Qvar Warnings and Precautions
Before starting treatment, make sure you are aware of the precautions associated with the use of Qvar. Warnings and precautions include watching out for potential drug interactions, letting your healthcare provider know if you are pregnant or breastfeeding, and being aware that Qvar cannot replace fast-acting rescue inhalers. Qvar may potentially suppress the immune system, cause glaucoma or cataracts, worsen your asthma symptoms, or slow the growth of children and teenagers.
You should talk with your healthcare provider prior to taking Qvar® (beclomethasone inhaler) if you have:
- Not had chickenpox or the measles (or have not been vaccinated against them)
- Eczema (or atopic dermatitis)
- Tuberculosis, herpes, or any other infections
- Glaucoma or cataracts
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Some warnings and precautions to be aware of with Qvar include the following:
- If you are switching from an oral steroid to Qvar (which is an inhaled steroid), your healthcare provider should decrease your dose of oral steroid very slowly. Stopping an oral steroid too quickly can be very dangerous.
- Qvar is not a fast-acting asthma medication and cannot replace fast-acting rescue inhalers. Do not use Qvar to treat an asthma attack. Everyone taking Qvar should also have a rescue asthma medication available at all times. Let your healthcare provider know if you need to use your rescue inhaler more frequently than usual, as this may be a sign of worsening asthma.
- Qvar can cause an immediate worsening of asthma symptoms. If this happens, use your rescue inhaler (such as albuterol) as needed and contact your healthcare provider for further instruction.
- Qvar is a steroid and may suppress the immune system. Although this is more likely to occur with oral steroids, it is still possible with inhaled steroids (such as Qvar). You may be at a higher risk for infections. Certain infections (such as chickenpox or the measles) may be more dangerous if you are taking Qvar. 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).
- Like all steroids, Qvar may slow the growth of children and teenagers. Usually, this slowing of growth is small, with children growing about half a centimeter less per year. Contact your child's healthcare provider if you are concerned about slow growth in your child.
- Inhaled steroids (including Qvar) can cause glaucoma or cataracts (conditions of the eyes).
- Before starting Qvar, be sure to tell your healthcare provider if you currently have any type of infection. Also, let your healthcare provider know if you have ever had tuberculosis or a herpes infection of the eye, as Qvar may weaken the immune system, allowing these infections to worsen.
- Qvar can interact with other medications (see Qvar Drug Interactions).
- Qvar is considered a pregnancy Category C medication. This means that it may not be safe to use during pregnancy. Talk to your healthcare provider about the risks and benefits of using Qvar during pregnancy (see Qvar and Pregnancy for more information).
- Qvar may pass through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, be sure to talk with your healthcare provider about using Qvar (see Qvar and Breastfeeding for more information).
