Get to Know Pso!
Home-based phototherapy
This is a question CPN gets regularly because phototherapy, though an effective treatment for many people with psoriasis (Pso), can be difficult to access, especially depending on where in Canada you live. Buying a home-based phototherapy device is a solution for some people but deciding what product to buy takes some consideration depending on your personal situation. It’s helpful to understand what phototherapy is and how it treats psoriasis as a start.
What is phototherapy?
Phototherapy is a common form of treatment that involves repeated exposure of the skin to specific ranges of UV radiation. Narrowband-UVB, which releases a narrower range of UV wavelengths, is the most common form of phototherapy treatment used, though there are two other types: PUVA in which psoralen (a drug taken orally or applied topically to the skin) is used to sensitize the skin to UVA radiation; and broadband UVB (which emits a broader range of UV wavelengths). In psoriasis, phototherapy works by slowing down the growth of skin cells.
Although phototherapy is generally offered in a doctor’s office or clinic, the number of clinics across Canada are limited and sessions may require attending appointments several times a week. Many people may consider purchasing phototherapy units that they can use at home.
Some private benefit plans reimburse the costs of home phototherapy units, though public plans generally don’t. It’s best to check what coverage you have if you’re considering a home phototherapy unit before you buy it so that you know if you’re able to seek reimbursement for the costs. Also keep in mind that phototherapy equipment is currently listed as an allowable Medical Expense Tax Credit under the Income Tax Act.
Though everyone is different and may find different devices more beneficial than others, some things to consider when determining what home phototherapy unit may be right for you include:
- On what part(s) of your body do you have psoriasis?
- What device(s) may be most appropriate for your needs?
- Are you able to maintain a detailed treatment schedule independently?
- Can you afford the cost of the device, bulb replacement, tax and any other related administrative costs?
