Tamsulosin, used to treat benign prostatic hyperplasia (BPH), commonly causes dizziness, lightheadedness, and low blood pressure, especially when standing up suddenly. Finasteride, used to treat BPH and male pattern baldness, may reduce libido and cause erectile dysfunction. Combining these medications increases the likelihood of experiencing these side effects.
Dizziness and fainting: Rise slowly from a lying or sitting position to minimize dizziness. Avoid activities requiring alertness if you feel dizzy. Inform your doctor if dizziness persists or worsens.
Sexual side effects: Reduced libido and erectile dysfunction are possible. Discuss these concerns openly with your doctor; alternative treatments may be available.
Other potential side effects: Both medications can cause fatigue and headaches. Finasteride may rarely cause breast tenderness or enlargement. Tamsulosin can sometimes lead to nasal congestion.
Important Interactions: Inform your doctor about all medications you are taking, including over-the-counter drugs and supplements. Certain medications can interact with tamsulosin and finasteride, potentially increasing the risk of side effects.
Consult your doctor immediately if you experience severe dizziness, fainting, chest pain, or allergic reactions (rash, itching, swelling).
