Because they target different biological pathways, they do not interfere with each other's absorption or metabolism.

Ensure you follow the specific instructions for each: apply minoxidil to the scalp as directed and take the Propecia tablet at the same time each day.

Important precautions
Back to contentsPregnancy and handling the medication
Women who are or may be pregnant must not handle crushed or broken tablets. The active ingredient can be absorbed through the skin and cause serious birth defects in male babies.
Mental health and mood changes
Stop taking this medicine and see your doctor immediately if you experience depression, self-harming thoughts, or suicidal ideation. These side effects can occur even after stopping treatment.
Heart conditions and chest pain
Stop use and seek medical help if you experience chest pain, a rapid heartbeat, faintness, or sudden unexplained weight gain, as the medicine can affect your heart rate and blood pressure.

Can I take Apixaban and Levomepromazine together?
Taking apixaban and levomepromazine together may increase your risk of bleeding. Levomepromazine can sometimes cause a drop in the number of platelets in your blood (the cells that help your blood clot). When combined with a blood thinner like apixaban, this makes it easier for you to bruise or bleed. Additionally, levomepromazine can cause side effects like dizziness or fainting when you stand up, which increases the risk of falls and subsequent injury while on a blood thinner.
