Claritin vs Sudafed
Introduction
For patients dealing with symptoms of allergies or colds, certain medications can help manage symptoms and improve overall well-being. Claritin and Sudafed are two such drugs that are often recommended for these conditions. Each affects different systems in the body, but both can provide relief for patients dealing with these common conditions. Claritin, also known as loratadine, is an antihistamine that blocks the action of histamine, a substance in the body that causes allergic symptoms. On the other hand, Sudafed, or pseudoephedrine, is a decongestant that shrinks blood vessels in the nasal passages, helping to reduce congestion and swelling. Both of these medications are available over-the-counter, but they have different uses depending on the symptoms a patient is experiencing.

What is Claritin?
Loratadine (the generic name for Claritin) was developed as a second-generation antihistamine, which marked a significant advancement over the first generation of antihistamines. Loratadine was first approved by the FDA in 1993. Unlike its predecessors, Claritin does not cross the blood-brain barrier effectively, hence it doesn't cause drowsiness—a common side effect associated with older antihistamines. It is prescribed to relieve symptoms related to allergic conditions like hay fever.
On the other hand, Pseudoephedrine (the generic variant of Sudafed) belongs to a class of medications called nasal decongestants. Sudafed is primarily used to alleviate congestion caused by colds and allergies but works differently from an antihistamine like Claritin because it shrinks swollen nasal mucous membranes; this helps clear nasal passages making breathing easier.
While both have their unique applications and advantages when dealing with allergy-related symptoms, they function distinctly different at a biological level—Claritin blocks histamine activity reducing allergy symptoms while Sudafed constricts blood vessels relieving congestion. As such, each has its own set of potential side effects that patients need to consider before use.
What conditions is Claritin approved to treat?
Claritin is approved for the treatment of various allergy-related symptoms:
- Seasonal allergic rhinitis, also known as hay fever
- Chronic idiopathic urticaria, commonly known as hives
- Other allergies that cause runny nose, sneezing, itchy or watery eyes
Sudafed on the other hand is used primarily to treat nasal and sinus congestion caused by allergies or common colds.
How does Claritin help with these illnesses?
Claritin aids in managing allergic reactions by inhibiting the effects of histamine, a compound that is released by cells in response to injury and in allergic and inflammatory reactions. It does this by acting as an antagonist at the H1 receptor site, preventing histamine from binding there which can cause symptoms such as runny nose, sneezing, itchy or watery eyes, itching of the nose or throat. Histamines are chemicals that act as messengers within our body involved in immune responses including allergies. Sudafed functions differently - it works primarily to relieve nasal congestion by causing vasoconstriction (narrowing) of blood vessels inside your nostrils reducing swelling and helping you breathe easier. Therefore, while both Claritin and Sudafed help manage symptoms associated with allergies or colds they do so via different mechanisms; one targeting histamines directly while another improving physical conditions leading to symptom relief.
What is Sudafed?
Sudafed is a brand name for pseudoephedrine, which is a sympathomimetic amine that acts as a decongestant. This means it works by narrowing the blood vessels to decrease congestion and swelling in the nasal passages. Pseudoephedrine was first approved by the FDA in 1951. As Sudafed does not act as an antihistamine like Claritin (loratadine), it doesn't block histamine receptors or prevent allergic responses but rather focuses on alleviating congestion symptoms associated with colds, allergies or sinus infections. Its lack of action on histamines means its side-effect profile also differs from those of antihistamines such as Claritin, particularly in that it might cause stimulation resulting in restlessness or insomnia instead of sedation (a common side effect of antihistamines). The effects on congestion can be beneficial for treating conditions where fluid build-up is present, especially when patients do not respond well to "typical" over-the-counter allergy medications such as Claritin.
What conditions is Sudafed approved to treat?
Sudafed is authorized for use in the treatment of:
- Nasal congestion due to common cold, hay fever or other respiratory allergies
- Sinus congestion and pressure
It's important to remember that Sudafed works by narrowing blood vessels in the nasal passages, which can ultimately help reduce swelling and congestion. However, it doesn't treat the underlying cause of these symptoms or shorten their duration.
How does Sudafed help with these illnesses?
Pseudoephedrine, the active ingredient in Sudafed, is a sympathomimetic drug that mimics the action of epinephrine (adrenaline), a hormone and neurotransmitter. It plays roles in many processes within the body such as increasing heart rate, blood pressure, and bronchial relaxation. This makes it particularly effective in reducing nasal congestion associated with colds or allergies by shrinking swollen nasal passages for easier breathing. However, due to its stimulant effects on the cardiovascular system and potential for misuse, Sudafed sales are regulated in many areas. Unlike Claritin which primarily acts as an antihistamine to reduce symptoms like runny nose and itching without tackling congestion directly; Sudafed's decongestant role can often make it more suitable for those dealing with blocked noses or sinuses. Nonetheless, individuals with certain health conditions including uncontrolled high blood pressure or heart disease should consult their healthcare provider before using medications like Sudafed.
How effective are both Claritin and Sudafed?
Both loratadine (Claritin) and pseudoephedrine (Sudafed) have established histories of success in treating symptoms related to allergies and the common cold. They were initially approved by the FDA within a decade of each other, with Sudafed receiving approval first. As they act on different mechanisms, they may be used under different circumstances or even together for comprehensive symptom relief.
Loratadine is an antihistamine that is effective in relieving allergy symptoms such as sneezing, itchy or watery eyes, runny nose, and itchiness of the nose or throat. Pseudoephedrine is a decongestant that works by narrowing blood vessels to reduce swelling and congestion in the nasal passages.
In terms of safety profiles, both drugs are generally well-tolerated but can cause side effects. Loratadine's most commonly reported side effect is drowsiness though it’s considered non-sedating; other potential side effects include headache and dry mouth. On the other hand, pseudoephedrine can potentially cause restlessness or sleep issues due to its stimulant properties; less frequently it might also lead to increased heart rate or blood pressure.
A 2001 study compared the efficacy of loratadine alone versus a combination pill containing both loratadine and pseudoephedrine for treating seasonal allergic rhinitis[1]. The results showed that both treatments reduced overall allergy symptom scores significantly more than placebo did – highlighting their individual effectiveness – while patients taking combination therapy saw additional improvement particularly with regard to nasal congestion.
As stand-alone medications: Claritin stands out as one of today's most widely-used antihistamines worldwide because it offers non-drowsy relief from several common allergy symptoms throughout an entire day with just one dose[2], whereas Sudafed remains popular especially among those suffering from sinus-related problems owing partly to its ability at providing quick-acting relief from nasal/ sinus congestion[3].

At what dose is Claritin typically prescribed?
Oral dosages of Claritin range from 10–20 mg/day, although research suggests that a single daily dose of 10 mg is sufficient for relieving symptoms of allergic rhinitis and hives in most adults and children over the age of six. For children aged two to five, the recommended starting dosage is 5mg once per day. In both populations, if relief isn't achieved or symptoms persist, consultation with a healthcare provider is advised before adjusting dosage. The maximum daily dose that should not be exceeded under any circumstances is 20 mg.
On the other hand, Sudafed doses vary depending on which formulation you are using (Sudafed 12 hour or Sudafed 24 hour). For Sudafed 12-hour it's one tablet every twelve hours and for Sudafed-24 hour it's one tablet every twenty-four hours for adults and adolescents older than twelve years old. Children younger than twelve should not take this medication without consulting with their healthcare provider first.
At what dose is Sudafed typically prescribed?
Sudafed treatment typically begins at a dosage of 60 mg every four to six hours for immediate-release tablets. If extended-release tablets are prescribed, the starting dose is typically 120 mg every 12 hours, or possibly increased up to 240 mg taken once daily. The maximum permissible dose is 240mg/day, which may be reached if there's no response to lower doses within a reasonable timeframe. It's important not to exceed this maximum limit and equally vital that doses should be spaced appropriately throughout the day depending on the formulation used (either every four-to-six hours for immediate release, or twelve-hourly for extended release tablets).
What are the most common side effects for Claritin?
Common side effects of Claritin include:
- Headache
- Dry mouth
- Fatigue, sleepiness/drowsiness (somnolence)
- Nervousness
- Stomach discomfort or upset stomach
- Diarrhea
On the other hand, Sudafed may cause:
- Anxiety and restlessness
- Dizziness and headache
- Insomnia (difficulty in sleeping)
- Nausea and vomiting
-An increased heart rate or palpitations -Dry mouth
Both medications can potentially cause an allergic reaction which could lead to rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing. It's essential to consult with your healthcare provider if you experience any unusual symptoms after taking these medications.
Are there any potential serious side effects for Claritin?
While Claritin and Sudafed are both effective over-the-counter medications for treating allergy symptoms, it's important to be aware of potential side effects. Here is what you should look out for:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling of your face, lips, tongue, or throat
- Rapid heart rate or fluttering in your chest
- Dizziness or feeling like you might faint
- Problems with vision like blurriness or seeing halos around lights
- Severe restlessness or nervousness
- Increased blood pressure: severe headache, blurred vision, pounding in your neck or ears
For Sudafed specifically:
- Trouble sleeping (insomnia)
And for Claritin specifically:
- Feeling tired
If you experience any serious side effects while taking either medication – including those listed above – seek medical attention immediately. Be sure to consult a healthcare professional before starting these medications if you have any existing health conditions.
What are the most common side effects for Sudafed?
Sudafed, also known as pseudoephedrine, is an over-the-counter medication often used for relief of nasal and sinus congestion. However, it can come with a range of side effects including:
- Dry mouth or throat
- A feeling of nervousness or restlessness
- Dizziness and headache
- Sleep problems (insomnia)
- Nausea or stomach upset
- Increased heartbeat rate In some rare cases, Sudafed may cause ringing in the ears, blurred vision, increased urination and even skin rash. It is important to note that individuals should seek immediate medical attention if they experience chest pain or fast/pounding/irregular heartbeat while using Sudafed.
Are there any potential serious side effects for Sudafed?
While Sudafed is highly effective for relieving congestion, it's important to remain aware of potential side effects. These can include:
- Signs of an allergic reaction: hives; difficulty breathing; swelling in your face, lips, tongue or throat
- Fast or irregular heartbeats
- Severe dizziness and anxiety
- Easy bruising or bleeding, unusual weakness
- Dangerously high blood pressure (severe headache, blurred vision, buzzing in your ears)
- Increased restlessness and insomnia
If you experience any of these symptoms while using Sudafed, immediately stop its use and consult a healthcare professional.
Contraindications for Claritin and Sudafed?
Both Claritin and Sudafed, like most other allergy medications, can cause side effects in some people. If you notice symptoms such as difficulty breathing, hives or swelling of your face, lips, tongue or throat after taking these medicines, please seek immediate medical attention.
Neither Claritin nor Sudafed should be taken if you are using a monoamine oxidase inhibitor (MAOI) or have used one in the past two weeks. Always inform your healthcare provider about any medications you’re currently on; MAOIs will require approximately two weeks to clear completely from your system to prevent dangerous drug interactions with Claritin and Sudafed.
How much do Claritin and Sudafed cost?
For the brand name versions of these drugs:
- The price of 30 tablets of Claritin (10 mg) averages around $20, which works out to approximately $0.67/day.
- The cost for Sudafed (pseudoephedrine), specifically a box containing 24 tablets of Sudafed 12-Hour (120 mg), is about $8–$10, working out to roughly $0.33–$0.42 per day.
Thus, if you are taking a single dose every day, then Sudafed is less expensive than Claritin on a daily basis. However, please remember that cost should not be your primary consideration in determining which drug is right for you.
As with most medications, prices can significantly drop when it comes to their generic versions:
- Loratadine (the active ingredient in Claritin) typically costs between $7 and $15 for a pack of 30 tablets (10mg), making the cost per day as low as about $.23 up to $.50.
- Pseudoephedrine hydrochloride - the active ingredient in Sudafed - usually retails at around $5-$9 for a box containing 24 x120mg extended-release tablets; this means that your per-day treatment could range from approximately $.21 up to $.38 .
Popularity of Claritin and Sudafed
Loratadine, in generic form as well as brand names such as Claritin, was estimated to have been used by about 40 million people in the US in 2020. Loratadine accounted for just over 18% of antihistamine use in the US. As a second-generation antihistamine, it is less likely to cause drowsiness compared to first-generation options. The prevalence of loratadine has been generally increasing since its FDA approval in 1993.
Pseudoephedrine, including brand versions such as Sudafed, was used by approximately 25 million people in the USA in 2020. In the US market for decongestants, pseudoephedrine accounts for around 30%. Pseudoephedrine is an effective nasal decongestant but can cause side effects like restlessness and insomnia more frequently than non-stimulant options like loratadine (Claritin). The prevalence of pseudoephedrine has remained relatively steady over recent years despite regulatory restrictions due to potential misuse.
Conclusion
Both Claritin (loratadine) and Sudafed (pseudoephedrine) have long-standing records of usage in patients with allergies, nasal congestion, and similar symptoms. They are both backed by numerous clinical studies indicating that they are more effective than placebo treatments. These drugs act differently - Claritin is an antihistamine that reduces the natural chemical histamine in the body which can produce symptoms of sneezing, itching, watery eyes, and runny nose; while Sudafed works as a decongestant shrinking blood vessels in the nasal passages.
Claritin is often considered a first-line treatment for allergy symptoms due to its non-drowsy formula whereas Sudafed may be used as an addition when dealing with sinus pressure or severe congestion. Both medications are available over-the-counter although some forms of Sudafed require asking for it at the pharmacy counter due to regulations on its sale.
The side effect profile is somewhat different between these two medications – while both being generally well-tolerated, Sudafed has potential side effects including restlessness and difficulty sleeping. For both drugs, patients should seek medical help immediately if they notice any serious side effects such as irregular heartbeat or difficulty urinating.
