L612 Pill: Uses, Effects, and Food Interactions
Everything You Need to Know About This Common Antihistamine Tablet
If you’ve ever come across a small, white, oval-shaped pill labeled L612, either online or in a medication pack, and wondered what it does, you’re not alone.

Many people have seen this pill without any clear information, leading to confusion and questions.
Fortunately, this detailed guide breaks down everything you need to know about L612 pills, from their medical uses and side effects to important food and drug interactions.
What Is the L612 Pill?
The pill marked L612 is a generic form of Loratadine, which is a second-generation non-drowsy antihistamine.
Loratadine is widely used to relieve common symptoms of allergies, such as sneezing, runny nose, itchy or watery eyes, and nasal congestion.
Allergies occur when the body releases chemicals known as histamines in response to allergens like pollen, dust, pet dander, or certain foods.
These histamines trigger allergy symptoms, and that’s where L612 comes in.
By blocking the effects of histamines, Loratadine helps to reduce allergy symptoms and bring relief to the sufferer.
It is most commonly taken once daily, and the effects usually last for 24 hours.
Brand and Manufacturer Information
L612 pills are typically 10mg doses of Loratadine and are sold under popular brand names like Claritin.
They are produced by Perrigo Company, a well-established pharmaceutical firm registered in Ireland with operational headquarters in the United States.
These pills are oval in shape, white in color, and have “L612” clearly imprinted on one side for identification.
Medical Uses of L612 Pills
Loratadine (L612) is used to manage a variety of allergic conditions, including:
- Seasonal Allergic Rhinitis (Hay Fever)
- Perennial Allergic Rhinitis (year-round allergy symptoms)
- Urticaria (chronic hives or skin rash)
- Physical Urticaria (rash caused by cold, heat, pressure, or sunlight)
- Mild respiratory allergies
It provides fast and long-lasting relief without causing the heavy sedation associated with older antihistamines.
Who Can Use L612 Pills?
Loratadine is a medication that can be used by both children and adults, but the dosage depends on age and health condition:
- Adults and children 6 years and older: 10mg (one pill) once daily
- Children under 6 years: 5mg (half pill) per day, preferably under medical supervision
- Pregnant and breastfeeding women: Generally considered safe (Pregnancy Category B), but should still consult a healthcare provider
- People with kidney or liver problems: Should only use L612 after consulting a doctor, as metabolism and clearance may be affected
Because L612 pills are sold over the counter, many people self-medicate.
However, it’s always a good idea to speak with a healthcare professional, especially if you’re taking other medications or managing chronic health issues.
Does L612 Make You Sleepy?
Loratadine is classified as a non-drowsy antihistamine, unlike first-generation antihistamines such as diphenhydramine (Benadryl).
However, some users have reported mild drowsiness, especially during the first few doses.
While these effects are uncommon, sensitivity may vary between individuals. Children may also experience fatigue, restlessness, or headaches.
Additionally, drinking alcohol or using other sedating drugs alongside Loratadine can increase the chance of drowsiness.
For this reason, it is best to avoid alcohol while taking L612 pills.

Therefore, always inform your healthcare provider if you’re taking any other medications.
How Food Affects the Effectiveness of L612 Pills
You may not realize it, but the foods you eat can influence how L612 pills work in your body.
Because the liver primarily processes Loratadine, your diet directly influences how effectively the drug works and how well it eases allergy symptoms.
Recommended Foods:
- Firstly, liver-supportive vegetables such as spinach, kale, and broccoli can help detoxify the liver
- Water-rich fruits like watermelon, cucumber, and oranges improve hydration and help flush out toxins
- Ginger or peppermint tea may soothe digestive discomfort and support immune health
- Lean protein sources such as fish, chicken, eggs, and legumes assist in tissue repair if inflammation is present
Foods and Substances to Avoid:
- Alcohol avoid drinking while taking L612, as it can strain the liver and increase drowsiness
- Greasy, high-fat foods can slow down the body’s ability to process the medication efficiently
- Excessive caffeine from coffee or energy drinks might intensify anxiety or fatigue when combined with antihistamines
In addition, it’s a good practice to take the pill with a light meal or snack, rather than on an empty stomach, to avoid any mild digestive discomfort or nausea.
