Hello,
I can understand your concern. Triphasil has side effects related to upset stomach and intermittent vaginal spotting, tender breasts etc. However, it is not known to cause numbness of lips. It is just a co-incidence that you have developed
lip numbness after starting the medicine to delay periods. You do not need to stop taking it. If it is associated with swelling of the lip,
shortness of breath, slurred speech etc., then it might be an
allergic reaction to the medicine and you have to stop taking it immediately while contacting a doctor for emergency care regarding the reaction.
Other reasons for lip numbness could be exposure to sudden temperature changes, mild allergic reaction to some substance, trauma to the lips resulting in damage to the nerve,
Vitamin B12 deficiency etc. If the numbness persists or worsens, you should contact a
neurologist for examination and further investigations.
I hope this information helps you. Thank you for choosing HealthcareMagic. Let me know if you have follow up questions.
Best,
Dr. Viraj Shah
