When combining Lipitor (atorvastatin) with blood pressure (BP) medications, there are a few potential side effects to be aware of. According to Drugs.com, some of the most common side effects of Lipitor include diarrhea, upset stomach, and muscle or joint pain [1]. When taken with BP medications, there is a possibility of these side effects becoming more pronounced or new side effects developing.

One potential side effect of taking Lipitor with BP meds is an increased risk of muscle damage, known as rhabdomyolysis [1]. This risk is higher when Lipitor is taken in combination with certain BP medications, such as fibrates or niacin [1]. Symptoms of rhabdomyolysis include muscle pain, weakness, and dark or reddish-brown urine [1]. If you experience any of these symptoms, it is important to seek medical attention immediately.

Another potential side effect of taking Lipitor with BP meds is an increased risk of liver damage [1]. While this side effect is rare, it is important to monitor liver function regularly when taking Lipitor, especially when it is taken in combination with BP medications [1].

It is also worth noting that Lipitor can interact with certain BP medications, such as calcium channel blockers, leading to an increased risk of side effects [2]. For example, taking Lipitor with amlodipine (a calcium channel blocker) can increase the risk of muscle pain and weakness [2].

In summary, when taking Lipitor with BP meds, it is important to be aware of the potential side effects and to monitor liver function regularly. Additionally, it is important to be aware of potential drug interactions and to speak with a healthcare provider if any new or worsening symptoms develop.
