Question
Posted on: May 8 2014Is Carbol acid (phenol)) necessary in a Coll odium with salicylic acid against warts?
A physician prescribes a Coll odium with the following ingredients
R
Salicylic Acid powder 4.5 g
Lactic acid 4.5 g
Carbol acid 0.6
Coll odium with castor oil AD 30 mL
S/In warts, 1 x per day
Our question is whether carbol acid can be processed in this preparation?
It is too high a concentration to be used as a preservative, but it can be keratolytic.
Is this necessary, however, in this preparation?
Can it form interactions with the active ingredients?
If it can be used, should an antioxidant be attached?
This preparation is also non-refundable. Without carbol acid, it will be refunded.
Answer
The doctor has good intentions if he prescribes phenol without estimating the consequences on the intervention of the RIZIV in the cost price. It is obviously an aggressive product and will help remove the wart. I can be difficult instead of the doctor acting and so just give the admission to not add the phenol. You have to discuss this with the prescriber. You can suggest him just increase the amount of lactic acid. But he decides.
If you need to maintain it in the composition, use anhydrous phenol, not phenolum liquefactum. Phenol will not interact with the other products in the composition and does not require antioxidants.
