring
* **Gastrointestinal symptoms:** Monitor for signs of bleeding or ulceration.
* **Renal function:** Especially in patients with pre-existing renal disease or those at risk.
* **Hepatic function:** Monitor liver enzymes if prolonged use is contemplated or if signs of hepatic dysfunction appear.
* **Ophthalmic evaluation:** Consider if blurred vision or other visual changes occur.
## Clinical Pearls
* Limit use to the shortest duration necessary for symptom control.
* Advise patients to take with food or milk to reduce gastrointestinal upset.
* Inform patients of potential side effects, especially GI bleeding, and to report any concerning symptoms immediately.
* Due to anticholinergic effects, caution patients about activities requiring mental alertness, such as operating machinery or driving.
