In our practice, we often get questions about how certain medications affect foot health. Today, we are going to discuss alpha-blockers.
What is an alpha-blocker medication?
Alpha-blockers, also known as “blood pressure medications” and “calcium channel blockers” are a class of medication primarily used to relax certain muscles and help small blood vessels remain open. They work by blocking the action of norepinephrine, a hormone that narrows blood vessels and tightens the muscles around the bladder and prostate. Blood pressure medications do have some side effects but they also reduce your risk of heart disease, stroke, or heart attack.
What are alpha-blockers used for?
Alpha blocker medication is commonly prescribed for conditions such as high blood pressure (hypertension) and/or an enlarged prostate (benign prostatic hyperplasia).
Some of the most well-known alpha-blockers include:
- Tamsulosin (Flomax)
Flowmax is commonly used to treat symptoms of an enlarged prostate - Doxazosin (Cardura)
Cardura is used to treat high blood pressure and symptoms of BPH. - Terazosin (Hytrin)
Hytrin is also used to lower high blood pressure and BPH symptoms. - Alfuzosin (Uroxatral)
Uroxatral is most often used to treat BPH. - Prazosin (Minipress)
Minipress is a common treatment option for high blood pressure but is also sometimes used to treat PTSD-related nightmares.
How can alpha-blocker medications affect your foot health?
Firstly, there is one upside: improved blood circulation.
Since alpha-blockers work by relaxing the smooth muscles in the blood vessels, they give the patient improved blood circulation. This improvement in circulation can benefit your feet, promoting better oxygen and nutrient delivery, which is critically important for the health and repair of tissues.
For anyone with peripheral artery disease or diabetes, maintaining optimal blood flow is particularly important to prevent complications.
The downsides of Alpha-Blockers on your feet
While alpha-blockers are effective in treating certain health issues, they have possible side effects that could affect your stability and foot health. These include:
Dizziness and Fatigue
These medications can cause dizziness and fatigue, increasing the risk of falls. A fall can lead to foot injuries such as fractures or sprains.
Orthostatic Hypotension
This condition, a form of low blood pressure that occurs when standing up quickly, can also heighten the risk of falling.
Being aware of these risks can help you take precautions, such as getting up slowly or using support when standing.
Peripheral Edema
Peripheral edema, or swelling in the feet and ankles, is another common side effect of alpha-blockers. This swelling can cause discomfort and lead to further complications, such as skin changes and an increased risk of infection. Managing edema often involves elevating the feet, reducing salt intake, and possibly using compression stockings. Regular check-ups with our podiatrists can go a long way in helping you successfully manage and mitigate these potential issues.
There are other causes of peripheral edema, including heart failure, weak veins in your lower legs, or kidney or liver problem
Ankle numbness
Alpha-blockers don’t commonly cause ankle numbness as a direct side effect, though some patients have reported this issue. Ankle numbness is usually associated with nerve compression or circulatory problems.
However, as we discussed above, alpha-blockers can cause side effects like cramping, drowsiness, tiredness and lightheadedness, which might alter your walking pattern or posture, which could indirectly lead to nerve pressure.
If you’re experiencing ankle numbness, consult your podiatrist to determine the exact cause and the most appropriate treatment for it.

What’s the best plan of action? Monitor your condition and consult your podiatrist
If you are taking alpha-blockers and notice changes like foot and ankle swelling, pain, or falls-related issues, it is crucial to consult your podiatrist or health care provider. It is better to be safe than sorry when it comes to your health. Please be proactive and don’t wait if you suspect any issues and you should never stop a blood pressure medication without medical advice.

FAQs
Can ACE inhibitors cause foot pain?
ACE inhibitors typically don’t cause foot pain directly but they can lead to side effects that might indirectly affect the feet, including swelling (edema)
What other medications can cause swollen feet and ankles?
Over-the-counter NSAIDs, hormones used in birth control and hormone replacement therapy, certain diabetes medications and some antidepressants also frequently lead to swelling and fluid retention. Diuretics (water pills) may be prescribed to help reduce swelling.
