Allergic Reactions and Hypersensitivity
One of the most important reasons to avoid Flonase is a known allergy to fluticasone propionate or any other ingredient in the nasal spray. Allergic reactions can be severe and immediate, including swelling of the face, throat, or tongue, hives, and difficulty breathing. If you have a history of adverse reactions to similar medications, you should consult a doctor before use. If you experience any signs of a serious allergic reaction after using Flonase, seek emergency medical help immediately.
Signs of a serious allergic reaction
- Hives or rash
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing or wheezing
- Feeling lightheaded or faint
Infections and Weakened Immunity
As a corticosteroid, fluticasone can weaken the immune system, making it easier to get an infection or worsening an existing one. For this reason, caution is necessary in several scenarios:
- Existing infections: If you have an untreated bacterial, viral, fungal, or parasitic infection, using Flonase may worsen the condition. This includes herpes simplex virus infections in the eye.
- Fungal infections: The use of fluticasone can increase the risk of developing localized fungal infections, such as thrush (Candida) in the nose or mouth. Symptoms include white patches or sores in the mouth, throat, or nose. If this occurs, you should stop using the medication and contact your doctor for appropriate antifungal treatment.
- Exposure to illness: If you have not had chickenpox or measles, you should avoid people with these infections, as Flonase can weaken your body's ability to fight them off. The consequences can be serious or even fatal.
Recent Nasal Surgery or Trauma
Using Flonase is contraindicated for patients who have recently had nasal surgery, experienced nasal trauma, or have sores or ulcers inside their nose. Corticosteroids like fluticasone can impair wound healing. Spraying medication into a healing or compromised nasal passage can hinder the recovery process and increase the risk of complications such as:
- Delayed wound healing
- Nasal septal perforation, a hole in the cartilage separating the nostrils
- Nasal ulcers
- Frequent or severe nosebleeds
Patients should typically wait for at least one week, or as directed by their surgeon, before resuming use of any nasal steroid spray after surgery. This allows the nasal tissues to heal properly and minimizes the risk of complications.
Pre-existing Medical Conditions
Certain chronic health issues require careful consideration or complete avoidance of Flonase due to potential adverse effects.
- Glaucoma and cataracts: Prolonged use of corticosteroids, including nasal sprays, has been linked to an increased risk of developing glaucoma and cataracts. If you have a history of these conditions or have a family history of glaucoma, your eye pressure should be monitored regularly. Anyone who notices vision changes, blurred vision, eye pain, or sees halos around lights should contact their doctor.
- Liver disease: Fluticasone is metabolized in the liver. For individuals with severe liver disease, clearance of the medication may be slower, potentially increasing systemic exposure and the risk of side effects. Use with caution is advised.
- Diabetes: People with diabetes should use Flonase with caution, as systemic absorption of corticosteroids can affect blood sugar levels.
- Adrenal gland problems: Long-term use of high doses can increase the risk of adrenal gland suppression, which can cause symptoms like unusual tiredness, nausea, and dizziness.
- Osteoporosis: Extended corticosteroid use can decrease bone mineral density. Individuals with risk factors for osteoporosis should discuss this with their doctor.
Drug Interactions to Avoid
Flonase can interact with other medications, potentially increasing systemic side effects. Certain medications are potent inhibitors of a liver enzyme (CYP3A4) that metabolizes fluticasone. Co-administration should be done with caution or avoided.
- Ritonavir (HIV medication): Concomitant use with ritonavir can lead to significantly increased fluticasone levels, causing systemic corticosteroid effects like Cushing's syndrome and adrenal suppression. This combination is not recommended unless a doctor determines the benefits outweigh the risks.
- Ketoconazole (antifungal): Taking ketoconazole pills with Flonase can also increase fluticasone exposure. Caution is advised when co-administering.
Long-Term Use and Special Populations
While Flonase is generally safe for short-term use, certain groups need extra precautions.
- Children and adolescents: Flonase can affect growth rate in children and adolescents, and pediatric patients using it for extended periods may need regular monitoring by their doctor. The appropriate age for starting Flonase varies by product, so checking the specific product label is crucial.
- Pregnancy and breastfeeding: The safety of Flonase during pregnancy is not fully established. The amount of fluticasone transferred to breast milk is minimal, but risks versus benefits should be weighed by a healthcare provider.
- High-dose or long-term use: Using Flonase for more than the recommended time can increase the risk of serious side effects, including adrenal gland suppression, eye problems, and decreased bone density. Adults and older children should consult a doctor if they need to use it for more than 6 months per year.
Conclusion
While Flonase is a highly effective treatment for allergies, it is not appropriate for everyone. Individuals with specific pre-existing medical conditions, including recent nasal surgery, infections, glaucoma, or cataracts, should avoid or use the medication with extreme caution. Awareness of potential drug interactions with HIV and antifungal medications is also critical. Always read the label and consult with a healthcare professional to ensure Flonase is the right choice for your specific health needs.
