What are Kalms One-A-Night tablets?

Kalms One-A-Night tablets are a herbal remedy for sleepless nights or temporary insomnia. If you’re struggling to drop off to sleep at night or find yourself waking up in the night so you can’t get some quality sleep, this product may help you to fall asleep and stay asleep. Kalms One-A-Night uses valerian root, a herbal remedy traditionally used to relieve insomnia and help you get your 8 hours of sleep. If you prefer natural remedies to sleeping pills, this could be the ideal choice for you.

What is insomnia?

Insomnia is the medical term for those nights when you can’t fall asleep or find yourself waking up in the night. Short-term or temporary insomnia is very common, most people experience it at some point in their lives, and lots of different things can cause it. For example, you may struggle to fall asleep if your mind is preoccupied with worries about work, stress over a looming exam, or if you suffer from mental health conditions such as anxiety or depression. You could also find yourself lying awake counting sheep if you’re jet lagged or work a shift pattern that disturbs your body’s natural rhythm. You can even find yourself suffering from insomnia for a reason as simple as an uncomfortable bed, your room being too cold or too hot, or your neighbours making a lot of noise. In these cases, short term sleeplessness usually isn’t anything to worry about, and it will often get better over time.

How will Kalms One-A-Night help to ease my insomnia?

Each Kalms One-A-Night tablet contains 385mg of an active ingredient called valerian root extract. Valerian root is a natural ingredient which is traditionally used to help you fall asleep, and it’s a popular ingredient in herbal sleep remedies. It’s thought to ease your short-term insomnia by making you feel drowsy, helping you to drop off for a good night’s sleep.

Can I take herbal sleeping tablets when I’m pregnant or breastfeeding?

Kalms One-A-Night tablets are not recommended for people who are pregnant or breastfeeding. If you’re struggling with insomnia during your pregnancy you should ask your doctor or pharmacist for advice. They will be able to recommend lifestyle changes that could help you to get some sleep and possibly suggest a suitable sleep aid if it’s absolutely necessary.

Can I take valerian root tablets if I’m taking other medications?

If you’re taking any other medication, including other herbal remedies or medications you obtained without a prescription, you should speak to your doctor or pharmacist before taking Kalms One-A-Night valerian root tablets. This especially applies if you are already taking:

  • Other medicines to help you sleep. This product should not be used with other sleeping medications
  • Medicines to make you drowsy

Can I drive after taking these tablets?

Kalms One-A-Night tablets are a herbal sleep aid, so they’re designed to make you feel sleepy or drowsy. For this reason, you shouldn’t attempt to drive or use any tools or machinery after taking these tablets. If you do need to drive, wait until your drowsiness or any other symptoms which could affect your ability to drive have passed and you’re sure that you can do so safely.

Can I drink alcohol while I’m taking herbal sleeping tablets?

Alcohol can make the sedative effect of Kalms tablets worse. You shouldn’t drink alcohol while taking these tablets to avoid the increase in this symptom.
