Common questions about Qvar Inhaler (FAQ)
Q: How quickly should I expect to notice a change after starting Qvar Inhaler?
A: Qvar Inhaler is a maintenance medication, and its full effects take time to develop. Official product information indicates that improvements in lung function are generally apparent within one to four weeks after starting therapy. It is not intended for immediate relief of sudden symptoms.
Q: What happens if I accidentally swallow some of the Qvar Inhaler mist?
A: Official instructions require rinsing the mouth with water and spitting it out after using the inhaler. This protocol is intended to help reduce the risk of localized infections, such as oral thrush. While the medication is designed to have low systemic exposure at therapeutic doses, this rinsing step is described in the official administration protocol.
Q: If I miss a dose of Qvar Inhaler, what is the best thing to do?
A: The official administration protocol advises that if a dose is missed, patients should take the next dose at the regularly scheduled time. The protocol specifies that a double dose should not be taken to compensate for a missed dose.
Q: Can using Qvar Inhaler make me more susceptible to infections?
A: Regulatory safety information notes that patients using corticosteroids, which are drugs that suppress the immune system, are more susceptible to certain infections. The official label notes that caution is warranted in patients with existing systemic infections (e.g., tuberculosis or viral conditions).
Q: Can Qvar Inhaler affect my vision?
A: Regulatory documents indicate that long-term use of inhaled corticosteroids may be associated with the potential for systemic effects on the eyes. This includes the possibility of developing cataracts and glaucoma.
Q: Does Qvar Inhaler have a strong effect on the rest of the body, or just the lungs?
A: The medicine is specifically formulated as an extrafine particle aerosol so that its action is primarily focused locally on lung tissue to control inflammation. However, regulatory documentation notes the potential for systemic effects of this corticosteroid, which include the possibility of adrenal suppression, particularly at higher than recommended doses.
Q: Are there any warnings about Qvar Inhaler use and glaucoma?
A: Glaucoma is listed in the official safety documentation as a potential serious adverse reaction associated with the long-term use of inhaled corticosteroids. This is noted under the systemic effects of the medication.
Q: How long does the medication in Qvar Inhaler last once the canister is opened?
A: The official disposal instructions describe discarding the inhaler when the dose counter reads zero or after the expiration date printed on the label, whichever occurs first.
Q: Can Qvar Inhaler cause weight gain?
A: Regulatory documentation notes the rare potential for systemic corticosteroid effects, such as Hypercorticism or Cushingoid features. These effects are typically associated with increased exposure and may involve changes in body composition.
Q: Is it true that Qvar Inhaler can cause hoarseness or a sore throat?
A: Yes, official regulatory documents list Pharyngitis (sore throat) and Dysphonia (hoarseness) as common adverse reactions associated with Qvar Inhaler use.
Q: Does Qvar Inhaler interact with cold and flu medicine?
A: Patients are instructed in official guides to tell their healthcare provider about all medicines they take, including both prescription and over-the-counter medicines.
Q: Can Qvar Inhaler affect my ability to drive or operate machinery?
A: Regulatory documents list uncommon nervous system adverse reactions, including reports of tremor or vertigo (a type of dizziness). Official documents list these reactions under nervous system disorders.
Q: Is Qvar Inhaler safe to use during pregnancy?
A: The official regulatory stance states that use during pregnancy should only be considered if the potential benefit is thought to justify the potential risks. Available human data do not establish the presence or absence of drug-associated risk to the fetus.
Q: Are there any specific foods or drinks I should avoid while using Qvar Inhaler?
A: Official information does not specify any particular foods or non-alcoholic drinks to avoid. However, the medicine is noted to contain a small amount of ethanol (alcohol) as an inactive ingredient, though regulatory documents state this small amount will not have any noticeable effects.
Q: Can Qvar Inhaler be used for conditions other than asthma?
A: Qvar Inhaler is formally indicated for the long-term maintenance treatment of asthma in patients who are four years of age or older. Official product information does not list indications for other conditions.
Q: Does Qvar Inhaler affect blood sugar levels?
A: Studies have examined the effects of inhaled corticosteroids on blood glucose. Some research has documented a rise in peak blood glucose concentration following a glucose challenge in normal subjects using high doses of inhaled beclomethasone dipropionate.
Q: Is it common to feel jittery or shaky after using Qvar Inhaler?
A: Jitteriness or shakiness falls under the category of tremor. Regulatory documentation lists tremor as an uncommon adverse reaction related to nervous system disorders.
Q: Does Qvar Inhaler contain lactose or any common allergens?
A: The active ingredient is beclomethasone dipropionate, formulated with the propellant HFA-134a and ethanol. The product is formally contraindicated for those with a known allergy or severe hypersensitivity to beclomethasone dipropionate or any other ingredient in the product.
Q: What is the risk of osteoporosis associated with Qvar Inhaler?
A: The long-term administration of inhaled corticosteroids has been associated with the potential for decreases in bone mineral density (osteopenia) and the potential for osteoporosis. Official documents state that patients with risk factors for decreased bone mass are to be monitored.
Q: How does the beclomethasone in Qvar get absorbed into the body?
A: The medicine is specifically designed as an extrafine particle aerosol solution. This fine particle size helps the medicine reach both the large and small airways for localized action. This formulation is intended to allow for effective local concentration while resulting in low systemic exposure at therapeutic doses.
Q: Does Qvar Inhaler interact with non-prescription supplements like vitamins or herbs?
A: Official guidance advises patients to tell their healthcare provider about all of the medications they take. This includes all prescription and over-the-counter medicines, as well as vitamins and herbal supplements, to check for potential interactions.
Q: What is the total number of doses in a Qvar Inhaler canister?
A: The total number of doses depends on the specific product and strength prescribed. However, canisters typically provide either 100 or 120 inhalations, a count that is displayed on the dose counter.
Q: Does Qvar Inhaler cause thinning of the skin?
A: Thinning and bruising of the skin have been reported as potential systemic adverse effects related to the chronic use of inhaled corticosteroids.
