What is Acrivastine?

Acrivastine is a non-drowsy, second-generation antihistamine made to ease signs linked with allergies. It works by stopping a natural body chemical from causing symptoms such as sneezing, a runny nose, itchy eyes, and skin reactions. This medicine is widely used for treating allergic rhinitis, hay fever, and urticaria.

Acrivastine is known for its quick action and very low chance of making you sleepy, so patients can carry on with their regular activities. It comes in an oral tablet and is given when a non-drowsy option is needed. This trusted option helps improve life for those with allergies.

What is Acrivastine Used For?

Allergic Rhinitis Management: Acrivastine is used to ease signs of allergic rhinitis, such as sneezing and a blocked nose.
Hay Fever Relief: It reduces the irritation, runny nose, and itchy eyes that come with hay fever.
Urticaria Treatment: The medicine helps lessen hives and skin rashes, giving good relief from allergic skin reactions.
At 123Meds, we supply Acrivastine for the treatment of allergies only – if you are thinking about using Acrivastine for any other condition, we suggest you get further advice from your GP to see if it is the right treatment option.

How Acrivastine Works

Acrivastine works by blocking a natural substance called histamine, which is released when you have an allergy. By doing this, it cuts down on common signs like sneezing, itching, and watery eyes while keeping sleepiness to a minimum.

Mechanism of Action:

H1 Receptor Antagonism: Acrivastine attaches to histamine H1 receptors so that histamine cannot trigger an allergic response.
Blocking Inflammatory Chemicals: By stopping histamine, it also helps lower the release of other chemicals that add to allergy symptoms.
Rapid Symptom Relief: It is absorbed quickly, blocking receptors fast so that allergy signs ease without causing much drowsiness.

When is Allergy Confirmed, and Medication Needed?

Allergy is confirmed when a patient shows ongoing and clear signs such as sneezing, a blocked nose, itchy, watery eyes, and sometimes skin reactions.

Allergy tests, like skin prick and blood tests, may be done to find the exact allergens. When these signs seriously affect life or stop daily tasks, prescribers suggest prescribed medication to control the allergic reaction. A quick check-up helps choose the right treatment, ensuring safe and clear relief from troublesome signs. A fast visit to a GP always helps secure the best allergy treatment.

Physical causes of Allergy:

Environmental Allergen Exposure: Being around airborne particles like pollen, dust mites, mould, and pet dander can set off the immune system and cause allergic reactions.
Chemical Irritants: Coming into contact with chemicals in pollution and household cleaning products may upset the breathing system, leading to allergy signs.
Occupational Exposures: Regular contact with certain substances at work, such as latex or industrial chemicals, can start or make allergic reactions worse.

Psychological causes of Allergy:

Stress-Related Immune Changes: High stress levels can disturb immune function, increasing the body’s sensitivity to allergens.
Emotional Distress: Long-term anxiety or depression may boost inflammatory responses, making allergy signs stronger.

Symptoms of Allergy:

Sneezing: Many frequent, hard-to-control nose sneezes.
Itchy Eyes: Red, watery, irritated eyes.
Skin Rashes: Raised, red, itchy welts.
If these signs last for several weeks or more, it is very important to seek help from a medical practitioner.

GPs will check for allergy by looking at your full medical history and any exposure to allergens. Depending on the causes, treatment choices might include prescribed medication like Acrivastine to ease allergy signs. Depending on each person’s needs, extra treatments or changes to daily routines might also be advised. It is important to speak with a medical practitioner to create a treatment plan that suits your needs.

Can Acrivastine Be Purchased Over the Counter?

Yes, Acrivastine is available over the counter in the UK. It is frequently sold under brand names such as Benadryl Allergy Relief.

Although you do not require a prescription, it is wise to speak with a pharmacist, particularly if you have existing conditions or take other prescribed medication. Some forms may also contain pseudoephedrine, which comes with extra rules. Always follow the dosage instructions on the pack or given by a medical practitioner.

Alternative Medications

If Acrivastine is not right for you, several other antihistamines are available in the UK to help with allergy signs. These alternatives differ in how long they work, their side effect profiles, and whether they make you sleepy.

Loratadine: Loratadine is a non-drowsy antihistamine that you take once a day. It is fit for treating hay fever and skin allergies. Sold over the counter, it is well tolerated and causes little sedation, making it a favoured option for use during the day without affecting alertness.
Cetirizine: Cetirizine is another commonly used antihistamine for hay fever, hives, and eczema-related itching. It may sometimes cause slight drowsiness, but it usually works fast and offers 24-hour relief. It is often chosen for its balance of effectiveness and few side effects.
Chlorphenamine: Chlorphenamine is a first-generation antihistamine often used for more severe allergic reactions. It makes you more sleepy than newer antihistamines, which can be useful for relief at night. Available both over the counter and by prescription, it is helpful when allergies disturb sleep or when stronger control of symptoms is needed.

Consult your 123Meds prescriber to decide on the best treatment for your condition.

How to Take Acrivastine?

Timing: Take Acrivastine at regular intervals during the day to keep a steady effect.

Dosage: The usual dose for adults is one 8 mg tablet up to three times a day, although this may vary with how severe your symptoms are and on medical advice. Always follow the instructions on the pack or given by your prescriber. The tablets should be swallowed whole with water and not broken or crushed. Elderly patients or people with certain conditions may need a different dose, so always check with your GP for advice. Follow the instructions carefully and report any side effects.

With Food: Acrivastine can be taken with or without food. However, taking it with a light meal may help reduce any minor tummy upset. Food generally does not affect how the medicine is absorbed or its overall effect. Always follow the instructions provided with your medication.

Avoid Consumption: Avoid alcoholic drinks, grapefruit, or high-fat meals while taking Acrivastine, as they can affect how the medicine is absorbed and its overall performance. Certain foods might worsen side effects or reduce the medicine's effectiveness, so always check any dietary guidelines.

If you missed a dose of Acrivastine, take it as soon as you remember unless it is nearly time for your next dose; never take a double dose to catch up.

Acrivastine includes both active and inactive ingredients that work together to provide effective allergy relief.

Active Ingredient:

The active ingredient in Acrivastine is Acrivastine, a potent H1 receptor antagonist that relieves allergy symptoms such as sneezing, runny nose, and itchy eyes by preventing the effects of histamine.

Inactive Ingredients:

Inactive components such as lactose monohydrate, sodium starch glycolate, magnesium stearate, titanium dioxide (E171), and gelatin are added to form the tablet, keep the product stable, and help proper absorption. These ingredients may differ between manufacturers, so please check the pack or contact us if you need more details.

Acrivastine is usually well tolerated; however, like all prescribed medication, it can cause side effects in some people. While most side effects are mild and short-lived, it is important to note both common and less common reactions.

Common Side Effects:

Drowsiness: Some people may feel a bit sleepy after taking Acrivastine.
Dry Mouth: A lower production of saliva can cause a feeling of a dry mouth.
Headache: Some users report mild headaches.
Dizziness: A light-headed or unsteady feeling may occur.
Nausea: A few patients might experience slight nausea or discomfort in the stomach.
Fatigue: General tiredness or low energy can sometimes be felt.
Mild Sedation: Although Acrivastine is classed as non-drowsy, sensitive individuals may notice a slight calming effect.
Stomach Upset: Some users report minor tummy discomfort after use.

Less Common but Serious Side Effects:

Severe Allergic Reaction: In rare cases, a serious allergic reaction may happen, showing signs like swelling of the face, lips, or throat. Immediate treatment is required.
Respiratory Difficulties: Some patients might suddenly have trouble breathing and need urgent medical attention.
Cardiovascular Effects: Although unusual, irregular heartbeats or noticeable palpitations can occur and should be checked quickly.

If you experience serious or ongoing side effects such as marked breathing problems, severe allergic reactions, or clear heart symptoms, seek immediate help from your GP, NHS111, or A&E to avoid complications. Do not ignore unusual or worrisome signs, as fast care can prevent further issues.

Before starting treatment with Acrivastine, ensure you have told your prescriber about all pre-existing conditions. This helps them decide on the best treatment and dose for you.

Is acrivastine the same as Benadryl?
While acrivastine is a key ingredient in some Benadryl Allergy Relief products in the UK, it is not the same in every case as Benadryl. In the United States, Benadryl usually contains diphenhydramine, which makes the products different even though they both work as antihistamines.
What is the difference between acrivastine and cetirizine?
Both acrivastine and cetirizine are second-generation antihistamines, but they vary in how they are taken and how quickly they start to work. Acrivastine usually provides quicker relief of symptoms but may need to be taken several times a day, while cetirizine is normally taken once a day, gives a longer effect, and might have slightly different side effects.

What are the side effects of acrivastine?
Common side effects of acrivastine include feeling drowsy, having a dry mouth, headaches, and dizziness, with some people also feeling sick or experiencing a bit of stomach discomfort. It is rare for there to be serious allergic reactions or heart issues, as most users find the side effects mild or easy to handle.
Is acrivastine a sedative?
Although acrivastine is known as a non-drowsy antihistamine, it can cause a little drowsiness in some people. The way it is made helps to limit its effect on the brain, but individual reactions can vary, and a small number of users might feel slightly sleepy or tired.
How long does acrivastine take to work?
Acrivastine usually starts to relieve allergy symptoms within 15 to 30 minutes after it is taken by mouth. Its full effect is often seen within one to two hours, which makes it useful for quickly reducing symptoms like sneezing, itching, and a runny nose.
Is acrivastine better than loratadine?
Whether acrivastine is better than loratadine depends on each person and their treatment needs. Acrivastine may give relief quicker but needs to be taken more often, while loratadine is usually taken once a day and is well known for its mild side effects, making it more convenient for many people.
Does acrivastine cause tiredness?
Acrivastine is made to lower the chance of feeling sleepy, yet some people may still feel tired or a bit drowsy. These effects are usually mild and happen less often than with first-generation antihistamines, though individual reactions can differ.
What class of drug is acrivastine?
Acrivastine is a second-generation antihistamine that works by blocking H1 receptors. It is mainly used to ease allergy symptoms such as sneezing, a runny nose, and itchy eyes, with a lower risk of causing sleepiness compared to first-generation antihistamines.

Acrivastine is generally seen as safe when taken as instructed. Most people handle it well, experiencing only mild side effects like drowsiness, headaches, or a dry mouth. However, responses can differ, so it is best to speak to your medical practitioner if you have any concerns or notice any unwanted effects.
How many days in a row can you take acrivastine?
There is no strict limit on how many days in a row you can take acrivastine; it is often used as needed for sudden allergy symptoms. However, if symptoms continue or you need to use it for several days, it is advisable to talk to your medical practitioner for further advice.
Why am I tired all day after acrivastine?
Although acrivastine is made as a non-drowsy antihistamine, some people may still feel tired or lightly sedated. Personal sensitivity, the dose, or possible interactions with other substances might cause this tiredness, so discussing these effects with your medical practitioner is advised.
Can you take loratadine and acrivastine together?
Combining loratadine and acrivastine is generally not advised unless recommended by a healthcare professional. Using two antihistamines at the same time can increase the chance of side effects such as drowsiness, dry mouth, or other unwanted reactions, without giving much extra benefit.
What organ is acrivastine bad for?
Acrivastine is mostly cleared by the kidneys, so it should be used carefully by people with kidney problems. In severe kidney issues, the drug may not be cleared properly, raising the risk of side effects; therefore, guidance from a healthcare professional is needed.
Is it safe to take acrivastine allergy every day?
Acrivastine is usually safe for use when needed; however, taking it daily or for a long time should be discussed with your medical practitioner. Regular use might cover up underlying allergy issues and increase the risk of side effects, so it is best to get professional advice if symptoms persist.
Is it harmful to take acrivastine every night?
Taking acrivastine every night is not usually harmful in the short term but may lead to ongoing side effects such as constant drowsiness or fatigue. Long-term nightly use should be reviewed by your medical practitioner to make sure it is suitable for managing your allergy symptoms.
Does acrivastine help with anxiety?
Acrivastine is an antihistamine made to ease allergy symptoms and is not meant for treating anxiety. Although it might make some people feel a bit sleepy, its main use is not to treat anxiety and it should not be used instead of treatments that are recommended for anxiety.
What is an alternative to acrivastine?
Other second-generation antihistamines such as cetirizine, loratadine, and fexofenadine can be alternatives. They each help with allergy symptoms with different dosing schedules and may cause different side effects, so it is best to discuss these options with your healthcare provider.
