It looks like your message got cut off after “may cause blood clots and…”.
If you’re talking about certain tablets (medications), especially things like hormonal contraceptive pills (birth control pills) or some hormone therapies, then yes—some of them can slightly increase the risk of blood clots, but this depends a lot on:
- the exact medication
- the dose and type of hormones
- your personal risk factors (smoking, age, obesity, history of clots, etc.)
Not everyone has the same risk, and for most healthy people the absolute risk is still low—but it is taken seriously by doctors.
However, I don’t want to guess what “these tablets” are without more context.
Can you tell me:
- the name of the tablets, or
- what they are used for?
Then I can explain the risks properly and safely.
