Allergies Home > Qnasl Warnings and Precautions
Before beginning allergy treatment with Qnasl, your healthcare provider will need to know if you have any type of infection or if you have glaucoma or cataracts, among other conditions. Safety precautions associated with Qnasl also include warnings for women who are pregnant or nursing. Additionally, this nasal spray may cause nasal ulceration (sores) or even perforation of the nasal septum in some people.
What Should I Tell My Healthcare Provider?You should talk with your healthcare provider prior to using Qnasl™ (beclomethasone nasal aerosol) if you have:
- Tuberculosis, herpes, or any other infection
- Not had chickenpox or the measles, and have not been vaccinated against them
- Recently had nasal surgery
- Sores or injury to the inside of your nose
- Glaucoma or cataracts
- Any allergies, including to foods, dyes, or preservatives.
- Pregnant or thinking of becoming pregnant
Specific Precautions and Warnings With QnaslSome warnings and precautions to be aware of prior to using this nasal spray include the following:
- In studies, there were many cases of nosebleeds and a few cases of nasal ulceration (sores) or even perforation of the nasal septum (the cartilage that divides the nose in two halves, between the nostrils). Let your healthcare provider know right away if you develop nosebleeds or nasal sores, as catching them early may help prevent nasal septum perforation. Also, avoid spraying the medicine toward the nasal septum; instead, aim the spray toward the outside of the nostrils.
- Qnasl is a steroid and may suppress the immune system. Although this is more likely to occur with oral or injectable steroids, it is still possible with nasal steroids like Qnasl.
Taking steroids may increase your risk for infections. Certain infections, such as chickenpox or the measles, may be more dangerous if you are using this nasal spray. Let your healthcare provider know right away if you are exposed to chickenpox or the measles if you have not had these infections and have not been vaccinated against them.
- Qnasl may increase the risk of thrush (a fungal infection) in the mouth, nose, or throat. Let your healthcare provider know if you develop white patches or red areas.
- Qnasl may increase the risk of glaucoma and cataracts. Let your healthcare provider know if you have any changes in vision. Regular eye exams are also probably a good idea.
- If you are switching from an oral steroid to Qnasl (which is a nasal steroid), your healthcare provider should slowly decrease your dose of the oral steroid. Stopping an oral steroid too quickly can be dangerous.
- This medication can suppress the body's ability to make natural steroids. This usually happens when too much Qnasl is used or if you are very sensitive to the medication. In these circumstances, Qnasl should be stopped gradually to give your body a chance to begin making natural steroids again.
- Before starting Qnasl, make sure to tell your healthcare provider if you currently have any type of infection. Also, let him or her know if you have ever had tuberculosis or a herpes infection of the eye; this drug may weaken the immune system, allowing these infections to worsen.
- Like all steroids, Qnasl may slow down the growth rate of children and teenagers. Contact your child's healthcare provider if you are concerned about a slow growth rate in your child.
- Corticosteroids, including Qnasl, can slow healing. Therefore, if you have had recent nasal surgery or nasal sores, you should wait until healing has occurred before using Qnasl. Also, corticosteroids can cause nosebleeds and nasal sores or irritation.
- Qnasl appears to be unlikely to interact with other medications (see Qnasl Drug Interactions).
- Qnasl is a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are currently unknown (see Qnasl and Pregnancy).
- It is unknown if beclomethasone, the active ingredient of Qnasl, passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to using the product (see Qnasl and Breastfeeding).
