Brief Answer:
omnexel can cause dizziness.

Detailed Answer:
Hello dear welcome to HCM forum.
Thanks for posting to us.

Omnexel contains tamsulosin as the active ingredient. This an sympathetic blocker that can cause side effects like postural hypotension, dizziness, vertigo, fainting etc because of vasodialatation and peripheral pooling of blood.

But this is a very commonly used drug for conditions like prostatic hypertrophy and most patients tolerate the drug without difficulty.

If you are feeling too uncomfortable,you can discuss the issue with your doctor.

Meanwhile, drink enough fluids, and avoid prolonged standing.

The other product you mentioned is a herbal preparation of which detailed side effect profile is not available though it is less likely to cause such symptoms.

Hope this will answer your query.
Be free to ask further questions if any.
Wishing you good health.
Thank you.
