How Does Sinarest Work?
As discussed, Sinarest is a combination medication. It is a combination of three separate drugs, namely:
- Acetaminophen, which works to relieve pain and reduce fever (1).
- Chlorpheniramine, which is an antihistamine that helps reduce allergies (2).
- Pseudoephedrine, which works as a decongestant and treats a stuffy nose (3).
The combined effect of these three drugs makes Sinarest an ideal treatment for cold and flu symptoms. We will now look at how Sinarest treats those symptoms.
How Can Sinarest Help You?
1. Treats A Runny Nose
The chlorpheniramine in Sinarest bags the credit here. It suppresses histamine production in your body (2). Histamine is a compound released in the body during allergy symptoms, including a runny nose.
2. Fights Throat Infection
The acetaminophen in Sinarest can help relieve pain, including that associated with a throat infection. A report by The College of Family Physicians of Canada recommends acetaminophen to treat sore throat caused by a virus (4).
Acetaminophen is a paracetamol, and studies show that it can reduce the pain of an acute sore throat (5). In a study, paracetamol had significantly reduced pain within 15 minutes to 6 hours post-intake.
Acetaminophen is registered as a trustworthy drug that treats sore throat and related infections (6).
In a Brazilian study, a fixed dose of paracetamol, chlorpheniramine, and a nasal decongestant (like pseudoephedrine in Sinarest) was found to treat flu-like symptoms – including an infected throat (7).
3. Treats Sinusitis
Both acetaminophen and pseudoephedrine in Sinarest can aid sinusitis relief – more so with the daytime sinusitis that most people deal with. While acetaminophen has been found to relieve the pain associated with sinusitis, pseudoephedrine acts as a nasal decongestant (8).
In a New Jersey study, the combination of acetaminophen and pseudoephedrine was found to be effective in treating symptoms related to the paranasal sinuses (9).
4. Treats Ear Congestion
The acetaminophen in Sinarest can cure the pain associated with ear congestion (1). Ear congestion or even ear infection can often lead to fever, especially in children. Studies show that acetaminophen can help in dealing with this problem (10). The drug can reduce pain and lower fever – both possible symptoms of severe ear congestion and infection.
The pseudoephedrine in Sinarest, being a decongestant, can help treat ear congestion as well (11).
5. Treats Watery Eyes
Sinarest is an antihistamine. It suppresses histamine production that happens during allergies. This is one reason it can treat watery eyes – a condition common during allergic reactions.
The chlorpheniramine in Sinarest can also help relieve watery eyes (12). It helps control the symptoms of cold and allergies. It is one of the compounds in Sinarest that render it its antihistamine properties.
Sinarest may also help treat cough and body pains – symptoms often associated with fever and infection. But there is limited research on this.
You saw how Sinarest, a combination drug, can help you in various ways. Well, that is one side of the story. Like any drug, Sinarest too has its share of side effects.
