For support, over-the-counter options include magnesium, a B-vitamin complex, electrolytes or calcium-with-magnesium-and-vitamin-D formulas.

When to see a doctor

If any of these signs appear, consult a doctor — OTC treatment is not enough:

  • Severe persistent cramps
  • Associated muscle weakness
  • Cramps in the context of new medication (statins, diuretics)
  • Localized swelling, pain, redness (rule out DVT)
  • Severe chest or abdominal cramps

Common causes

Dehydration and fluid-electrolyte losses (exertion, diarrhea), magnesium/potassium/calcium deficiency, varicose vein disease, diabetes, hypothyroidism, medications (diuretics, statins), pregnancy, the elderly.

OTC treatment

Magnesium 300-400 mg in the evening — the most effective, especially for nocturnal cramps. Well-absorbed forms: bisglycinate, citrate.

Quinine — traditionally used, but withdrawn in many countries because of adverse effects; tonic water with quinine in small amounts is safe.

B complex, vitamin E — weaker effects, useful for prevention.

Electrolyte drinks — after exertion or heavy sweating.

Acute treatment of a cramp

  • Passive stretching of the muscle (for the calf: pull the tip of your foot toward you).
  • Local massage.
  • Applying heat (if it is chronic/tension-related) or cold (after exertion).
  • Slow walking if it occurs at night.

Prevention

Adequate hydration (at least 1.5-2 L per day), warming up and stretching before and after exertion, a diet rich in magnesium (nuts, seeds, green vegetables), potassium (bananas, potato), calcium.

Step by step

How to find a pharmacy fast for cramps

Open the interactive map and grant location permission — you'll immediately see pharmacies sorted by distance, each with its opening hours and a one-tap route in Google Maps. If it's night or a weekend, switch on the 24/7 filter to keep only the on-call ones. For cramps most of the listed remedies are over the counter, so you can walk in without a prescription, but check stock and prices on the comparator page first to avoid wasted trips.

If you have a preferred active ingredient (paracetamol, ibuprofen, etc.), search it in the comparator before you leave — you'll see which chain has it cheapest near you and whether it's in stock. For chronic prescriptions, save your favourite pharmacy in the app and turn on hours notifications — it saves unnecessary trips, especially when treatment for cramps runs over weeks.
