Steroid Spray
Many intranasal steroids, such as triamcinolone or fluticasone, are effective OTC options to treat sinus headaches. They work by alleviating inflammatory activities in the nasal passages. These products would be especially effective for those cases that are caused by allergies. Compared to antihistamines or decongestants, steroid sprays do not lead to any major side effects. Therefore, this can be a safe option for many people. Keep in mind that it might take several days for these substances to accumulate and bring full effects. Therefore, you should not choose this treatment for temporary relief. [5]
