<s>[INST] I was recently advised to changeover from Urimax 0.4 mg to Urimax-D along with Himalaya s Himplasia bpd. Since then I have been continously having mouth ulcers & dental infections. Is there any connection ? I am 66 years old and take Revelol Am 25/5 one per day. [/INST] Hello,There is no such side effects of Urimax-D. Mouth ulcers and dental infections are commonly caused by poor hygiene. Vitamin B12 and iron deficiency. You are suggested to get clinically assessed by a dentist and get treated at the earliest. In the meantime, take Vitamin B12 and use mouth wash after every meal. You are suggested to maintain good oral hygiene.Hope I have answered your question. Let me know if I can assist you further.
