Drug Interactions between azelastine / fluticasone nasal and dasabuvir / ombitasvir / paritaprevir / ritonavir

Talk to your doctor before using ritonavir together with fluticasone nasal. Combining these medications may increase the absorption of fluticasone nasal into the blood stream. You may be more likely to experience side effects such as swelling, weight gain, high blood pressure, high blood glucose, muscle weakness, depression, acne, thinning skin, stretch marks, easy bruising, bone density loss, cataracts, menstrual irregularities, excessive growth of facial or body hair, and abnormal distribution of body fat, especially in the face, neck, back, and waist. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Other side effects that may occur include decreased ability to fight infections, increased risk of developing infections, and inadequate response to stress such as infection, surgery, trauma, or a severe asthma attack. Children may experience a reduced growth rate due to excessive effects of fluticasone nasal. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
