What medicine helps allergies go away?

Allergies are a common condition that affects millions of people worldwide. They occur when the immune system overreacts to a substance that is normally harmless, such as pollen, dust, or certain foods. This can lead to a range of symptoms, including sneezing, runny nose, itchy eyes, and skin rashes. While there is no cure for allergies, there are several medicines that can help alleviate symptoms and make allergies go away.


Antihistamines are the most commonly used medicine for allergies. They work by blocking the effects of histamine, a chemical released by the immune system in response to an allergen. Histamine is responsible for causing the symptoms of allergies, so by blocking its effects, antihistamines can help reduce symptoms such as sneezing, itching, and runny nose.

There are two types of antihistamines: first-generation and second-generation. First-generation antihistamines, such as diphenhydramine and chlorpheniramine, are more likely to cause drowsiness and are often used to treat allergies at night. Second-generation antihistamines, such as loratadine and cetirizine, are less likely to cause drowsiness and are suitable for daytime use.

Nasal Sprays

Nasal sprays are another common medicine used to treat allergies. They work by delivering a small amount of medication directly into the nasal passages, where allergens often enter the body. Nasal sprays can help relieve symptoms such as congestion, runny nose, and sneezing.

There are two types of nasal sprays: corticosteroid and antihistamine. Corticosteroid nasal sprays, such as fluticasone and budesonide, work by reducing inflammation in the nasal passages, which can help alleviate symptoms. Antihistamine nasal sprays, such as azelastine and olopatadine, work by blocking the effects of histamine in the nasal passages.


Decongestants are another type of medicine that can help with allergies. They work by shrinking the blood vessels in the nasal passages, which can help reduce congestion and make it easier to breathe. Decongestants are available in both oral and nasal spray forms.

Oral decongestants, such as pseudoephedrine and phenylephrine, are taken by mouth and can provide relief for several hours. However, they can also cause side effects such as increased heart rate and blood pressure, so they should be used with caution.

Nasal decongestants, such as oxymetazoline and phenylephrine, are applied directly into the nose and can provide quick relief for congestion. However, they should not be used for more than a few days, as they can cause rebound congestion and make symptoms worse.


For people with severe allergies that do not respond to other treatments, immunotherapy may be an option. This involves exposing the body to small amounts of the allergen over time, which can help the immune system become less sensitive to it. Immunotherapy can be administered through injections or sublingual tablets.

It is important to note that immunotherapy is a long-term treatment and may take several months to see results. It is also not suitable for everyone and should only be done under the supervision of a healthcare professional.

Other Treatments

In addition to medicines, there are other treatments that can help alleviate allergies. These include:

– Allergy shots: Similar to immunotherapy, allergy shots involve injecting small amounts of the allergen into the body to help build immunity.

– Eye drops: For people with allergies that mainly affect the eyes, antihistamine eye drops can provide relief from symptoms such as itching and redness.

– Topical creams: For skin allergies, topical creams containing corticosteroids or antihistamines can help reduce itching and inflammation.

– Neti pots: Neti pots are small devices used to flush out the nasal passages with a saline solution, which can help relieve congestion and clear out allergens.

It is important to consult with a healthcare professional before starting any new medicine or treatment for allergies. They can help determine the best course of treatment based on the type and severity of allergies.

In conclusion, while there is no cure for allergies, there are several medicines that can help alleviate symptoms and make allergies go away. Antihistamines, nasal sprays, decongestants, and immunotherapy are all effective treatments for allergies and can provide relief for a range of symptoms. It is important to work with a healthcare professional to find the best treatment plan for individual needs.
