Meloxicam - Can you take meloxicam for swollen, inflamed, nasal passages?

Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID). It works by reducing hormones that cause pain, fever, and inflammation in the body.

Meloxicam is used to relieve pain, tenderness, swelling, and stiffness caused by osteoarthritis (arthritis caused by a breakdown of the lining of the joints) and rheumatoid arthritis (arthritis caused by swelling of the lining of the joints).

Meloxicam is also used to relieve the pain, tenderness, swelling, and stiffness caused by juvenile rheumatoid arthritis (a type of arthritis that affects children) in children 2 years of age and older.

Now, I believe that by the symptoms you describe you may have the following and Meloxicam will not help you:

Chronic sinusitis causes the spaces inside the nose and head, called sinuses, to become inflamed and swollen. The condition lasts 12 weeks or longer, even with treatment.

This common condition keeps mucus from draining. It makes the nose stuffy. Breathing through the nose might be hard. The area around the eyes might feel swollen or tender.

Infection, growths in the sinuses, called nasal polyps, and swelling of the lining of the sinuses might all be part of chronic sinusitis. Chronic sinusitis is also called chronic rhinosinusitis. The condition affects adults and children.

Most cases of acute sinusitis get better on their own. Self-care is usually all that's needed to ease symptoms.

Treatments to ease symptoms
The following might help ease sinusitis symptoms:

Saline nasal spray. Salt water sprayed into the nose many times a day rinses the inside of the nose.
Nasal corticosteroids. These nasal sprays help prevent and treat swelling. Examples include fluticasone (Flonase Allergy Relief, Flonase Sensimist Allergy Relief, others), budesonide (Rhinocort Allergy), mometasone and beclomethasone (Beconase AQ, Qnasl, others).
Decongestants. These medicines are available with and without a prescription. They come in liquids, tablets and nasal sprays. Use nasal decongestants for only a few days because they may cause worse stuffiness, known as rebound congestion.
Allergy medicines. For sinusitis caused by allergies, using allergy medicines might lessen allergy symptoms.
Pain relievers. Try acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin IB, others) or aspirin available without a prescription.

Use caution when giving aspirin to children or teenagers. Though aspirin is approved for use in children older than 3, children and teenagers recovering from chickenpox or flu-like symptoms should never take aspirin. This is because aspirin has been linked to Reye's syndrome, a rare but potentially life-threatening condition, in such children.

Antibiotics
Antibiotics don't treat viruses, which are the usual cause of acute sinusitis. Even if bacteria caused the acute sinusitis, called a bacterial infection, it might clear up on its own. So a health care provider might wait and see if the acute sinusitis gets worse before prescribing antibiotics.

But, if you have severe, worsening or long-lasting symptoms, your symptoms might need to be treated with antibiotics. Always take the whole course of antibiotics even after symptoms get better. Stopping antibiotics early might cause symptoms to come back.

Immunotherapy
For sinusitis caused or made worse by allergies, allergy shots might help. This is known as immunotherapy.
