Although it’s classified as a non-drowsy hay fever medicine, there is a possibility that you could experience side effects, including drowsiness, which can be exacerbated by alcohol.
This article will help you to understand the side effects, potential risks, and how to use Loratadine safely when treating allergies.
The latest medical advice from the NHS states you should not drink alcohol with Loratadine. This is because some people can still feel sleepy after taking it. In fact, it is the most common side effect, with more than 1 in 100 people affected.
Loratadine is the same active ingredient found in the branded allergy medicine, Claritin. Although it is a second-generation histamine and classed as a non-drowsy medicine, drowsiness can be worsened when combined with alcohol because of its sedative effect.
Your ability to make decisions and alertness may be compromised if you mix alcohol with Loratadine. Drowsiness can put you at higher risk of accidents, as well as affect your day-to-day activities.
It may not work as effectively, too. This means that your symptoms could not improve or take far longer to do so after taking Loratadine.
Mixing alcohol with loratadine may pose long-term risks. The liver is key when it comes to processing both alcohol and loratadine. Chronic alcohol consumption can elevate the risk of liver damage and affect the metabolism of Loratadine, so it’s important to speak to your doctor or pharmacist if you have any liver issues.
The typical dosage is one tablet, taken daily. It’s important to always follow your doctors’ instructions to ensure you are using Loratadine safely.
You should be aware of possible interactions and warnings because this can affect whether Loratadine is suitable or not for you. The most up-to-date advice can be found on the patient information leaflet.
