Q :

I have been prescribed Sativex to help with the pain and spasms I have with the MS. I have been trying to use this spray when needed, but am finding that it is dufficult to get the dose under your tongue, or on your cheek . I was told that the bottle was to be sprayed upright and to shake gently before usage. Please any info on how to correctly use this spray would be appreciated. I was told that the vials were to be refrigerated before opening and am concerned as the box of vials was not refrigerated when I picked them up from the pharmicist.

A :

Sativex is a mouth spray developed by the company GW Pharmaceuticals for multiple sclerosis patients to relieve neuropathic pain and spasticity.
SATIVEX® is a solution supplied in small vials as a buccal spray. As you describe, you administer the spray, under the tongue or inside the cheeks, cautiously establishing the best dose for reducing your pain through titration up to a tolerated dose. Since you are having difficulty administering the medication I suggest you speak with your doctor or with your pharmacist. Ask them to observe your technique while you administer the spray. It is much easier to make appropriate recommendations after observing your technique. As well they can assess if there are other barriers preventing you from administering the spray correctly.
Unopened bottles should be stored in the refrigerator. Do not freeze the bottles. Keep away from sources of heat such as direct sunlight or flames (as the product is flammable). Opened bottles may be stored at room temperature. Any unused contents should be discarded after 28 days. Inform your pharmacist of your concern that your medication was not refrigerated when you picked it up. I am sure they will have a reasonable explanation.
