- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
It is POSSIBLY UNSAFE to take masterwort by mouth if you are breast-feeding. It's best to avoid use.
Exposure to ultraviolet (UV) light including sunlamp treatment for certain skin conditions such as psoriasis, use of tanning beds, or time in sunlight: Masterwort causes sensitivity to ultraviolet (UV) light. It could cause your skin to burn. Don't use masterwort if you are receiving UV light therapy. Also, stay out of the sun and avoid tanning beds if you are taking masterwort.
Medications that increase sensitivity to sunlight (Photosensitizing drugs)Interaction Rating: Moderate Be cautious with this combination.Talk with your health provider.
Some medications can increase sensitivity to sunlight. Masterwort might also increase your sensitivity to sunlight. Taking masterwort along with medication that increase sensitivity to sunlight could increase the chances of sunburn, blistering, or rashes on areas of skin exposed to sunlight. Be sure to wear sunblock and protective clothing when spending time in the sun.
Some drugs that cause photosensitivity include amitriptyline (Elavil), Ciprofloxacin (Cipro), norfloxacin (Noroxin), lomefloxacin (Maxaquin), ofloxacin (Floxin), levofloxacin (Levaquin), sparfloxacin (Zagam), gatifloxacin (Tequin), moxifloxacin (Avelox), trimethoprim/sulfamethoxazole (Septra), tetracycline, methoxsalen (8-methoxypsoralen, 8-MOP, Oxsoralen), and Trioxsalen (Trisoralen).
The appropriate dose of masterwort depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for masterwort. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
