Serious Dymista Side Effects
Less than 1 in 10,000 people are known to experience a serious side effect, meaning most people will not experience them.
You should stop using Dymista and see your doctor as soon as possible if you do notice any of the following:
- Breathing problems – swallowing difficulties, gasping or choking for air
- Vision changes – blurred or increased pressure in your eye
- Damage and sores to the inside of your nose
Allergic Reaction to Dymista
Allergic reactions to Dymista are very rare.
Fluticasone, which is the active ingredient in Dymista nasal spray, can cause anaphylaxis in some people. In the unlikely event of a reaction, you should stop using Dymista immediately.
Call 999 and seek urgent medical attention if you experience:
- Difficulty breathing or swallowing
- Swelling of the face, mouth, lips, tongue or throat
- Sudden severe skin rash
Dymista and Weight Gain
Weight gain is not typically associated with Dymista nasal spray use.
The amount of fluticasone that enters the body is much lower than if it were taken orally or as an injection, which makes the likelihood of gaining weight very low.
However, there is a possibility that when used long-term or in higher doses, weight gain can occur. Long-term steroid use is associated with weight gain, but in this case unlikely, as it is administered as a nasal spray and not orally.
You should raise any concerns with your doctor about weight gain whilst using Dymista, so they can assess your usage.
Dymista and Anxiety
Dymista does not cause anxiety and is not listed as a known side effect.
The risk of experiencing mood or psychological changes is extremely low for most people. Some of the associated symptoms, such as dizziness, fast breathing, and increased heart rate, which can be very similar to anxiety symptoms, may affect a small number of patients.
Dymista for Treating Post-Nasal Drip
Dymista is effective in treating post-nasal drip caused by allergic rhinitis.
When allergies are present, mucus from your nose or sinuses can drip down the back of your throat. This can lead to your nose becoming blocked or runny, as well as leave you with a sore throat or cough.
Dymista contains both an antihistamine called Azelastine and the steroid Fluticasone. Azelastine helps with post-nasal drip by blocking histamine, the substance released in response to the allergen, and fluticasone helps to reduce inflammation and relieve congestion and irritation in the nasal passages that can contribute to post-nasal drip.
It is administered in the same way as treating hay fever symptoms, spraying once into each nostril morning and evening.
Summary
Dymista is a scientifically proven prescription nasal spray used to treat hay fever and allergy symptoms like sneezing, congestion, and a runny nose, combining azelastine (an antihistamine) and fluticasone (a corticosteroid).
While it is generally well-tolerated by most people, common side effects include nasal irritation, headaches, and dry mouth, which tend to be mild. Rarely, more serious side effects like allergic reactions, vision changes, or nasal irritation may occur.
It is important to follow safety guidelines and consult a doctor, especially for those who are pregnant or breastfeeding.
