Dehydration is very common after excessive alcohol consumption. Classic symptoms after a big night out can include a dry mouth, fatigue and a headache.

The good news is that you can reduce the effects of dehydration with a bit of pre-planning. It’s all about making sure that you replace the fluids you lose when you drink alcohol with the right liquids. Sometimes, water isn’t enough – an oral rehydration solution like Hydralyte can be more effective.

The suggested dose for Hydralyte after drinking alcohol is 400mL, sipped slowly

Why does alcohol dehydrate you?

Fact 1: Alcohol acts as a diuretic (a substance that increases urine output)

Fact 2: For every standard drink you consume (10 mg of pure alcohol) you are likely to urinate 100 mL more than you drink, leading to dehydration

Fact 3: Headache, dry mouth, fatigue and dizziness are symptoms of dehydration

Fact 4: Hydralyte is an effective treatment of dehydration

The National Health and Medical Research Council (Australia) recommends that adult men and women drink no more than 4 standard drinks on any one drinking occasion. Above that number is considered excess and can increase the risk of health-related injuries.

Excessive alcohol consumption involving 6 to 10 standard drinks could therefore lead to a net fluid loss of 600–1000 mL or more, and therefore dehydration.

How can Hydralyte help you feel better?

If you are planning on having a night out, you can take steps to minimise the likelihood of becoming dehydrated.

Drinking non-alcoholic beverages (e.g. water, juice) during and soon after alcohol consumption may reduce the level of dehydration.
However, drinking an oral rehydration solution (Hydralyte) offers some advantages:

  • Rehydration is likely to be more rapid
  • The retention of water and electrolytes is enhanced
  • A person may experience better sleep (and therefore feel better afterwards) due to the lessened urge to urinate during the night

How can you avoid becoming dehydrated?

  1. Try and get into the habit of having a glass of water for every second drink.
  2. Pack a sachet of Hydralyte in your pocket (gents) or a tube of tablets in your clutch (ladies) just as you would your keys or lipgloss – this will be a godsend when you see it throughout the drinking session… it’s also a great way to make friends if you have some to share!
  3. Always have a supply of Hydralyte in the fridge or leave some on the kitchen bench as a reminder when you get home.
  4. Hydrating with 200-400 mL of a product like Hydralyte before you go to bed, rather than when you wake up dehydrated, will go a long way to making the next day more bearable.

Suggested dose

Take 400 mL of Hydralyte (slowly) after the drinking occasion and prior to going to bed.

Before you take Hydralyte

  • Consult with your doctor or pharmacist if you intend to take Hydralyte for more than three days in a row
  • Hydralyte contains approx. 0.8mg/mL potassium – if you have kidney disease or are taking heart or blood pressure medicines, then consult your doctor before using Hydralyte
  • Hydralyte contains sodium – refer to packaging for content
