Why this happens
Aspirin 75mg is an antiplatelet (blood thinner) used to prevent clots. Testogel (testosterone) can increase the production of red blood cells. While they do not interfere with how each other works in the body, your doctor will need to monitor your blood count and blood pressure to ensure the combination is managed safely.
What you should do
Back to contentsYou can take these together, but you should have regular blood tests as requested by your doctor to monitor your red blood cell count (haematocrit) and blood pressure. If you experience unusual bruising, persistent headaches, or dizziness, speak to your GP. It is best to avoid or strictly limit alcohol while taking aspirin, as the combination can increase the risk of stomach irritation or bleeding.

Patient picks for Drug interactions

Treatment and medication
Can I take Abilify and Fluoxetine together?
Taking fluoxetine with Abilify (aripiprazole) can significantly increase the amount of Abilify in your bloodstream. This makes you much more likely to experience side effects such as extreme sleepiness, restlessness (feeling like you cannot sit still), uncontrollable body movements (tremors or twitching), and dizziness. There is also a small but serious risk of a heart rhythm problem called QT prolongation.

Treatment and medication
Can I take Desmopressin and Ketoconazole together?
Taking these two medicines together can significantly increase the amount of desmopressin in your blood. This can lead to your body holding onto too much water, which can cause a dangerous drop in your blood salt levels (hyponatraemia). Symptoms to watch for include severe headache, nausea, vomiting, confusion, or feeling very drowsy.
