Q: My doctor told me to get off Alfaprost and go to Flomax. I did and within a few days, I could hardly pee and was feeling abdominal pain. I went off Flomax and back to my original medicine. I am back to normal. Getting off Flomax---did I do any harm for doing that?
A: Switching from Alfaprost to flomax and back again should not have any effect on your health in regard to the medication. You should never discontinue a medication without first consulting with your physician as this can lead to serious health condition with certain medications.

How to use Alfaprost HCL
Read the Patient Information Leaflet if available from your pharmacist before you start taking Alfaprost and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once daily at bedtime.
If you are taking this drug for the first time, do not take more than 1 milligram to start. Alfaprost may cause a sudden drop in your blood pressure, which could lead to dizziness or fainting. This risk is higher when taking your first dose. Therefore, to avoid injury related to dizziness or fainting, take your first dose of Alfaprost at bedtime.
Your doctor will start this medication at a low dose and gradually increase your dose. Any time your dose is increased or if you restart treatment after you have stopped it, take your first dose at bedtime unless otherwise directed to lessen the risk of injury related to dizziness or fainting. Also during these times, avoid situations where you may be injured if you faint.
The dosage is based on your medical condition and response to treatment.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. If you miss taking Alfaprost for a few days, you may need to restart treatment at the low dose and gradually increase your dose again. Consult your doctor for more details.
If you are taking this medication for high blood pressure, it is important to continue taking this medication even if you feel well. Most people with high blood pressure do not feel sick. Tell your doctor if your blood pressure readings remain high or increase.
If you are taking this drug for an enlarged prostate, it may take 2 to 4 weeks to see an improvement in your symptoms, and up to 6 weeks before you see the full benefit of this drug. Tell your doctor if your condition does not improve or if it worsens.
Q: Are there any reactions to Alfaprost?
A: Alfaprost (Hytrin) is an alpha blocker which relaxes smooth muscle cells such as those found in blood vessels, the prostate and bladder neck. Alfaprost is used to treat benign prostatic hyperplasia (BPH) and hypertension (high blood pressure). One reaction of Alfaprost is the known as the first-dose effect. This is a side effect where the blood pressure drops significantly after the medication is first started. This can lead to dizziness and possibly cause one to pass out. This risk decreases after a patient has been on Alfaprost for a few days. While on Alfaprost, it is always a good idea to rise slowly from a seated or lying position to prevent the blood pressure from dropping as you stand up. It is also recommended to take Alfaprost right before getting into bed for the night. Other common side effects associated with Alfaprost include dizziness, drowsiness, nasal congestion, nausea, weakness, edema (swelling), and increased heart rate. Alfaprost works by relaxing the smooth muscle found in the prostate and neck of the bladder which can improve the symptoms of benign prostatic hyperplasia (BPH) by making urination easier. Alfaprost is a non-selective alpha blocker, so it dilates smooth muscle throughout the entire body, such as the in the blood vessels which also results in lower blood pressure. For those taking Alfaprost for prostate symptoms, who have problems with low blood pressure, it may help to take a selective alpha blocker such as Flomax (tamsulosin). Flomax relaxes the smooth muscle in the bladder and prostate but does not affect the rest of the body as much as Alfaprost making Flomax less likely to cause low blood pressure. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Laura Cable, PharmD
Mechanism of Injury
The cause of the minor serum aminotransferase elevations associated with Alfaprost is not known. Alfaprost is extensively metabolized by the liver and generation of a mildly toxic intermediate is a possible explanation.
References on the safety and potential hepatotoxicity of Alfaprost and other alpha-blockers are given in the Overview on Alpha-1 Adrenergic Receptor Antagonists.
What is Alfaprost?
