In short: Dehydration occurs when the body loses more water and electrolytes than it takes in — over 2% of body weight — often due to exertion in heat, diarrhoea or vomiting, with children and the elderly being the most vulnerable. Mild rebalancing is usually done with oral rehydration salts, electrolyte drinks or diosmectite, whose prices you can compare on HartaFarmacii across Dr. Max, Tei, Catena and HelpNet, with values updated daily. This information is for guidance only and does not replace a medical consultation; see a doctor if confusion, low blood pressure or very infrequent urination appear.

When to see a doctor

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

  • Severe dehydration (confusion, hypotension, oliguria)
  • Inability to rehydrate orally (continuous vomiting)
  • Children under 2 years with moderate-to-severe signs
  • Elderly people with cognitive changes
  • Diabetes with very high blood glucose

Degrees of dehydration

Mild (2-5%): thirst, dry mouth, dark yellow urine.

Moderate (5-10%): intense thirst, fatigue, headache, dizziness, scant and dark urine, skin with a slow skin fold, tachycardia.

Severe (over 10%): hypotension, thready pulse, confusion, oliguria/anuria, sunken eyes, mottled skin — a medical emergency.

OTC treatment

Oral rehydration salts (ORS):

  • GES 45, Humana Elektrolyt, Hidrasec.
  • Drink in small, frequent sips.
  • Adult: 200-400 ml after each stool/vomit.
  • Child: 10 ml/kg after each loose stool.

Water, clear soup, weak tea — for mild dehydration.

Isotonic drinks — for athletes; not ideal for diarrhea (osmolarity).

Natural coconut water — a natural alternative rich in potassium.

Signs that you are drinking enough

  • Light-colored urine (pale straw yellow).
  • 6-8 urinations/day with normal volume.
  • You do not feel frequent thirst.
  • Skin with normal turgor.

Special losses

With persistent diarrhea/vomiting, in young children, in the elderly, in endurance athletes — increased need. With intense exertion — weigh yourself before and after, and compensate for 1.5x the losses.

Step by step

How to find a pharmacy fast for dehydration

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 dehydration 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 dehydration runs over weeks.

Frequently asked

What else do you want to know?

How much water should I drink per day?
1.5-2 L under normal conditions. +500 ml/h during exertion. +500-1000 ml in hot weather. More while breastfeeding, with fever, or with diarrhea.
Plain water or electrolytes?
Under 1h of exertion — water. Over 1h or with diarrhea/vomiting — electrolytes (ORS). For severe dehydration — a medical emergency requiring an IV drip.
How do I check for dehydration in a child?
Urine (a dry diaper for over 6-8h = a warning sign), dry mouth, sunken eyes, crying without tears, a persistent skin fold, apathy. At any suspicion — see a pediatrician.
Do tea or coffee cause dehydration?
Coffee in moderate amounts does not cause significant dehydration (the diuretic effect is compensated for). Alcohol, on the other hand, clearly causes dehydration.
