In come cases, a medicine called cimetidine has proven helpful for treating common warts. When it works, the primary effects of cimetidine for warts include the eventual disappearance of the warts, though an individual may also experience the intended effects of the drug as well — the drug is typically used in treating ulcers and other gastrointestinal issues and reduces stomach acidity. Though the medication is usually well tolerated, it may cause side effects, including drowsiness, headaches, and diarrhea.

Cimetidine is a drug that is most commonly used for treating ulcers and heartburn, but can also be used for the treatment of warts. The drug is usually recommended for its ability to help reduce acid levels in a person’s stomach. When cimetidine is used for treating warts, however, it is taken orally instead of applied directly to the wart as many other treatments are. An individual who wants to use this alternative treatment can purchase cimetidine over the counter. He may do well, however, to discuss this treatment option with a doctor before he begins self-treatment.


Studies of the effects of cimetidine for warts have produced varied results. Some study participants responded to the medication and had noticeable improvement in their warts within just weeks of using the medication. Others, however, had little improvement after using the medication. Since using cimetidine on warts are not always reliable, it may be recommended in combination with a topical treatment for warts or as a home remedy to try before seeking the advice of a doctor.

There is some disagreement when it comes to the amount of cimetidine necessary for treating warts. Some people assert that taking 300 mg of cimetidine twice a day will help to get rid of warts. Others say a higher dose, such as 600 mg twice daily, is more likely to produce the desired effect. An individual may do well to discuss the dosage with his doctor since he will take the medication in a different manner than is listed on the label. By discussing the dosage with his doctor, he can be sure the drug will not interfere with any other medications he is taking or cause serious health effects.

In addition to the positive effects of cimetidine for warts, some people may also experience negative effects. Though many people tolerate the medication well, side effects are possible. For example, a person may develop headaches as a side effect or feel overly drowsy. Some people also develop diarrhea when they are taking this medication.

"As far as I know though, it hasn't been proven that cimetidine works. It might be acting like a placebo. There needs to be more studies done on it."

No placebo. It works!

I used this formula on my 8 year old and it worked well! Cimetidine in doses of 30 to 40 mg per kg of body weight per day can be effective in treating plantar warts.

I've researched this medication for my term assignment (I'm studying pharmacology).

Cimetidine can have lots of indirect effects. Lower stomach acidity can affect the absorption of nutrients and vitamins in the digestive system. It can also allow some bacteria to live and grow more easily in the digestive tract leading to gastro-intestinal symptoms. These can be things like diarrhea, constipation, flatulence, etc.

I've also read that long term use of cimetidine can lead to increased estrogen levels. This might be of concern for post-menopausal women.

@feruze-- Cimetidine suppresses a type of cell we have called T suppressor cells that are responsible for weakening the immune system. So cimetidine helps strengthen the immune system which in turn is able to fight the virus causing the warts better. This is how cimetidine is said to treat warts.

As far as I know though, it hasn't been proven that cimetidine works. It might be acting like a placebo. There needs to be more studies done on it.

I have taken cimetidine for my stomach and I can't believe the same medication can be used for warts.

I know that cimetidine works by inhibiting histamine which causes stomach acidity. But how does this relate to warts?
