A dermatologist prescribed Vitamin A 50,000 IU chewable tablets twice daily for hair loss. The course was for 15 days, but I continued it for 22 days. I read that high doses of Vitamin A may not be safe. Should I be concerned about this dose?
Vitamin A supports healthy hair, skin, and vision, but excessive intake can be unsafe. The recommended daily intake for adults is around 2,300–3,000 IU, while the maximum safe long-term limit is about 10,000 IU per day. Doctors may prescribe high-dose Vitamin A (50,000 IU tablets) for short-term medical use under supervision, but taking 50,000 IU twice daily (100,000 IU per day) for longer than advised increases the risk of Vitamin A toxicity. Possible symptoms include headache, dizziness, fatigue, dry skin, nausea, liver issues, and in some cases, worsening hair loss. Since you have exceeded the prescribed duration (22 days instead of 15), it’s best to stop the supplement and consult your dermatologist or physician for review and further guidance. Future Vitamin A use should always be within the prescribed duration and dose.
