Oxsoralen Ultra oral Warnings
For the treatment of psoriasis, this medication should only be used for severe psoriasis that has not responded well to other treatments since this medication may cause serious side effects (such as cataracts, skin cancer/aging). Consult your doctor for more details.
This medication comes in different dosage forms which do not have the same effects. Do not switch between different dosage forms without talking to your doctor. Each time you get a refill, make sure that you receive the correct form of this medication that your doctor prescribed.
Oxsoralen Ultra oral Uses
This medication is used along with controlled ultraviolet light (UVA) to help control severe psoriasis. Methoxsalen works by making the skin more sensitive to UVA light. This combination helps to slow the overgrowth of skin cells.
This medication is not recommended for use in children younger than 12 years.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.
Read the Patient Information Leaflet if available from your pharmacist before you start taking methoxsalen and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Do not sunbathe for 24 hours before taking methoxsalen and having the UVA light treatment.
Take this medication by mouth with low fat food or milk, usually 90 minutes to 2 hours before your UVA light treatment or as directed by your doctor. Taking methoxsalen with food helps to increase absorption of the medication and also decreases nausea.
The dosage of methoxsalen is based on your weight, medical condition, and response to treatment. The amount and time of UVA light for each treatment is based on your skin type and response to treatment. You may have UVA light treatments 2 to 4 times a week when you first start and then less frequently as your condition improves.
For 24 hours after taking the capsule, during daylight hours wear wrap-around sunglasses which block out UVA light. This will prevent UVA rays from entering the eyes. UVA light can cause methoxsalen to bind to the lenses of the eyes, causing cataracts. Also, avoid sunlight (including sunlight through windows) on your skin or lips for at least 8 hours after taking methoxsalen. This will prevent the body from getting too much UVA rays which could lead to sunburns. If you cannot avoid sunlight, wear protective clothing (such as hat, gloves, long-sleeved shirt, pants) and/or sunscreen which blocks out UVA light. Consult your doctor or pharmacist for information on which sunscreen to use. Do not apply the sunscreen to areas of the skin affected by psoriasis until after the UVA light treatment.
During the UVA light treatment, follow all instructions given by the healthcare professional. After the UVA light treatment, do not sunbathe for at least 48 hours. Doing so may increase the risk of severe burns. Consult your doctor for more details.
Tell your doctor if your condition does not improve or if it worsens.
