Lipitor is a medication used to treat high cholesterol and is available in different strengths, including 10mg, 20mg, 40mg, and 80mg. According to Health Central [3], it is safe to split Lipitor tablets to achieve smaller doses. This is a common practice known as pill splitting, which can help reduce the cost of medication. However, it is important to consult with a doctor or pharmacist before splitting any medication.

It is worth noting that not all medications can be safely split, as some have a special coating or are extended-release formulations that should not be altered. Therefore, it is important to verify that the medication is safe to split before doing so. According to GoodRx [2], Lipitor tablets can be split as long as they are not extended-release formulations.

Additionally, it is important to use a pill splitter to ensure that the medication is divided evenly and accurately. According to Drug Patent Watch [1], Lipitor's patent expired in 2011, which means that generic versions of the medication are available. This can also help reduce the cost of the medication.

In conclusion, Lipitor tablets can be safely split into smaller doses as long as they are not extended-release formulations. However, it is important to consult with a doctor or pharmacist before doing so and to use a pill splitter to ensure accurate dosing. It is also worth considering the use of generic versions of the medication to reduce costs.
