Flomax Overdose
As with any medication, it is possible to overdose on Flomax. Some common signs or symptoms of a Flomax overdose can include lightheadedness, dizziness, or fainting. The effects of a Flomax overdose can vary depending on several factors, such as how much of the medication was taken and whether it was taken with any other medications, alcohol, and/or drugs. Some treatment options can include pumping the stomach or administering medications to increase blood pressure.

Flomax® (tamsulosin hydrochloride) is a prescription medication that has been licensed to treat an enlarged prostate (known medically as benign prostatic hyperplasia, benign prostatic hypertrophy, or BPH). As with all medicines, it is possible to take too much Flomax. The effects of a Flomax overdose will vary depending on a number of factors, including how much Flomax was taken and whether it was taken with any other medicines, alcohol, and/or drugs.
If you happen to overdose on Flomax, seek medical attention immediately.
The effects of a Flomax overdose may include:
- Headaches
- Low blood pressure when going from a sitting or lying down position to standing up (orthostatic hypotension).
This may cause signs or symptoms that include lightheadedness, dizziness, or fainting, especially when standing up.
Given that there have been so few cases of people taking too much Flomax, it is also not known what the best treatment is for a Flomax overdose. If the Flomax overdose was recent, the healthcare provider may use certain medicines or place a tube into the stomach to "pump the stomach." Treatment may also involve supportive care. This type of care consists of treating the symptoms that occur as a result of the overdose. For example, supportive treatment options for a Flomax overdose may include:
- Fluids through an intravenous line (IV)
- Medicines to increase blood pressure
- Other treatments based on the complications that occur.
It is important that you seek medical attention immediately if you believe that you may have overdosed on Flomax.
