Meftal-Spas for Period Pain: Complete Guide for Indian Women

MMeftal-Spas (Blue Cross, ₹40/strip of 10) contains Mefenamic Acid 250mg + Dicyclomine 10mg. Mefenamic acid is an NSAID that blocks uterine prostaglandins (which cause cramps). Dicyclomine is an antispasmodic - relaxes smooth muscle in uterus and intestine. Combination specifically targets menstrual cramps better than plain painkillers. Other brands: Meftal Forte (500 + 10), Spasmotab, Spasmocip, Meftagesic-DS. Used for: primary dysmenorrhea (period cramps), abdominal colic, IBS cramping, minor uterine pain. Prescription-only drug, though many chemists in India dispense without asking.

Best timing: Start 1 tablet 1 day BEFORE expected period, then 3 times daily during cramp days (day 1-2). This preemptive dosing reduces prostaglandin build-up better than waiting for pain. If you didn't start early: 1 tablet every 6-8 hours when cramps hit. Max: 3 tablets / 24 hours. Take with food - reduces stomach irritation. Don't take empty stomach. Continue at most 3-5 days of your period. Don't use prophylactically through the whole month. Between periods, don't take Meftal-Spas for random pain; use plain paracetamol.

Primary dysmenorrhea: Cramps from first few days of period in otherwise healthy uterus (no fibroids, endometriosis, PID). Meftal-Spas works well for 70-80% of women. Mild-to-moderate cramps: Reduces pain by 60-70%. Combined with heat pack, hydration, rest. Doesn't work well for: Severe endometriosis pain, adenomyosis, large fibroids, chronic pelvic pain syndrome. If Meftal-Spas barely helps OR you need more than 3 tablets daily for cramps - see gynae for ultrasound. Severe pain monthly is not 'normal' - it's a signal.

Common: Drowsiness (from dicyclomine - don't drive if it makes you groggy), dry mouth, stomach upset, nausea, mild heartburn, dizziness. Bowel changes: constipation or occasionally diarrhea (less common). Rare: Severe rash, breathing difficulty (allergic reaction), blurred vision (dicyclomine effect), urinary retention in susceptible women. Long-term use: Mefenamic acid = NSAID; 5+ days/month × many months = stomach ulcer, kidney damage, BP rise risk. Signs of bleeding ulcer: black tarry stools, coffee-ground vomit, sudden severe abdominal pain. Stop and ER immediately.

Absolute contraindications: Previous allergy to mefenamic acid / dicyclomine. Active peptic ulcer. Severe kidney disease. Severe liver disease. Inflammatory bowel disease (IBD - Crohn's, UC). Heart failure. Narrow-angle glaucoma (dicyclomine issue). Myasthenia gravis. Urinary retention. Pregnancy - especially third trimester (NSAID harms fetal heart). Breastfeeding - small amounts in milk; occasional use OK; regular use avoid. Elderly on multiple meds (BP, diabetes, heart): caution; may prefer plain paracetamol + buscopan. Young teens first period: start with paracetamol, escalate only if needed.

Warfarin: Mefenamic acid increases bleeding - avoid combination. Other NSAIDs (Combiflam, Brufen, Voveran): Don't stack - additive stomach/kidney damage. ACE inhibitors (Ramipril), ARBs (Telmisartan): NSAID can reduce BP-lowering effect and stress kidneys. Diuretics (Furosemide): Kidney stress when combined. Lithium: Levels rise, toxicity risk. Methotrexate: Toxicity risk. Steroids (Wysolone): Stomach ulcer multiplies - add PPI. Alcohol: Stomach lining damage; avoid. Antacids (Gelusil): Slightly reduce absorption; space 2 hours. Oral contraceptives: No major interaction.

Plain paracetamol 650mg (Dolo) + heat bag + hydration: Mild cramps, first try. Ibuprofen 400mg (Brufen): More effective than paracetamol for cramps alone - similar stomach risk. Drotin-M (drotaverine + mefenamic): Alternative antispasmodic. Hormonal OCP (Yasmin, Diane-35, Krimson 35): Life-changing for severe monthly dysmenorrhea - shrinks uterine lining, reduces prostaglandins. Discuss with gynae. Tranexamic acid (Trapic MF - also has mefenamic): For heavy bleeding + cramps. Mirena IUD: For severe fibroid/adenomyosis pain + bleeding. Yoga, heat pack, magnesium supplementation, omega-3 fish oil - non-drug aids. Avoid daily Meftal-Spas beyond 5-day window per month.
